The invention discloses an aircraft generating a larger lift from its interior. The fluid channel inside the aircraft communicates with the engine and the ports on the upper surface of the outer shell. With the powerful suction of the engine, the fluid on the upper surface of the outer shell is quickly sucked into the fluid channel via respective ports under conditions of long path, large area, high speed and low air pressure, which results in large lift from the interior of the aircraft. In the course of generating the lift, the fluid resistances of the fluid wall and the fluid hole are sucked into the fluid channel through the ports at the front and the surrounding area of the aircraft, then high-speed fluid is emitted from the rear port. This approach contributes greatly to the transformation of the existing aircraft. The unified big wing significantly improves the lift, the speed and the carrying capacity of the existing aircraft with lowered energy consumption.

An aerofoil component defines an in use leading edge and a trailing edge. The leading edge has at least one serration defining an apex and a nadir. The leading edge has a generally chordwise extending slot located at the nadir of each serration.

The invention relates to airfoils, called jn1431-265 and 1413-362, which operate intelligently by adjusting the variable aerodynamics thereof, not only through the attack and sine angle, but also through the effect of scale (air speed), which, when combined, improve the efficiency of the wings configured therewith by up to 30%, cause the wings to experience a predictable stall and also rapidly recover therefrom, and also making the wings configured therewith more efficient at low speed, which reduces the need to use flaps or slats (“high lift devices”), and, in the event that flaps or slats are used, increase the effect of said airfoils even more. On the other hand, at an increased speed, the aerodynamic variables also adjust by up to a third of the value thereof (the angle of attack remaining unchanged), causing the wing to also be very stable at high speed conditions.

An aircraft wing including a wingbox with an upper cover, a lower cover, and a rear spar. A lower trailing edge panel is provided with a leading edge attached to the wingbox. The wing includes a flap, a flap deployment mechanism which is configured to deploy the flap, and a fairing which covers the flap deployment mechanism. A first end of a link is pivotally attached to the lower trailing edge panel at a first pivot joint, and a second end of the link is pivotally attached to the fairing at a second pivot joint. The second pivot joint is lower than the first pivot joint.

An apparatus and method comprising a rack and a translation mechanism. The rack may be configured to hold components. The rack may comprise movable rack segments that are movable independently of each other. The translation mechanism may be configured to move a portion of the movable rack segments relative to another portion of the movable rack segments inside a platform such that internal access to at least a portion of the components is provided inside the platform.

An aerodynamic structure incorporated in an aircraft control surface (10) provides a spar (16) extending along at least a portion of the control surface in a direction and the spar includes a plurality of bends along the direction of extension along the control surface to provide space to accommodate actuator fittings or other structural or operational requirements.

An aerodynamic lifting system for a VTOL aircraft is provided that includes a lifting structure defining a leading edge portion, a trailing edge portion, an upper surface extending between the leading edge portion and the trailing edge portion, and a lower surface extending between the leading edge portion and the trailing edge portion. A plurality of leading edge and trailing edge movable flaps, along with leading edge openings and trailing edge openings are employed to direct a flow of air, including along an upper surface of the lifting structure. During transition from a VTOL stage to forward flight, when a first leading edge movable flap is in a closed position, a net forward thrust is provided by the flow of air at the leading edge portion.

An air vehicle is provided including: a main lift generating wing arrangement having a port wing and a starboard wing, empennage and main propulsion system. The air vehicle further includes a distributed electrical propulsion (DEP) system having secondary electrical propulsion units coupled to each one of the port wing and the starboard wing. The main propulsion system is configured for providing sufficient thrust such as to enable powered aerodynamic flight of the air vehicle including at least: powered aerodynamic take off absent operation of the DEP system; and powered aerodynamic landing absent operation of the DEP system. The DEP system is configured for selectively providing at least augmented lift to the main lift generating wing arrangement in at least landing. A method for landing an air vehicle on a moving platform under separated wake conditions is also provided.
