The crash-resistant expansion cylinder buffer comprises an expansion cylinder, a conical head, a piston, a limiting valve block, a spring, an adjusting nut and an oil drainage hole, an oil cavity is formed in the expansion cylinder, and a sealing ring is installed to prevent leakage; according to the crash-resistant expansion cylinder buffer, the working threshold value of the crash-resistant expansion cylinder buffer can be flexibly adjusted, and the buffer can obtain large and stable buffering force in the crash-resistant process; and the crash-resistant expansion cylinder buffers can be directly and reasonably installed in series or in parallel to form a crash-resistant expansion cylinder buffer system, so that the crash-resistant capability of the aircraft is enhanced.

    本发明公开了一种可调节缓冲能力的耐坠毁胀筒缓冲器,包括胀筒、锥头、活塞、限制阀块、弹簧、调节螺母、泄油孔,胀筒内设置油腔,并安装密封圈防止泄露;该耐坠毁胀筒缓冲器可以灵活调节耐坠毁胀筒缓冲器工作阈值,有利于缓冲器在抗坠毁过程得到较大且稳定的缓冲力;也可以直接通过合理串联或并联安装耐坠毁胀筒缓冲器组成耐坠毁胀筒缓冲器系统,加强飞行器抗坠毁能力。
