downwash การใช้

• This permits a lower downwash velocity for a given amount of thrust.
• However, the downwash is purely a function of the circulation only.
• Essentially, the helicopter descends into its own downwash.
• They were concerned that the strong propeller downwash would make it difficult to operate.
• Thomasson also forecasts inefficiencies from rotor downwash on the large conventional wing and bulky fuselage.
• The result is a region of downwash behind the aircraft, between the two vortices.
• The model has the capability to calculate : the rise of downwash effects of buildings.
• The downwash at any given station is a function of the entire shed vortex system.
• The trailing wingtip vortices are responsible for the component of the downwash which creates induced drag.
• :As pointed out above, a plane's downwash spreads outward and dissipates rapidly.
• When delivering soldiers, the Hawk swivels its rotors to direct downwash away from the jump doors.
• The model also includes algorithms for handling the effect of downwash by nearby buildings in the path of the pollution plumes.
• Yaw was controlled with a " Spin Vane " that used downwash from the rotor to pivot the aircraft with foot pedals.
• This creates a boundary layer which causes the downwash from the main rotor to hug the tail boom according to the Coand
  effect.
• This sideways influence ( upwash on the outboard, downwash on the inboard ) is the key to the lifting-line theory.
• The V-22 has a maximum rotor downwash speed above 80 knots, more than the 64 knots lower limit of a hurricane.
• Wingtip vortices are associated with induced drag, the imparting of downwash, and are a fundamental consequence of three-dimensional lift generation.
• The Fw-Rochen would have achieved forward flight by vectoring the downwash from the propellers rearward through a series of louvers below them.
• The curved tube allows the tail to be located higher, out of the wing's downwash, especially when the flaps are extended.
• :: : : : When the plane's trailing downwash of air pressure has transferred its energy, the downwash seizes to exist.
