Rare Material Could Shorten Air Travel Times

An average flight from Miami to Seattle takes about six hours and 40 minutes, but imagine being able to reduce that time to 50 minutes or less. A recent study by NASA and Binghamton University researchers focuses on boron nitride nanotubes (BNNTs).

Shaping Aviation: Metal with Memory

Through NASA’s Convergent Aeronautics Solutions (CAS) Project, a team of engineers working within its Spanwise Adaptive Wing (SAW) project is investigating the feasibility of bending or shaping portions of an aircraft’s wings in-flight, potentially increasing performance and efficiency by reducing weight and drag.

Testing Large–Scale Vehicle–Borne Improvised Explosive Devices

In July of 2016, a refrigerator truck packed with explosives detonated next to a crowded apartment block in Baghdad’s Karrada neighborhood. The blast killed 323 people and was one of the worst Vehicle–Borne Improvised Explosive Device (VBIED also known as car bombs) attacks ever recorded. On May 30, 2017, a VBIED in a tanker truck ripped through the embassy quarter of Kabul, killing more than 150 people. Several embassies, including those of Germany and France, sustained damage despite the presence of blast protection structures.

Army Scientists Discover Power in Urine

Scientists at the U.S. Army Research Laboratory observed an unexpected result when combining urine with a newly engineered nano-powder based on aluminum. It instantly releases hydrogen from the urine at a much higher rate than with ordinary water.

Putting Smart Weapons to The Test

In the old days, a slingshot, BB gun, rifle or cannon was only as smart as the marksman taking aim. Now, many weapons are guided to their targets with the precision of infrared sensors and lasers. The technology continues to advance, but testing technology has lagged behind, leaving new generations of weapons and their tactical advantages unavailable to today's troops.

Simulation Results Could Help Quiet Jet Noise

Argonne National Laboratory engineers are working to create high-fidelity computer simulations to determine how jet turbulence produces noise. Working on Argonne’s supercomputer Mira, the team is applying computational fluid dynamics to capture the physics of the turbulence that is making the noise.

Airline Industry Could Soar on Sugarcane Fuel

Plants Engineered to Replace Oil in Sugarcane and Sweet Sorghum (PETROSS), funded by the Advanced Research Projects Agency - Energy (ARPA-E), has developed sugarcane that produces oil, called lipidcane, that can be converted into biodiesel or jet fuel in place of sugar that is currently used for ethanol production. With 20% oil – the theoretical limit – all of the sugar in the plant would be replaced by oil.
