Question about spoilers and pitch stability
On Sun, 03 Feb 2013 19:43:06 -0800, Terence Wilson wrote:
Opening the spoilers reduces the coefficient of lift. After the first 'bounce', which results in an increase in the angle of attack, the reduced CL dampens the lift vector and amplitude of the PIO. It also pushes the Cd up, which always makes things less twitchy because increased drag tends to damp out pitch changes. -- martin@ | Martin Gregorie gregorie. | Essex, UK org |
