STRLNCH - old page
STRLNCH is a comprehensive 6-DOF store separation simulation software package applicable to high angle-of-attack launch from maneuvering aircraft at subsonic and supersonic speeds. Released store/missile aerodynamics are modeled by either the MISL3 or MISDL software.
Range of Flow Parameters
- Subsonic through supersonic Mach numbers
- Parent aircraft angles of attack/sideslip up to 60 degrees
- Arbitrarily maneuvering aircraft
- Nonzero rotational rates
Quantities Computed
- Launched store 6-DOF trajectory characteristics: translational and rotational positions, velocities and accelerations
- Overall 6-DOF forces and moments time histories: CA, CY, CN, Cl, Cm, Cn
- Fin forces and moments: CAF, CNF, CHM, CBM
- Detailed carriage load distributions on store body and fins

STRLNCH runs fast on workstations and PCs. Reduces need for costly wind tunnel tests. Indispensable in preliminary safe store launch assessment and parent aircraft/store integration studies. |
STRLNCH writes output files that are compatible with
Tecplot ® which allows viewing of 3-D animation
and 2-D plots of the released store trajectory characteristics.
The STRLNCH trajectory results can be read into spreadsheet programs.
