Abstract: A dynamic conformal aerodynamic seal that bridges the gap between an aircraft control surface and an aircraft wing, stabilizer or tail. The seal has a first edge and a second edge, where the first edge of the seal is rigidly coupled to the aircraft wing, stabilizer or tail and the second edge of the seal is slidably coupled to the control surface by magnetic coupling so that when the control surface pivots relative to the aircraft wing, stabilizer or tail, the second edge of the seal slides along the control surface.

Abstract: A Z-pin including a first bi-metal structure having a first metal strip and a second metal strip bonded together, where the first and second metal strips have different coefficients of thermal expansion, and a second bi-metal structure having a third metal strip and fourth metal strip bonded together, where the third metal strip and the fourth metal strip have different coefficients of thermal expansion. The first and third metal strips are selectively secured together at at least one discrete location so that heating of the Z-pin causes the first and second bi-metal structures to deform relative to each other. The Z-pin is inserted into a composite laminate structure while it is in its uncured state, where curing of the composite structure causes the first and second bi-metal structures to deform relative to each other to lock the laminate layers together.

Abstract: A magnetic latching system is provided for removably latching a panel to an aircraft surface portion. The latching system includes a removable axis panel engageable to a latching land. The panel and land define opposing magnetically attractive surface portions, with a body of magnetic material disposed there between. An inflatable seal is also disposed intermediate the panel and the land. Upon inflation, the inflatable seal is operative to urge the panel away from the land far enough to reconnect magnetic engagement between the panel and the land, sufficient to permit disengagement of the panel from the land.

Abstract: A method for providing air traffic controlled flight of a large number of commercial drones each carrying one or more packages in to and out of an air traffic controlled space around an airport. The method includes providing an outbound corridor from a carrier facility through and out of the air traffic controlled space, where the outbound corridor does not allow any other air traffic to fly therein, and allowing the drones to fly through the outbound corridor to leave the air traffic controlled space without requiring air traffic control. The method also includes providing an inbound corridor through the air traffic controlled space to the carrier facility that does not allow any other air traffic to fly therein, and allowing drones to return to the carrier facility through the air traffic controlled space by flying through the inbound corridor without requiring air traffic control.

Abstract: A permanent faster is disclosed that utilizes an amorphous metal alloy for a retaining collar that is thermoplastically formed on install. The fastener includes a headed pin with locking grooves disposed thereon and a collar having a cylindrical inner wall. Head geometry may be any suitable shape; countersunk, counter bore, flat, etc., and may also be non-rotationally symmetric. The pin is disposed into aligned holes through the work pieces to be secured, and the collar is disposed about the pin over the locking grooves. The collar is heated into a thermoplastic region, something only allowed because of the amorphous metal material properties. The cylindrical wall of the collar is then radically compressed into the locking grooves to affix the collar on the pin. The amorphous metal properties allow use of a smaller fastener, and the thermoplastic region is reached at a temperature which does not damage composite work pieces.

Abstract: A latching mechanism is provided for engaging an aircraft surface panel to a support member. The aircraft panel is provided with a post extending from the lower surface, which extends through a panel support member into a post engagement mechanism. The post engagement mechanism defines a rotatable sleeve, which rotates for locking and unlocking engagement between the post and the post engagement mechanism. Locking engagement continues when power to the post engagement actuator is terminated. The post engagement mechanism may utilize various types of actuators, including mechanical, hydraulic, and pneumatic. The aircraft panel and the panel support member are translatable into and out of abutting engagement independent of the need for any contact with the aircraft panel upper surface.

Abstract: A bi-directional coupler that selectively couples and de-couples a driving element to a driven element. The coupler includes an outer shaft having an outer shaft slot and an inner shaft having an inner shaft slot, where the inner and outer shafts are configured to rotate independently of each other. The coupler also includes a ball bearing provided within the inner shaft slot and having a size so that when the ball bearing is located at a center portion of the inner shaft slot it does not interfere with rotation of the outer shaft, where the ball bearing is held in that location by a magnet located in the inner shaft. Rotation of the inner shaft above a predetermined rotational speed causes the ball bearing to engage the outer shaft slot so as to cause the inner shaft to be locked to the outer shaft and rotate therewith.
