Chine-Backed Flame Diverter for Rocket Systems
Systems of chine-backed flame diverter for rocket systems are described. The chine-backed flame diverters can use a lower water supply pressure relative to the rocket exhaust plume impingement pressure. The chine-backed flame diverter systems can reduce operation costs and increase rigidity of the test stand structures.
