AERODYNAMIC-SHAPE BODY, AIRCRAFT AND METHOD TO REDUCE FRICTION LOSSES

摘要

FIELD: transport. ^ SUBSTANCE: set of inventions relates to aerodynamics. Aerodynamic-shape body comprises control channels 1 with control section 5 that comprises inlet part 2 and outlet part 3. Note here that inner wall of control part 5 allows effective cross section for flow to automatically decrease thanks to formation of turbulent vortices on inner wall of control part 5 on increasing pressure difference between inlet part 2 and outlet 3 of control section 5. Proposed aircraft is constructed in the form of aerodynamic-shape body. Proposed method intended for reducing friction losses on surface 8 consists in that fluid medium flow automatically controlled by control channels 1 is withdrawn from surface 8 by sucking boundary layer off through control channels 1 using sole suction chamber so that aforesaid boundary layer on surface 8 is stably maintained in laminar mode. ^ EFFECT: optimised lift distribution. ^ 15 cl, 6 dwg
