Researchers at NASA’s Armstrong Flight Research Center have dramatically improved upon existing ground collision avoidance technology for aircraft. NASA’s system leverages leading-edge fighter safety technology, adapting it to civil aviation use as an advanced warning system. It offers...

Spacecraft design is inherently difficult due to the complexity of the systems involved and the expense of testing hardware in a realistic environment. The number and cost of flight tests can be reduced by performing extensive simulation and analysis studies to understand vehicle...

The objective of this effort was to show that real-time aircraft control-surface hinge-moment information could be used to provide a robust and reliable prediction of vehicle performance and control authority degradation. For a given airfoil section with a control surface — be it a wing with an...

The Range Safety Algorithm software encapsulates the various constructs and algorithms required to accomplish Time Space Position Information (TSPI) data management from multiple tracking sources, autonomous mission mode detection and management, and flight-termination mission rule evaluation....

In this innovation, light weight, high temperature, compact aerospace structures with increased design options are made possible by using self-assembling, flexible, pre-ceramic composite materials. These materials are comprised of either ceramic or carbon fiber performs, which are...
