Missile Aerodynamics Prediction: MISL3
Fast-running, engineering-level missile aerodynamics predictions for analysis and design. MISL3 efficiently predicts longitudinal and lateral aerodynamic characteristics including damping derivatives and is essential for generating aerodynamic data bases for flight simulations.
Models axisymmetric bodies with up to three fin sections with fully deflectable fins. Bodies may have conical changes in body diameter: flares and boattails. Based on high resolution, high angle-of-attack, experimental data bases and advanced equivalent angle-of-attack concept. Detailed body and fin vortex modeling for induced nonlinear effects between fin sets.
As an option, MISL3 can be linked with the store separation program STRLNCH for detailed aerodynamic analysis of store carriage loads and trajectories.
MISL3 is available for Windows and Linux computers subject to license fees and a software license agreement. AMA recommends a two-day training course which includes interpretation of the output and "hands-on" code running. Delivery to foreign countries requires U.S. State Department export license.
