Abstract
A remote-controlled autogyro visually and functionally simulates a helicopter with stub wings (e.g. the Hind D), so that an expendable helicopter-simulating target is produced. The target has a fixed angle rotor shaft, the rotor being solely aerodynamically controlled. The rotor blades have a negative pitch angle, and a positive conning angle. The engine is mounted at the front of the fuselage and has a downthrust angle, and the horizontal stabilizer also slopes downwardly aft. The rotor is at about the center of lift (horizontally) of the wings, and the wing span is about 50-60 percent the length of the fuselage. The ailerons and tail rudder are electrically interconnected. Remote control is provided for the elevators ailerons, and engine speed.
Claims20
A wheel less, hand launchable remote controlled autogyro having a fuselage section simulating the fuselage of a helicopter with stub, lift-providing, wings.
A remote controlled flying target simulating a helicopter with stub wings, and comprising the elements:
- a fuselage section simulating a helicopter and having fore and aft portions;
- a single rotor;
- a remote controlled engine for powering the target through the air, and mounted on said fuselage section;
- a horizontal stabilizer with elevators;
- a pair of wings each having an air foil, attached to said fuselage section and extending outwardly therefrom;
- said rotor including a rotor shaft upstanding from the fuselage and attached to a rotor head;
- said rotor shaft tilted aft an angle between about 5.degree.-10.degree.;
- said rotor head including air foil blades having a negative pitch angle between about 3.degree.-9.degree.;
- and
- remote control elevator, and roll and yaw structures;
- said elements constructed so that the target is capable of flight simulating combat maneuvering of a helicopter, and for use as a expendable target.
A remote controlled autogyro flying target simulating a helicopter with stub wings, comprising:
- a fuselage section simulating a helicopter, and having fore and aft portion;
- a single rotor;
- a remote controlled engine for powering the target through the air, mounted at the fore portion of said fuselage;
- a horizontal stabilizer, said horizontal stabilizer making an angle, with respect to a line of horizontal movement of the target, of between about 3.degree.-10.degree., sloping downwardly aft;
- a pair of wings connected to said fuselage section extending outwardly therefrom, each wing having an air foil;
- said rotor including a rotor shaft upstanding from the fuselage and attached to a rotor head;
- said rotor shaft tilted aft a fixed angle of between about 5.degree.-10.degree.;
- said engine making a downthrust angle, with respect to a line of horizontal movement of the target, of between about 5.degree.-12.degree.;
- said rotor head including air foil blades having a negative pitch angle between about 3.degree.-9.degree.;
- and
- said target constructed so that it is capable of flight simulating combat flight of a helicopter, and use as an expendable target.
