A multi-use tiltrotor test bench

Abstract

The invention relates to a reusable tilting rotorcraft test stand, which is characterized in that a front beam and a rear beam are the same in structures, the front beam and the rear beam are parallel, the front beam, the rear beam and shaft connecting ribs are matched and connected to define a rectangular frame structure, common ribs parallel to the shaft connecting ribs are arranged between the front beam and the rear beam, an upper wall plate and a lower wall plate cover the rectangular frame structure to form a box section which is fixed to a ground through supports. One ends of the supports are fixed to the ground, and the other ends of the supports penetrate through the lower wall plate to be fixed to the joints of webs of the common ribs and the rear beam, and the joints of the webs of the common ribs and the front beam, and connected to the joints through bolts. The reusable tilting rotorcraft test stand is simple in structure, convenient to make, suitable for tilting rotor wing tests, convenient to remove, high in device stability, safe and reliable.

Description

technical field [0001] The invention relates to the technical field of aircraft structure design, in particular to a multi-use tiltrotor test bench. Background technique [0002] At present, there are few domestic tilt rotor aircraft tests. One of the important reasons is that the test cost is too high, which leads to slow technological progress in this area. In the prior art, a helicopter disclosed in the patent application with the patent No. The blade dynamic balance test bench rotor head twist bar type hub is only applicable to the field of helicopter test technology, especially relates to a helicopter blade dynamic balance test bench rotor head twist bar type hub, not suitable for tilting wings test. The problem that needs to be solved urgently at this stage is to design a test bench with a simple and reasonable structure for the tilt rotor test, so as to save money on the premise of meeting the test requirements. Contents of the invention [0003] The purpose of th...
