Products of Tomorrow: December 2015

The technologies NASA develops don’t just blast off into space. They also improve our lives here on Earth. Life-saving search-and-rescue tools, implantable medical devices, advances in commercial aircraft safety, increased accuracy in weather forecasting, and the miniature cameras in our cellphones are just some of the examples of NASA-developed technology used in products today.

Multiphysics Software Models Mean Flow Augmented Acoustics in Rocket Systems

Combustion instability in solid rocket motors and liquid engines is a complication that continues to plague designers and engineers. Many rocket systems experience violent fluctuations in pressure, velocity, and temperature originating from the complex interactions between the combustion process and gas dynamics. During severe cases of combustion instability, fluctuation amplitudes can reach values equal to or greater than the average chamber pressure. Large amplitude oscillations lead to damaged injectors, loss of rocket performance, damaged payloads, and, in some cases, breach of case/loss of mission. Historic difficulties in modeling and predicting combustion instability haves reduced most instances of most rocket systems experiencing instability into a costly fix through testing or scrapping of the system entirely.

Supercritical Wing Design Cuts Billions in Fuel Costs

NASA-developed wing design is used worldwide by commercial airlines. Langley Research Center aeronautics engineer Richard T. Whitcomb was 34 when he did something no other single person could do. Whitcomb overcame the aviation challenge of the day — the so-called sound barrier. However, he was still working to improve flight efficiency at speeds approaching that barrier, now with a seemingly counterintuitive wing design, almost the inverse of what were then conventional wings. He called it the “supercritical” airfoil.

Editor's Choice: December 2015

A Fluid Preservation System (FPS) was developed to address NASA’s need for a way to preserve body fluids collected from astronauts during flight. Sample processing is done within the system container, and the samples are hermetically sealed in a small, convenient package. Blood sample collection has significant commercial demand in areas such as cancer research, and for certain assays and bio-indicators. This application also extends to veterinary analysis and widespread monitoring of livestock, as well as use by first responders during natural disasters. Find out more HERE.
