The invention belongs to the technical field of airplane ground strength tests, and particularly relates to a double-engine lateral restraint device. The device comprises two pull rods symmetrically arranged on the left side and the right side of an airplane body to be tested, two adjusting screws and two engine accessories. One ends of the pull rods are hinged to the central symmetry plane of theairplane body to be tested, and the other ends are hinged and fixed. The top ends of the adjusting screws are hinged to a central constraint point; and the top ends of the engine accessories are hinged to the bottom ends of the adjusting screws. According to the double-engine lateral restraint device, restraint of the two engines on the symmetry plane can be achieved, the rigidity of an airplaneis not increased, relative deformation of the two engines is not affected, attitude control over the tested airplane is more accurate, and test assessment is more real.
本申请属于飞机地面强度试验技术领域,特别涉及一种双发动机侧向约束装置,包括在待试飞机机体左右两侧对称设置的两个拉杆、两个调节螺杆以及两个发动机假件;拉杆一端铰接至待试飞机机体的中心对称面处,另一端进行铰接固定;调节螺杆顶端铰接至中心约束点处;发动机假件的顶端与调节螺杆的底端铰接。本申请的双发动机侧向约束装置,能够实现两个发动机在对称面上的约束,且不增加飞机刚度,不影响两个发动机相对变形,使得试验飞机姿态控制更准确,试验考核更真实。
