[25] [26] Loss of control may occur if one wing tip stalls in ground effect. During certification testing of the Gulfstream G650 business jet the test aircraft rotated to an angle beyond the predicted IGE stalling angle. The over-rotation caused one wing-tip to stall and an uncommanded roll, which overpowered the lateral controls, leading to ...
Two Dassault Mirage G prototypes, the upper one with wings swept A Grumman F-14 Tomcat testing an unusual asymmetric wing configuration, a possible in-flight failure case, showing one wing at minimum sweep and one at maximum sweep. A variable-sweep wing, colloquially known as a "swing wing", is an airplane wing, or set of wings, that may be ...
Any disturbance of the angle of attack on one wing will cause the whole wing to roll spontaneously and continuously. [1] [3] When the angle of attack on the wing of an aircraft reaches the stalling angle the aircraft is at risk of autorotation. This will eventually develop into a spin if the pilot does not take corrective action.
The aerodynamic center of an airfoil is usually close to 25% of the chord behind the leading edge of the airfoil. When making tests on a model airfoil, such as in a wind-tunnel, if the force sensor is not aligned with the quarter-chord of the airfoil, but offset by a distance x, the pitching moment about the quarter-chord point, / is given by
A blended-wing plane would have a much wider cabin than a traditional tube-and-wing design, meaning the rows could be more than a dozen people long.
A stall does not mean that the engine(s) have stopped working, or that the aircraft has stopped moving—the effect is the same even in an unpowered glider aircraft. Vectored thrust in aircraft is used to maintain altitude or controlled flight with wings stalled by replacing lost wing lift with engine or propeller thrust , thereby giving rise ...
Dihedral effect is not caused by yaw rate, nor by the rate of sideslip change. Since dihedral effect is noticed by pilots when "rudder is applied", many pilots and other near-experts explain that the rolling moment is caused by one wing moving more quickly through the air and one wing less quickly.
