Flight Test of High-Density Phenolic-Nylon on a Spacecraft Launched by the Pacemaker Vehicle System.

Abstract

High-density phenolic-nylon material was flight tested on a recoverable spacecraft launched by the Pacemaker vehicle system. The spacecraft was a hemispherically blunted cone with a cylindrical afterbody. The overall dimensions were a length ot 29.5 inches (74.9 cm) and a diameter ot 10 inches (25.4 cml. Ablation performance data on the phenolic-nylon were obtained by the use ot ablation sensors and thermocouples and by post-flight profile-change measurements. Profile-change measurements were also obtained for several panels of low-density materials attached to the spacecraft cylinder. A comparison ot measured heating rates with computed turbulent and laminar heating rates indicated that the boundary layer underwent transition.
