Plywood logistics: disposable transport UAVs from Logistic Gliders


UAV LG-2K in flight


Currently, the U.S. forces use a wide range of different means to supply remote or isolated units. In the near future, existing systems can be supplemented by promising unmanned gliders developed by Logistic Gliders Inc.

Supply problems


In certain situations, supplying troops by air can be difficult. An aerodrome for a transport aircraft may not be in place, and helicopters are vulnerable to enemy air defenses. The same goes for military transport aviationdropping parachute platforms.

In this regard, the US Marine Corps and the DARPA agency launched the TACAD (Tactical Air Delivery - Tactical Air Delivery) research program, which aims to create new air transport for delivering small cargoes with minimal risk.


Drone circuit

Given the level of technology development, customers proposed the development of specialized transport UAVs of simplified design. Such a product should carry a load of hundreds of kilograms, be launched by dropping from the regular aircraft KMP and cover tens of miles through the air. Reuse is optional. The cost of the drone is limited to 11 thousand dollars. Ammunition, provisions, medicines, etc. are considered as potential loads.

One of the participants in the program is the Californian company Logistic Gliders. Back in 2018, she patented the original design of an unmanned glider, and so far has put two types of such equipment with different characteristics to testing.

Two gliders


Logistic Gliders company offers the customer two UAV options under the names LG-1K and LG-2K. The first project was developed with the participation of specialists from the Marine Corps Warfighting Laboratory, the second was created in collaboration with DARPA. Moreover, both solutions are based on the same solutions.


Glider details

Both projects propose the construction of a non-motorized aircraft with a normal aerodynamic design. To reduce the cost of production, most of the parts are made of plywood. For the same purpose, the glider has rough contours. The main part of the fuselage is given under the cargo compartment, and the minimum necessary controls are located in the tail.

The fuselage of the LG-1K and LG-2G gliders is made in the form of a plywood box of a given size. The flat nose fairing acts as a shock absorber when landing. In the central part of the fuselage, a straight wing of great elongation, which is laid out in flight, is attached. During carrier transportation, the planes are located along the fuselage, and when reset, a special mechanism translates them into working position. The tapering tail carries plumage with a stabilizer, keel and a pair of washers. The UAV can be equipped with a landing parachute, but it is located in the cargo compartment and reduces available volumes.

For the delivery of goods to their destination, a fairly simple control system based on available components is responsible. It includes satellite navigation and an autopilot that controls the ailerons and tail surfaces. There are also remote controls that allow the operator to navigate. Telemetry and video from the bow camera are transmitted to the remote control.


Glider in transport position in carrier cargo compartment

UAV type LG-1K has a length of 3,2 m with a wingspan of 7,1 m. 0,9 kg of payload is placed inside the cargo compartment with a total volume of less than 320 cubic meters. The LG-2K glider is noticeably larger and heavier. Its length reaches 3,9 m, wing span - 8,4 m. 1,2 kg of load are transported in a compartment with a volume of 725 cubic meters. Own mass of a larger apparatus - only 181 kg. During planning, both samples have a speed of not more than 280 km / h. The maximum planning range is 70 miles. Aerodynamic quality - 12.

According to the customer’s conditions, new types of UAVs should be used with a wide range of transport planes, helicopters and tiltrotors KMP and the US Air Force. Depending on the type and characteristics of the carrier, the glider is transported in the cargo compartment or on an external sling.

The way to use gliders is quite simple. The carrier enters the specified area and dumps the UAV in the transport position. After the reset, the glider opens its wings and begins an independent flight to the specified coordinates. There, the drone performs a horizontal landing or releases a landing parachute. After that, the “addressees” can disassemble the glider and take out the delivered cargo. Repeated use is not provided.


Outboard transport

It is claimed that the LG-1K and LG-2K have a number of important advantages. They are simple and cheap to manufacture, and also fully cope with their tasks. Gliders are compatible with several carriers and are capable of transporting a variety of goods that meet the restrictions of the cargo bay. They also show fairly high flight characteristics and represent an extremely difficult target for enemy air defense.

