Abstract
Способ измерения параметров потока на выходе из протоков моделей летательных аппаратов, в котором модель с протоками, имитирующими каналы силовой установки, устанавливают в аэродинамической трубе с гребенкой приемников полных и статических давлений, передают измеряемые давления к преобразователям давления, электрические выходы которых присоединяют к измерительной аппаратуре, отличающийся тем, что приемники давлений подсоединяют встык к преобразователям давления, которые монтируют в одном корпусе с электронным коммутатором в хвостовой части модели, электрические выходы преобразователей подключают к электронному коммутатору, электрический сигнал, от которого передают на измерительную аппаратуру по кабелю, расположенному внутри державки модели (не снимая обтекателя державки) и проводят измерения давлений в одном эксперименте с весовыми измерениями аэродинамических сил и моментов, действующих на модель.A method for measuring flow parameters at the exit from the ducts of aircraft models, in which a model with ducts simulating the power plant channels is installed in a wind tunnel with a comb of full and static pressure receivers, the measured pressures are transmitted to pressure transducers, the electrical outputs of which are connected to the measuring equipment, characterized in that the pressure receivers are connected end-to-end to pressure transducers, which are mounted in one housing with an electronic switch in the tail part of the model, the electrical outputs of the transducers are connected to an electronic switch, the electrical signal from which is transmitted to the measuring equipment via a cable located inside the model holder (without removing the fairing of the holder) and pressure measurements are carried out in one experiment with weight measurements of aerodynamic forces and moments acting on the model.
