Does Your Coating System Require Climate Control? What to Look For and What to Expect

There is one aspect of the paint and coatings finishing business virtually guaranteed to give the budget director heart failure: climate control. There's no way around it – climate control systems are expensive.

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.

Airbus, Georgia Tech Open Aircraft Design Center

Airbus and Georgia Tech opened the Airbus/Georgia Tech Center for Model-Based Systems Engineering (MBSE)-enabled Overall Aircraft Design (OAD). The center will contribute to the development and demonstration of a concurrent overall aircraft design process with a team of 30 Georgia Tech researchers, doctoral students, and Airbus experts.

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.

The researchers learned how that coupling between ducted fan systems and wing sections will modify the aerodynamic behavior and the overall lift, drag, and pitching moment characteristics.

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.

Electronic warfare, known as the battle in the electromagnetic spectrum, relies on data and signals to survey, fight and defend. Collecting enemy radio signals, sensing radar of an incoming threat, and utilizing radio waves to confuse or disable an enemy's electronic communication methods are all means in which electronic warfare specialist teams strive to train to perfection. Team members are learning to better operate and integrate EW capabilities, including the VROD, VMAX and Raven Claw. The VROD and VMAX are part of the backpack system that surveys the field from an electromagnetic perspective and delivers limited electronic assault capabilities such as signal interception and jamming. Raven Claw, a mobile computer system, offers on-the-ground planning and management without any network connection.

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.

The first HOT SHOT rocket launched from Sandia’s Kauai Test Facility in Hawaii in May, marking the first time the DOE has used rockets carrying scientific instruments, also known as sounding rockets, since the 1990s. Sandia is planning four launches next year.

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.

Its structure and deformation response make it a candidate for ballistic impact or protective applications for military vehicles or personal protection for soldiers, said Dr. Kristopher Darling, a materials scientist with ARL's Lightweight and Specialty Metals Branch. Darling said that even beyond the Army, "anywhere there's high strength and good electrical conductivity required, these alloys can be thought of as a model system whose structure can be passed on to other alternative material systems. Materials based on iron or aluminum, for instance, could be used for protection and lethality applications."

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.

Researchers developed an algorithm that generates a wing that has the minimum drag, and ultimately will be more efficient. The integrated optimization framework will assist the current state of low-speed wing design and may also result in an improvement over the current conventional wing designs.
