Basic Principles of Flight Test Instrumentation Engineering Volume 1 Issue 2(Introduction Generale aux Principles de Base de l'Instrumentation des Essais en Vol)

摘要

Flight tests Volume 1 of the AG 300 series on 'Flight Test Instrumentation' givesa general introduction to the basic principles of flight test instrumentation. First published in 1974, it has been used extensively as an introduction for instrumentation courses and symposia, as well as being a reference work on the desk of most flight test and instrumentation engineers. In this second edition, a test stem is considered to include both the data collection and data processing systems. To obtain an optimal data flow, the overall design of these two subsystems must be carefully matched; the detail development and the operation may have to be done by separate groups of specialists. The main emphasis is on the large automated instrumentation systems used for the initial flight testing of modern military and civil aircraft. This is done because there, many of the problems, which are discussed here, are more critical. It does not imply, however, that smaller systems with manual data processing are no longer used. In general, the systems should be designed to provide the required results at the lowest possible cost. For many tests which require only a few parameters, relatively simple systems are justified, especially if no complex equipment is available to the user. Although many of the aspects discussed in this volume apply to both small and large systems, aspects of the smaller systems are mentioned only when they are of special interest.
