Aerospace Instrument-Making Annotation << Back Measuring and computing systems for determination of low airspeeds of helicopter A.A. Porunov, V.V. Soldatkin, V.M. Soldatkin In this paper, we discuss some principles of construction, algorithms for data processing, causes of appearance of instrumental errors and realization of their adjustment in systems for measuring the low airspeeds with use of the fixed multi-channel receiver and jet-convective measuring channels. Based on the VIMI method and the Lunberger’s observer, we consider also some features of construction and algorithms for functioning the aeromechanical system used in calculations of airspeed vector components. Also evaluated is the precision of the integrated system’s measurements.
