Yeah, r is taken into account. But I guess the point of my input was to highlight that r (chassis rotational velocity) does not equal ay/V, or even an/V. Omega (the rotational velocity of the velocity tangent direction) does is equal to an/V, and to find r from omega you need to remove the body slip velocity. So yeah, you can take r into account, but you need to ensure you have the right value of r.Originally Posted by Claude Rouelle
Also, while small angle approximations might make sense if calculating the slip angles once or twice, I would hazard to suggest that if you are going to determine a Cn-Ay or Az-An diagram it may be worth the extra computational expense to make use of proper cosines et al.
