The invention belongs to the technical field of aviation cable descending systems, and relates to a helicopter cable descending support installed in a two-point mode. Comprising two cylindrical connectors, two limiting blocks, a front supporting arm, a rear supporting arm, a cross rod, a mounting support, a spherical part, a spherical outer cover plate and a cable descending rope mounting ring. The two cylindrical joints are respectively mounted at front and rear high-position mounting points of the cabin door of the helicopter and are respectively connected with the front support arm and the rear support arm through the two limiting blocks; the cross rod is mounted between the front support arm and the rear support arm; the rope descending rope mounting ring is mounted in the middle of the cross rod and connected with the rope descending rope. On the premise that an existing helicopter high-position installation point structure is not changed, connection between a helicopter structure and the cable descending rope is achieved, the weight of the support is reduced, the difficulty of installing the cable descending support is reduced, and the situation that the aerodynamic performance is affected by fairing cutting when the cable descending support is installed is avoided.

    本发明属于航空索降系统技术领域,涉及一种两点式安装的直升机索降支架。包括:两个柱形接头、两个限位块、前支臂、后支臂、横杆、安装支座、球形件、球外盖板、索降绳安装环;所述两个柱形接头分别安装在直升机舱门处前、后高位安装点,并通过两个限位块分别与前支臂、后支臂连接;横杆安装在前支臂、后支臂之间;索降绳安装环安装在横杆中部,连接索降绳。能够在不改变现有直升机高位安装点结构的前提下,实现直升机结构与索降绳的连接,减轻支架的重量,减少安装索降支架的难度,避免索降支架安装时切割整流罩影响气动性能。
