Abstract

A small-flow incoming flow parameter simulation system is characterized in that a cooling water system is respectively communicated with a stable measurement section, an air inlet spray pipe, a hot air switching and bypass device, a cooling device and a tail chamber, and provides cooling water for cooling the components; a liquid fuel supply system and a gas fuel supply system provide fuel for the main gas inlet path fuel heating device; an oxygen supplementing system provides liquid oxygen for the main gas inlet path oxygen supplementing mixer and is used for combustion of fuel in the main gas inlet path fuel heating device; a particle loading system is used for loading particles for a test; and a process gas system is communicated with an operation gas source of a pneumatic valve of the system. According to the small-flow incoming flow parameter simulation system, accurate simulation of small-flow incoming flow parameters can be effectively achieved, the mass flow of particles can be accurately and effectively controlled, an effective closed-loop control system is formed, and the test state is effectively observed.

Description

Technical field[0001]The present invention relates to the field of testing platform tests, and more particularly to a small flow of flow vectors analog intake system and testing desk.Background technique[0002]A small flow-flow parameter analog intake system is an important part of the small flow to flow parameter simulation testing platform, however, in the prior art, there is no effective small flow to stream parameters accurate simulation test bench to achieve small flow The parameter is precisely simulated. At the same time, there is no particle load device to accurately control the mass flow of the particles, and cannot form an effective closed-loop control system. In addition, effective observations cannot be performed for the test state, so the parameters of the flow of traffic are accurate. Simulation, urgently need to accurately and effectively control the mass flow of particles, form an effective closed-loop control system particle loading device and small flow vectors to s...

Problems solved by technology

In addition, in the prior art, the test bench and the cooling water pump room are usually set up in different areas, which is inconvenient for centralized management and operation

[0004] The process gas system is an important supporting system of the engine test bench. It configures the operating gas source for the control valve in the regulating gas circuit of the sub-systems such as the intake total pressure simulation system and the injection system. , each subsystem is decentralized and not systematic, resulting in complex operation process and slow response speed
