METHOD FOR HYPERSONIC AIRCRAFT (HAC) MODEL ROLL ANGLE GENERATION OF A CONTROL SIGNAL FOR CONTROLLING THE AERODYNAMIC IDENTITY ACCORDING TO THE REYNOLDS NUMBERS OF THE FLIGHT TRAJECTORIES OF THE MODEL AND THE FULL-SCALE AIRCRAFT IN CONDUCTING ADVANCED FLIGHT TESTS OF AERODYNAMIC CHARACTERISTICS

摘要

FIELD: aircraft engineering.;SUBSTANCE: invention relates to a method for hypersonic aircraft (HAC) model roll angle generation of a control signal. To form a control signal for controlling the aerodynamic identity according to the Reynolds numbers of the flight trajectories of the model and the full-scale HAC in conducting advanced flight tests of aerodynamic characteristics, the altitude, flight speed, attack and roll angles, temperature, pressure, atmospheric density are measured, high-speed computed roll angle is calculated in a certain way, the calculated value is corrected taking into account a pre-calculated signal calculated in a certain way, required corrected roll angle value, necessary for transient process for reaching the trajectory of the model is found.;EFFECT: higher accuracy of identifying aerodynamic characteristics according to the flight tests results is provided.;1 cl, 5 dwg
