In order to provide a compact, high-performance drive device for aircraft, in particular for power gliders, which comprise a propeller which is driven by a motor, preferably by an electric motor, and the blades (6) of which can be tilted towards the propeller shaft (15) by way of a joint and in the tilted-out position pass through a running gap (5) for the propeller formed between the nose, in which the generally minimal conditions of space are utilized in an optimum manner and which ensures the...

An aircraft rotor and an aircraft which aircraft has a body and a rotor arranged to it, the rotor having at least two blades. The rotor is arranged to rotate around a substantially vertical axis. The blades are arranged in such a manner that, when rotating, they form a conical surface, whereby to provide ascending force, the ascending force coefficients of the blades are adjusted to be positive and to provide propulsive force, the ascending force coefficients of the blades on the forward side an...

An aerial spray boom 11 for an aircraft includes: an elongated housing 21 secured to the aircraft wing 12, the housing having one or more openings 22 along its length; a conduit 23 having a liquid supply passage 26 and a plurality of spaced-apart nozzles 27 that are aligned with, or extend through housing openings 22, conduit 23 being mounted in said housing for arcuate movement about its longitudinal axis through a prescribed arc that defines variable spraying positions; and a conduit actuator ...

A fighter aircraft achieves low aerodynamic drag and radar signature without sacrificing flight performance through a unique arrangement of the air inlets, the weapons bays, and the main landing gear. Separate main and auxiliary weapons bays permit a narrower fuselage than could be be obtained with a single common bay. Also, the auxiliary weapons bays and the landing gear can be aligned outboard of the main weapons bay without needing to increase the length or width of the aircraft. The air inta...

An autogyro has a teetering semi-rigid rotary wing with rigid rotor blades. The angle of attack (blade pitch) of the rotor blades is fully adjustable in flight continuously over an operational range, and varies along the blade length. A prerotator rotates the rotor blades up to takeoff speed at minimum drag, no lift and optimum engine efficiency. Engine power is disconnected from the rotor blades and their angle of attack is changed for optimum lift to facilitate smooth vertical takeoff. Rotor b...

An aircraft divan which includes a strong, rigid base structure having a plurality of substantially strong, yet lightweight tubular frame members secured, so as to define the base structure, by a plurality of substantially strong, yet lightweight connectors, each of the connectors having an exterior wall structure which defines at least one interior cavity and at least two tube receiving openings wherethrough the tubular frame members pass into securing disposition within the interior cavity of ...

A self-propelled dolly for the movement of aircraft. The dolly includes a pair of laterally spaced apart first ground-engaging wheels. Each wheel is mounted about a portion of a split first axle mounted in a corresponding pair of spaced apart parallel members of a bifurcated chassis portion. The dolly also includes one or more second ground-engaging wheels that are mounted on a second chassis portion pivotally connected to the bifurcated chassis portion about a substantially vertical axis. The s...

A wing made of composite fibre materials, especially carbon fibre reinforced plastics, comprises shell components having a thin-walled, pre-formed wing skin and tubular rods as stringers. The stringers are provided with a connection element and a compression plate at the fuselage end of the wing. The external sides of the compression plates are all in one plane. The wing is attached by screws, which are screwed through the connection element at the fuselage side into the connection elements of t...

An aircraft comprises a hollow elongated body having a plurality of short wings projecting outwardly form the body in a vertically stacked array. The wings transverse substantially the entire length of the body. Engines with diameters substantially equal to the maximum width of the wings are mounted behind the wings, with at least one engine mounted on either side of the aircraft. Honeycomb structures mounted behind each engine cause the air thrust rearward by the engines to be directed as a smo...
