Patent ID: 7707820

Claim:
A control and/or drive device for a flying body for ejecting a hot gas stream of a combusted fuel combination of at least a first and second component, said device comprising: a first hollow chamber body structured and arranged to contain the first component; a second hollow chamber body structured and arranged to contain a second component; a controllable fuel valve arranged between said first hollow chamber body and said second hollow chamber body to control a feed of the first component to said second hollow chamber body; a plurality of outlets structured and arranged to eject respective hot gas streams for influencing a flight path of the flying body; said second hollow chamber body being formed as a combustion chamber for combusting the at least first and second components within said second hollow chamber body to generate said respective hot gas streams; a storage vessel arranged adjacent said combustion chamber; a membrane or piston arranged to separate said storage vessel and said combustion chamber; said plurality of outlets being connected to said second hollow chamber body, wherein said outlet device includes a plurality of hot gas valves, which are switchable to control a respective gas stream between said second hollow chamber body and a respective expansion nozzle; and an electrically controllable hydraulic valve, wherein at least one of said at least one expansion nozzles comprises a transverse thrust nozzle, and said at least one of said plurality of hot gas valves is controlled by said electrically controllable hydraulic valve and is connected to said transverse thrust nozzle for ejecting the gas stream, wherein the piston or membrane is structured and arranged to generate hydraulic pressure for actuating said hydraulic valve; wherein said piston or membrane is arranged so that a pressure generated by combustion in said second hollow chamber body acts on said piston or said membrane, which then releases a resultant force to said hydraulic fluid.
