Abstract

The invention discloses an intelligent false support rod device for a high-speed wind tunnel. The device comprises a displacement sensor, a transmission mechanism, a driver, a measurement and controlcable for connecting the displacement sensor, the transmission mechanism and the driver, and a subsystem for controlling the displacement sensor, the transmission mechanism and the driver, the displacement sensor is mounted at the head of the false tail support rod to monitor a gap between the false tail support rod and the model; and the transmission mechanism and the driver are installed in an inner cavity of the straight joint, and the driver drives the transmission mechanism to drive the false tail supporting rod to move relative to the model. The subsystem is connected with a measurementand control system of the high-speed wind tunnel and shares one computer with the measurement and control system of the high-speed wind tunnel. The device can realize following motion of the false tail support rod relative to the model, avoids collision between the model and the false tail support rod, and obtains more accurate tail support interference quantity under a larger attack angle; and the false tail support rod can be controlled to move according to an instruction, a gap between the false tail support rod and the model is changed, and the influence of the gap on support interferenceis studied.

Description

technical field

[0001] The invention belongs to the technical field of high-speed wind tunnel tests, and in particular relates to an intelligent false support rod device used in high-speed wind tunnels. Background technique

[0002] In high-speed wind tunnel tests, support interference has been a long-standing problem. In order to obtain accurate and reliable support interference data through experimental means, a special support interference wind tunnel test is required. The support interference wind tunnel test needs to design a set of auxiliary support devices and a set of dummy struts.

[0003] Usually, the support interference of the tail support in the high-speed wind tunnel is the least, so the main support form in the high-speed wind tunnel is generally the tail support. The support interference test device of tail support uses auxiliary supports such as abdominal blade support, strip support, wingtip double support, vertical tail support, etc. The secondary interfe...
