Vertical Acceleration Conditions in the NASA KC-135

Experiment packages are often flown on the NASA KC-135 to obtain information during conditions of microgravity. Accelerations different from 1-g and acceleration fluctuations can significantly affect experimental processes and instrumentation. For this reason, it may be very important to have an accurate knowledge of acceleration conditions prior to flight. This paper provides the acceleration characteristics during KC-135 flights and briefly discusses the implications of acceleration fields on two phase flow testing.
