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 ... WebAbstract: Missile Datcom, a stability and control prediction code tailored to conceptual and preliminary design applications, has been developed. The program uses a component build-up approach based on the equivalent angle-of-attack concept. Simple vortex models are employed to allow for rapid and economical analyses.
