摘要： An automatic flight control apparatus for aircraft having the desired attitude of the aircraft in a balanced relation to the action speed of the aircraft and utilizing this reference signal to generate a difference signal which corresponds to the difference between the reference signal and a signal representing the actual attitude of the aircraft; this latter signal then is used as one of the control parameters. The difference signal is fed to a control system through a limiter having a limiting range to avoid feeding excessively large difference signals into the control system and thus preventing unstable flight.

摘要： An automatic flight control apparatus for a rotary wing aircraft for controlling the flight condition by utilizing a signal representing the air speed of the aircraft which is added to a bias signal corresponding to the attitude of the aircraft in hovering condition, which added signal is used as a "trim value" signal representing the attitude of the aircraft in a balanced relation to air speed at every instance. A signal representing the difference between said trim value signal and the attitude signal is used as an attitude/speed error signal and is added with the signal representing the difference between the ground speed and the set speed for performing control of the aircraft condition. Also, in order to provide true air speed utilizing a detecting means of the Pitot tube type, when the flight speed is below a predetermined value, a ground speed signal is added with a stored signal representing the difference between the air and ground speeds and the added signal is used instead of the air speed signal to overcome the inaccuracy of the Pitot tube at low speeds.
摘要翻译：一种用于旋转翼飞行器的自动飞行控制装置，用于通过利用表示飞行器的空气速度的信号来控制飞行状态，该信号被添加到对应于飞行器在悬停状态下的姿态的偏置信号，该加法信号用作表示在每一个情况下平均与空气速度关系的飞机姿态的“修剪值”信号。将表示所述修剪值信号与姿态信号之间的差的信号用作姿态/速度误差信号，并且加上表示对于飞行器状态进行控制的地面速度与设定速度之差的信号。此外，为了利用皮托管式的检测装置提供真实的空气速度，当飞行速度低于预定值时，地面速度信号加上表示空气和地面速度之差的存储信号，使用附加的信号而不是空气速度信号来克服皮托管在低速下的不准确性。

摘要： An automatic flight controller for rotary wing aircraft having a setting apparatus for setting the device for the distance from a starting distance signal, a speed signal, and a remaining distance signal corresponding to the remaining distance from the starting spot to the hovering spot whereby the flight of the aircraft can be controlled in accordance with the remaining distance signal. A ground speed signal from a ground speed detecting device is integrated to obtain a signal corresponding to the flight distance from the starting spot and a remaining distance signal is then produced which is equal to the difference between the starting distance signal and the flight distance signal, and, through a function amplifier, a reference speed signal is obtained which corresponds to the remaining distance to be flown at every instance. This reference speed signal is compared with the actual ground speed to provide a speed difference signal which is used as a control signal for controlling the speed of the aircraft. The automatic flight controller may also provide an altitude control system for controlling the collective pitch control mechanism to obtain a desired altitude.

摘要： A speed control device for moving objects which can quickly change the speed of said object from one speed to another selected speed without overshooting comprising means for generating a signal representing the difference between the actual speed and the desired speed and adding a constant bias to said difference signal if said signal exceeds a predetermined value so that said biased difference signal will actuate an actuating means to move the object more quickly toward the desired set speed and to use and integrate the unbiased difference signal when said difference signal is below said predetermined value, which integration can be used to send smaller signals to the actuating means as the moving object approaches the desired set speed so as to prevent overshooting.
