- Abstract:
- In order to obtain the saueer-shaped lifting body’s flow filed fealures and development law, theeomputational fluid dynamies method was taken to simulate the saucer-shaped lifing body’s flow field, as wellas its stalling characteristies. "The simulation was validated by the wind tunnel experiments. The simulation re.sults show that the saucer-shaped lifing body’s llow field has a steady vortex structure , bring a signifieant vor.tex lift, which inereases with the inereasing of altack angle. The vortex lift to tolal lift ratio is 8%6 when the attack angle is 4°, and the ratio is 30%6 when the allack angle is 40°. The stalling angle of the saueer-shapedlifing body is 40°, which is beller than the conventional aireraft.
