DYNAMIC ERRORS IN THE SYSTEM OF MEASURING LOW HELICOPTER AIRSPEED

摘要

We consider a structural-functional scheme of a system for measuring low helicopter airspeed on the basis of a stationary multichannel aerometric tube and jet-convective measuring channels. We analyze the reasons and present mathematical models of inherent and forced dynamic errors of the system channels under determinate and random actions. We also give a simulation model and results of the computer experiment that provide support for the validity of the models proposed.
