Determining the Dose Response Profile of the Headward Fluid Shift During Varying Gravity Levels

"The aircraft will fly in parabolas that initially produce increased gravity (1.8-G, hypergravity), followed by \~20-50 second periods of partial gravity or weightlessness. Flights which produce partial gravity (0.25-, 0.50-, and 0.75-gravity) generally will consist of 31 parabolas (at least 10 parabolas at each gravity level), and flights that produce weightlessness generally will consist of 16 parabolas."
