Spin (aerodynamics) - Wikipedia
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]

Spins. Introduction: Practicing spins build awareness regarding the recognition of, entry into, and recovery from spins. An aggravated stall resulting in auto-rotation about the spin axis wherein the aircraft follows a corkscrew path due to one wing being more stalled than another.

2014年9月5日 · A spin is an aggravated stall with autorotation—one or both wings are stalled and the airplane rotates about a vertical axis. The outside, upward-moving wing has a lower angle of attack and, therefore, less drag.
The aerodynamic contributions are from the wing normal force which, for a stalled wing, acts at the wing semi-chord and from the tailplane normal force. The equations of motion for a steady spin show that the inertia moment is proportional to the square of spin-rate and reaches a maximum at 45 degrees angle-of-attack.

2024年1月13日 · The first step in spin recovery is reducing your throttle to idle. But why would you take power out when you're already stalled? In a normal stall, you add power to recover, but it a spin, adding power makes recovering more difficult. …

2017年3月13日 · A spin is a condition of stalled flight in which the airplane follows a spiral descent path. As well as the airplane being in a stalled condition, and yawing, one wing is producing more lift than the other, which results in a roll.
Aerodynamics: Spins - Learn To Fly
2015年6月8日 · A spin may be defined as an aggravated stall that results in what is termed “autorotation” wherein the airplane follows a downward corkscrew path. As the airplane rotates around a vertical axis, the rising wing is less stalled than the descending wing creating a rolling, yawing, and pitching motion.
Spin - SKYbrary Aviation Safety
A spin is a yaw aggravated stall which results in rotation about the spin axis. The aircraft follows a steep, "corkscrew" like, downward path. Spins can be entered, either intentionally or unintentionally, from any flight attitude and at practically any airspeed.

The bottom line is to resist the natural instinct to use out spin aileron and consciously check the stick is neutral during recovery. The engine and propeller also have a big effect on the characteristics of a spin.
