Transputer Based Static Data Acquisition Systems at DNW

摘要

An important part of wind tunnel measurements consists of the acquisition ofstatic signals. Static in this context refers to the slowly varying signals representing the steady conditions during a measurement. Recently the German-Dutch Wind Tunnel DNW has replaced its old static data acquisition systems. The data acquisition hardware for two new systems has been delivered by the Dutch National Aerospace Laboratory NLR. The channel hardware is based on the proven concept of the NLR conditioning unit (1). This unit was selected by DNW because of its excellent analog characteristics. The unit delivered to DNW is a further development of the generation of units in use at a number of wind tunnels (e.g. European Transonic Wind Tunnel ETW, Germany).
