Effects of Relaxed Static Longitudinal Stability on a Single-Stage-to-Orbit Vehicle Design.

Abstract

The effects of relaxing longitudinal stability requirements on single-stage-to-orbit space vehicles were studied by comparing the mass and performance characteristics of two vehicles, one designed for positive levels of longitudinal stability and the other designed with relaxed stability requirements in a computer-aided design process. Both vehicles were required to meet the same mission characteristics. Wind-tunnel tests were conducted over a Mach number range from 0.3 to 4.63 to verify estimated aerodynamic characteristics.
