Wireless pressure measuring device and pressure measuring method for high speed wind tunnel rotation model

Abstract

The invention discloses a wireless pressure measuring device and pressure measuring method for a high speed wind tunnel rotating model. The device comprises a pressure measuring module, a power supplymodule and a zero setting switch. When a model test is performed in a high speed wind tunnel, the pressure measuring module, the power supply module and a signal receiving module are fixedly arrangedin the inner portion of the rotating model, a module switch is turned on, a collecting instruction is sent to the pressure measuring module by a control computer connected to a wireless signal transmitting device; after the test is completed, an end instruction is sent again, and the collected pressure data is automatically saved into a data storage device in the module after the end instructionis received. The wireless pressure measuring device and pressure measuring method for the high speed wind tunnel rotating model have the advantages that the problem is solved that the collection of related data of the rotating model test in the high speed wind tunnel is difficult, the wireless signal transmitting technology takes the place of the wired physical connection between the control equipment and the measuring equipment, thereby greatly simplifying the measurement system, saving the test space, the comprehensive performance is more stable, and the application prospect is very wide.

Description

technical field [0001] The invention belongs to the technical field of high-speed wind tunnel test equipment, in particular to a wireless pressure measurement device and a pressure measurement method for a high-speed wind tunnel rotation model. Background technique [0002] With the development of modern high-speed fighter planes and tactical missiles, relevant high-speed wind tunnel tests are increasingly indispensable, especially high-speed wind tunnel tests for tactical missiles. Due to factors such as aerodynamic layout, most tactical missiles rotate around their own body axis during actual flight. In order to restore the actual flight state of the missile as much as possible in the wind tunnel test, a rotating missile model is generally used for related experiments. However, for the rotating model, the measurement of relevant physical quantities in the test becomes very difficult, and the entire experimental section of the high-speed wind tunnel is closed during operati...
