Abstract: A fault detector for a triplexed mechanical or hydromechanical system which provides for improvement in cost, reliability and weight over previously known balance beam arrangements for achieving redundant two-channel operation to provide a fail-operating first failure mode for operation of aircraft components which require reliable operation for flight safety. The fault detector for a triplexed mechanical or hydromechanical system has a tripodal summing member which receives three mechanical position signals in three different channels with the tripodal summing member retaining a position perpendicular to the force transmitted by the tripodal summing member in response to the position signals and tipping when one of the input signals deviates significantly from the other two. A structure for detecting a malfunction senses a greater amount of movement of the tripodal summing member at its connection to the mechanical position signal which is malfunctioning to provide an indication as to which mechanical position signal is faulty. In response to detection of the faulty operation, a mechanism disconnects the channel having the faulty operation. An alignment structure is operable to restore the tripodal summing member to its normal perpendicular position to enable continued operation by means of the mechanical position signals which are still accurate.

Abstract: The invention relates to a force limiting assembly that includes a force transmitting reciprocating output member carried by an actuator member mounted at one end for rotation in a force limiting assembly housing. A power input member is secured to the actuating member in the housing. The assembly is provided with a release mechanism secured to the assembly housing and mechanically releasably secured to the actuating member to thereby permit the actuating member to move axially into the housing. The axial movement into the housing occurs only when an axial force present in the actuating member, which force is directed towards the housing, exceeds a preset value which results in the sudden release and movement of the actuating member and the power input member into locking cooperation with a portion of the assembly housing. While the power input member is in locking cooperation with the housing, no further input power may be transmitted from the power input member to the actuating member and the force transmitting output member. The release mechanism additionally allows the actuating member and the input member to have limited movement in a direction along the actuating member away from the housing whenever a predetermined force is applied to the actuating member in the direction away from the housing. The input member, when experiencing the movement in a direction away from the housing, cooperatively mechanically locks with a portion of the housing, whereupon no further input power may be transmitted from the power input member to the actuating member and the force transmitting output member.

Abstract: A load limiter has a first disk for translating a first torque from an input and a second disk for translating a second torque from an output. Each of the first disk and the second disk has a ramp in which a torque transmitter, such as a ball is disposed. A first conical brake surface and a second conical brake surface disposed on the first disk or the second disk interact if the first torque and/or the second torque cause relative rotation between the first disk and the second disk.

Abstract: An asymmetry brake includes a housing, a shaft, a pilot brake, a primary brake, and a ball ramp assembly. The shaft of the asymmetry brake is rotatable relative to the housing about an axis of rotation. The primary brake is movably connected with the shaft. The pilot brake is configured to selectively engage the housing to generate a triggering torque. The triggering torque is transferred through the ball ramp assembly to the primary brake, which in response engages the housing to generate a braking torque on the shaft. The disposition of the ball ramp assembly between the pilot brake and the primary brake allows the ball ramp assembly to return to an operative non-separated condition when the pilot brake is disengaged from the housing. The return of the ball ramp assembly to the operative non-separated condition allows the primary brake to disengage from the housing which releases the shaft to rotate.
