Testing Composite Structures for Stronger Bridges

The J. Lohr Structures Laboratory at South Dakota State University helps companies develop new materials and products — self-consolidating concrete columns and pre-stress concrete bridge girders — that bridge a physical gap. Over the past decade, researchers have conducted structural testing on large- and full-scale test specimens for private companies and government entities.

With New Sensors, NASA's Morpheus Preps to Land on its Own

A test flight will challenge a set of sensors to map out a 65-yard square of boulder-sized hazards and pick out a safe place to land. Mounted to an uncrewed prototype lander called Morpheus that flies autonomously several hundred feet above the ground, the sensor system will have 10 seconds to do its work. The sensor system is a 400-pound set of computers and three instruments called ALHAT (Autonomous Landing and Hazard Avoidance Technology).

Michelle Munk, Principal Investigator, Langley Research Center, Hampton, VA

Michelle Munk is Entry, Descent and Landing Principal Investigator for the Space Technology Mission Directorate. Most recently, Munk was the subsystem lead and the Deputy Project Manager for the Mars Science Laboratory Entry, Descent, and Landing Instrumentation (MEDLI) flight payload. NASA Tech Briefs: What is MEDLI? Michelle Munk: MEDLI is an instrumentation system that was put on the heat shield of the Mars Science Laboratory. It measured the pressure and temperature of the front face of the vehicle as it flew through the Martian atmosphere to land Curiosity on the surface.

Expanding GNSS Testing with Multiple Synchronized Signal Recorders

In order to greatly expand recording bandwidth, you can deploy multiple tightly synchronized recorders in the field. Averna studied the example of two RP-5300 recorders (2x50 MHz channels each) that were synchronously inter-connected to form a virtual recorder with total bandwidth of 200 MHz.

Flexible Wing Flap Reduces Noise and Drag

Shape-changing flexible wing flaps FlexSys Ann Arbor, MI 734-975-9233 www.flxsys.com FlexSys designed and built two experimental flaps for Armstrong Flight Research Center’s Gulfstream G-III Aerodynamics Research Test Bed aircraft. Researchers will replace the airplane’s conventional 19-foot-long aluminum flaps with the advanced, shape-changing assemblies that form continuous, bendable surfaces. The new flexible flaps are being prepared for ground vibration testing in NASA Armstrong’s Flight Loads Laboratory, followed by fit checks and eventual installation.

Control Software Navigates Lunar CubeSats

GNAT Programming Studio and GNAT Pro Compiler Software AdaCore New York, NY 866-787-4232 www.adacore.com Vermont Technical College’s Lunar CubeSat, measuring only 10 × 10 × 10 cm and weighing 1.1 kg, was launched into a 500-km earth orbit. The small satellite will remain in orbit for about three years to test the systems that will be used for an eventual lunar mission. The CubeSat project is part of NASA’s ELaNa (Educational Launch of Nano-satellites) IV program. The CubeSat’s navigation and control software was developed in SPARK/Ada using AdaCore’s GNAT Programming Studio (GPS) IDE and GNAT Pro compiler; the SPARK toolset from Altran, headquartered in Neuilly-sur-Seine, France, proved the absence of runtime errors.
