Abstract: An unmanned aerial vehicle (UAV) jettison apparatus. The UAV jettison apparatus may comprise a payload bay, fairing, ejector plate, and releasable latch. The payload bay may be mounted beneath an aircraft and may have an inner space and a top plate attached therewith. The fairing may substantially cover the inner space of the payload bay and may have an opening positioned directly below the top plate. The ejector plate, which may be spring-loaded, may substantially cover the opening and may be used to mount the UAV. The releasable latch, which may be disposed between the top plate and the ejector plate, may releasably lock and hold the UAV in a stowed position and, upon release, may allow the ejector plate to move into a launch position, such that the UAV is released and jettisoned from a larger aircraft.

Abstract: A carrier of a spacecraft can include multiple latch assemblies that are linked together and held in place by one notched bolt or main shaft, which is out of the main load path. The latch assemblies secure the payload (e.g., CubeSat device) within a carrier by interfacing with pin assemblies on the payload. To deploy the payload, the shape memory alloy actuator is fired which causes a series of springs and preload forces to rotate latches of the latch assemblies out of the path of the pin assemblies. Once the latches are out of the way, the payload is deployed by a spring-loaded pusher assembly and guided through deployment using rollers. Each latch assembly is preloaded in tension using a corresponding preload lug of a receiver assembly.

Abstract: An extendable sway brace for a rack for an airborne payload. The sway brace is extendable. A mechanism for extending the sway brace includes means for preventing extension of the sway brace when the pressure exerted by the brace on a payload reaches a predetermined pressure. The means for preventing extension of the brace may include, for example, one or more pre-loaded springs. In this case, extension of the brace is prevented when the springs are compressed by a predetermined amount. The invention also provides a rack for an airborne payload comprising a sway brace of the invention.

Abstract: A rapid air transportation system for humans, animals, materials or facilities, comprises of rapid coupling of a carriage on land to the tether of a hovering aircraft using quick coupling methods and rapid de-coupling of the same at the end of transportation and landing of the carriage, without landing the aircraft.

Abstract: A suspension lug for releasably suspends loads under aircraft. The suspension lug has a lug eye and a threaded base and a rotation mechanism is inserted into the threaded portion. When the suspension lug is threaded into a compatible well in the load and the load is released from the aircraft, the rotation mechanism causes the suspension lug to rotate by ninety degrees from an initial orientation in which the face of the lug eye is pointed in the direction of flight to a final orientation in which the edge of the lug eye is pointed in the direction of flight. The rotation of the lug eye significantly reduces the drag on the load. Also described are methods of manufacturing and using the suspension lug of the invention.

Abstract: A system for releasing an article such as a munition or store from an aircraft employs a sway brace or cradle built into the structure of a bomb rack from lateral or pitching motion before it is released. A claw mechanism is driven out of the sway braces into the article to hold the article in place on the sway braces. The claws retain the article in the sway braces until the article is no longer influenced by the sway braces.

The power source has a fuel supply of a flowable combustible fuel, an oxidizer supply of a flowable oxidizer, a combustion chamber that controllably receives the combustible fuel from the fuel supply and the oxidizer from the oxidizer supply and forms a combustible mixture thereof, an igniter that controllably ignites the combustible mixture in the combustion chamber, and a combustion-gas line extending from the power source to the store ejector.

Abstract: There is provided a store ejection system and method for mounting and ejecting a jettisonable store. The system uses a pressurized non-pyrotechnic fluid from a fluid source as the source of energy and the transfer mechanism. An actuation system includes an accumulator for receiving and storing the fluid from the pressure source, a poppet valve for controlling a flow of the fluid from the accumulator, and a controller for actuating the poppet valve to an open position in response to a control signal to jettison the store. A pneumatically-driven jettison mechanism for releasably retaining the store is fluidly connected to the poppet valve such that actuating the poppet valve to the open position releases the pressurized fluid in the accumulator to flow to the jettison mechanism, thereby actuating the jettison mechanism to jettison the store.

Abstract: A payload dispensing system for an aircraft is disclosed that includes a housing mounted to the aircraft. A hollow shaft is mounted to the housing having an open first end and a closed off second end with a hole therethrough. The payload includes an aperture having a first end on an external surface thereof and a second end in the interior therein. A wire cable releasably secures the payload to the housing such that the hollow shaft extends into the aperture of the payload. A compression spring is mounted at least partially within the hollow shaft, having a first end in contact with the second end of the hollow shaft and a second end in contact with the second end of the aperture within the payload, the spring having a compressed position when the hollow shaft is within the aperture in the payload and asserts a force tending to separate the payload from the aircraft.

Abstract: A pin puller combines an actuator with an anti-friction release mechanism, according to a bilaterally symmetric geometry. The anti-friction tension release mechanism ensures that only negligible friction forces need to be overcome to operate the tension release mechanism. Thus, the actuator is isolated from the large tension force that bears on the tension release mechanism. The bilateral symmetric aspect of the structure provides for mechanical redundancy, so that, in the event that one half of the pin puller fails, it is sufficient that the other half operate properly for the tension to be successfully released. This pin puller avoids premature release because it is not susceptible to static electricity or electromagnetic radiation. The pin puller also avoids generation of large shock waves due to its slow speed of operation and because of the gradual release interaction of mechanical parts within the anti-friction release mechanism.
