Parachute Drag Model
- Created: Thursday, 01 July 2010
DTV-SIM is a computer program that implements a mathematical model of the flight dynamics of a missile-shaped drop test vehicle (DTV) equipped with a multistage parachute system that includes two simultaneously deployed drogue parachutes and three main parachutes deployed subsequently and simultaneously by use of pilot parachutes. DTV-SIM was written to support air-drop tests of the DTV/parachute system, which serves a simplified prototype of a proposed crew capsule/parachute landing system.
This program was written by Peter Cuthbert of Johnson Space Center. For further information, contact the Johnson Commercial Technology Office at (281) 483-3809. MSC-24361-1
