METHOD FOR CREATION OF ADDITIONAL REACTIVE JET AND LOWERING WAVE IMPEDANCE FOR MOVABLE, FOR INSTANCE LAUNCHED, BODY IN FORM OF MISSILE WITH PREDOMINANTLY OGIVAL OR SHARP-POINTED NOSE AND MISSILE-SHAPED BODY WITH PREDOMINANTLY OGIVAL OR SHARP-POINTED NOSE

摘要

FIELD: transport.SUBSTANCE: invention relates to aerodynamics of rotation bodies. Axisymmetric rotation body (ARB) (shell shape) with ogival or sharp-pointed nose contains additional airfoil (AF) (fixed, all-movable, rotary with different rotation axes, slotted, all-extendible, adaptive) in calibre, sub-calibre, over-calibre position. Between ARB and AF, two confusors are created with two channels distributed along ring of confusor, after contactor, closed ring diffuser and closed ring channel with constant in length cross-section are formed.EFFECT: invention permits to create additional reactive jet, to lower wave impedance.20 cl, 6 dwg
