[1] It presents substantiated techniques for use (1) early in the design or concept study phase, (2) to evaluate changes resulting from proposed engineering fixes, and (3) as a training on crosstraining aid.
For any given configuration and flight condition, a complete set of stability and control derivatives can be determined without resort to outside information.
A spectrum of methods is presented, ranging from very simple and easily applied techniques to quite accurate and thorough procedures.
Tables which compare calculated results with test data provide indications of method accuracy.
Fundamentally, the purpose of the DATCOM (Data Compendium), is to provide a systematic summary of methods for estimating basic stability and control derivatives.
