Notes on the Cause of Parachute Critical Velocity
Abstract
This report discusses how the critical velocity of parachutes depends upon the rate of outflow through the canopy surface and the rate of inflow through the canopy mouth. The analysis indicates that the mass flow rate ratio, M', is demonstrated to be the theoretical key to the critical velocity of parachutes. All other observed effects modify the onset of critical velocity. The effects of M' and altitude on inflation reference time, parachute stability, drag coefficient, and inflation rate are also discussed.
