摘要:
The invention provides a control mechanism for controlling flight of an aircraft, the control mechanism comprising a cyclic control stick (1) that is mounted to tilt (B1, B2) on a carrier structure (4) and that is in engagement with remote mechanical transmission members (2, 3). The stick (1) is arranged as a telescopic member provided with locking means (20) for locking it in a normal-use retracted position, and is equipped with deployment means (21). Unlocking of the locking means (20) and use of the deployment means (21) depend on an assistance device (17) associated with the stick (1) being in a defective state. In the event of such a defective state being detected, the stick (1) is suitable for being deployed so as to increase the comfort of the pilot while manipulating it.

Embodiments of the present disclosure generally provide a device for securing the external control surfaces of an aircraft. A gust lock is described for securing the control surfaces of an aircraft that includes an elongated top plate having a rotably associated strap lock, an elongated bottom plate having a rotably mounted capture piece, and a strap running from the capture piece through the strap lock to a tail section.

A disengage device in an aircraft, which prevents a driving force of a drive unit from transmitting to a control surface, having:a first rod having one end portion connected to the drive unit, the other end portion, and a hollow portion formed to have a predetermined length and open at the other end portion;a branch pipe which is connected to a side wall of the first rod and communicates with the hollow portion;a second rod having one end portion connected to the push-pull rod, the other end portion, and a recess portion formed in a part of a side wall of a portion which extends a predetermined length from the other end portion to the one end portion side and is inserted in the hollow portion; andan engaging member arranged to be freely movable in the branch pipe, which is engagable with the recess portion.

A non-jamming fail safe flight control system with non-symmetric load alleviation capability includes a dual cable control system one for each side of control surface, like an elevator or an aileron, controlled by a pilot but driven by a driving system which allows control surfaces to even out the load from one side to the other without affecting pilots control while—if one side becomes jammed—enabling the pilot, with no extra action, to continue flying the aircraft utilizing the other side. In another embodiment an automatic lock feature ensures that a pilot is able to continue to complete the flight in case of severance of a control cable due to a discrete damage without interruption attributable to the control system. Yet another embodiment utilizing either the same or a separate locking feature enables the pilot to lock the surfaces upon parking the aircraft.

An electrical lock for a moving part prevents the part from moving unless a device controlled by the part is in a safe mode. The invention may find a use in many different environments. The specific example here described is a set of reverse thruster doors on a jet engine. The lock prevents a throttle from applying or removing power unless the reverse thruster doors are properly set for such application or removal of power. The lock is removed when the doors reach full deployment or retraction, respectively, which is appropriate for the direction in which said throttle is moved. These functions are provided under the control of a single solenoid.

The use of a center lock bar which telescopingly receives two telescoping arms, each of which has a control column or shaft grip on its remote end is disclosed. The arms are secured to the parallel control columns by at least one gust lock pin. Provision is made for a throttle mixture lock plate to be secured to the lower portion of the radio lock pan which, in turn, has essentially parallel sidewalls with opposed openings through which the center lock bar passes. Optionally folding extension radio lock pans may be employed for a double stack installation. Finally, means are provided in the form of a lock, whether padlock or internally mounted, to lockingly secure the center lock bar to the two telescoping arms. The method of the invention looks to providing a lock for radios, throttles, and gust locks in a dual control aircraft by stabilizing the two control columns by means of a telescoping member which can accommodate differences in the distance between the parallel control columns of the aircraft. The step in addition to the foregoing of locking is done by securing at least one pin to one of the parallel control columns, and thereafter mounting a central radio stack and throttle control centrally of the central portion of the lock. Once these steps have been followed, a lock removably secures the center lock bar against movement relative to the radio lock pan and the flight controls as well as engine controls.

An automatic neutral position locking system for a control surface of an aircraft. A hydraulic prime mover is provided for moving the control surface. A locking device is capable of locking the control surface against movement. A ratchet-and-pawl device is operatively associated with a rotary drive train between the prime mover and the control surface for actuating the locking device in response to the control surface reaching a neutral position. The ratchet-and-pawl device normally is maintained in inactive condition when hydraulic pressure exists in the prime mover. A pneumatic piston-and-cylinder device, when under pressure, maintains the ratchet-and-pawl device in normally inactive condition. With a loss of hydraulic pressure, the ratchet-and-pawl device is effective to actuate the locking device in response to the control surface itself reaching the neutral position as the control surface moves under external loads.

A shield of rigid sheet metal is of a size and shape to substantially cover the instrument panel of an aircraft. A pair of shrouds on the bottom of the shield are spaced so that each fits over one of the control columns of the aircraft, and aligned holes in each shroud are adapted to receive a padlock to lock the shield in place. The shrouds are of a length to fit closely over the control columns when fully extended to prevent any significant movement of the control column axially and pins, which are secured to the shield, extent through openings in the control columns to prevent any accidental or unauthorized turning. A cylindrical housing open at one end is received over the throttle control, and a lock stem extending vertically from the housing is received in a tube, which is fixed to the shield, when the shield is possitioned on the instrument panel so that there can be no manipulation of the throttle.
摘要:
A device for protecting the navigational instruments and radio equipment mounted on an instrument panel in the cockpit of an aircraft against theft. The device includes a protective cover mounted immediately adjacent the instrument panel and means for locking the potective cover to the control column of the aircraft in a manner such that the aircraft controls will not be damaged in the event that the protective cover is tampered with.

The invention relates to a control column (2) for a copilot of an aircraft, coupled for control of roll and pitch by a linkage (5) to the pilot's control column (1). This linkage comprises two parallel rods (6,7) pivoted on the one hand to the column (1) and on the other hand to a member (13) connected to the column (2) by a double universal joint (14, 17). When operative, the column (2) is locked to the member (13) by a lock bolt (19). This control column can be put out of action by releasing the said bolt and can be secured by hooking to a fixed point, in which case the double universal joint (14, 17) ensures its disconnection from the column (1) and thus prevents any misoperation.
