20100025537 | Leading Edge Flap Apparatuses and Associated Methods - The present invention is directed generally toward leading edge flap apparatuses and corresponding methods. One aspect of the invention is directed toward an aircraft system having an airfoil, an actuator driver, and a leading edge device with two flow surfaces and six links. In a further aspect of the invention, the flow surfaces of the leading edge device are at least approximately located in the same position when the actuator driver is in two different positions. Another aspect of the invention is directed toward an aircraft system having an airfoil and a leading edge device movable between at least a retracted position and an extended position along a motion path having two segments. The second flow surface can be positioned generally behind and/or generally above the first flow surface when the first and second flow surfaces are located in the first segment of the motion path. | 02-04-2010 |
20110024575 | LEADING EDGE FLAP METHOD - A method of reducing drag of a leading edge device having first and second flow surfaces includes coupling the first flow surface to an airfoil and coupling the second flow surface to the first flow surface. The leading edge device may be moved between a retracted position and an extended position. The second flow surface may be positioned generally behind the first flow surface during at least a portion of the movement of the leading edge device between the retracted and extended positions | 02-03-2011 |
20150083867 | LEADING EDGE VARIABLE CAMBER SYSTEM AND METHOD - A system for varying a wing camber of an aircraft wing may include a leading edge device coupled to the wing. The leading edge device may be configured to be actuated in an upward direction and a downward direction relative to a retracted position of the leading edge device. | 03-26-2015 |
20150096293 | SMART SUSCEPTOR FOR A SHAPE MEMORY ALLOY (SMA) ACTUATOR INDUCTIVE HEATING SYSTEM - A system for heating a shape memory alloy (SMA) actuator may include an SMA actuator, a smart susceptor, a plurality of induction coils, and a control module. The SMA actuator may have at least one layup. The SMA actuator may be selectively heated to a transition temperature. The smart susceptor may be in thermal contact with the at least one layup of the SMA actuator. The induction heating coils may be configured to receive an alternating current and generate a magnetic field based on the alternating current. The magnetic field may create an eddy current in at least one of the SMA actuator and the smart susceptor to heat the SMA actuator to the transition temperature. The control module may be configured to drive the alternating current supplied to the induction heating coils. | 04-09-2015 |
20150246730 | Systems and Methods for Predicting and Controlling Ice Formation - A system and method for operating an ice detection and deicing system are provided herein. The ice detection and deicing system may use changing magnetic properties of various components caused by temperature changes to detect conditions conducive to, or indicating, ice formation. The ice detection and deicing system may further use eddy currents induced in one or more layers of the system to increase the temperature of the one or more layers to reduce the amount of ice formation or reduce the probability of ice being formed. | 09-03-2015 |
