| Abstract: | The dynamic flow behavior during pitching maneuver is related to the dynamic wash effect induced by the motion of the object. The dynamic hysteresis effect dueto the pivot position moving back is similar to that due to the increase in pitching rate.During the aircraft pitching up, a strong dynamic hysteresis appears on the canard but another dynamic "advanced" effect occurs on the horizontal tail. So the stall on the canardwould occur at a higher angle of attack but the stall on the tail would appear at a lower an, gle of attack. The dynamic hysteresis is also affected by the "heredity" effect relating tothe initial conditions besides the dynamic wash effect. |
