An aircraft wing includes a stationary root section and a telescoping end section slideable in the span wise direction, where the loads for the root and extendable end sections are carried predominately by the airfoil composite skins, rather than a framework of spars and ribs as in conventional aircraft wings. In a single-telescoping configuration the telescoping end section slides within the root section as it extends and retracts during flight, and in another, the telescoping end section slides over the root section as it extends and retracts during flight. The aircraft wing can also include a second telescoping distal end section, and can sweep back during flight, while the end sections or distal end sections are extended or retracted.

A rotor-lift aircraft has at least two rotors 1, 2 mounted on spaced parallel axes A1, A2. The rotors rotate in use in planes in which the blade envelope subscribed by the tips of the blade(s) of each of the rotors overlaps with the blade envelope subscribed by the tips of the blade(s) of at least one other of the rotors without intermeshing of the blades.

Vehicle propulsion systems and methods of propulsion are disclosed, as well as embodiments of fans and airfoils, technology that in some applications of the invention can provide both lift and thrust, and propulsion via cross flow fan, manifold and a plurality of airfoils. In some embodiments the invention is directed to the production of lift and thrust, and propulsion generally, based from air produced by a cross flow fan in accordance with the invention disclosed herein. In still further embodiments, lift and thrust may yet be generated from air produced from the cross flow fan even when unpowered, such as in a loss of power or in a stall condition. Applications of the invention apply broadly to propulsion systems, generally; however, some preferred embodiments have particular application for vehicles characterized or used in application such as traditional private and commercial aircraft, ground effects vehicles, military applications, amphibious applications, aerospace, aeronautical, and non-traditional vehicles such as experimental air planes, space craft, hover craft, and the like. The invention in some embodiments comprises technologies addressing preferred air flow, lift, and thrust and the reduction of drag and circulation losses. The invention may be further applicable for incorporation in aircraft and other vehicles wherein the ability to maximize initial vertical lift and takeoff is important, such as in instant take-off and landing, as well as the abilities to hover, to control the flight and landing of aircraft, and control in power-loss scenarios, addressing the prevention of stalls and allowing for controlled descents under continued propulsion. In some embodiments, the invention is further applicable for aircraft, shuttles and other vehicles as a ram jet engine system as a further alternative propulsion technology, having no requirement for forward movement for propulsion upon take-off.

A pump having an increased energy efficiency is provided. The pump has an internal power fluid column and a transfer piston which is reciprocatingly mounted about the power fluid column. The transfer piston defines a product fluid chamber, located above the transfer piston valve, and a transfer chamber, located below the transfer piston valve. The power fluid column has at least one passageway, which allows the fluid inside the power fluid column to be in communication with a power fluid chamber. The power fluid chamber, the transfer chamber, and the product chamber are situated coaxially about the power fluid column.

Canarded deltoid main wing aircraft idea allows for design of large supersonic civil and military aircraft with cruising speeds of up to Mach 3 at the altitude of over 25,000 meters. The fuel consumption per unit of payload of such aircraft would be at least twice lower with a longer range of over 50% when compared to existing supersonic aircraft of the same size. Simultaneously, the flight safety and ride quality during takeoff and landing at low speeds would be similar to the existing subsonic passenger aircraft. A low fuel consumption, long range, high ride quality, and high flight safety of these aircraft are widely opening a door for design of supersonic long range continental and intercontinental passenger aircraft that would be highly competitive with existing long range high subsonic passenger aircraft.

An adjustable-length compression spring comprises a casing filled with pressure fluid. A piston rod is sealingly extended through a guide and seal unit which closes the casing, a piston, which is sealingly guided therein, being joined to the piston rod. The piston divides the casing into two sectional casing chambers, which are filled with pressure fluid. For connection to each other of the sectional casing chambers, provision is made for a valve operated by a valve pin. The casing includes a locking mechanism which comprises a first and a second locking element, the first of which being in pushing connection with a first operating element and the second with the valve pin. They cooperate in the way of a retractable-ballpoint-pen mechanism so that, in a first position of locking, the valve pin takes a position of release with free connection between the sectional casing chambers and, in a second position of locking, it takes a position of blocking with any connection between the sectional casing chambers being shut off. This type of integrated locking mechanism can be made solid, nevertheless needing little space.

A hybrid wing autonomous aircraft having, an airframe, at least one hybrid wing member having an airframe end and an extended end, and having leading and trailing edges and a plurality of control structures, the airframe end coupled to the airframe, and the extended end further configured with a wing extension device, the wing extension device configured to extend a supplemental lifting surface from the extended end, an airframe actuator configured to cause the extension end of the hybrid wing member to move from a first position relative to the airframe to a second position relative to the airframe, wherein the second position is greater in distance from the airframe than the first position.

The rotary gas tap (1) with an electromagnetic safety valve (3), is of the conical regulation member (7) type, and the electromagnetic actuator (3a), being of a smaller power and size, is built entirely into a pipe housing (2a) in the body of the tap. The valve actuator (3a) is of the type where the seal member (9) is lifted by means of a DC voltage. The cylindrical magnetic frame (14) penetrating into the coil (15) is guided inside it, and a magnetic capsule (16) surrounding the coil is of a diameter Dh of around 14 mm, adjusted to that of the housing (8) in the body of the tap (2a). The stroke “R” of the seal member (9) corresponds to a gap (G) greater than 2.5 mm, reaching a sizeable passage opening “A” in the valve (9,10) necessary for a maximum inlet flow (Q) in the tap. At the same time the electromagnetic actuator (3a) is of low power, by means of a low reluctance in the magnetic circuit (13-16), although the diameter “Da” of the cylindrical frame is restricted to less than 4 mm.

A vehicle lift comprises a pair of parallel ramps (2) each of which is pivoted to an upstanding support (1) at one end, wherein the two ramps (2) are connected by a cross-beam (6) located towards the ends distal from the pivots (3) and rigidly secured to the ramps (2), which cross-beam (6) includes a lifting box (7) engageable with a lifting jack (12) and located substantially midway between the two ramps (2) such that lifting forces are directed through the center line of the cross-beam (6). The cross-beam (6) bears against the ground when the ramps (2) are in a downwards position. The jack (12) can be replaced by axle stands (10) when the ramps (2) are elevated.

A vehicle with a body, two front wheels and at least one rear wheel. An airfoil is mounted to the body with adjustability in angle of attack, and at least one of the front wheels is driven to permit acceleration to a cruise speed at which the airfoil provides sufficient lift to raise the rear wheel off the road while the front wheels maintain contact with the road. Lift may be modified by at least modifying velocity and modifying the angle of attack of the airfoil. This vehicle provides advantages in comfort and efficiency due to reduced friction in contact with the road and imperfections on the road. The wing may also be adjusted to increase downward force on the rear wheel.
