An aircraft is provided. The aircraft includes fuselage (11), an aerodynamic element (12) extending from the fuselage and including a main section (15) and an adjustable section (16) which is adjustable relative to the main section, a power distribution unit (PDU) (25) configured to generate torque to drive an adjustment of the adjustable section, an actuator (30), torque tubes (40) and elastomeric couplings (50). The PDU is disposed proximate to a fuselage-aerodynamic interface. The actuator is disposed along the aerodynamic element and is receptive of the torque for driving the adjustment of the adjustable section. The torque tubes transmit the torque from the PDU to the actuator and are arranged between the PDU and the actuator such that adjacent torque tubes define an obtuse angle. The elastomeric couplings are disposed at respective ends of each of the torque tubes to enable torque transmission between at least the adjacent torque tubes defining the obtuse angle.

The present invention refers in general to the configuration and manufacturing method for a trailing edge (3) of an aircraft airfoil (2), such as a control surface or a lifting surface. The trailing edge of the invention is formed and configured by upper and lower composite covers (4,5), which are stitched to each other with a metallic wire (9), such as the metallic wire (9) is electrically in contact with upper and lower metallic meshes (6,7) to provide electrical continuity between meshes. According to the method of the invention, upper and lower covers (4,5) configuring the trailing edge (3), are stitched with the metallic wire (9) before curing the covers, so that the metallic wire gets embedded within the composite material. The invention provides a trailing edge (3) for an aircraft airfoil (2), which is easy to manufacture and that at the same time fulfills aerodynamic, mechanical and electrical conductivity requirements.

A system for controlling a magnitude of a sonic boom caused by off-design operation of a supersonic aircraft includes a sensor configured to detect a condition of the supersonic aircraft. The system further includes a control surface that is mounted to a wing of the supersonic aircraft. The system still further includes a processor communicatively coupled to the sensor and operatively coupled with the control surface. The processor is configured to (1) receive information from the sensor indicative of the condition of the supersonic aircraft, (2) determine that there is a deviation between a lift distribution and a design-condition lift distribution based on the information, and (3) control the control surface to move in a manner that reduces the deviation. The magnitude of the sonic boom is reduced when the deviation is reduced.

A method of controlling an elevator of an aircraft may include identifying a current stabilizer angle of incidence of a stabilizer of the aircraft. The stabilizer may include an elevator pivotably coupled to the stabilizer. The method may further include comparing the current stabilizer angle of incidence with a threshold stabilizer angle of incidence, and selecting an elevator position limit that is more restrictive if the current stabilizer angle of incidence is greater than or equal to the threshold stabilizer angle of incidence. The method may additionally include moving the elevator to a commanded elevator position that is no greater than the elevator position limit.
