Embodiment Construction
[0034] This embodiment is a pressure measuring mechanism used to determine the direction of incoming flow.
[0035]This embodiment includes a beam 1, a bracket 2, and 20 pressure measuring cones 3, and a rotating shaft 5 matching the 20 pressure measuring cones 3, an angle sensor 4, an eccentric ball bearing 8, a gland 6, a total pressure pipe 9, a static pressure Tube 10 and hollow pin 11.
[0036] Both ends of the beam 1 are fixed on the top of the bracket 2 . A plurality of pressure measuring cones 3 are installed on the upper surface of the beam 1, the number of the pressure measuring cones is determined according to the range and measurement accuracy of the test model wake area, so that the test model wake area is between the pressure measuring cones at the most ends. In this embodiment, the width of the wake area of the test model is 300mm, and the number of pressure measuring cones is 20. Each of the pressure measuring cones 3 is installed above the beam 1 through e...
