The idea of stability derivatives is to approximate the general functional relationship between any force ormoment variable and the dynamic or control variables as a Taylor series expansion of the perturbation (i.e.small changes) about a trimmed flight condition. In non mathematical terms this simply means that weassume that we can approximate the functional relationship of the perturbation as a linear combinationof of the dynamic variables and control variables with the coeficients of these termed aerodynamicderivatives. Thus for example the perturbation z of the vertical force Z is expressed in terms of theperturbations of dynamic variables u, uw, w etc. and control variable terms such as due to the elevator
where the partial derivative coeficients are assumed constant at each particular flight condition.
An object, such as an aerofoil, moving through a fluid disturbs the surrounding flow field. The fluid velocity varies along the aerofoil surface creating a variation in pressure as
