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.

Abstract: A modular animal cage that may be formed to enclose an area of any given size and which may be used for a wide variety of purposes. A skeletal module is formed by four upstanding corner post members interconnected by eight horizontally extending rods disposed in sets of two. A cage may be formed from the skeletal module by clipping side panels onto the rods forming the sides of the skeletal module. Top and bottom panels may also be provided. The area enclosed by the cage can be expanded by connecting one or more other skeletal modules together in side-by-side open communication.
