    • Disclosed is a non-rigid vinyl chloride polymer composition comprising 100 weight parts of a vinyl chloride polymer resin, 5-50 weight parts of a graft copolymer modifier and 10-300 weight parts of a plasticizer. The graft copolymer modifier is obtained by graft-polymerizing 25-150 weight parts of an alkyl ester of methacrylic acid having 1 to 4 carbon atoms in the alkyl group or a monomer mixture composed of at least more than 50% by weight of said alkyl ester of methacrylic acid onto 100 weight parts of an acrylic elastomer having a swelling degree of 5 to 25 so that the grafting ratio is not larger than 50%. The acrylic elastomer is obtained by polymerizing a mixture comprising an alkyl ester of acrylic acid having 2 to 10 carbon atoms in the alkyl group or a monomer mixture composed of at least 50% by weight of said alkyl ester of acrylic acid, and a polyfunctional crosslinking agent. The non-rigid vinyl chloride polymer composition has excellent weatherability and impact resistance, and exhibits a good molding processability.

    • 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.
    • 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。

    • 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.
    • 一种用于旋翼飞行器的自动飞行控制器,具有用于将距离起始距离信号,速度信号和对应于从起始点到悬停点的剩余距离的剩余距离信号设置距离的设备的设置装置,由此飞行 的飞机可以根据剩余距离信号进行控制。 来自地面速度检测装置的地面速度信号被积分,以获得与起始点相对应的飞行距离的信号,然后产生等于起始距离信号和飞行距离信号之间的差的剩余距离信号, 并且通过功能放大器获得对应于在每个情况下要飞行的剩余距离的参考速度信号。 该参考速度信号与实际地面速度进行比较,以提供用作控制飞行器速度的控制信号的速度差信号。 自动飞行控制器还可以提供用于控制集体桨距控制机构以获得期望高度的高度控制系统。
