Computation of Wing Deflection and Slope from Measured Strain
Researchers at NASA’s Armstrong Flight Research Center have developed a revolutionary new method to compute wing deflection and slope from measured strain of an aircraft during flight. The technology is based on a lightweight, robust fiber optic system that is small, easy to install, and fast. It offers the first-ever means of obtaining real-time strain measurements while an aircraft is in flight. Such measurements are particularly useful for real-time virtual displays of wing motion; aircraft structural integrity monitoring; and actively reducing drag, controlling flexible motion, and alleviating loads.

Low-Cost, Low-Power, Portable Mounting Platform for Auto-Tracking Antenna
Researchers at NASA’s Armstrong Flight Research Center have designed an innovative antenna-mounting platform that addresses an unmet need in the unmanned aerial vehicle (UAV) market by integrating multiple capabilities onto one low-cost platform. Capable of aiming four or more interchangeable antennas of any type, this unique continuously rotating platform is portable and can position and hold nearly 60 pounds of antennas and radios at its full rated speed, limited in number only by the size of the mounting bar installed on the platform. It is ideal for use with any moving system needing to transmit large quantities of data over one or more RF links. Possibilities include maintaining data links with UAVs and other aircraft used for academic and government research as well as communicating with marine ships in line of sight and in tracking satellites in non-geosynchronous (i.e. low-Earth) orbit. In fact, it could be used to track any line-of-sight object carrying multiple radio frequency (RF) sources which require directional antennas at one end of the link.

Improved Ground Collision Avoidance System
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 higher fidelity terrain mapping, enhanced vehicle performance modeling, multidirectional avoidance techniques, more efficient data-handling methods, and user-friendly warning systems. The algorithms have been incorporated into an app for tablet/handheld mobile devices that can be used by pilots in the cockpit, enabling significantly safer general aviation. This will enable pilots to have access to this lifesaving safety tool regardless of what type of aircraft they are flying. The system also can be incorporated into electronic flight bags (EFBs) and/or aircraft avionics systems.

Improved, Real-time, Interactive Sonic Boom Display
A series of flights, recently flown at NASA’s Armstrong Flight Research Center in Edwards, California, featured a display that allowed NASA research pilots the ability to physically see their sonic footprint on a map as the boom occurred. The series, which marked the second phase of the Cockpit Interactive Sonic Boom Display Avionics project, or CISBoomDA, continued from the project’s first phase, where only a flight test engineer could see the display.
With the ability to observe the location of their aircraft’s sonic booms, pilots can better keep the loud percussive sounds from disturbing communities on the ground.
NASA’s supersonic research projects are helping engineers develop the means to design and build a proposed Low Boom Flight Demonstrator experimental aircraft, or X-plane, as part of the agency’s New Aviation Horizons initiative. The X-plane would be designed to demonstrate what NASA believes could be a quieter thump in place of the louder sonic boom. This could, in the future, introduce the opportunity to permit supersonic flight over land.
The display will ultimately be used to help NASA proceed with supersonic research in a way that minimizes disturbance on the ground and provides practice with the future of supersonic technology for pilots such as NASA research pilot Nils Larson.
