Abstract:

Wind-tunnel tests were made on a rigid model of a balloon decelerator Ballute positioned at various axial locations in the wake of a cone-cylinder flare model. Pressure data were obtained on the Ballute model, and pressure surveys were made in the wake of the conecylinder flare model. The tests were made at Mach numbers from 1.5 to 6 and at Reynolds numbers, based on the parent body length, from 1.42 to 2.35 x 10 to the 6th power. Pressure distribution data on the Ballute model and pitot pressure survey data in the wake are presented.
