American high-speed helicopter SB1 Defiant dispersed faster than 100 knots

American high-speed helicopter SB1 Defiant dispersed faster than 100 knots

The promising multi-purpose high-speed helicopter SB> 1 Defiant, developed by a consortium of companies Sikorsky and Boeing, made its first flight at a speed of more than 100 knots (185 kilometers per hour). The tests took place at the airport of the American company Sikorsky in West Palm Beach (Florida). A video of these tests on his YouTube page was posted by Boeing.


As the developers explained, accelerating a helicopter to a speed of over 100 knots is one of the most important marks when testing the latest high-speed helicopters. At the next stage of testing, which took place on January 13, 2020, the helicopter not only accelerated faster than 100 knots, but also he performed a series of turns with a roll of 30 degrees. The tests are recognized as successful.

The creation of SB> 1 is carried out on a competitive basis as part of the US Army's helicopter development program of a new concept for creating a family of promising army vehicles aviation. The first prototype demonstrator built SB> 1 was shown on December 26, 2018.

According to the requirements of the US Army, the new helicopter must transport 12 fully equipped infantrymen with a cruising speed of at least 230 nodes (about 428 km / h) to a distance of at least 229 nautical miles (424 km). The program provides for the creation of five types of new helicopters or vertical take-off and landing aircraft to replace the entire fleet of US Army helicopters (OH-58, AH-64, UH-60, CH-47), starting around 2030-2035.


The SB> 1 helicopter uses a new carrier circuit developed by Sikorsky, combining coaxial propellers of opposite rotation with a tail pusher propeller driven from the rotor gearbox. This scheme was worked out on the demonstrator of the 2015-ton S-5 Raider helicopter tested since May of the 97, which has a “passport” maximum speed of 444 km / h and cruising speed - 407 km / h.

The maximum take-off weight of SB> 1 is declared at 32000 pounds (14515 kg), capacity - up to 18 people. The helicopter is equipped with modified Honeywell T55 turboshaft engines with a take-off power of approximately 4000 hp, cruising speed - 460 km / h.

The SB> 1 Sikorsky and Boeing competitor in the replacement program of the US Army helicopter fleet is the V-280 Valor convertoplane of the Bell and Lockheed Martin consortium, the prototype of which passes flight tests from December 18 of 2017.

    This one can "knock out" the tiltrotor from the race ... If they can cope with the aerodynamics of the rotors at speeds around 500 km / h. And why our “Kamovtsy” do not develop such? Really not needed?

      It’s like, what’s going on in the world? What, now the super-duper "Osprey" in the scrap? So much money was spent on an expensive toy. lol All these attempts to combine the “soft with the warm”, instead of functionality, lead only to a significant complication and cost of the project, with a dubious future. In terms of theoretical research, I agree, the project is interesting, but the idea is far from new.

      And knock out. If not he, then another, according to the same scheme. Sailing - evil.
      If they can cope with the aerodynamics of the rotors at speeds around 500 km / h.

      Well, they will not be up to 500 for objective reasons. 400 cruising will be enough - this is a one and a half increase in speed compared to the existing fleet and a sharp increase in combat potential.
      And why are our “Kamovtsy” not developing this? Really not needed?

      In fact, this is exactly what Kamovtsy are developing - also according to this scheme. Moreover, according to the available pictures - more practical. But you have to hurry.

    Interesting. Everyone is now trying to create high-speed helicopters that are only 150-200 km / h superior to existing helicopters, but 500-800 km / h lower than the speeds of modern attack aircraft. Why such hard work, can anyone explain? Personally, I don’t understand, at least blame me.

          It’s not worth it to convince you. But I’ll try to explain. The helicopter can take off and land on unprepared sites and does not require an extended runway. Attack aircraft cannot do this. But helicopters have lower speeds than planes. Therefore, increasing the speed for helicopters is an important task. But it rests on the aerodynamics of the rotors. Easier - the speed for such a scheme can not be increased indefinitely. By the way, for the same reason, tiltrotors can compete with helicopters. Convertibles can fly faster despite a more complex scheme.

