Title:
COMPOSITE FIVE-HOLE PRESSURE-TEMPERATURE PROBE
Document Type and Number:
WIPO Patent Application WO/2021/174681
Kind Code:
A1
Abstract:
A composite five-hole pressure-temperature probe, comprising one total temperature thermocouple (11), five pressure-measuring tubes (6-10), four static pressure-measuring tubes (13-16) and four static temperature thermocouples (17-20) that are disposed inside a probe rod body (4), wherein the front end of the probe rod body (4) is a static parameter section (3), the rear end of the probe rod body (4) is a lead-out section (5), and a transition section (2) connects a pressure-measuring head (1) and the static parameter section (3); detection ends of the total temperature thermocouple (11) and the pressure-measuring tubes (6-10) are disposed the end part of the pressure-measuring head (1); and detection ends of the static pressure-measuring tubes (13-16) and the static temperature thermocouples (17-20) are disposed on the side wall of the static parameter section (3), and all of the pressure-measuring tubes (6-10,13-16) and thermocouples (11,17-20) extend out from the lead-out section. The composite five-hole pressure-temperature probe may measure the total temperature, static temperature, total pressure, static pressure, Mach number, three-dimensional flow velocity, airflow deflection angle and pitch angle, and other pneumatic parameters under the conditions of transonic flow and supersonic flow at the same time and in the same place, which effectively reduces the interference of the probe on a flow field and achieves accurate measurement.
