FIELD: physics; measuring.
SUBSTANCE: invention concerns to technics of determination of parametres of motion and angular standing of flying machines. At flight trials of a hypersonic flying machine (HFM) measure pressure by data units of the aerial pressure erected in discrete points on spherical nose of the HFM with the given steps in dilatational and lateral planes. Spend a complex of measuring of pressure of an incident flow by means of pressure data units, and linear accelerations and angular velocities - by means of the three-axial data unit of linear accelerations and angular velocities (TADLAAV). Perform evaluations on the onboard computer of angles of attack and slide under indications TADLAAV, using known kinematic relations. Simultaneously in the onboard computer calculate values of angles of attack and slide under formulas of quadratic approximation of indications of each group on three data units of pressure from blanket number in each plane of measuring. From the gained quantities reject the underload and peak values of angles; find a desired value of each of corners as an average arithmetic of the remained values. Spot terrain clearance values of differences between the design values of corners gained on measuring of TADLAAV, and the values of corners gained on measuring of data units of pressure. Compare terrain clearance values of differences to in advance given quantities. Depending on effects of comparison fix as target signals of value of the corners, calculated on measuring TADLAAV or on measuring of data units, and transmit them for formation of signals of HFM guidance and for definition of a vector of force of traction of the drive. Processing of observed data perform practically in the linear range with a small step between drainage holes. The invention provides the raised accuracy of definition of angles of attack and slide.
EFFECT: increase of accuracy of determination of angles of attack and slide.
