Will the Chinook heavy transport helicopter celebrate its centenary?

47

Not a single western-made helicopter can take on as much cargo as a Chinook can take, and as such it will most likely remain in operation for several more decades to come.


The Chinook helicopter is scheduled to remain in service after its centenary, which will happen in 2060 year. Let's look at how Boeing is going to keep this workaholic at the forefront of operational capabilities.

Given the fact that the CH-47 Chinook helicopter from Boeing made its first flight at the beginning of 60-s, and the American army plans to exploit it further on 2060, it may well become the first in the world and may even be the only "century-old" helicopter .

The production of the Chinook heavy transport helicopter continues and has not stopped for more than 50 years, in aviation in this he was surpassed only by the Lockheed Martin transport aircraft C-130 Hercules. Having survived all his peers in the American army, he may well outlive many of those who came after him, because the army announced its plans to fly this heavy transport helicopter with longitudinal rotors “at least” until the 2060s, and possibly further.

At a briefing held at the Boeing plant in Philadelphia, Randy Rott, director of cargo helicopter development programs, explained the reasons for extending Chinook’s life and also outlined the company's plans to extend the life of the helicopter until its retirement day.

“Eighteen countries, including the United States, the United Kingdom, Japan, Canada, Italy, Australia, the Netherlands, Spain, Greece, South Korea, Argentina, the United Arab Emirates, Egypt, Thailand, Taiwan, Turkey, Libya and Morocco, operate today a Chinook helicopter, The world flies 900 such machines. This project and its capabilities are continuing; a large number of helicopters have been serving in these countries for quite a long time, ”he said.

The current priority program of the US Army has determined the total number of 473 helicopter Chinook. This number includes the new CH-47F models and the upgraded CH-47D (which have some components, such as rotor hubs, blades and transmissions repaired, and everything else is new). Of these, 319 machines were delivered in May 2015. The US Department of Defense is currently in the final stages of implementing its second multi-year contract on the CH-47F option, according to which 2013 helicopters must be made with 2017 to 155 (plus the 60 option, of which 25 has already been built), including machines for customers on the program of sales of military equipment abroad.

“Chinook is one of the few programs nowadays, which for almost every customer runs ahead of schedule. This is important, because a customer who wishes to receive a helicopter in the 2019 year should in no case receive it in the 2020 year, ”noted Rott.

The production line in Philadelphia is designed to produce 60 helicopters per year (the minimum economically viable volume of 36 helicopters per year); however, usually the cycle duration from issuing a contract to delivery to foreign customers is 36 months, although for the American army it can be only 24 a month, since the state issues orders for products with a long production time in advance. According to Rott, Boeing has enough orders for this time to produce the latest version of the CH-47F / MH-47G Chinook, which will run until the 2019 year.

“After 2019, we will most likely have to re-evaluate production volumes in order to understand what quantity will be at least not unprofitable, but the US army has reached a record, declaring its intention to exploit Chinook before 2060's. This is due to the fact that there is no other such aircraft that can (or plans to) provide these capabilities. ”

If the US Army plans to operate its Chinook helicopters until the 2060-s, then it must make several additional improvements over this period in order to continue to fly them. Since the flight of the first CH-47A helicopter in the 1962, the maximum gross mass of the Chinook has grown from 15000 to 23000 kg, demonstrating a decent growth in capabilities over time.

The UK is the largest operator of Chinook helicopters outside the United States.


The Chinook production line in Philadelphia will produce helicopters in the newest version of the CH-47F / MH-47G up to the 2019 year

As for the modifications of the CH-47D variant, which turn it into the CH-47F model, the most noticeable here are the glass cockpit and the DAFCS (digital automatic flight control system) digital automatic flight control system. “From an operational point of view, DAFCS has become the most significant improvement in the CH-47F, testimonials from users that we receive. This turns your ideas about what a helicopter can do - it is basically a control of sustainability. You can leave the helicopter after a hang, take a walk and it will just stand still, ”said Rott.

Another improvement to the CH-47F aircraft is to install the Cargo On and Off Loading System COOLS (Cargo On and Off Loading System) in the cargo hold, which replaced the HICHS (Helicopter Internal Cargo Handling System). The HICHS system used metal rollers on the floor to move the pallets, which meant that the helicopter was difficult to configure for other tasks. The COOLS system uses double-sided turning blocks, they are on one side flat, and on the other are rollers (a similar system is used in the Boeing C-17 Globemaster III transport aircraft). This not only allows you to easily configure the aircraft for different tasks, but also to leave under the system a ballistic defense that you had to shoot before.

