EQUILIBRIUM AIR RADIATION FROM THE STAGNATION REGION OF HIGH VELOCITY SPHERES

EQUILIBRIUM AIR RADIATION FROM THE STAGNATION REGION OF HIGH VELOCITY SPHERES

Experimental air radiation intensity measurements were taken in the stagnation region of high velocity models. The models used were copper-clad nylon spheres. Initial range conditions varied in velocity from 16,000 to 19,000 feet per second, and in pressure from 8 to 24 torr. Radiation measurements...

Zusammenfassung:Experimental air radiation intensity measurements were taken in the stagnation region of high velocity models. The models used were copper-clad nylon spheres. Initial range conditions varied in velocity from 16,000 to 19,000 feet per second, and in pressure from 8 to 24 torr. Radiation measurements were taken over narrow (20A) bands in the spectrum from 2750 to 5900 angstroms. The experimental values were in close agreement with theoretical predictions. (Author)
