2024年1月30日 · The Electro-Motive Drop Tower (EMDT) is a proposed upgrade to the existing Zero Gravity Research Facility (ZGF) – NASA GRC’s 5.2-second drop tower. The initiative aims to improve the ZGF; increasing test throughput, low gravity duration, and providing intermediate gravity levels, such as lunar and Martian gravity.

2022年11月21日 · The NASA Glenn 2.2 Second Drop Tower is one of two drop towers located at the NASA site in Brook Park, Ohio. The tower, which began life as a 100-foot high fuel distillation tower, dangles over a bluff at the Glenn Research Center.

2024年11月8日 · The Zero Gravity Research Facility is the largest microgravity research drop tower in the world and one of 2 drop towers located at the NASA Glenn Research Center in Cleveland, Ohio. The facility is a National Historic Landmark and has been in operation since 1966. In over 50 years of operation more than 5100 drop tests have been conducted.

The facility also includes a smaller drop tower with a free fall time of 2.2 seconds and a much lower cost per drop. It is used for the Dropping in a Microgravity Environment (DIME) and What if No Gravity (WING) educational programs.

NASA has long benefitted from two drop-tower facilities built at what was then the NASA Lewis Research Center (now the Glenn Research Center (GRC)). The 2.2 second drop tower was built in 1959 by converting an old jet fuel distillation tower and the 5.2 second Zero-Gravity Research Facility (ZGRF) was completed in 1966.

The reduced gravity features comes from free fall, not the absolute reduction or elimination of Earth’s gravitational acceleration! Figure 8-7 is a plot of KC-135 parabola recorded in support of SAL experiment. Shows free-float of SAL test equipment …

• Recent improvements in drop tower systems/technology raise the potential for enhanced capability: – Increased duration – Increased throughput – Reduced cost – Partial Gravity – Variable Gravity • Comparable capabilities at extended durations but noiser g-levels exist on aircraft • Both platforms are adaptable to user needs.

Rapid prototyped experiments with a high rate drop tower completely(!) change the environment and productivity for such research. Data transfer and reduction become bottleneck, not experiment fabrication or data collection.

What makes this project so unique is the curvaceous exoskeleton, that encases the glass facades of the structure, made out of 5,000 lightweight Glassfibre Reinforced Concrete (GRC) panels. GRC was chosen for its structural versatility, aesthetic appeal, and its ability to withstand the often-extreme weather conditions of Miami – an area prone ...
