AEROMECHANICAL METHOD OF MEASUREMENT OF AIR-SPEED PARAMETERS OF FLIGHT TRAJECTORY AND DEVICE FOR ITS IMPLEMENTATION

摘要

FIELD: physics, measurement.;SUBSTANCE: invention is related to the field of measuring equipment and may find application, in particular, in measurement of air-speed parameters of airplane flight trajectory, in particular, such as velocity head, angle of attack, coefficient of aerodynamic lift, airplane mass, position of airplane center of gravity and so on. Device for measurement of air-speed parameters of flight trajectory consists of pressure difference sensors group, group of functional transducers, amplifiers, group of indicators. Device operation consists in processing of voltages of output signals from pressure difference sensor, which are installed in appropriate specially selected points of airplane aerodynamic surface. Measured signals from pressure difference sensors are transformed with the help of device functional transducers, and by preset functional dependences values of output voltages of functional transducers are calculated, which are proportional to desired air-speed parameters of flight trajectory.;EFFECT: higher accuracy of measurement.;2 cl, 4 dwg
