Characterization of Bore Temperatures and Stresses in Small Caliber Gun Barrels

Currently in the small arms community, with the push for lighter, stronger barrels with improved life, a more complete understanding of the bore's thermal and structural behavior is required in order to not only improve future barrel design but to more thoroughly and accurately assess barrels in the current inventory.

Deep Installation Method for Three-Component Seismic Sensors

Successful sensor installation is important, as it directly affects how the sensor will perform. If conducted incorrectly, it could seriously degrade the data received and collective system performance. This is especially pertinent for three-component (3C) seismic sensors that have the additional parameters of orientation and leveling in addition to the need to be well-coupled to the surrounding media.

Making Flight Safer With the “Internet of Airplanes”

The Virtual Sky platform was developed to fuse and analyze flight sensor data correctly, reliably, and quickly. Virtual Sky would serve as a model extension of the FAA’s Next Generation Air Transportation System, a modernization of the National Airspace System that includes greater use of computer and satellite systems in air traffic elements like communication, navigation, weather, information management, and tracking.

New Flight Strategy Could Land Heavier Vehicles on Mars

The heaviest vehicle to successfully land on Mars is the Curiosity Rover at 1 metric ton. Sending more ambitious robotic missions to the surface of Mars, and eventually humans, will require landed payload masses in the 5- to 20-ton range. A recent study was conducted to determine how to land more mass.
