The invention relates to an electrically-driven hydraulic pump system for a light and small aircraft, and belongs to the field of aircraft design. The invention discloses a light airborne hydraulic actuator system. The system comprises an electric telescopic driver, a main hydraulic actuator and an undercarriage folding and unfolding actuator, the electric telescopic driver provides power for the main hydraulic actuator; the main hydraulic actuator is communicated with the undercarriage folding and unfolding actuator and forms a loop with the undercarriage folding and unfolding actuator; the undercarriage folding and unfolding actuator is connected with the undercarriage; when hydraulic oil in the main hydraulic actuator and the undercarriage folding and unfolding actuator is extruded to flow, the undercarriage folding and unfolding actuator drives the undercarriage to be put down or put up. The invention has the following advantages: 1, the system is simplified, the reliability of the system is improved, and the weight of the system is reduced; 2, energy is reasonably utilized; and 3, under the condition that the motor actuator has a fault, the system can still effectively put down the undercarriage, so that the flight safety is ensured.

    本发明涉及一种供轻小型飞机使用的电驱动液压泵系统,属于飞机设计领域。一种轻型机载液压作动器系统,所述系统包括电动伸缩驱动器、主液压作动器、起落架收放作动器;电动伸缩驱动器为主液压作动器提供动力;主液压作动器与起落架收放作动器连通,且二者组成回路;起落架收放作动器与起落架连接;当主液压作动器及起落架收放作动器内的液压油被挤压流动时,起落架收放作动器带动起落架放下或收上。本发明具有如下优点:1、简化了系统,提升了系统的可靠性,减轻了系统重量;2、合理利用能源;3、在电动机作动器故障的情况下,系统仍可以有效的把起落架放下来,确保飞行安全。
