Study tests performance of electric solid propellant

Electric solid propellants are being explored for use in dual-mode rocket engines because they aren't susceptible to ignite from a spark or flame and can be turned on and off electrically.

High-speed experiments improve hypersonic flight predictions

When traveling at five times the speed of sound or faster, the tiniest bit of turbulence is more than a bump in the road, said the Sandia National Laboratories aerospace engineer who for the first time characterized the vibrational ...
