A front wheel of a scooter is pivotally mounted to a frame and includes an upwardly extending shaft supporting a handlebar for steering the scooter. A footpad or peg or pedal, mounted on a spring returned lever, is interconnected with the rear wheel through a gear mechanism supported by the frame. By pumping the footpad, rotation of the rear wheel and forward motion of the scooter occurs. The gear mechanism includes a first gear or sprocket mounted for rotation about the arms of rotation of the rear wheel. A further sprocket coaxially mounted is linked via a drive-chain to a sprocket on an offset shaft. A further sprocket on the offset shaft drives a final, drive sprocket via a further chain. And the final sprocket drives the rear wheel through a one way clutch. Depression of the footpad, peg or pedal moves a rack-like bar longitudinally.

A manual release mechanism for a thrust reverser actuation system electromechanical brake includes a first release plate, a second release plate, at least two balls, and a handle. The first and second release plates each have grooves formed therein that have a cam surface located at a predetermined angle. The release plates face one another such that the grooves in each plate are substantially aligned, and the balls are each positioned in the aligned grooves. The first release plate is configured to rotate, and the second release plate is configured to translate. The handle is coupled to the first release plate to allow manual rotation thereof. In response to rotation of the first release plate, the second release plate will translate and disengage the electromechanical brake.

An emergency stop for a brake device for a motor includes a blocking device, a spring, and an inhibiting material. The blocking device is movable between a first position, at which it allows rotation of the drive shaft, and a second position, at which it at least substantially stops rotation of a drive shaft of the motor. The spring is housed at least partially within the housing, and urges the blocking device toward the first position. The inhibiting material at least partially surrounds the blocking device and/or the spring, and has a melting point that is at least substantially known. The inhibiting material at least substantially prevents movement of the blocking device from the first to the second position when a temperature is below the melting point, and allows movement of the blocking device from the first to the second position when the temperature is above the melting point.

Systems and methods of controlling solid propellant burn rate, propellant gas pressure, propellant gas pressure pulse shape, and propellant gas flow rate, rely on the position of a throttling valve. A throttling valve that is movable to a control position is disposed downstream of, and in fluid communication with, a solid propellant gas generator, and in parallel with a plurality of reaction control valves. The solid propellant in the solid propellant gas generator is ignited, to thereby generate propellant gas. The throttling valve is moved to a control position to attain a desired solid propellant burn rate, propellant gas pressure, and/or propellant gas pressure pulse shape.

A method and apparatus for producing gas, for example for propulsion. Propellant grains are segmented, preferably in symmetrically arranged pairs and preferably about a central channel extending longitudinally between the ends of the grains. Longitudinally extending grains may be ignited at one end only of each grain, at both ends, and/or at one or both ends along with at an interior portion of a grain. In order to maintain a relatively constant center of gravity, symmetrically arranged pairs of grains can be ignited simultaneously. In order to produce a desired pressure versus time profile, the number of ignition points on a grain can be varied.

A rudder pedal assembly exhibits sufficient ergonomic feel for a pilot, and is relatively small in overall size. The rudder pedal assembly includes a plurality of rails disposed non-parallel to each other within a common plane, and a rudder pedal. The rudder pedal is movably coupled to the plurality of rails and is configured to receive an input force in at least a first direction and a second direction. The rudder pedal is further configured, in response to the input force, to move along a path constrained by the plurality of rails in at least the first direction and the second direction, respectively, and within the common plane.

A lock assembly for a thrust reverser system that prevents thrust reverser movement, in either the deploy or stow directions, includes a lock bar and a lock that are configured to be self-aligning with respect to one another. This configuration ensures the lock assembly fully moves to the locked position even if the lock bar and lock are aligned with one another when the lock is being moved into the locked position.

A fluidic diverter valve includes valve element freely disposed within a valve bore. The valve bore has a cross sectional area that varies. As a result, the clearance between the valve element and an inner surface of the valve bore also varies. This variation in cross sectional area, and thus clearance, is such that a force of sufficient magnitude to move the valve element from a seated position is initially applied to the valve element, but the force on the valve element is reduced once it is moved from the seated position. Thus, the impact force upon attaining another seated position is reduced.
