| 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.
