Latest Patents

One of his latest inventions is the Rocket Motor Exhaust Scrubber. This device is designed as a wet scrubber with a series of chambers that capture and cool exhaust gases generated during static test firings of rocket motors. The exhaust gas enters an inlet to the first chamber, where it is cooled and slowed by a spray solution. Hydrochloric acid (HCL) gas is condensed and absorbed by the spray solution, precipitating to a liquid slurry at the bottom of the device. The remaining exhaust products then enter a demister chamber, where nozzles continue to spray the gases as they pass upward through a mesh-style demister at the top of the vessel. This demister filters liquid and solid waste particles from the gas stream, allowing clean, dry gases to be accelerated through a centrifugal fan into the atmosphere. Additionally, a deflector is positioned within the inlet to the first chamber to contain parts in the event of a motor malfunction.

Another significant invention by Armstrong is the Vented Rocket Motor Spacer. This invention serves as a direct replacement for a charge support spacer currently used in rocket motors. The vented spacer cools combustion gases through contact and expansion before equalizing pressure by transferring these gases from the inside of the propellant grain to the outside. The spacer cools the gases from combustion of the propellant by contact with and ablation of the spacer material, ensuring that the gases present no hazard to the rocket motor casing or the outside of the propellant grain.