Real results


The TACAD program has already reached prototype testing, and Logistic Gliders' developments have demonstrated some of their capabilities. The first flight tests took place in January last year. Then we conducted several new tests.

In January trials, 12 UAVs of the LG-1K type were used. Half of the gliders started from the external suspension of the aircraft, the rest were dumped by transport aircraft through the aft ramp. 7 flights performed with remote control; others were carried out offline. The first tests did not provide for flights at maximum range, because of which their total duration did not exceed 55 minutes. Nevertheless, it was possible to confirm all the basic characteristics and capabilities of gliders.


Aircraft reset

Until the end of the year, the ILC, DARPA and Logistic Gliders conducted several more tests using different platforms and in different conditions. In December, it was reported that since the start of the tests, 18 flights have been completed with a total duration of 96 minutes. They used various media, up to the military transport aircraft C-130. 10 flights were performed offline with a demonstration of the required accuracy of launch and landing.

New tests took place in mid-January 2020. Gliders were again discharged from aircraft and helicopters of various types. It is likely that UAVs were improved before these tests, taking into account the experience of previous events.

Logistics and Economics


According to well-known data, the TACAD program is still at the stage of flight testing and refinement of equipment. The real prospects of the presented samples from Logistic Gliders have not yet been determined. Nevertheless, the basic capabilities of such a technique, its scope, advantages and disadvantages are already clear.


LG-2K in flight. Visible wing and strut design

First of all, the approach to the design of special UAVs is interesting. Fulfilling the customer's requirements in terms of cost, the development company used the simplest and cheapest materials and components. This made it possible to obtain the necessary characteristics and an acceptable resource.

Gliders combine good flight characteristics, acceptable carrying capacity and successful controls with two modes of operation. The flight control method, stand-alone or according to operator’s commands, can be selected depending on various factors.

The developer’s statements about the high stability of the UAV to the enemy’s air defense systems are interesting. A predominantly small-sized wooden glider is difficult to notice and hit. In addition, it is unlikely to become a priority target for anti-aircraft gunners, although it will reduce the risks for its carrier.

For special tasks


In general, Logistic Gliders managed to create an interesting and successful specialized model of equipment for solving specific transportation problems. Tests of the two types of UAV gliders are still ongoing, and the design is being improved. However, the main features of the technology have already been identified and are unlikely to change in the future.


UAV after horizontal landing

It is to be expected that the ILC, the Air Force and DARPA will show greater interest in new models and, possibly, even bring them to adoption. As a result, the US Army will receive a fundamentally new means of logistics that can occupy a characteristic and important niche, reducing risks for other vehicles.

However, drones of new types should not count on a large series and wide distribution. Situations in which they are necessary do not occur too often - and in other conditions, well-developed and familiar forms of air transport can be used. However, this is the case when the presence of a highly specialized tool is better than its absence.

        An interesting concept is a single-use UAV container.
        Although, in my opinion, dropping a container by parachute is easier and cheaper.
        Moreover, modern parachutes have learned to make planners. It remains only to add an autopilot. Although on the battlefield, when you need to transfer a box with shells to a specific trench, this UAV is still useful.

          But not so far and aiming.
          And not the fact that a controlled parachute / paraglider will be cheaper than the plywood parcel of the postman Pechkin, even with wings, navigation, an autopilot and an operator’s camera.

            In addition, you can make the electronics block easily removable and at least slightly protected, and reuse, as if the multiplicity will be higher than that of parachutes.

