Taranenko V. Modified panel the method for calculation aerodynamic characteristics of wing final span at non-stationary movement nearby ground

object: process of interaction of the mechanized wing moving accelerated or retarded nearby ground, with the environment; purpose: modification a panel method of research flow structures and the aerodynamic forces arising at non-stationary movement of wing nearby ground, for case multiply connected space, concerning to wings with mechanization; methods: the panel method, the method of discrete vortices and the finite volume method; results: panel method is modified for the calculation of aerodynamic characteristics of the mechanized wings on conditions of take-off and landing aircraft, and also developed software; novelty: a the panel method is modified, in which unknown intensity of a lifting vortex surface is approximated bicubic by a spline that provides a continuity of pressure in all flow field and results in reduction of quantity of unknown in a final system of linear algebraic equations; offered modification allows to expand capabilities of a computational method for a case space multilinked, concerning to mechanized wing which move accelerated or retarded nearby ground; for the first time by numerical calculation it is established, that nearby ground decreases influence on the additive to lift which acts on wing profile, conditions by accelerated or retarded motion of a wing; numerical calculation refinement relation of the additive to lift operational on a wing, conditions by effect non-stationary movement, from value of acceleration or retardation; field: aircraft construction.
