Reverse thrust test device for engine thrust reverser life performance detection

Abstract

The invention discloses a reverse thrust test device for aeroengine thrust reverser life performance detection and belongs to the technical field of aeroengines. Via use of the reverse thrust test device, an engine thrust reverser is individually singled out, an assembling mode of the thrust reverser on an engine is simulated, stress conditions of the thrust reverser in a maximal reverse thrust condition can also be simulated, and a hydraulic oil cylinder is used for simulating loads of the thrust reverser and applying pressure on the thrust reverser; the reverse thrust test device comprises arear loading part, a front right loading part, a front left loading part and a loading control part that are independently designed and are connected with the thrust reverser. The reverse thrust testdevice disclosed in the invention can be used for detection and testing of strength and fatigue life of the thrust reverser; based on the detection and testing, an engine thrust reverser can be evaluated, and therefore strength and fatigue life of an engine mussel shell type thrust reverser can be evaluated and detected. Due to adoption of split type design, the reverse thrust test device can beapplied to engine thrust reversers different in dimension and size; the reverse thrust test device is simple in structure and easy to process.

Description

technical field [0001] The invention relates to an aeroengine thrust reverser technology, in particular to a thrust reverser test device used for testing the strength and fatigue life performance of an aeroengine thrust reverser, and belongs to the technical field of aeroengines. Background technique [0002] In the field of aviation, in order to verify whether the aeroengine thrust reverser can meet the landing service requirements of the aircraft, the parameters such as strength, fatigue and service life of the thrust reverser must be assessed and tested. At present, among the detection technologies used for the strength and fatigue life of aeroengine thrust reversers, the entire thrust reverser is tested with the engine in China, and there is no test for the strength or fatigue life of thrust reversers; and there are no foreign countries. It is a test device specially designed for testing parameters such as strength and fatigue life of clamshell thrust reversers of aero-e...
