Computer Model More Accurately Predicts Flight Delays

Researchers at Binghamton University have devised a new computer model that can more accurately predict delays faster than anything currently in use. The multilevel input layer artificial neural network handles categorical variables with a simple structure to help airlines easily see the relationships between input variables (such as weather) and outputs (flight delays).

Cockpit Display Shows Precise Locations of Sonic Booms

NASA pilots flying supersonic aircraft now have a display that tells them exactly where sonic booms are hitting the ground. The display provided NASA research pilots the ability to physically see their sonic footprint on a map as the boom occurred. 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.

Laser-Based Navigation Sensor Could be Standard for Planetary Landing Missions

A laser-guided navigation sensor that could help future rovers make safe, precise landings on Mars or destinations beyond was developed at NASA’s Langley Research Center. The Navigation Doppler Lidar (NDL) will act as a GPS for Mars spacecraft.

Researchers 3D-Print Operational Drone with Embedded Electronics

Researchers at Nanyang Technological University, Singapore, 3D-printed a ready-to-fly drone with embedded electronics using aerospace-grade material. The electronics were incorporated in the drone during the 3D printing process, which used Stratasys ULTEM™ 9085 high-strength, lightweight FDM material certified for use in commercial aircraft.

32-Bit MCUs

Mouser Electronics, Inc. (Mansfield, TX) is now stocking the MSP432 mixed-signal microcontrollers from Texas Instruments (TI). TI’s MSP432 microcontrollers are based on a powerful, 32-bit ARM® Cortex®‑M4F core with a floating point unit and memory protection management. The microcontroller includes two 16-bit timers, four 32-bit timers, and a 14-bit analog to digital converter (ADC) that converts at 1MSPS. The microcontroller also boasts four high-drive input and output (I/O) pins that can support up to 20mA. The microcontrollers support capacitive touch capability, as well as digital glitch filtering on some I/O pins.

New Grasses Neutralize Toxic Pollution From Bombs and Munitions

On military live fire training ranges, troops practice firing artillery shells, drop bombs on old tanks or derelict buildings and test the capacity of new weapons. But those explosives and munitions leave behind toxic compounds that have contaminated millions of acres of U.S. military bases — with an estimated cleanup bill ranging between $16 billion and $165 billion. However, University of Washington and University of York researchers recently described new transgenic grass species that can neutralize and eradicate RDX — a toxic compound that has been widely used in explosives since World War II.

Researchers Develop High-Performance, Clean Solid Rocket Propellant

A Purdue-related startup is developing a new rocket fuel formulation that could make rockets used in military and space applications travel further, carry greater payloads, and be safer for the environment. Brandon Terry, a Purdue alumnus and postdoctoral research associate in Purdue’s Department of Mechanical Engineering, and Chris Stoker, an Indiana University alumnus, co-founded the company Adranos Energetics to develop the technology to enhance rocket performance.

Army Explores 3-D Printing's Future Applications

A soldier heads back to camp, grabs a power bar and unloads his gear. The power bar, which was "printed" minutes earlier, contains all the nutrients his body currently needs, according to sensors that are embedded in his uniform. While this may sound like a scene from a sci-fi movie, engineers and scientists at the Army Research, Development and Engineering Command (RDECOM) are looking at ways to use additive manufacturing (aka 3-D printing) to make it a reality.

Additive Manufacturing: How 3D Printing Will Transform the A&D Support Chain

3D printing, or additive manufacturing (AM), is quickly becoming a 'must have' for aerospace and defense (A&D) manufacturers rather than just a luxury R&D project with the A&D sector now contributing 12 percent of 3D printing's $3.1 billion global revenue. A&D companies began experimenting with 3D printing as early as 1988, and industry leaders are now starting to recognize the unique capabilities of 3D printing, and searching for ways to exploit them. The U.S. Navy is currently working on 3D manufacturing at sea, which would revolutionize the military support chain, while in civil aviation, companies such as Boeing and Airbus have been using the process to manufacture components for over two years.
