STORE SEPARATION ANALYSIS AND PREDICTION
STRLNCH (SToRe LauNCH) SOFTWARE

STRLNCH is a comprehensive 6-DOF store separation simulation software 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 deg.
  • 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 work-stations and PCs. Reduces need for costly wind tunnel tests. Indispensable in preliminary safe store launch assessment and parent aircraft/store integration studies.


      The MBGX software is a graphics display program for STRLNCH: 3-D animation and 2-D plots of trajectory characteristics for SunSPARC and SGI workstations.


    The STRLNCH trajectory results can be plotted with the MBGX graphics display program. MBGX is available for both SunSPARC and SGI workstations.
