Determination of the Elasticity of Parachute Materials under Dynamic Loading Conditions


In the design of parachute systems it is important to use material properties that have been acquired under representative strain rates expected in flight. Without such data the designer is potentially forced to incorporate unrealistic safety margins resulting in a heavier and costlier than required design. Laboratory test data has generally been limited to that which can be acquired at quasi-steady strain rates. This paper investigates a technique, which takes advantage in solid state electronics in the past ten years, to achieve an economical means of acquiring material properties under dynamic strain conditions. Data obtained with this technique is compared to standard test data for representative parachute materials.
