To plunge into mire or snow so as not to be able to get on; to set; to fix; as, to stall a cart.
To be set, as in mire or snow; to stick fast.
Loss of enough lifting power to hold the plane aloft; may be caused by low speed or other factors.
An aerodynamic condition in which the airflow over the upper surface of the wing is disrupted by excessive angle of attack, sharply reducing the amount of lift produced.
A loss of lift by an aircraft or airfoil resulting from insufficient air speed or excessive angle of attack
The condition of an aircraft when excessive angle of attack causes the disruption of airflow and is accompanied by loss of lift
any flying model will stall when the flying speed gets too low and the necessary amount of lift needed to hold the model in the air is lost. Getting to know your model's stalling speed by reducing throttle and applying up elevator at the same time is a very good idea, but don't practice too close to the ground if you want to avoid using the plastic bag.
When drag and gravity overcome the forces of lift and thrust on any aircraft, the aircraft will stall. Typically a stall occurs when the angle of attack becomes too steep. An aerodynamic stall has nothing to do with an engine quitting. Report this Word See also: Angle of Attack Added by: mkranitz
Purely an aerodynamic condition – nothing to do with engine operation. Occurs when lift-producing airflow over the wings is disrupted or lost because angle of wings to airflow (angle of attack) is too high. Most commonly occurs when a pilot doesn't maintain sufficient airspeed in a climb or turn. Student pilots are trained in stall prevention, recognition, and recovery.
Results when a wing exceeds its angle of attack (angle between airfoil and relative flow of wind), the airflow is disrupted, and the wing no longer produces lift, with sudden drop and possible loss of control.
A condition in which an improper angle of attack and a lack of airspeed combine to disrupt the airflow around an airfoil enough to result in the loss of lift which forces the aircraft to drop.
The point at which the airflow breaks away from an aerofoil and lift is lost due to the change in the angle of the surface to the airflow. Can also happen to compressor blades of a gas turbine engine, causing loss of thrust.
a kite stalls when the air flow past it becomes detached from the kite surface and becomes turbulent. A stalled kite loses lift and falls.
As the wing angle of attack increases, the wing generates more lift until a maximum is reached. After this point, the wing is said to stall because it rapidly loses lift.
a malfunction in the flight of an aircraft in which there is a sudden loss of lift that results in a downward plunge; "the plane went into a stall and I couldn't control it"
a condition in aerodynamics and aviation where the angle between the wing's chord line and the relative wind, defined as the angle of attack, exceeds the critical angle of attack
a loss of lift and increase in drag that occurs when an aircraft is flown at an angle of attack greater than the angle for maximum lift
a (usually undesired) condition in aerodynamics and aviation
The complete loss of lift resulting from too steep an angle of attack.
loss of lift created by excessive angle of attack.
This occurs when there is a lack of motor power required for the current maneuver and the amount of lift needed to keep the model airborne is lost.
The point at which wings fail to generate enough lift to keep the plane stable. This is kinda my definition, not necessarily the official one. When a wing is angled against the wind enough, it doesn't hold the plane in the air very well -- it is the angle that causes this, not the speed of the plane (remember road trips as a kid when you held your hand out the window and angled it like a wing? When your hand went near vertical, it didn't force your hand near to the top of the window anymore, your arm fell to the bottom -- it stalled.) Since these angles can accidently be exceeded during takeoffs and landings, different types of stalls are practiced to the point of reflex at decent altitides so that you can learn without damaging the airport's runway.
Loss of lift resulting from exceeding the critical angle of attack.
Aeroplanes stall in a completely different way to cars: the engine is irrelevant. A plane stalls when the wings meet the air at too high an angle. The air cannot follow the curved top surface and instead breaks away in eddies and vortices. As a result lift ceases to be sufficient to support the plane. Due to the physical properties of air, a stall can happen very suddenly. A loss of height is the inevitable result. To recover, the pilot just has to get the air flowing quickly over the wing again. This is easily done by diving for a short distance, which builds up speed. However if the aeroplane is within 100 feet of the ground there may not be enough room to recover. Sufficient airspeed must always be maintained to avoid a stall. Early pilots were very vulnerable to the stall because (a) they did not understand it, (b) they flew slowly and (c) they often stayed low as their aeroplanes had poor climbing ability.
What happens when the angle of attack is too great to generate lift regardless of airspeed. (Every airfoil has an angle of attack at which it generates maximum lift -- the airfoil will stall beyond this angle).
A condition of flight where a lifting surface, such as a wing, stops producing a useful amount of lift and the aircraft starts to fall. Stalls are always due to attempting to operate the flying surface (usually the wing) at too high an angle of attack. This, in turn, is always caused by overuse of the elevator control.
As the name indicates, it's stopping the kite on the spot in the window. Air is said to stall when it becomes detached from the surface it is flowing along. Usually air travels smoothly along both sides of the sail, but if the sail is not properly trimmed, the air can leave one of the sides of the sail and begin to stall.
A condition of an airplane or an airfoil in which lift decreases and drag increases due to the separation of airflow.
A breakdown of the airflow over a wing, which suddenly reduces lift. When an airplane stalls it will usually drop suddenly. Pilots know how to recover from a stall and smooth out the airflow over the wings to produce more lift again.
The point at which lift is no longer generated by an aerofoil due to an extreme angle of attack coupled with low speed which in turn causes the airflow over the top of the aerofoil surface to degenerate into turbulence with consequent loss of lift.
the point at which the wing experiences a loss of lift; the aircraft will tend to drop abruptly.
The sudden loss of lift due to the disruption of airflow over the wings.
"Loss of lift" condition that occurs when the angle of attack is too steep for the airfoil to provide any lift. During a stall, the normally streamlined flow of air over the blade is disrupted.
When the angle of attack of a wing becomes too high to sustain lift, the wing is said to be stalled.
The reduction of speed to the point where the wing stops producing lift.
1) To stop moving. 2) Air is said to stall when it becomes detached from the surface it is flowing along. Usually air travels smoothly along both sides of a sail, but if the sail is not properly trimmed, the air can leave one of the sides of the sail and begin to stall. Stalled sails are not operating efficiently.
