Abstract: FIELD: experimental aerodynamics. SUBSTANCE: method establishing aerodynamic corrections to readings of pitot-static tubes consists in establishment of corrections relating readings of airborne pitot-static tubes to parameters of undisturbed flow and of dependencies for determination of angle of attack and effect of angle of sideslip by test results in wind tunnels. Method is realized by way of stage-by-stage multiple tests of models of aircraft with models of pitot-static tubes and transmitters of local angles of deviation of flow, tests of full- scale pitot-static tube and its models conducted in wind tunnel. Position of pitot-static tube on aircraft is determined by results of these tests and tests of ventilated model of aircraft. Local parameters of flow close to side of model of aircraft in point of location of pitot-static tube as well as difference in corrections of full-scale pitot-static tube and its models are found with use of corrections to readings of model of pitot-static tube in isolated form. In final form corrections to full-scale pitot-static tubes mounted on aircraft are established by summation of corrections of models of pitot-static tubes in mix of model of aircraft with difference between corrections of full- scale pitot-static tube and its model in isolated form with due account of local parameters of flow close to side of aircraft. Angular coefficients of full-scale pitot-static tube in mix of aircraft are determined by dependencies of angular coefficients of isolated full-scale pitot-static tube for local angles of attack with allowance for local parameters of flow. EFFECT: determination of corrections to readings of airborne pitot-static tubes by results of tests in wind tunnel when possibility for their establishment in flight does not exist. 8 dwg
