IHS ESDU Computer program for prediction of aircraft lateral stability derivatives in sideslip at subsonic speeds. 00025

ESDU 00025 describes the construction of input files for the FORTRAN program ESDUpac A0025, which combines and extends the prediction methods of twenty five individual ESDU documents to evaluate the lateral stability derivatives in an aerodynamic-body axis system. The effect of under wing pylon-mounted jet engine nacelles or wing-mounted nacelles for propeller driven aircraft is included. The deflection of up to four flap panels on each half-wing is permitted. Worked examples illustrate the use of the program.
