Digitalization Research and Application of Airborne Transducer for Pilotless Aircraft

Discusses and surveys the possible ways of the developing airborne digital air data transducers of several types of pilotless aircraft, and the technical feasibility and realizability is also fully proved. Then a miniature digital altitude-airspeed measurement system is presented. This measurement system is composed of miniature silicon pressure sensors and a microcomputer, and is shown to be able to satisfy the requirement of a digital autopilot equipped on a type of small unmanned aircraft under development. Since this measurement system manifests a high Performance-cost ratio,it is expected to have wide range of applications for other cost-effective unmanned airvehicles. The measurement of the altitude and altitude difference of a sea-scanning target performing very low altitude flight is a typical as well as a unique application of this measurement system.
