AEROHYDRODYNAMIC BODY WITH LOW HEAD RESISTANCE AND ENHANCED COANDamp;Abreve; EFFECT

摘要

The invention relates to an aerohydrodynamic body with low head resistance and enhanced Coandă effect, meant for air vehicles, as well as marine and river ships achieving low resistance to motion, while interfering with the flow of the fluid (air or water) by reducing turbulence. The body claimed by the invention comprises a central body (1) and a median body (2), supported by some struts (3) maintaining the space between the bodies, thereby forming a channel (a) adapted to the cruising speed of the air or naval vehicle, which transmits the low upstream pressure to the terminal part of the body, where a negative pressure suction area is formed, the fluid stream, previously deflected towards the body by the Coandă effect generated on the divergently curved terminal surface thereof, being sucked by means of the channel (a), the constructive shape thereof allowing the deviation of the fluid stream due to the Coandă effect to overlap the suction caused by the negative pressure area in the terminal part of the body, resulting in the enhancement of the Coandă effect.
