Abstract: An exemplary method includes using a pressure supply device (PSD) to actuate a hydraulic customer includes activating, when in the first position, a first gas generator of the multiple gas generators thereby driving the piston to the second position, pressurizing the hydraulic fluid, and discharging the pressurized hydraulic fluid to the customer; actuating the customer in response to receiving the pressurized hydraulic fluid; resetting the piston to first position by transferring a resetting hydraulic fluid into the reservoir; and exhausting gas and condensate from the gas chamber in response to resetting the piston to the first position.

Abstract: The present disclosure generally relates a high strength, low weight, and low shock rocket body separating joint for the purpose of joining rocket bodies, and method of assembly thereof. The solution combines a radax joint, joined by fasteners, with a flattened bladder and inflation system coupled thereto. Upon activation of the inflation system, the bladder is pressurized and exerts a separating force between the members of the radax joint, overcoming the load carrying capability of the fasteners and breaking apart the radax joint.

Abstract: There is disclosed a device and associated method for impeding the motion of a land vehicle travelling along a pathway on a terrain surface. First and second supports are positioned at first and second sides of the pathway, respectively, each capable of being actuated from a compressed condition to an extended condition. A propulsion system is effective to actuate the supports. A barrier extends between the supports at a mean first height that is effective to permit passage of a vehicle when the supports are compressed and supported by each support at a mean second height effective to impede passage of the vehicle when the supports are extended. When the supports are compressed, vehicles pass over the barrier unimpeded. When the supports are extended, the barrier impedes the motion of a vehicle travelling along the pathway. At least one deceleration cable mechanically couples the barrier to a brake system.

Abstract: A fire is extinguished and suppressed, by a dual stage fire extinguisher. In a first stage, a sufficient amount of an inerting agent is delivered to extinguish the fire. Once the fire is extinguished, in the second stage, a different amount of inerting agent is delivered to the fire to prevent its re-ignition. Since suppression typically requires less of the inerting agent than extinguishing, a reduction in the weight of the inerting agent is achieved with the dual stage process making the system particularly amenable to aircraft applications such as in an engine nacelle or cargo dry bay.

Abstract: There is disclosed a transportable device and associated method for impeding the motion of a land vehicle travelling along a pathway on a terrain surface.

A propulsion system is effective to actuate the supports. A barrier extends between the supports at a mean first height that is effective to permit passage of a vehicle when the supports are compressed and supported by each support at a mean second height effective to impede passage of the vehicle when the supports are extended. When the supports are compressed, vehicles pass over the barrier unimpeded. When the supports are extended, the barrier impedes the motion of a vehicle travelling along the pathway.

Abstract: There is disclosed a transportable device for non-destructively impeding the motion of a land vehicle travelling along a pathway. First and second telescoping devices located on either side of the pathway support a barrier. When the telescoping supports are compressed, the vehicles pass over the barrier unimpeded. When the telescoping supports are extended, the barrier impedes the motion of a land vehicle. At least one deceleration cable mechanically couples the barrier to a braking system. The braking system applies a continuous deceleration force to the vehicle of typically less than 2 g, bringing the vehicle to a stop without damaging either the vehicle or vehicle occupants.