The Chinook helicopter on the sides installed optional fuel tanks (see photo). Although they increase the range and duration of the flight, they affect the air flow downstream along the fuselage, which may affect the available payload.

Evolutionary update

As for the short-term improvements of the CH-47F helicopter, the American army is currently in the process of compiling a variant analysis of a possible modernization of the Block 2. “It will be an evolutionary process based on what has been done before with the goal of gaining increased opportunities, without having to reinvent the wheel and more importantly, without having to pay for it again,” said Rott, adding that “none of the proposed opportunities are not associated with high-risk technologies. ”

Although the modernization of the Block 2 is still being finalized, it will most likely include the advanced blade of the main rotor ACRB (Advanced Chinook Rotor Blade). ACRB is still under development; This is not a flat blade, it differs in geometry and a new asymmetrical aerodynamic profile in order to increase the lift force by approximately 900 kg per blade (5400 kg per helicopter).

The design principles were that in order to simplify the modernization, the first 45 centimeters of the blade, where it is attached to the sleeve, should be identical to the old blade (ACRB is made of the same materials as the old blade). “ACRB is currently undergoing a stage of presentations and large-scale models, according to the schedule it will be ready for installation on machines until about the 2019 of the year,” Rott said. “The project is funded by Boeing and the US Army, and we expect it to become part of not only the new Chinook helicopters, but also the existing platforms undergoing modernization.” Although the ACRB blade is designed to simplify the upgrade process, some refinement of the helicopter flight control software will be required.

In August 2015, the US Army announced that it expects to resume production of the Chinook MH-47G for special tasks in the updated Block 2 configuration. The US Army Special Operations Command (USASOC) is currently deploying an 61 upgraded MH-47G Block 1 helicopter (62 delivered: 35 CH-47D, nine MH-47D and 18 MH-47E; one was lost in Afghanistan) and one was lost in Afghanistan) and nine and nine were lost in Afghanistan) and nine and nine were lost in Afghanistan) MH-47G.

Production of the last eight MH-47G Block 1 helicopters is currently completed, but the American Army Aviation Systems Integration Directorate proposes to resume their production in order to supply an unnamed number of new Block 2 helicopters to replace some or all of the upgraded platforms to the Block 1 configuration.

It is expected that the Block 2 retrofit machines will go into service with the American army at the start of the 2020, although this will depend on government funding and other factors. After that, the previously released Chinook Block 1 helicopters will most likely be upgraded to Block 2 configuration in order to have all the machines of the same standard.

In addition to Block 2, the company plans to carry out one or even two Block-type upgrades of the current CH-47F / MH-47G models, planned by the army, for the Chinook helicopters, or by giving them the Block 3 prefix or the symbol CH-47H. “If Block 2 starts to go off the production line at the beginning of 2020's, and you have to build 500 machines, then they will be manufactured by about 2035 year. What happens to Chinook depends on where the FVL [Future Vertical-Lift] advanced heavy transport helicopter program is at that time, but if this is the initial development phase, you can proceed to Block 3, ”said Rott .

“Of course, we are already thinking about it, but it all depends on what you want to achieve, greater speed, range, payload, size of the cargo compartment, survivability, or all at once?”

One design feature that distinguishes the Chinook from any helicopter flying today (with the exception of another Boeing-Vertol 107 model) is its configuration with a longitudinal rotor arrangement. This feature provides superior lift and speed, and will be at the core of any future Block 3 or CH-47H upgrade program.

“The longitudinal scheme became the embodiment of the idea of ​​the designer of helicopters Frank Pyaseki. Within the relatively small area of ​​the projection of the two rotors, you have all the traction necessary for lifting, while at the same time a tail rotor is needed for a helicopter with a traditional rotor to counteract the jet torque, Rott explained. - Along with the increase in lift, the longitudinal scheme with a high raised rear pylon of the main rotor allows trucks to immediately drive into the ramp for loading, which is impossible for traditional helicopters. The pilot is also not so worried about the strength of the wind and the inclined landing sites, in addition, the helicopter is safer for ground personnel. A Chinook helicopter can also climb large heights with a heavier load. These are amazing opportunities and it is surprising to me why the project of a helicopter with a similar scheme has not really been implemented in other countries. ”

While many modern standard helicopters have moved from main rotors with two or three blades to rotors with four or five blades to increase speed and aerodynamic lift, Chinook stopped on its configuration of two main rotors on three blades. Rott explained: "The six blades of the two rotors, given their current length and width, create excellent lifting force."

