Software Accelerates Hypersonic Engine Development

Argonne National Laboratory and the Air Force Research Laboratory developed a new numerical modeling tool that allows for a better understanding of rotating detonation engines (RDEs). Unlike conventional gas turbine engines, RDEs leverage high-intensity, self-sustaining detonation to rapidly consume the fuel-air mixture, typically in a ring-shaped, cylindrical chamber.

Neural Lander Uses AI to Land Drones Smoothly

Landing multi-rotor drones smoothly is difficult. Complex turbulence is created by the airflow from each rotor bouncing off the ground as the ground grows closer during descent. Drones typically wobble and inch slowly toward a landing until power is finally cut and they drop the remaining distance to the ground.

Army Turns to Smart Technology to Protect Military Installations

Assistant Secretary of the Army for Installations, Energy and Environment Alex Beehler doesn't need proof of threats to military and government installations. He is reminded every day. His office sits next to the point of impact where American Airlines Flight 77 crashed into the western side of the Pentagon nearly 18 years ago during the 9/11 attacks. As the variety and complexity of threats continue to increase, security at U.S. military installations has taken increased importance in the years since 9/11.

AFRL Achieves “Shocking” Materials Technology Breakthrough

The Air Force Research Laboratory, along with research partners at Los Alamos National Laboratory, are working to change the shape of materials technology with a breakthrough development that could open up a new range of possibilities for the military and beyond. The collaborative team has developed a 3-D printed polymer-based foam structure that responds to the force of a shock wave to act as a one-way switch, a long sought-after goal in shock research.

NASA’s New UAV is 80% 3D-Printed

One of the keys to Urban Air Mobility (UAM) is exploring how different technologies and configurations of aircraft will perform in the urban environment. NASA’s newest modular unmanned aerial system, the Langley Aerodrome #8 (LA-8), is a testbed to investigate these technologies.

Hydraulic Propulsion an Alternative to Drone Batteries

Drones require heavy batteries or lots of electrical components, which leaves little room for the actual payload. A Purdue University team came up with a method to use fluid power technology for autonomous vertical takeoff and landing (VTOL) vehicles.

US and Japanese Scientists Conduct Joint Composites Study

Dr. Keisuke Umezawa of the Air Systems Research Center in the Japanese Ministry of Defense (JMoD) recently joined the Air Force Research Laboratory on an engineers and scientists exchange program (ESEP). The JMoD chose Umezawa for the ESEP based on his experience as a stress analysist of polymer matrix composite materials. Also, Umezawa has been heavily involved in the development of the next generation Japanese fighter aircraft, including the development of the test program for prototype PMC structures.
