  • Rocket exhaust probe
    Patent number: 4662216
    Abstract: A rocket exhaust probe 10 for collecting particulates from a rocket exhaust plume. The probe comprises a tungsten nose tip 18, a tip holder 20, a probe body 22 and a tail section 24. Rocket exhaust gas enters the probe at the nost tip inlet 32 and passes into a mixing chamber 36 where the exhaust gas mixes with an inert cooling gas that cools and decelerates the exhaust gas. The mixture of exhaust gas and inert gas then passes into a diffusion chamber 50 where it further cools and decelerates before passing through a submicron particle collection filter 52.