“The Chinook 347 prototype, exhibited at Fort Rucker in Alabama, was an experimental platform, it had screws with four blades plus wings. During test flights in 1965, the possibility of obtaining additional speed and lift was tested. One of the four-blade configuration problems is that you lose reliability when the blades overlap during rotation, and therefore you need to either lengthen the fuselage to prevent them from overlapping or shorten the blades. But at the same time, such a scheme can not be excluded in the future. "

engine change

According to Mr. Rott, Boeing began research to replace the Honeywell T55 twin turbine engines with a new and more powerful power plant, although this requirement has not yet been defined. “We have been thinking a lot about the new engines, but so far there is no movement in this direction. Of course, if you are going to fly up to the 2060 of the year, and you also want to install four blades, this almost accurately determines the need for a new engine, but for now we are thinking. The current engine is fantastic and exactly suitable for all the tasks performed by the helicopter today, but if you are thinking about increasing the load capacity in the future, then you need a larger engine, most likely already somewhere in 2020's. A stronger transmission and powertrain is one of the components of the Block 2 retrofit, after which we can talk about installing a more powerful engine. ”

In addition to increasing the payload of the Chinook helicopter, Boeing also considered the possibility of increasing the cross section of the main cabin to transport ever-increasing military cargo. However, as with any other refinement, it indirectly affects other characteristics of the helicopter.

“In order to include military cargo of large sizes, it was planned to increase the cross-section of the hull. But immediately there is a problem with the transportation of the Chinook helicopter in the C-17 transport aircraft, in this case it is necessary to expand its cargo compartment accordingly. Another problem is the skew air flow around the fuselage during a helicopter hover, since a wider fuselage reduces lift, ”Rott said. There is also a problem with the "plump" options Chinook. Of course, the increased fuel tanks allow you to have more fuel, but the disadvantage here is again in the skew of the air flow and the greater mass that needs to be lifted into the air. "We will offer customers increased fuel tanks only upon their request, and not as a base case."


Unloading a Chinook helicopter from a C-17 transport plane

In general, all Boeing’s thinking about possible improvements to the existing Chinook helicopter is what promising technologies may be available and how much they may cost. “We do not want to offer something that the army cannot afford, but at the same time we want the army to receive things that it can fully afford. It's all about the art of the possible, ”concluded Rott.


Remaining in service for more than 50 years, Chinook is likely to remain in service for 50 years, which will make it the world's first "centenary" helicopter

Technical characteristics of the transport Chinook helicopter

Cruise speed: 291 km / h
Range: 370 km
Service ceiling: 6000 m
Maximum total weight: 22680 kg

Prospects

Of all the types of helicopters in service with the American army, Chinook was least affected by recently announced restructuring plans, according to which Bell OH-58 Kiowa helicopters are being decommissioned, Boeing AH-64 Apache is being transferred from the National Guard to the current army, and part of the Sikorsky army vehicles UH-60 Black Hawk transferred to the National Guard. This means that the US Army knows exactly what it has and what it wants from its Chinook helicopters.

In addition to the United States, the Chinook helicopter was sold to 17 countries. All operators with the exception of Argentina (for financial reasons) are still operating these helicopters.

As for further potential short-term and medium-term needs for heavy transport helicopters Chinook, then experts predict a portfolio of current or new orders up to 2024 of the year could be 915 machines with a total value of 42 billion dollars.

      The most interesting thing is that Western media are vying with each other about the old Russian technology.
      And it would be worth taking a look at the age of their own Chinook or the same Abrams and F-16 ....)))

      Chinook first flight September 1961 the Yak 24 helicopter the first flight in July 1952, it simply ceased to meet the requirements of the military, and in 1957 the Mi 6 appeared. So, to say that it was not successful was somehow incorrect (it would simply have been supplanted by a better one).

      The Yak-24 is rather a prototype of a helicopter: a wooden body, piston engines. Probably the closest thing to the Chinook is the B-24 Mile. Indeed, the States have managed to create a good design. It is strange that the USSR did not try to create their own version of "Chinook".

        the fact of the matter is that the longitudinal arrangement of the screws has many disadvantages and therefore did not further develop this scheme, and the Americans can be said to repeat later
        9 years, only at a different technical level (gas turbine engines have already appeared instead of piston ones).

