Summary on Grant Application Form |
A two stage light gas gun has been commissioned and designed at UMIST; this is capable if launching a range of projectile up to 25gm at velocities of 1km/s. Various projectiles are transoprted along the gun barrel in a sabot which is shed or stripped in the sabot chamber.This project will evaluate and develop a specific type of projectile/sabot; a very small projectile is located at the front of the cabot, the latter being used as a cannister for a coil of fibre or yarn. The sabot will continues and extract the other end at speeds of up to 1km/s. This mechanism has been tested and functions well. Witness plated have been used to measure the progress and decelleration of the projectile, 30-50cm of Twaron yarn being the payload, giving a typical strain rate of 3000/s.Instrumentation to measure the fibre/yarn force-extension behaviour will be developed. Fibre loads will be measured by strain gauging in the sabot catcher and activated on contact; some preliminary designs have been tested and have performed well. Photography will be used for fibre extension.
