In the ‘90s, NASA Lewis (today, NASA Glenn) used a DC-9 plane to help scientists study the behavior of fluids, combustion, and materials in a microgravity environment.
NASA Lewis Research Center’s DC-9 commences one of its microgravity-producing parabolas in the fall of 1994. It was the center’s largest aircraft since the B-29 Superfortress in the 1940s.A bell rings and a strobe light flashes as a pilot pulls the nose of the DC-9 aircraft up sharply. The blood quickly drains from researchers’ heads as they are pulled to the cabin floor by a force twice that of normal gravity.
Researchers conduct experiments in simulated weightlessness during a flight aboard the DC-9. The aircraft sometimes flew up to 40 parabolas in a single mission.In the 1960s, NASA Lewis used a North American AJ-2 to fly parabolas to study the behavior of liquid propellants in low-gravity conditions. The center subsequently expanded its microgravity research to include combustion and materials testing.
In the fall of 1993, 50 potential users of the aircraft visited the center to discuss the modifications that would be necessary to perform their research. In October 1994, the DC-9 arrived at Lewis in its normal passenger configuration. Over the next three months, Lewis technicians removed nearly all the seats; bolstered the floor and ceiling; and installed new power, communications, and guidance systems. A 6.
