Book excerpt: An analytical investigation has been made to determine the dynamic longitudinal and lateral stability and response of the HL-10 entry vehicle with particular reference to low-speed, high-angle-of-attack conditions. The calculations were made for light and heavy wing loadings for both sea level altitude flight. The results indicate that the HL-10 vehicle was dynamically longitudinally and laterally stable for the conditions investigated but that artificial damping in pitch and roll was required for some conditions in order to achieve a satisfactory degree of stability based on military handling qualities specifications for piloted airplanes.
