Allowing the experiment hardware to free fall a distance of feet m creates the microgravity environment at the Zero-G facility.
The free fall is conducted inside of a foot m long steel vacuum chamber. The chamber is 20 ft 6. A 5 stage vacuum pumping process is used to reduce the pressure in the chamber to a pressure of 0. Evacuating the chamber to this pressure reduces the aerodynamic drag on the freely falling experiment vehicle to less than 0.
To prepare for a drop, an overhead crane is used to position the experiment vehicle and release mechanism at the top of the vacuum chamber. Once in position, the drop vehicle is connected to the facility control room via an umbilical cable. This cable allows the experiment to be monitored and controlled from the control room until the release sequence is initialized.
It takes approximately one hour to evacuate the vacuum chamber. But in an indoor skydiving facility like iFly, you can float around and perform similar rolls and turns.