      This is probably why there were hundreds of them in the USSR Armed Forces and on youtube there is a video of exercises where, contrary to wikipedia, there are clearly over 40 of them in the frame (English already writes that 40-100 pieces were released.)

      Mi-6, too, was not allowed to play around for a long time.

      Have you tried peeking at wikpedia?

      Boeing CH-47 Chinook flew at 1961g, nine years later. The Yak-24 allegedly did not please the military, because it was too big and therefore the moshli was a big loss in the paratroopers - as if he could not carry goods

        In the USSR, in general, everything was built in a large series. At that time, the Yak-24, in principle, simply had no competitors due to the "wagon" type cargo compartment. This does not mean that the design was successful. The giant Mi-6s at that level of automation of piloting and navigation, in general, should not have been built in large quantities. Again, in the presence of the Mi-26 (the "advanced" vehicle of the line launched by the Mi-6), only the ardent interest of the military in the "wagon" -type cargo compartment can explain the appearance of the B-24, which did not go into series. So the Chinook, despite the noted "shortcomings", is considered by the customers as a very effective complex.
        Another thing is that the ship can be large, and can be white. This is difficult for some to understand. In addition, we all know where the birthplace of the largest elephants was located. At this point, it is difficult to talk in the same plane.
        Mi-8 and Mi-6 do not directly compete with the CH-47.

          Therefore, does it mean that it was unsuccessful? Perhaps that is why then it was necessary to build the Mi-8 even more massively instead of the Mi-6 and Yak-24
          Mi-26 does not apply to Mi-6.
          You know, but you are mistaken even about that - they don't like Chinook, they like CH-46, the "carriage" can be attached to any helicopter, the point is in its size. The F-35 was released ... in a large series, and the bad H-4 is in the museum.

      Afghanistan 2009. The Mi-26 took out the damaged Chinook on an external sling. Having flown about 110 km with the Chinook, the heavy Mi dropped its cargo at the American helicopter base in the Kandahar region. The car was lightened as much as possible, the engines were removed. It was on the occasion of the removal of this "Chinook" that Barack Obama expressed his gratitude to our helicopter pilots.

      In 1988, the US Army CH-47 participated in the evacuation of the Mi-24 helicopter thrown by the Libyan army in the desert during the war in Chad. With a helicopter on an external suspension, Chinook overcame a distance of 900 km at night in a sandstorm, having spent one refueling in the air

    The moral here is to create a good face in a bad game! In fact, Chinook is not so good as he is painted. The trick is that there is nothing to replace it with! Like Hercules, like a black hawk! And to equip the old car with new nishtyak, far from creating a new one! Moreover, from an engineering point of view, the longitudinal scheme is very flawed!
    Well, the Americans could not create a machine such as Mi-6. Therefore, they have, they have!

      Moreover, from an engineering point of view, the longitudinal scheme is very flawed!

      Each scheme has its own advantages and disadvantages, but it is not correct to call it "flawed".
      The longitudinal scheme consists of two horizontal screws located one after another and rotating in different directions. The rear screw is raised above the front screw to reduce the negative impact of the air stream from the front screw. This scheme is mainly used in heavy helicopters.
      The positive aspects of this helicopter scheme are:
      large volume of cargo space. Longitudinal helicopters are sometimes called "flying carriages".
      large allowable range of service centers. The ability to use almost the entire volume of cargo space without loss of controllability
      The disadvantages of the longitudinal scheme of the helicopter include:
      the appearance of significant vibrations in some flight modes. This effect was especially pronounced on early helicopter models.
      some deterioration in the efficiency of the rear rotor. To solve this problem, the rear screw is located higher than the front
      some asymmetry of stability and controllability in the traveling relation
      complex transmission.

    I wanted to say something like that. Which can easily meet the centenary, since the Americans can’t create anything better. In North Korea, for example, there is a chance to celebrate the centennial of our Su-7. But, not from a good life and not because this plane is so outstanding. Also in the states. The founding fathers of the American helicopter industry, immigrants from Russia, died, and they froze. A longitudinal scheme, of course, is not ice. Extra losses in the transmission, less efficiency of the screws.

