Problems solved by technology
[0002] There are three ways for the existing aircraft to assist take-off: ski-jump take-off, catapult take-off, and vertical take-off. The lift and the thrust of the engine are used to take off. Due to the limitation of the length of the runway, the aircraft cannot take off with a full load, which limits the performance of the aircraft; the ejection take-off method mainly relies on steam ejection and electromagnetic ejection. The steam ejection device is large in size, takes up space, and consumes a lot of fresh water. resources, and a serious waste of power; the existing vertical take-off method requires the aircraft to have a vertical take-off and landing function, and the operation is complicated, but it cannot take off with a full load, which limits the performance of the aircraft
[0003] The aircraft take-off methods in the prior art cannot achieve no runway run-up, no steam assist, no electric power assist, and full-load take-off at the same time, which seriously limits the performance of the aircraft.

Embodiment Construction
[0017] Such as Figure 1-3 Shown, a kind of aircraft take-off device 2 is made of fixed shaft 4, annular body 5, rotating arm, aircraft support platform 7, aircraft fixed clamping plate 8, engine 9, hydraulic telescopic rod 10, rotating arm support rod 11, hydraulic lifting platform 12. It is composed of a holding ring 13 and an oil tank 14. The fixed shaft 4 is fixed on the ground 1 and runs through the ring body 5. The ring body 5 is an inverted "convex" stepped ring structure and is sleeved on the fixed shaft 4. The fixed shaft 4 is movably connected with the ring body 5 through ball bearings. One side of the annular body 5 is fixedly connected with the rotating arm 6, and the other side is fixedly equipped with a fuel tank 14. The other end of the rotating arm 6 is movably connected with the aircraft support platform 7 through a rotating shaft, and the rotating arm support rod 11 is fixed on the bottom of the rotating arm 6. An engine 9 is installed at the center of the b...

The invention discloses a device for airplane take-off. The device mainly consists of a fixed shaft, a ring-shaped body, a rotary arm, an airplane supporting platform, an airplane fixed clamping plate, an engine, a hydraulic telescopic pole, a rotary arm supporting rod, a hydraulic lifting table, a hoop and an oil tank, wherein the fixed shaft is fixedly connected to ground; one end of the rotaryarm is fixedly connected to the ring-shaped body, and the other end of the rotary arm is connected to the airplane supporting platform; the engine shaft is perpendicular to the rotary arm; the engineis started, so that the airplane supporting platform carries the airplane to perform circular motion; the hydraulic telescopic pole performs telescopic control according to centrifugal force changes of the airplane, so that airplane acceleration is ensured to be safe; while take-off speed is achieved, the airplane fixed clamping plate is opened and the airplane flies away from the airplane supporting platform, so that take-off operation is accomplished, and therefore, take-off, without run-up on a track, of the airplane is realized.
Description
technical field [0001] This application relates to the technical field of UAV design and manufacture, in particular to a heavy-duty UAV with vertical take-off and landing variable wing cruise.
