Abstract

The invention relates to the technical field of semi-physical simulation test, in particular to a fuel supply simulation device and a semi-physical test device. The fuel supply simulation device provided by the invention comprises a simulation device and a regulation device. The simulation device is used for simulation calculation of the set temperature of fuel in a fuel tank under different working conditions, and the regulation device is used for adjusting the actual temperature of the fuel to be consistent with the set temperature. Under the cooperation of the simulation device and the regulation device, the fuel supply simulation device of the present invention can perform closed-loop control of the fuel temperature, real-time simulation of the change of the fuel temperature under different working conditions is realized, so that influence on functions and performance of a test object by the fuel temperature can be simulated more truly and the authenticity of the semi-physical simulation test can be improved effectively.

Description

technical field [0001] The invention relates to the technical field of semi-physical simulation tests, in particular to a fuel supply simulation device and a semi-physical test device. Background technique [0002] In the development process of aero-engine control system, semi-physical simulation test is a very important control system integration test and an important means to verify and evaluate the function and performance of the control system. The fuel temperature and fuel supply pressure supplied by the aircraft to the engine fuel pump vary with the flight environment, and the changes in the fuel temperature and fuel supply pressure will have an important impact on the engine fuel control system. However, the existing semi-physical test devices usually do not simulate the real fuel temperature, which makes it unable to reflect the function and performance of the engine in the real working environment, which affects the accuracy of the test results.
