Sensors Increase Productivity in Harsh Environments

Originating Technology/NASA ContributionA team of scientists at Glenn Research Center, operating under the Aeronautics Research Mission Directorate’s Aviation Safety and Fundamental Aeronautics programs, developed a series of technologies for testing aircraft engine combustion chambers. The team, led by electronics engineer Dr. Robert Okojie, designed a packaging technique and chip fabrication

Novel Process Revolutionizes Welding Industry

Originating Technology/NASA ContributionDeformation resistance welding (DRW) is a revolutionary welding process—a new technique for joining metals—in an industry that has not changed significantly in decades. Developed by the Energy and Chassis Division of the Detroit-based Delphi Corporation (a spinoff company formed by General Motors in 1999), DRW can reduce the

Open-Lattice Composite Design Strengthens Structures

NASA has invested considerable time and energy working with academia and private industry to develop new composite structures that are capable of standing up to the extreme conditions of space. Over time, such technology has evolved from traditional monocoque designs, in which the skin of a metal structure absorbs the

Ultra-Sensitive Photoreceiver Boosts Data Transmission

In June 2006, NASA scientists used extensive data transmitted from the Chandra X-ray Observatory deep space telescope to prove that up to 25 percent of the light illuminating the universe comes from the “massive crush of matter succumbing to the extreme gravity of black holes.”

Micro Machining Enhances Precision Fabrication

In President Ronald Reagan’s 1984 State of the Union address, he announced plans for a U.S. space station, the equivalent of the Russian space station, Mir. This announcement set off a flurry of congressional funding debates, and it was not until 1988 that the President announced that a consensus had

Portable Hyperspectral Imaging Broadens Sensing Horizons

All objects reflect a certain amount of energy, even if it is just the electromagnetic energy created by the movement of electrically charged molecules. Measurements of these reflected energies, called spectra, can be used to create images of observed items and can thus serve to identify objects and substances. To

Hypersonic Composites Resist Extreme Heat and Stress

On October 14, 1947, Captain Charles “Chuck” Yeager made history when he became the first pilot in an officially documented flight to ever break the sound barrier. Flying a Bell XS-1 test jet over the Mohave Desert, Yeager hit approximately 700 miles per hour, when a loud boom thundered across

Computational Modeling Develops Ultra-Hard Steel

Glenn Research Center’s Mechanical Components Branch routinely conducts research on transmissions and gearing for advanced gas turbines, promoting their safety, weight reduction, and reliability. The Mechanical Components Branch is staffed by both NASA and U.S. Army Research Laboratory employees, and the research program is designed and executed to meet the

Thin, Light, Flexible Heaters Save Time and Energy

Ice accumulation is a serious safety hazard for aircraft. The presence of ice on airplane surfaces prevents the even flow of air, which increases drag and reduces lift. Ice on wings is especially dangerous during takeoff, when a sheet of ice the thickness of a compact disc can reduce lift

Novel Nanotube Manufacturing Streamlines Production

Nanotubes are sheets of graphite, one atom thick, rolled into seamless cylinders, with an exterior diameter in the range of nanometers. For a sense of perspective, if you were to split a human hair into 50,000 independent strands, a nanotube would be about the size of one of those strands.
