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.

‘NASA Invention of the Year’ Controls Noise and Vibration

Developed at NASA’s Langley Research Center, the Macro-Fiber Composite (MFC) is an innovative, low-cost piezoelectric device designed for controlling vibration, noise, and deflections in composite structural beams and panels. It was created for use on helicopter blades and airplane wings as well as for the shaping of aerospace structures at

Thermoelectric Devices Advance Thermal Management

When NASA programs need the ultimate reliability to power deep space probes, they repeatedly select thermoelectric (TE) devices as a system component. TE devices heat, cool, and generate electricity when a temperature differential is provided between the two module faces. Using radioactive isotope Plutonium 238 and TE devices to convert
