Force measurement, pressure measurement, angle measurement and vibration inhibition multi-functional model

Abstract

The invention relates to a force measurement, pressure measurement, angle measurement and vibration inhibition multi-functional model. The model comprises an airplane model, angle measurement equipment, a scanning valve, a scale, a vibration inhibition device and a tail sting, wherein one end of the scale is connected with the airplane model, the other end of the scale is connected with the tail sting through the vibration inhibition device, wings of the airplane model are provided with pressure measurement cross sections, a pressure measurement pipeline is led to a belly cavity of the airplane model and is then led into an internal portion of a head of the airplane model to connect with the scanning valve, a scanning valve cable is led out of the airplane model through a scale center holeand a tail sting center hole to realize wing surface pressure measurement, the angle measurement equipment is arranged in the head of the airplane model, the cable is led out through the scale centerhole and the tail sting center hole, model attitude angle measurement is realized, and model vibration can be effectively inhibited through the vibration inhibition device. The model is advantaged inthat multiple types of measurement components are reasonably designed and distributed, force measurement, pressure measurement and angle measurement are synchronously carried out, the structure is simple, and the model is convenient to dismount.

Description

technical field [0001] The invention relates to wind tunnel test technology, in particular to a multifunctional model for force measurement, pressure measurement, angle measurement and vibration suppression. Background technique [0002] The wind tunnel model is the key equipment for wind tunnel experiments. Conventional dynamometric phantoms are used for dynamometric test studies, or manometry phantoms are used for manometric test studies. At present, a test project often has various requirements, that is, to measure force and pressure, and may also require consideration of other test studies. [0003] If models with different functions are designed for different research needs, the cost of model processing is bound to be high. And in a test project, different models are used for research, and because the replacement of the model will cause a waste of time in occupying the hole. Therefore, models with single functions such as force measurement or pressure measurement can...

[0003] If models with different functions are designed for different research needs, the cost of model processing is bound to be high

And in a test project, different models are used for research, and because the replacement of the model will cause a waste of time in occupying the hole

Therefore, models with single functions such as force measurement or pressure measurement can no longer meet the requirements of model cost economy and test efficiency.
