    Abstract

    Dynamic pitch response of a water landing space module (WLSM) during a postsplashdown situation was investigated. Analysis of test results using a one fifth scale model are reported. Tests were performed for various center of gravity (c.g.) locations with and without use of flotation/stabilization aids. These aids were in the form of attitude spheres attached to the model just below the water line. Data and information obtained from testing established trends for different model configurations. Pitch oscillation increases resulted as the c.g, was offset horizontally. Less significant pitch oscillation increases were observed with an increasing vertical c.g. offset. The application of attitude spheres reduced the pitch oscillations for all c.g. configurations investigated. Measuring the pitch motion of the WLSM in different configurations identifies design parameters useful in smoothing the ride for the sick or injured crewmember in the postsplashdown environment. The results obtained are suggested design considerations for a full-scale WLSM.
