AIRCRAFT Russian patent published in 2012 - IPC B64G1/40 

FIELD: transport.

SUBSTANCE: invention relates to aerospace engineering and may be used in flight in open space and in atmosphere. Aircraft has fuselage 1, damper 5 with control unit 2 arranged in said fuselage, jet engines 6, 7, exhaust nozzle with exhaust tube 3 bent downward, and cylinder 12 with exhaust tubes 8, 9. Cylinder houses cylinder 10 with jet engines 11 and end bent rods 13, 14. The latter interact with safety thrusts 15, 16 to prevent collision between piston and fuselage. First, aircraft is accelerated by jet engines 6, 7 and 11. Said rod bent parts adjoin thrusts 15, 16. Fuel is continuously fed into damper 5 to gases to be ignited therein, said gases effusing through nozzle 4 and bent tube 3. Define flight height reached, continuous fuel feed in damper 5 terminated to start proportioned feed (pulsed mode of combustion and gas efflux). Piston 10 starts motion inside cylinder 12. Piston 10 and fuselage 1 are pushed apart. After damping, gases escape via exhaust pipes 8, 9. Jet engine operation makes piston displace toward damper 5. With piston approaching the damper, gases are ignited again for cycle to repeat. Note here that during piston travel next fuel portion is fed into damper.

EFFECT: higher aircraft reliability.
