摘要： An aircraft of reduced drag adapted for buoyancy upon the thrust stream of its engines. The aircraft having a forwardly disposed base having a generally horizontally disposed upper surface, first and second platforms arranged in stepped relationship to the base, a pair of upwardly and outwardly extended sides interconnecting the base and platforms; a first set of engines adapted to draw air from above the base and thrust the air rearwardly below the first platform; a second set of engines adapted to draw air from above the first platform and thrust the air rearwardly below the second platform, the aircraft being buoyantly supported on the thrust stream. Elevators are provided to direct the flow of thrust from the engines and a forwardly disposed retractable member pivotally connected to the base and disposed between the sides to occlude a direct flow of air into the first engines to effect a cavity reduction at the prow of the aircraft to facilitate rapid lift thereto. Conventional rudders and landing gear are also provided for obvious purposes.
