Web5.5.5 DATCOM method for leading edge slats and flaps. Though leading edge flaps, that is, hinged nose sections on airfoils, have been the subject of much study they are not used on any commercial aircraft. The leading edge slat is the most common leading edge device in wide use. The leading edge slat is analogous to the slotted trailing edge ... WebDescription of the FDerivatives code. The model implemented in the new FDerivatives code is based on the methodology used in the DATCOM procedure (Williams et al., 1979a) for calculating the aerodynamic coefficients and their stability derivatives for an aircraft. The main advantage of this new code is the estimation of the lift, drag and ... iqor application
