A rotorcraft (1) having: a lift rotor (5); a wing (10) extending from a first end (11) carrying a first propulsive propeller (21) to a second end (12) carrying a second propeller (22); landing gear (30); and a tail (40). The rotorcraft (1) is provided with two fuselages (51, 52) secured to said wing (10) between said first and second propulsive propellers (21, 22) in such a manner as to present an inter-fuselage space (60) having no propeller between said fuselages (51, 52), each fuselage (51, 52) including at least one undercarriage of said landing gear (30).

Systems and methods for mechanically rotating an aircraft about its center-of-gravity (C.sub.G) are disclosed. The system can enable the rear, or main, landing gear to squat, while the nose landing gear raises to generate a positive pitch angle for the aircraft for takeoff or landing. The system can also enable the nose gear and main gear to return to a relatively level fuselage attitude for ground operations. The system can include one or more hydraulically linked hydraulic cylinders to control the overall height of the nose gear and the main gear. Because the hydraulic cylinders are linked, a change on the length of the nose cylinder generates a proportional, and opposite, change in the length of the main cylinder, and vice-versa. A method and control system for monitoring and controlling the relative positions of the nose gear and main gear is also disclosed.

Wings do not produce lift. It is the thrust provided by an engine (or engines) that enable an aircraft to rise off the ground.

Aircraft landing gear forward trunnion support assemblies and related methods are described herein. An example aircraft wing disclosed herein includes a rear spar having a rear side and a front side opposite the rear side and a forward trunnion support assembly. The forward trunnion support assembly includes first and second vertical support fittings coupled to the rear side of the rear spar, and a trunnion housing with a bearing. The trunnion housing is coupled between the first and second vertical support fittings. A central axis of the bearing is perpendicular to the rear side of the rear spar. The forward trunnion support assembly also includes a side load fitting disposed on the rear side of the rear spar. A first end of the side load fitting is coupled to the second vertical support fitting, and a second end of the side load fitting is coupled to the rear spar.

A flying machine includes a flying machine body including a rotor blade; a frame including a frame body supporting the flying machine body, and a pressing section that is pressed against a target object at least at two locations separated along a direction orthogonal to a width direction of the frame body; and a detector fixed to the frame, and having a detection direction that is a direction orthogonal to a direction joining the two locations together and facing toward the target object.

An aircraft landing gear support (1) including: a support member (such as a landing gear rib (2)) and a plurality of pintle supports (5, 7, 8) (typically in the form of lugs) which form a pintle support arrangement for holding a pintle on which a landing gear assembly may be rotatably supported. The lugs are removably attached to the gear rib.

An unmanned rotorcraft has a lift module having a propulsion system and coaxial rotors driven in rotation by the propulsion system. The rotorcraft includes a payload support system adapted to couple an external payload directly to the lift module. The rotorcraft is devoid of provisions for human passengers.
