A study of spin effects on tennis ball aerodynamics

Due to complex surface structure, the aerodynamic behaviour of a tennis ball is significantly different compared to other sports balls. This difference is more obvious when spin is involved. Although several studies have been conducted on drag and lift in steady state condition (no spin involved) by the authors and others, little or no studies have ...

Automated spin recovery under aerodynamic and load factor constraints

Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering
This paper addresses the problem of aircraft spin recovery with aerodynamic and load factor constraints. The spin recovery problem is divided into two phases. The first phase of the spin recovery problem is to stop the rotation and break the stall, and the second phase is to pull up to recover from the dive.
