    摘要: An apparatus for converting a manned aircraft for unmanned flight, the aircraft including at least one pilot control capable of manipulation to affect operation of the aircraft, the apparatus comprising a first actuator and a second actuator each configured to selectively provide movement or resistance to movement in a first manner including linear or rotational motion, a first clutch and a second clutch each configured to selectively couple movement of the associated actuator to the pilot control, and a vehicle controller capable of being selectively enabled to operate the pilot control actuators and clutches providing unmanned operation of the aircraft or disabled providing manned operation of the aircraft. The first actuator has a first scope describing a first amount of allowable movement, while the second actuator has a second scope larger than the first scope.

    摘要: The steering or control force for operating a steering column in an aircraft, especially in a rotary wing aircraft, is stabilized. The steering column influences through an articulated steering or control linkage the elevator assembly or the rotor blade adjustment, whereby a signal is employed which is dependent on the measured flight speed. It is necessary to signal to the pilot at all times how the steering column must be moved. Such signalling must be definite and free of any disturbing influences and the pilot must receive such signalling through the steering column manual force which is a force reacting to the operation of the steering column. For this purpose a speed dependent signal is supplied to a servomotor. This signal rises with the flight speed at least above a preselectable threshold value. The servomotor in turn controls the tensioning state of a spring which is pivoted at one end to the steering column and at the other end to the displacement member of the servomotor. Preferably, the point of articulation between the spring and the steering column is located approximately opposite the point of articulation between the steering column and the steering or control linkage. Additionally, a feedback signal derived from sensing the displacement caused by the servomotor is added to the speed dependent signal. The feedback signal varies in the same sense as the displacement caused by the servomotor and serves to achieve proportionality between the signal S and said displacement.

    摘要: The present steering mechanism, especially for an aircraft includes a manly operable steering member and an automatic steering system. A difference signal formed from a pilot input and trim signal and from a gyro feedback signal is supplied to a force control and damping circuit twice, once directly and once through an authority limit circuit. The output of the authority limit circuit is also supplied to the motors forming part of the automatic steering system. The force control and damping circuit also receives further input signal or signals representing steering information. The output of the force control and damping circuit is connected to the feel unit of the steering system, whereby an immediate manual control by the pilot is effective, however limited against an excessive control or so-called manual over control.

    摘要: In a helicopter, a pilot-actuated lever controls, through linkage mechanisms, a servo valve to drive a hydraulic piston; the piston moves a swash plate which in turn controls movement of rotor blade pitch positioning mechanisms against the force of blade loading, caused by aerodynamic forces. Blade loading, heretofore monitored visually by the pilot on a cruise guide indicator instrument, is used herein to control a secondary input to the servo valve, thereby to alter the position linkage mechanism which causes the force of a spring attached thereto to impose a force on the collective pitch control for blade loadings in excess of one-third of maximum allowable blade loads, in a direction tending to drive the control to lower collective pitch (lower blade loading). This provides "feel" to the pilot in proportion to blade loading when at critical magnitudes. A trim system is selectively actuatable to provide an input to the auxiliary valve which tends to maintain the collective pitch control in a selected position.

    摘要: A system to generate control surface feedback forces in an aircraft employing powered control surfaces. The system is primarily mechanical in nature and includes at least two springs as the force generating elements, and means which predeterminately interconnect the springs, predeterminately vary the preload of one spring, and predeterminately vary the effective spring rates of the springs in correspondence to the flight conditions of the aircraft.
