A convertiplane has the ability to take off like a helicopter and then fly horizontally like a conventional aircraft. The aircraft includes a variable incidence front wing of variable span located below the fuselage and mounted on a structure in the form of a venturi tube, a rear wing having two propellers for controlling the stability of the vehicle in pitch and roll installed therein, two counter-rotating, pivotally mounted ducted propellers equipped with four flaps orthogonal to each other provided on the sides of the cockpit, engines placed behind the cockpit close to the center of gravity, a static balancing system for controlling the center of gravity of the aircraft consisting of a weight placed in the lower part of the fuselage, self-propelled on the track rack longitudinally to the fuselage, and a digital flight control system.

A system and method to control flight of an aircraft. The aircraft (101; 1001) having an engine (111; 1017) with a rotatably nozzle assembly (401) configured to create forward propulsion and yaw control of the aircraft (101; 1001). The engine exhaust (129c) passing through the nozzle (401) is redirected with a valve (419) disposed within the nozzle (401). Lift is created with a lift system (1009) carried by the wing (1007) of the aircraft (1001). Additional lift is created during flight with a retractable wing extension (1015) disposed within the wing (1007) of the aircraft (1001).
摘要:
A shape-changing structure has a superelastic metal foam structural member that changes shape (morphs) to change configuration of the structure. The superelastic metal foam structural member changes shape while maintaining a continuous outer surface, with the continuous metal foam material inside the outer surface expanding, contracting, or otherwise changing shape. The superelastic metal foam material may be heated above a transition temperature to allow it to change shape, and then cooled to cause it to increase in strength, more easily maintaining its new shape. The superelastic metal foam material may be a suitable alloy, for example a nickel titanium alloy, that exhibits superelastic (pseudoelastic) behavior. The superelastic metal foam material may be a shape memory alloy material that returns to a set shape upon moderate heating. The superelastic metal elastic foam structural member may be heated either by an internal heat source or by external heating.

摘要:
A method and apparatus (110) for controlling movement of an aircraft. An aerodynamic function desired for controlling the movement of the aircraft (106) at a particular altitude is identified. The aerodynamic function identified is part of a group of aerodynamic functions (122) used to control the movement of the aircraft (106) at a number of different altitudes (104). A group of inflatable blades (120) is filled with a fluid (116) to a pressure that corresponds to the aerodynamic function. The group of inflatable blades (120) at the pressure has a shape (208) and a group of dimensions (210) that provide the aerodynamic function.
