angle of attack

The position of an airplane as it moves through the air. What is our angle of attack, Captain? Are we going to be able to land this plane as planned?

The velocity vectors shown in figure 3 are for the wing at an angle of attack of 20[degrees] and Reynolds number 100.
However, at an angle of attack of 90[degrees] the position with the thumb adducted presented the highest value of resultant force coefficient.
Flight tests with this F-18 Harv (High Alpha Research Vehicle) from 1987 to 1996 included Herbst turns and the use of an offensive descending spiral inside the flight path of a tightly turning conventional opponent, tracking the target for up to ten seconds and a 60[degrees] angle of attack.
With drive height, angle of attack, and good shoes on the one-way plow figured out and perfectly in place, the good operator only has to hit the road.
It is clear that case (2) will develop the highest recovered power, that's to say at WT position of 260 mm, rotor (1) air angle of attack 12[degrees] guide vanes angle (A=30[degrees], B=120[degrees]) will be the optimum parameters values for the present cooling tower--WT energy system.
opt] stand for air density, wind speed, sail projected area, camber ratio of sail, ratio of sail, and the optimum angle of attack in sequence.
Equation (5) ensures that the large angle of attack does not appear when the launch vehicle flies through high dynamic pressure areas.
It changes the airflow aft of the wings, deflecting it downward, which causes increased downwash over the tail, increasing its angle of attack.
Normalized angle of attack systems, on the other hand, are designed to provide consistent AoA indications that are not related to atmospheric conditions and the aircraft configuration, including loading.
The angle of attack was low, causing the aircraft to have inadequate lift for wingborne flight at the time the thrust was vectored completely aft.
The simulation was determined by these aerodynamic parameters of the aircraft: the dependence of the lift force coefficient on the coefficient of drag force, the dependence of the lift force coefficient on the wing's angle of attack, and the dependence of the quality factor on the angle of attack of the wing (Fig.
Angle Of Attack made all to win over course and distance on a standard to slow surface nine days ago and he looks to have a particularly solid chance of doing so again this afternoon.
A number of steering strategies are possible for solid-axle wheelsets, but the perfect steering can be achieved if the angle of attack for two wheelsets can be controlled to be equal, and the bogie is in line with the track on curves (Iwnicki, 2006).
The other two parameters which should be taken into account are dynamics of tail flexion change in downbeat and dynamics of the change in angle of attack in upbeat.