      If you mean Sikorsky, then he died back in 1972. The last helicopter built by Sikorsky before retiring was the S-58. Serial production of the S-58 at Sikorsky Aircraft was conducted from 1955 to 1963. So you are clearly exaggerating the role of immigrants from Russia in modern American helicopter engineering. hi

        I had this about 30 years ago. Spanish copy of the nasty
        quality. I bought an old one on the cheap, captivated by the formidable view.
        Every two or three shots are a misfire. And jumped in my weak hands, like a bunny.
        But the roar!
        The stone-throwing Arabs (the first intifada) scattered instantly, and I didn’t
        fortunately did not kill. fellow

    Here's a cool photo: Chinook picks up the F-15,
    which is larger in size!

            This is an unflagged crane ... the congress was tired of cutting and gagging. They Chinook then barely mastered.

    Not a single western-made helicopter can't take on board as much cargo as Chinook can take ...

    CH-53E Super Stellen - 13,6t, and 14,5t on external suspension (for example, LAV-25 8x8).

      Apparently, a little more than 12 tons of Chinook - still more!
      Thanks to its relatively low cost of maintenance and operation, flight resistance to high altitude conditions.

    Not every aircraft has significant design reserves, allowing you to operate the machine for a long period of time. In this sense. "Chinook" is an outstanding machine. The point here is not at all that "the Americans can’t create anything better," because with the death of the founding fathers of American helicopter engineering, immigrants from Russia, aviation science "froze", as some commentators write, but rather in economic feasibility. Why reinvent the wheel, if you can improve the design of its individual elements.
    The “long-livers” also include the Soviet Mi-8 helicopter. Today, not America, but rather Russia needs to think about how its aviation science would not die. So far, there are no reliable Russian-made aircraft engines, not only jet and turboprops, but even economical piston engines for small aircraft. A significant part of the cargo fleet is made up of vehicles of the An family, which are not produced in the country. New aircraft factories are not being built; problems with training personnel are growing. You can talk about “loss in transmission”, “propeller efficiency” as much as you like, but the fact remains that in matters of civil, transport and small aviation, we are still “lagging behind” the West and the USA. They made their own Superjet and MS-21, but units from Russian airlines buy them, or don’t buy them at all. The American Osprey tiltrotor is still flying, in the USSR they used to say about the absurdity of such a design, now in Russia they are trying to create something like that. Such “shyness” does not impress either amateur schoolchildren or specialists.

    mi- 8 and 17 I think they will not yield in popularity. and the load capacity of our mi - 26 will be higher and the scheme is better - not longitudinal. so ode to sing - we won’t begin to chinook.

      Singing odes to him is not necessary. But there is no reason to scold the last words either.
      Normal, run-in machine with a design licked over decades.
      You can argue as much as you like about the fundamental advantages and disadvantages of a longitudinal construction. But its implementation is quite successful. Which proves the attitude to the machine of its main operators.

    While many modern standard helicopters have moved from main rotors with two or three blades to rotors with four or five blades to increase speed and aerodynamic lift, Chinook stopped on its configuration of two main rotors on three blades. Rott explained: "The six blades of the two rotors, given their current length and width, create excellent lifting force."
    Well, like this. And after 50 years you can put 5 blades. This is a good way to leave in your pocket a stock of upgrades to milk the Pentagon forever. Moreover, on fairly minor modifications.

    And it seems to me that Chinook will survive until 2060 because the budget for the defense industry in the United States has already been allocated, and there are no more budgets for transport helicopters.

    Not about that! Beautiful cars will always remain as such ... Great idea and execution of the same ... The age of "couple" is behind, but no one dares to say a bad word about Ovechki. Despite ... An excellent car turned out and let it fly for another 200 years, while it is in demand.

    Helicopter of the American aircraft designer of Polish origin Frank PJASECKI HRP Rescuer "flying banana", a pioneer of longitudinal helicopters. The first flight in 1945, was adopted by the US Army, serially produced in 1947 - 1949, about 30 built. Frank Pyasecki founded the Piasecky helicopter, but left in 1955 due to disagreements with the board of directors. And in 1960 this company (which had become "Vertol aircraft" by that time) was bought by "Boeing". Pyasetski succeeded in eliminating the main scourge of the longitudinal scheme - vibration in his designs and at times using the main advantage - the increased volume of the cargo compartment. Unfortunately, the Yak-24 could not completely eliminate vibration, although they achieved a significant reduction in it, and the further development of longitudinal helicopters in the USSR stalled.

      Slightly shortening the blades eliminated everything. Is there really a helicopter that doesn't shake at all?

    As I read in the Auto Review, a little over a century ago, Rolls-Royce produced more than 100 cars and more than 000 percent of them are still underway. So, not everything is bad for an Indian! wink
