摘要：
A resistively heated nozzle of silicon carbide (SiC) ceramic was developed for the production of high speed molecular beams for space environment simulation. The nozzle is able to withstand temperatures in excess of 1800 degrees C and pressures to 30 bars. In a seeded beam of 1% argon in 99% hydrogen, a speed of 3.9 km/s was achieved for the argon component at a nozzle temperature of 1150 degrees C and a pressure of 23 bars.