          With difficulty I tried to imagine this "difficult point". So, there is no suppressed air defense (let only the Shell-s remain at a minimum). There is no way around it - that means our "difficult point" in the ring or behind the front line at a distance of no more than 112-20 = 92 km. Is this a partisan detachment? Okay, let's say in the USA there is Kovpak with a bunch of scouts. Without heavy weapons, equipment ... Well, let them live. In the winter, our wolves also need something in the forest.
          This idea is just right for supplying the barmalei in situations similar to Idlib. But this is a unique situation, which appeared due to the indecision of politicians, and not the military. Wonderful wars is a wonderful technique.

            The drug industry is also likely to check out such a thing. In general, there are buyers.

    Although, for a fan plan without a pilot, this is probably not critical.

    There is only one question - the maximum flight length? It doesn’t turn out that the parcel was thrown away, and the whole Hercules covered the air defense?

          I do not argue. The bourgeois have such plans, I will quote:
          Today, the US Army and Marine Corps use transport aircraft to deliver cargo to ground units. These loads are dropped from aircraft by parachute. This delivery system has been tested for decades, but has already ceased to meet modern realities.
          The fact is that during the fighting, the troops of the fighters are far removed from each other, and parachute systems cannot plan a considerable distance. It can be very expensive and dangerous to organize targeted flying around a transport aircraft.
          A new delivery method was proposed by Logistic Gliders Inc. ...

          PS Maybe this case will not take root ...

    It is interesting why unmanned cargo delivery systems strive to make it out of plywood. After all, delivery can be carried out using a simplified unmanned cargo paraglider-machine: it will cost about the same, but after landing it is guaranteed not to break into chips, easily assembled on the ground, transported and reused, easily repaired by a darn on a sewing machine.

        The cargo box can be taken on the cargo hook of the automatic paraglider even when loading, the paraglider itself is separate, in its own "box". And to throw out everything automatically with the usual rubber-fabric conveyor for transporting goods (as in supermarkets).

      In a managed version, it is probably easier, cheaper and more practical than an article made of plywood.
      A paraglider (or parachute - wing) is lightweight, but not at all simple and has serious limitations on weather conditions.

        A paraglider and even such a weight will be much more expensive. Plus the ability to fold. And unfolding also at that speed is still that task. Well, in general, a paraglider maintain such a speed ... In short, the difference is immediately visible to paragliders and gliders, but it is difficult to see it when flying.

          The Americans have already successfully tested a controlled and reused automatic machine wing (1990s: JPADS program (Joint Precision Airdrop Systems, Russian - “Interspecific means of precision landing”)). The actual cost of delivery was about $ 60 / kg, the maximum mass of cargo in the line of parachutes was 19 tons, and they almost began to design a parachute for 28 tons. A box with wings - on competitive terms $ 15. But in practice there will be slightly more. But nevertheless, since the costs do not differ by orders of magnitude, uncontrolled and controlled parachutes continue to be used and now and from time to time they try to refine them.

              Yes, why do all this then? If plywood is available in any corner of the globe. A set of control electronics and drives with accumulators and power elements for assembling such a UAV will fit in a small drawer. They brought plywood sawn. Twisted on the screws in place. Or collected from the go whale. They threw them for a certain number of kilometers and voila crashed so do not worry the plywood by the shaft, the control system is not more expensive than for a quadrocopter.
              Why all these rope cables with incomprehensible control and an unknown result!
              Just the key to success. And here it is simple and cheap.

                Fabrics are produced in very large quantities in the world - there are so many of them that they are quietly spent on disposable cargo parachutes. The estimated cost of ASG LCADS-LV is $ 1260, LCADS-HV is $ 495, and CDS type CDS is $ 3815. Both wood and fabric have their intrinsic advantages.

                  Of course. Only plywood is everywhere and the fabric needs to be bounced. Well, with a cherry on the cake, there is a cutter machine for sewing and qualifying a seamstress. And I cut the plywood with any hacksaw and voila.

                    Only plywood is everywhere and the fabric needs to be bounced.

