The Onboard Data-Acquisition System of Research Aircraft for Studying Atmospheric Processes

详细

The onboard data-acquisition system for the new-generation Yak-42D Roshydromet research aircraft is described. The research aircraft is intended for investigating the atmosphere and the underlying surface. The large quantity of scientific equipment installed onboard requires that the tasks of acquisition, synchronization, transmission, and storage of aircraft observation data be performed. The onboard measuring and computing system developed for the research aircraft and the local computer network are described. The solution to the problem of synchronizing the data of high-frequency measurements is presented. The possibilities of using the local network for integrating the measurement systems on board the research aircraft are shown. The principles of organization of a unified data-acquisition system can be used to build measuring systems for any class of mobile laboratory.
