Abstract : This report documents the longitudinal and lateral-directional aerodynamic analysis of a single-engine business jet aircraft. A Euler level analysis was chosen for the evaluation because of the size of the problem (complete aircraft with inlet and nozzle flow simulated) and the relatively large number of runs desired. While Euler analyses ignore viscous effects, ft was determined that these effects would be small (except on drag estimates) for the cruise and low-speed flight conditions under consideration. Also, the primary emphasis was on providing incremental effects from a baseline condition, which is more accurate than absolute values. Variation of longitudinal and lateral-direction characteristics with Mach number, angle of attack and control deflections were determined. The maximum Mach number is up to the estimated wing drag divergence Mach number. Integrated force coefficient data and selected pressure coefficient data are presented. Comparisons with low-speed wind tunnel data are made where appropriate experimental data is available.
