Reusable Rapid Prototyped Blunt-Impact Simulator

Rapid prototyping (RP) is the term most commonly used to describe additive manufacturing technologies. An additive manufacturing technology is any manufacturing process that fabricates a part by adding one layer of material at a time, one on top of the other, to produce detailed 3-D geometries directly from 3-D computer-aided design (CAD) models.

Producing Manufacturing Aids with HP Multi Jet Fusion 3D Printing

In the era of mass production and lean manufacturing, companies are looking for ways to help boost productivity and reduce unit costs while maintaining quality and repeatability. The focus is on continuously improving production techniques, accelerating the various phases within the Product Lifecycle while keeping costs at a minimum. Manufacturing aids such as jigs, fixtures, quality control aids, dies and punches and dummy parts play a critical role here.

Ducted Fans for Aircraft Propulsion

One alternative aircraft propulsion technology being explored is an array of electrically powered ducted fans distributed across the wing span or integrated into the wing. Researchers are studying the cross-communication – or cross coupling – between the aircraft engine’s RPM and the airflow characteristics about the airplane wing.

Electronic Warfare Creates Battlefield on a Different Wavelength

Soldiers on the ground are now capable of rapidly reacting to electronic and cyber data rather than waiting on their higher echelons. Soldiers assigned to Headquarters and Headquarters Company, 1st Armored Brigade Combat Team, 1st Cavalry Division, currently deployed in Poland, are among the first brigades supporting Atlantic Resolve to train on a new system that enables a team to forward deploy and respond to enemy frequencies using new electronic warfare (EW) technology.

Sandia Delivers First DOE Sounding Rocket Program Since 1990s

A new rocket program could help cut research and development time for new weapons systems from as many as 15 years to less than five. Sandia National Laboratories developed the new program, called the High Operational Tempo Sounding Rocket Program (HOT SHOT), and integrated it for its first launch earlier this year under the National Nuclear Security Administration’s direction.

Army, ASU Collaboration Produces Alloy with Superhero-Like Strength

Researchers from the U.S. Army Research Laboratory and Arizona State University (ASU) have designed a super-strong alloy of copper and tantalum that can withstand extreme impact and temperature. It's likely the closest material on earth to vibranium, a rare, fictitious metallic substance found in Marvel's Wakanda and used in Captain America's shield.

DETECTING PLASTIC LANDMINES

Hidden PFM-1 anti-personnel landmines are unexploded ordnance (UXO) devices that pose a difficult challenge to conventional landmine detection methods like metal detecting because the mines are primarily composed of plastic and only weigh 75 g. As a remnant of the Soviet-Afghan War, there are an estimated 10 million such devices scattered throughout Afghanistan. These mines remain in isolated locations, frequently out of reach of de-mining nongovernmental organizations (NGOs) and act to thwart local economic and social development. The PFM-1s are infamously referred to as “toy mines,” as children often mistake the mines for toys and set off the 525 kg of cumulative pressure it takes to detonate them.

Optimizing Winglets for More Efficient Flight

Airplane winglets reduce drag, which can translate to higher speed or to allow a pilot to throttle back and save fuel. It also helps to reduce wingtip vortices that can be problematic for airplanes flying in their wake. Although winglets have been around since the mid-1970s, there is still a wide variety of shapes, sizes, and angles.
