Computations for support design of measurements of radiation from low velocity shocked air
Abstract
The Innovative Science and Technology Office is planning a sounding rocket experiment which will measure the optical radiation produced at speeds relevant to exit trajectories. Here, the use of hypersonic computational fluid dynamics techniques to help in the planning of instruments, primarily for the measurement of optical radiation in the ultraviolet, is demonstrated. Theoretical predictions are shown for a sphere-cone vehicle with nose radius of 4 inches moving at a speed of 3.6 km/s between the altitudes of 40 and 60 km. The results are discussed in relation to the specific radiometric and spectroscopic measurements planned.
