Abstract

The invention discloses a dynamic flow field measuring method, system and equipment. The dynamic flow field measuring equipment comprises a pressure measuring main body, wherein a head of the pressure measuring main body is provided with a probe head, a tail of the pressure measuring main body is provided with a socket, and the pressure measuring main body is internally provided with a pressure sensor respectively connected with the probe head and the socket. According to the dynamic flow field measuring equipment, the wind tunnel gust test direction field can be accurately measured in real time, the interface is standard, and the dynamic flow field measuring equipment is plug-and-play.

Description

technical field [0001] The invention relates to the technical field of flow field measurement, in particular to a dynamic flow field measurement system. It also relates to a dynamic flow field measurement method. It also relates to a dynamic flow field measuring device. Background technique [0002] Aircraft flying in the atmosphere are often disturbed by gusts (or gusts) and atmospheric turbulence, which form additional aerodynamic loads and wing elastic mode vibrations, causing aircraft turbulence, and eventually causing fatigue damage or even damage. [0003] The internationally accepted civil aircraft airworthiness regulations clearly stipulate that new civil passenger aircraft must pass the gust response test before they can be delivered for use. Reasonable determination of gust loads and mitigation of gust effects are of great significance to ensure aircraft flight safety. In order to reduce the influence of gusts, active control technology is usually used to control...
