Analysis, Design, and Testing of Components of a Combined Ablation/ Erosion Nozzle

Abstract

An analytical and experimental study was made of the feasibility of developing a combined ablation and erosion test facility. A facility concept was developed in which particles are accelerated to high velocities in a light-gas expansion nozzle, followed by injection into an adjacent jet by inertial transfer across a mixing layer. A detail design was completed of a facility which utilizes a state-of-the-art arc-heated airflow and a helium expansion nozzle to produce 4,000- to 5,000-ft/sec particle velocities in a flow having an impact pressure of 80 atm. A cold-flow version of this facility was designed, fabricated, and operated to provide initial experience with the new configuration.
