Abstract:
Gel propellant is a non-Newtonian viscoelastic fluid with high viscosity and pressure thixotropic characteristics. Coriolis mass flowmeter is used in the engine actual test to measure the gel propellant mass flow in the actual piping. According to the pressure thixotropic features of gel propellant, an in-depth research of gel flowmeter calibration was conducted in Xi'an Aerospace Measurement and Testing Institute. Based on the structure of active piston liquid flow standard device, a gel flowmeter calibration device was designed by adding a pressure boost/pressure relief device and online density meter. The device can fully simulate the actual working conditions of gel flowmeter to achieve the simulation calibration of gel propellant flowmeter, and thereby improve the measuring accuracy of the transient gel flow. This gel flow calibration device has features of stable flow, perfect reproducibility and wide measurement range. Its mass flow measurement range is 19.44～3 611 g/s, which can fully meet the requirements of the gel propellant mass flow measurement of aerospace engines in real hot commissioning and altitude simulation test. The research laid a foundation for the subsequent function extension of the device.
