The Air Force Research Laboratory's rocket propulsion division at Edwards AFB, Calif., is using a new piece of equipment, a Split-Hopkinson Pressure Bar system--known as a Kolsky bar--to aid eventually in the design of more resilient satellites and rocket motors. The Kolsky bar measures high strain rates and helps analyze materials under such stress, AFRL said. “This system will give AFRL a new and unprecedented capability to test and gather data from any solid propellant we can manufacture,” Timothy Miller,…
