1. This permits a lower downwash velocity for a given amount of thrust. 2. However, the downwash is purely a function of the circulation only. 3. Essentially, the helicopter descends into its own downwash . 4. They were concerned that the strong propeller downwash would make it difficult to operate. 5. Thomasson also forecasts inefficiencies from rotor downwash on the large conventional wing and bulky fuselage. 6. The result is a region of downwash behind the aircraft, between the two vortices. 7. The model has the capability to calculate : the rise of downwash effects of buildings. 8. The downwash at any given station is a function of the entire shed vortex system. 9. The trailing wingtip vortices are responsible for the component of the downwash which creates induced drag. 10. :As pointed out above, a plane's downwash spreads outward and dissipates rapidly.
