ANALYSIS OF A PARACHUTE WITH A PULLED-DOWN VENT

Abstract

The analysis for flat circular canopies in steady descent is here extended to deal with canopies having a pulled-down vent. A general theory is developed, and a partial, approximate solution is found in closed form for certain conditions. The general theory is taken as the basis of a computer program. An example is worked out to demonstrate the use of the program in determining the optimum length of center line. The results are compared with tests and fairly good agreement is obtained. The most interesting outcome is the prediction that the maximum fabric stress is greatly reduced by pulling the vent down.
