MISDL: Detailed Missile Loads
Fast-running program MISDL employs elements of classical aerodynamic theory, including vortical theory
The software package predicts overall aerodynamic performance coefficients and detailed aerodynamic loading distributions on the body and lifting surfaces of flight vehicles, including: missiles, munitions, mortars, aircraft, UAVs, etc.
MISDL can model configurations with circular and noncircular bodies, including those with chines. The finned sections can have planar, triform, cruciform, and low profile fin layouts. Fin planform can be arbitrary. Effects of rotational rates (damping) and of nonuniform flow are included. The overall and detailed aerodynamics predicted by these programs are useful to aerodynamic, structural, and control system engineers.
As an option, MISDL can be linked with the store separation program STRLNCH for detailed aerodynamic analysis of store carriage loads and trajectories.
MISDL is available for Windows and Linux computers subject to license fees and a software license agreement. We recommend 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.
