Spin — an aggravated stall and autorotation. In flight dynamics a spin is a special category of stall resulting in autorotation (uncommanded roll) about the aircraft's longitudinal axis and a shallow, rotating, downward path approximately centred on a vertical axis. [1]
When the mean angle of attack of the wings is beyond the stall a spin, which is an autorotation of a stalled wing, may develop. A spin follows departures in roll, yaw and pitch from balanced flight. For example, a roll is naturally damped with an unstalled wing, but with wings stalled the damping moment is replaced with a propelling moment. [9 ...
Spin — an aggravated stall and autorotation. For fixed-wing aircraft, autorotation is the tendency of an aircraft in or near a stall to roll spontaneously to the right or left, leading to a spin (a state of continuous autorotation). [1] [2]
A spin is more complex, involving intentionally stalling a single wing, causing the plane to descend spiraling around its yaw axis in a corkscrew motion. A hammerhead (also known as a stall turn ) is performed by pulling the aircraft up until it is pointing straight up (much like the beginning of a loop), but the pilot continues to fly straight ...
The main goal is to produce a more gradual and gentler stall onset, without any spin departure tendency, particularly where the original wing has a sharp/asymmetric stall behaviour [1] [3] with a passive, non-moving, low-cost device that would have a minimal impact on performance. A further benefit is to lowering stall speed, with lower ...
Stock indexes drifted to a mixed finish on Wall Street as some heavyweight technology and communications sector stocks offset gains elsewhere in the market. The S&P 500 slipped less than 0.1% ...
A stall, as aforementioned, happens when the flow of air over the top of the wing becomes separated due to a high angle of attack (this can be caused by low speed, but its direct cause is based on the direction of the airflow contacting the wing); the airfoil then loses its main source of lift and will not support the aircraft until normal ...
If passed, the bill would mean "spinning," under the definition above, would be a Class B misdemeanor; or a Class A misdemeanor if it endangered a person.
