Research output: Contribution to conferencePaperpeer-review


In a companion paper1 we discuss the application of hypersonic computational fluid dynamics techniques to estimate radiation for vehicles with trajectories in the flight regime of 40 to 60 km altitude and at speeds of about 3.5 km/sec, and small nose radii. An experiment will be flown shortly to provide the first data to validate these calculations. In this paper, we show how the same computational tools have been used to help in the planning of instruments, primarily for the measurement of optical radiation in the ultraviolet. Theoretical predictions are shown for a sphere-cone vehicle with nose radius of 4 inches, at a speed of 3.6 km/sec between the altitudes of 40 to 60 kms and are also related to the specific radiometric and spectroscopic measurements planned.
