摘要:
A VTOL vehicle including a fuselage with two foldable wings, two tiltable nacelles attached to the wings, a vertical stabilizer, a horizontal stabilizer, and two auxiliary thrusters. Each nacelle contains a system of vanes located at the rear opening thereof, and actuators are provided for extending and retracting the vanes in conjunction with nacelle tilting mechanisms to deflect the airflow over a predetermined range of angles from the horizontal. Each nacelle also contains two rotary engines, each of which directly drives a fan. The fans face each other and operate in counter-rotating directions at the same rotational speed. An alternative embodiment includes two additional nacelles attached to the fuselage instead of having the auxiliary thrusters. A redundant computerized flight control system maintains stability of the vehicle as it transitions from one flight mode to another.

A charge cooled rotary engine includes a housing (204), a first end plate (206), and a second end plate (208). The housing and end plates combine to define a closed chamber (210). A rotor (202) disposed within the housing includes three flanks (215), a cylindrical hub (213), and a web (214) extending transversely from the hub and joining medial portions of the flanks to the hub. The web, flanks and hub form rotor cavities on opposite ends of the rotor. Inlets formed in the end plates for receiving a fuel/air charge terminate in entry ports (220, 232) facing the closed chamber. Distribution chambers (224, 236), formed in the end plates adjacent the entry ports, are open to the closed chamber. The entry ports directly communicate with the rotor cavities and are isolated from direct communication with any of the intake, compression and combustion chambers by the rotor flanks.

Avion à décollage et à atterrissage verticaux comprenant un fuselage (10) présentant quatre nacelles (12, 14, 16 et 18), trois stabilisateurs verticaux (20, 22 et 24) ainsi qu'un stabilisateur horizontal (26) fixés au fuselage (10). Le fuselage (10) et les nacelles (12, 14, 16 et 18) sont des corps de sustentation configurés pour former conjointement un corps de sustentation aérodynamique coopérant avec le stabilisateur horizontal (26) afin de donner à l'avion une sustentation aérodynamique en vol vers l'avant. Chaque nacelle contient deux moteurs rotatifs (60 et 62) entraînant directement des soufflantes correspondantes (64, 66) se faisant face mutuellement et fonctionnant dans des sens de contre-rotation. Chaque nacelle (12, 14, 16 et 18) contient également un système d'aubes (82) situé au niveau de son ouverture arrière (58), ainsi que des dispositifs destinés à étendre et à rétracter les aubes (82). Un système de commande de vol informatisé à triple redondance maintient la stabilité de l'avion lorsqu'il passe d'un régime de vol à un autre, ainsi qu'en vol.

摘要:
A robotic or remotely controlled flying platform (10) with reduced drag stabilizing control apparatus constructed having an air duct (12) with an air intake (14) on the top and an exhaust (16) at the bottom, containing supported therein a clockwise rotating fan (22) and a counter-clockwise rotating fan (24). Directly below the perimeter of the air duct exhaust are mounted a plurality of trough shaped air deflection assemblies (32) each including a rotatably adjustable half trough (44) for selectively scooping a portion of the drive air, and a stationary adjacent half trough (36) for receiving the scooped drive air and redirecting it outward and upward from the air duct. A centrally positioned plate (112) has a plurality of rods (106), each pivotably connected between the plate (74) and a corresponding lever associated with each of the adjustable half troughs (44) so as to couple the adjustable half trough (44) in or out of the drive air steam according to the position of the plate (74), thereby providing control over the pitch and roll of the flying platform. The plate is driven by first and second motors responding to input control signals. The control signals also direct the yaw of the flying platform by selectively providing independent speed control to each of the clockwise and counter clockwise fan motors resulting in duct rotation in a clockwise or counter clockwise direction accordingly.

摘要:
A VTOL aircraft including a fuselage (10) with four nacelles (12, 14, 16, and 18), three vertical stabilizers (20, 22, and 24) and a horizontal stabilizer (26) attached to the fuselage (10). The fuselage (10) and the nacelles (12, 14, 16, and 18) are lifting bodies that are configured to jointly form an aerodynamic lifting body which cooperates with the horizontal stabilizer (26) to provide aerodynamic lift to the aircraft in forward flight. Each nacelle contains two rotary engines (60 and 62) directly driving corresponding fans (64 and 66) which face each other and operate in counter-rotating directions. Each nacelle (12, 14, 16, and 18) also contains a system of vanes (82) located at the rear opening (58) thereof, and devices for extending and retracting the vanes (82). A triple redundant computerized flight control system maintains the stability of the aircraft as it transitions from one flight regime to another as well as in flight.
