Embodiment Construction

[0019] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0020] as attached figure 1 As shown, the thermodynamics-oriented parameter measurement comprehensive test system includes the system main module 1, the control module 3 and the measurement module 2. The main module of the system uses the ducted fan 4 as the air source, the turbine 12 as the power device, relies on the PTC heating ceramic 7 and the cylinder 8 as the heating system and the displacement system respectively, supplemented by differential pressure sensors 13 and 20, pressure sensors 14, 17 and 19, temperature sensors 15, 16 and 21, displacement sensor 22, rotational speed sensor 18 etc. are made up of ten different sensors altogether. When working, first use the relevant control program to provide a specific PWM signal to the electric regulator board 31 of the ducted fan 4 through the PC terminal, so that the ducted fan 4 starts to run...

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.
