An aircraft landing gear actuation system which uses two separate actuation forces to retract aircraft landing gear is disclosed. One of the actuation forces may be provided by an actuator, such as a hydraulic actuator. Another of these actuation forces may be provided by a pressurized fluid that is directed into the actuator through a conduit that extends into a hollow interior of an actuator rod of the actuator. The pressurized fluid may be provided from a pressurized fluid source that contains a fixed volume of pressurized fluid. This pressurized fluid may exert a force on an actuator piston of the actuator or the actuator rod. The pressurized fluid may also be used to dampen the deployment of the landing gear.

An additive manufacturing system and process for manufacturing aircraft parts is disclosed. The process applying an additive manufacturing process to a build tube formed around a longitudinal axial direction of the build tube by rotating the build tube around a longitudinal axis. Then, translating, by the additive manufacturing process, a print-head in a parallel configuration to the longitudinal axis to enable the print-head to deposit an aerospace grade material on a surface of the build tube to form a manufactured component. After completion of the additive manufacturing process, applying another process using a device wherein the device applies a machining process in the longitudinal axial direction to remove the build tube wherein the machining process comprising machining an interior surface of the manufactured component to expose the interior surface of the manufactured component.

A hydraulic fluid system is disclosed herein. The hydraulic fluid system includes a hydraulic motor including an output shaft, a reduction gear box having a first side and an opposing second side, the reduction gear box being coupled to the output shaft at the first side and coupled to a reduction shaft at the second side, and a magneto-rheological fluid brake (MRF) brake coupled to the reduction shaft.

Hydraulic fluid flow control

An aircraft actuation system is disclosed that includes a pair of cylinders, a piston movably disposed in each cylinder, and a roller train that extends between the pistons in the two cylinders. A portion of the roller train is disposed beyond the cylinders to engage a pinion. Movement of the pistons in the two cylinders in opposite directions produces a corresponding movement of the roller train to in turn rotate the pinion. The roller train may be maintained in compression between its two ends by fluid pressure exerted on a common face of each of the pistons in the two cylinders. The cylinders may be disposed in non-colinear relation, including in parallel relation to one another. A guide may be used to maintain rollers of the roller train in a proper orientation for entry into a space between an outer race and the pinion.

A temperature compensating shock strut health indicator system for use with a shock strut comprises a visual indicator comprising a plurality of sectors and a pointer configured to rotate with respect to the visual indicator to point to one of the plurality of sectors. The sector to which the pointer points to is dependent on the shock strut stroke (i.e., the position of the piston with respect to the cylinder). In various embodiments, the visual indicator includes various rings that correspond to a different temperature compensated ideal stroke whereby a crew member can correspond the pointer to the appropriate ring depending on ambient temperature. In various embodiments, the pointer comprises a temperature sensitive material configured to cause the pointer to rotate with respect to the visual indicator to actively compensate for temperature.

A multi-use rescue access tool for forcible entry into buildings and other functions, including a rescue bar with opposed head and sickle blade ends. The head end includes paired jaws on one side and a blunt hook with a strike contact face and an open space for insertion of the blunt hook also including a periphery configured for wrench to open and close hydrant valves. A chisel end on an upper jaw may extend beyond a lower jaw. Opposed ends of the rescue bar are configured for paired interlocks with a halligan bar having a fork lever end and adze pick end whereby a pair of aligned prongs of the fork lever end are abutted against corresponding opposed side walls stepping up to aligned raised surfaces of the sickle blade end in a clasped interlock, coupling aligned prongs with opposed recessed channels of a head end in an extended interlock or coupling the adze pick end between paired jaws of the head end to provide a step on the top surface of the head end of the rescue bar in a stepped interlock. Opposed channels of the head end are configured for further coupling the fork lever end within opposed aligned channels of head end to couple the rescue and halligan bars in a parallel juxtaposition.