                    Plywood is made in a plywood factory and does not grow in the forest. This imported material, like fabric, tools - no noticeable difference from fabrics in logistics and accessibility. The fabric from the manufacturer is driven rolled in wagons - look for the type “fabric roll 5 tons” or even better “grab the loader for fabric rolls” - you will see how the fabrics look not in a smoked retail store or boutique but in the wild, to tell.

    Before World War II, airborne cargo gliders were in Germany and the USSR. And how did this affect at least one large-scale operation?

    I mean, how did it influence ?!

    10.05.1940/XNUMX/XNUMX, Belgium, for example. Or the rescue of Mussolini.

    The score for the downing of such prodigies flying to Khmeimim, already goes to hundreds. So on the topic of sustainability ... excuse the complete garbage, except from the point of view of American means of object-based air defense. winked But as an option for a cheap means of delivery, this is quite an argument.

    what is the advantage over parachute systems

    About LG-1000 they wrote:
    It is made entirely of wood and its cost is only 600 dollars, which is 1/3 of the cost of a modern parachute system.

    Already saving. Plus he drives to the destination.

    Before World War II, airborne cargo gliders were in Germany and the USSR. And how did this affect at least one large-scale operation?

    The American airborne landing in Normandy became the first US military operation during Operation Overlord (the invasion of Norman forces by the anti-Hitler coalition during World War II) on Day 6 June 1944, 13.100. About 82 paratroopers from the American 101nd and 6st airborne divisions landed on the night of June 3.937th. During the day, 2 glider soldiers also landed [XNUMX]. As the beginning of Operation Neptune (the assault part of Operation Overlord), American parachute divisions landed on the continent, performing two parachute and six glider missions hi

      So after all, the glider was controlled by pilots, balancing the center of gravity was carried out on the ground. And here is just a container

    You do not need to be bitten by Bath to predict that the final cost of a unit from the voiced one will differ ten times, and upwards. And after it turns out that to bring down this plywood, a hundred-dollar drone with AliExpress a, to which a photocell was attached, and a cumulative charge will be enough. Well, they provided the simplest homing firmware. Speed ​​to catch up and burn to crap - enough for almost anyone.

    An extremely reasonable decision. Extremely cheap and simple, plywood also provides another non-obvious advantage: in severe cases, it is also a little extra fuel.

    Well, where does the characteristics of the airframe, just to your passage about how the use of gliders affected the results of operations, I gave an example. That's all. hi

    Great idea! Just a flying plywood box. Management from a pair of Chinese microcircuits, the price is scanty, the planning range is decent, you don’t have to climb into the enemy’s near-air defense zone.

    There is a suitcase without a handle, there is a handle, and now with plywood wings. A great way to support reconnaissance, cut off units, mountain outposts.
    One concern: otherwise, if it lands (lands) in the zone of the Barmalei, will it give them a gift for 700 kg of ammunition / ammunition / application / medication?
    The lock should be put with a code so that a suitcase spreads +30 meters around in chips, if the PIN code is incorrect).

    Add to this a small engine, chassis and stool, and instead of a control system, a dear oneself. Yet K = 12 is not so little, it would be quite possible to ride. )))

    Mdaaa ... it’s not in vain that “the new is the well-forgotten old ...”! Gliders were widely used in 2MB ... and, most often, as "disposable", although it was supposed, sometimes, they were "after" disassembled and delivered to the "base"! Interest in gliders led to the idea of ​​motor gliders ... (the motor glider took off with the help of a towing plane, and there ... "herself, herself ..."!) There was such a "crazy" idea in the project ... the glider took off " "with the help of, for example, a liquid-propellant rocket engine or turbojet engine; but, after climbing, the" block "with the engine (s) was parachuted and could be reused ... That's just" robot pilots "then did not have time to come up with ... all did, like children, the old fashioned way!

    Very interesting glider. The launch range of more than 100km allows you not to enter the affected area of ​​most anti-aircraft missiles. To dump vital cargoes in the environment. It can fly to the lighthouse.
