Aero-engine flight test system and test method

Abstract

The invention relates to an aero-engine flight test system and test method, the test system comprises an unmanned flight test platform (1), the unmanned flight test platform (1) comprises: a fuselage(11), the outer bottom of the fuselage (11) is provided with an installation part for installing a test engine (14); and an operating engine (12) provided on the side of the fuselage (11). According to the test system, on the basis that the test task requirements can be met, the redundancy in the aspects of function, structure and weight is small, the test cost is low, and high economy is achieved; moreover, by additionally installing the test engine, the original operation engine is not influenced, and the original structure of the unmanned aerial vehicle test platform does not need to be modified; besides, the test engine fails and cannot work normally, the original running engine can still meet the flight requirement, no test participant is needed on the test platform provided with thetest engine, and the safety in the test process can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of aero-engine testing, in particular to an aero-engine flight test system and a test method. Background technique [0002] Aeroengine high-altitude tests need to be carried out in the design finalization and airworthiness certification to determine the air-operating characteristics. The domestic GJB241A-2010 "General Specifications for Aeronautical Turbojet and Turbofan Engines" clearly stipulates that "high-altitude tests should be performed on high-altitude platforms or flight Taiwan proceeds". [0003] In the development of foreign civil aeroengines, the flight platform is an indispensable means of development, and each major engine manufacturer has its own flight test platform. Based on considerations of cost, operational safety and engine size, at present, large-scale engines are usually tested in the air on a general-purpose flight test platform, which is generally formed by refitting a general-purpo...

Problems solved by technology

Based on safety considerations, the modification of the flight test platform is usually carried out on a 4-engine or multi-engine aircraft (more than two engines), but in the actual test process, it is found that the cost o
