Application of PC Based, Real-Time, Data-Acquisition System in Rotorcraft Wind-Tunnel Testing
Abstract
Data have been acquired for a rotorcraft test in the Langley Transonic Dynamics Tunnel using a desktop-data acquisition system. The system, which consists of an IBM Personal Computer AT (PC-AT) and an Omega Engineering OM-900 stand-alone interface system, is well suited for acquiring high-speed data on a limited number of channels. The data-acquisition system and the interrupt-driven software, which provides the capability for near real-time, cyclic data acquisition as well as data storage and display, are described herein. Keywords: Data-acquisition systems; Personal computers; Helicopters; Model rotor testing. (JHD)
