Parameter measurement integration test system facing heat flow dynamics and test method thereof

Abstract

The invention relates to a parameter measurement integration test system facing heat flow dynamics and a test method thereof. The system comprises a system main body module, a measurement module and a control module. The test system takes a ducted fan as a gas source and a turbine as a power apparatus. PTC heating ceramic and an air cylinder are served as a heating system and a displacement system respectively. A differential pressure sensor, a pressure sensor, a temperature sensor, a displacement sensor and a rotating speed sensor are used to assist to simulate measurement of some important parameters (a flow, pressure, a temperature, a displacement, a rotating speed and the like) during aircraft engine operation. Through adjusting a valve opening degree and controlling an input signal, parameter adjusting is realized. The system can visually display a heat flow dynamics basic principle, covers comprehensive measurement parameters and possesses characteristics of a compact structure, low cost, high operability and the like.

Description

technical field [0001] The invention relates to a thermal fluid dynamics-oriented parameter measurement comprehensive test system, which belongs to the field of test and control. Background technique [0002] The above-mentioned temperature, pressure, and displacement sensors are widely used in the measurement of relevant parameters of fluids, but judging from the related products launched by the current international mainstream test instrument manufacturers Brilliant Company or ATPIO Company, such as XB-9E and XORTS These devices can only realize the measurement of a single or a few parameters, and there is no test system for comprehensive measurement simulation and control simulation of the relevant parameters of the airflow during the operation of the aero-engine, and the above-mentioned systems are complex in structure, cumbersome in operation, and expensive And other characteristics, it is difficult to meet the needs of specific customers in the market.
