MACH 8 AERODYNAMIC AND AEROTHERMODYNAMIC CHARACTERISTICS OF THE NIMBUS B SPACECRAFT AND SNAP-19 NUCLEAR GENERATOR

Abstract

Static-stability and axial-force characteristics were obtained on a 10-percent scale model of the Nimbus B spacecraft and on a 30-percent scale model of the SNAP-19 nuclear generator at angles of attack from 0 to 180 deg and model roll angles from 0 to 225 deg on the Nimbus and from -60 to 270 deg on the SNAP-19 models. Heat-transfer distributions were obtained on three 30-percent scale models of the SNAP-19 generator with various fin lengths to simulate fin ablation and at angles of attack from 0 to 90 deg and model roll angles of 0 and 30 deg. The tests were conducted at Mach 8 at a free-stream Reynolds number of 0.4 million per foot. Selected results are presented to illustrate the types of data obtained.
