DARPA’s MDP program aims for fast materials development for military platforms in extreme environments

August 7, 2018 Manufacturing, Material Comments Off on DARPA’s MDP program aims for fast materials development for military platforms in extreme environments

Military platforms—such as ships, aircraft and ground vehicles—rely on advanced materials to make them lighter, stronger and more resistant to stress, heat and other harsh environmental conditions. Currently, the process for developing new materials to field in platforms frequently takes more than a decade. This lengthy process often means that …

3D printing of Nanofibers has enabled power dense batteries, military wearables, chemical and biological defence

April 28, 2018 Manufacturing, Nanotech Comments Off on 3D printing of Nanofibers has enabled power dense batteries, military wearables, chemical and biological defence

A nanofiber is a fiber with a diameter of 100 nanometers or less. The nanofibers due to some special properties are being investigated for a myriad of potential applications in the fields of medicine, electronics and other material sciences. Such fibers have a high ratio of surface area to volume. …

September 29, 2017 Industry, Manufacturing, Military Comments Off on US DOD Technology Readiness Assessment (TRA) based risk assessment methodology stress on System Prototype Demonstrations in Major Defense Acquisition Programs

Federal agencies spend billions of dollars each year to develop, acquire, and build major systems, facilities, and equipment, including fighter aircraft, nuclear waste treatment facilities, electronic baggage screening equipment, and telescopes for exploring the universe. Managing these complex acquisitions has been a long-standing challenge for federal agencies.Many of the government’s most costly and complex acquisition …

DARPA robotic landing gear enables Unmanned Robotic Helicopter, to land on the Rough

November 7, 2015 Manufacturing, Unmanned Comments Off on DARPA robotic landing gear enables Unmanned Robotic Helicopter, to land on the Rough

Despite their airborne maneuverability, helicopters, with their skid-or-wheel landing gear, still need a level surface to set down which are scarce in combat and rescue missions. Landing on an uneven surface could them to tip over or the rotor blades to come into contract with the ground resulting in disaster. …