      A ground attack aircraft needs an equipped airfield. You can’t put modern cars on the field or in the clearing, and public roads have not been designed for this for a long time. Accordingly, in a number of situations when it is necessary to carry out combat missions, but there are no ways to ensure the availability and safety of the airfield, helicopters are useful. These are the above-mentioned operations of evacuating and dropping groups behind enemy lines, and direct fire support of troops on the front lines, in difficult terrain, especially if the enemy has long-range air defense systems that will not allow attack aircraft to fly quietly and efficiently in a straight line at high altitude 200 -400 km from the airfield jump. Do not forget also about the cost of deploying infrastructure for aircraft in case of offensive or expeditionary operations like in Syria. A helicopter can land on any site, is much less sensitive to weather conditions, can make its way to the target using terrain, especially in the mountains, which makes it possible to operate even in the enemy’s air defense zone ... All this together makes helicopters on the battlefield extremely useful in a number of situations. And why be surprised that designers are trying to increase their speed characteristics? This will reduce the reaction time to the attack, the flight time, if necessary, to provide support or fire for the enemy gathered in a heap, will allow more active maneuvering, will give some chances in maneuvering combat with enemy helicopters or light attack aircraft ... And that for 100-200 km / h - so it is necessary to rejoice at this. There are very serious technical difficulties. The very layout of a flying machine with a rotor is not particularly stable at high speeds, and the drag at the slightest tilt is growing very quickly ...

    And his prospects are very good, much better than the V-280 Valor - which is most likely a dead end.

        I agree with you. At the moment, aviation has reached its ceiling. For further development, new breakthrough technologies are needed. But they are not. A revolution in technology has not yet been foreseen, and all forces have been thrown at "digitalization" and the licking of the existing. Therefore, you have to "drag the lifting screw."

        The propeller creates lift, and with sufficient adaptability it approaches the wings.
        Do not forget that the main purpose of the helicopter is hovering. Speed ​​is needed only to minimize the time it takes to deliver the helicopter to the target, so that it has as much time as possible for its main work - freezing, which increases its efficiency.
        Can the V-280 Valor, by hovering, be compared to a helicopter? Also, the V-280 Valor is not able to compete with the aircraft in terms of speed and economy of flight. Something getting into the millet.

    He lacks wings. With them, when speed is reached, when aerodynamic forces begin to act on the wings, it would be possible to reduce the power on the main rotor, and thereby increase the flight range and reduce noise. IMHO.
    Again, points for the suspension of weapons and sighting systems or defense, to improve and facilitate handling at high speeds, so to speak "in the plane." Probably other "buns" will come out, in my amateurish opinion. what fellow repeat

        Heavy helicopters.
        They fly at speeds of about 200 km / h. At this speed, the wings, even if they are, are practically unnecessary due to the low lifting force and, in fact, are overweight.
        Another thing when planning a speed of about 500 km / h. There it is possible to expect greater returns from them.

    Interesting ... How did this mattress head come to Kamov's scheme? Previously, they only cherished it, sculpted all kinds of “chinooks” and strange products with intersecting screws, and then all of a sudden ... Moreover, the scheme, as always, will be declared an “American invention”.
    And the technical question: If they so carefully “licked” the rotor system, and the entire fuselage, then why is the landing gear not retractable? In appearance - ordinary struts with hydraulic shock absorbers. Or will a new retractable chassis be developed for the series? And what about the mass (harvesting drives, chassis compartments, sashes of these drive compartments)?

      Interesting ... How did this mattress head come to Kamov's scheme? Previously, they only cherished her ...

      The coaxial pattern has many pitfalls. During the development of the Ka-27, Kamovtsy faced a number of problems, the solution of which required an incredible effort and time from them. Therefore, the Ka-27 was born with a long delay.
      It was because of the problems that were considered insoluble that the Americans eschewed the coaxial scheme. However, after perestroika, they gained access to the Kamovtsev’s developments, which allowed them to go all the way to developing a coaxial circuit very smoothly.
      ... why does the gear not retract?

      SB1 Defiant is a milestone model, an intermediate, so to speak layout. The final stage is the FVL Medium, the development of which they will begin after 2020.

    This one can "knock out" the tiltrotor from the race ... If they can cope with the aerodynamics of the rotors at speeds around 500 km / h. And why our “Kamovtsy” do not develop such? Really not needed?
    And you read this article published in the military-industrial complex, then it may be clear hi https://www.vpk-news.ru/articles/54614

    Why such hard work, can anyone explain?

    Any attack aircraft requires GDP that is vulnerable. On the sea, you need an aircraft carrier that costs many billions of dollars. These can take off even from a barge. Speed ​​compared to helicopters is two. You compare, not with those aircraft. yes hi

    We are developing (were developing?) Ka-92 and Mi-X1. That's just the results are not visible. :(

    Now we have mastered the Kama scheme, but they put Karlson on the ass for speed. And we are still completing the Soviet legacy. And how will it end, what will we do?
