AIRCRAFT WITH OPTIMISED PAYLOAD SPACE AND METHOD OF OPTIMISING AIRCRAFT PAYLOAD SPACE Russian patent published in 2012 - IPC B64C1/00 B64D33/00 B64G1/40 

FIELD: transport.

SUBSTANCE: invention relates to aircraft with power plant and payload inner space, particularly, to aircraft or spaceship. Aircraft comprises fuselage 2 with cabin to accommodate people and/or cargo, and power plant. The latter comprises at least one convertible tank 6 and/or combustion chamber in the case of spaceship. Tank 6 may represent soft fuel reservoir 29 arranged in container 31 and formed by tight membrane 30. Sufficiently strong bulkhead 10 is arranged between cabin 4 and tank 6. With reservoir filled with fuel, access to tank 6 is prohibited by hatch cover 18. With reservoir 29 emptied, for example, via valves 32, supporting forces cease to act on said cover for it to be removed together with membrane 30. Container 31 makes a continuation of cabin 4. Spaceship may use liquid or solid propellant power plant with appropriate combustion chamber (not shown). Hatch similar to hatch 18 is arranged in chamber head on cabin side to allow access to combustion chamber and fuel combustion therein. Note here that combustion chamber neck (critical section) is stopped by plug.

EFFECT: increased payload space.
