It is analysed the basic schemes and algorithms of work pulse HLA. The periodic operating mode with reception of a useful signal in a steady mode of a direct current and a cooling mode is selected at frequency of interrogation of 500 Hz. The developed basic scheme of the block of gauges on the basis of microprocessor ADUC834BS as the managing director and a computer. The made model samples also are received experimental characteristics of cooling of the gauge at different speeds and gas temperatures. The mathematical model теплоотдачи the difficult gauge in a gas stream and obtain private decisions is formulated. Conditions on border are defined by the decision of a problem of a flow in the environment of FEMLAB Product Description popup.authors Асланов П.В. Болонов М.І. Надтока О.М. Ростовська Д.О.
