PIFCALC, the Parachute Inflation Force Calculator Program

written by Dr. Jean Potvin and Gary Peek

The PCPRG has developed a new software diagnostic tool aimed at providing a user-friendly computer program for the computation of the maximum parachute drag force generated during inflation. Known as PIFCALC, or Parachute Inflation Force Calculator, this Windows-based platform uses a Graphical User Interface (GUI) to facilitate data entry. PIFCALC is much easier to use than OSCALC, the other GUI-based opening shock calculator produced by this Group, but applies to fewer parachute applications - namely that of manned parachutes opening along a purely vertical trajectory.
