Abstract

While performing maintenance and assembly tasks outside of space vehicles under weightless conditions, a worker may accidentally propel himself away from his vehicle. To determine the speed of such a single-impulse launch, subjects under weightless conditions in a zero-G KC-135 aircraft propelled themselves away from a surface with their legs. They attained maximum velocities of approximately 10 mph. Using various launch speeds and directions, theoretical trajectories have been projected for both coplanar and noncoplanar launches. These trajectories indicate that any launch having a velocity component parallel to the direction of orbital motion will result in a trajectory such that the worker will never return to his vehicle.
