Abstract

The paper present the results of work on measurement system dedicated to hardware used during wind tunnel tests, especially to servomechanisms. These devices could be applied to set specific position of control surface. Proposed system would ensure continuous monitoring of servo-rotor position and servo-motor temperature and would avoid uncontrolled change of control surface position. The application designed to monitor the operating status of the servomechanism was prepared in the LabVIEW software and was implemented on the myRIO platform. Developed test rig allow to register time histories of servo-rotor position and temperature during for different values of applied load. In the paper, test methodology were also presented. Experimental studies show that before wind tunnel tests, selected servomechanism should be tested in terms of maintaining the parameters declared by the manufacturer, especially during continuous operation. Developed measurement system can be used during wind tunnel tests, as well as only for servo-mechanism parameter testing.

Highlights

  • Wind and water tunnel measurements play an important role in aircraft research programmes, due to the cost minimalization and time saving (Barlow et al 1999, Operations and Maintenance Manual 2012)

  • In the paper we proposed the use of servomechanism with dedicated measurement system to ensure continuous monitoring of servo-rotor position and servo-motor temperature

  • We proposed measurement system dedicated to hardware used during wind tunnel tests, especially to servomechanisms

Summary

Introduction

Wind and water tunnel measurements play an important role in aircraft research programmes, due to the cost minimalization and time saving (Barlow et al 1999, Operations and Maintenance Manual 2012). Developed measurement system can be used during wind tunnel tests, as well as only for servo-mechanism parameter testing. To monitor the above-mentioned parameters, measurement system with potentiometer and temperature sensor were designed and manufactured (Günter et al 2006).
