High speed vertical take-off and landing aircraft

摘要: A high-speed vertical take-off and land (HSVTOL) aircraft comprises a disk-shaped body with annular rotor having rotatable fan assembly driven by redirected jet exhaust gases. The includes blades, each movable airfoil portions, stationary flap portions nozzles located on the trailing edges. Low pressure inflatable O-ring seals bearings are positioned along labyrinth interface between rotor. of is connected to an plenum receiving hot For flight, substantially all gases turbojet engines into main bypass control doors. Converging ducts in just upstream receive direct from radially extending feed tubes nozzles. rotates about reaction force created emission Lift principally provided action assembly; but also gas primary lift flight comes opening portion blades scooping ambient air causing downwash past which turn provides lift. pitch may be changed modulate horizontal gradually closed create aerodynamic, low drag disk. doors within opened allow normal operation cut off flow assembly. Sufficient rotational velocity maintained during maintain gyroscopic stablility. Gyroscopic attitude achieved through phases both horizontal. Specifically, eyeball valves selectively cyclically operated regulate being ejected lower edge roll, as required.
