Problems solved by technology
Most of the existing tests are based on empirical calculations or environmental chamber simulations. The working conditions of components can be preliminarily calculated through empirical formulas, but there are still errors in the accuracy; and environmental chamber simulations also have the disadvantages of high cost and complex systems
Especially for the test of the aircraft fuel system, since the fuel system is the core component of the aircraft, if there are errors in the test, there will be hidden dangers in the flight of the aircraft

Description
technical field [0001] The invention relates to the technical field of fuel system testing, in particular to a testing device and method for simulating an aircraft fuel system in a high-altitude environment. Background technique [0002] With the rapid application and development of aviation technology, more and more military and civilian fields have applied aviation means to improve efficiency and save costs, such as search and rescue, broadcast, investigation, medical rescue and so on. As the flight altitude increases, the ambient temperature and pressure gradually decrease. In order to maintain the flight safety and performance of the aircraft, it is necessary to conduct simulation tests on the components of the aircraft in the early stage. Most of the existing tests are based on empirical calculations or environmental chamber simulations. The working conditions of components can be preliminarily calculated through empirical formulas, but there are still errors in the acc...
