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.

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.

Blast Tube Tests Simulate Shock Waves Nuclear Weapons Could Face

You can learn a lot from a blast tube when you couple blast experiments with computer modeling. Sandia National Laboratories researchers are using a blast tube configurable to 120 feet to demonstrate how well nuclear weapons could survive the shock wave of a blast from an enemy weapon and to help validate the modeling.

Sandia recently completed a two-year series of blast tube tests for one nuclear weapon program and started tests for another. Each series requires instrumentation, explosives, high-speed cameras and computer modeling. Tests simulate part of the environment a weapon re-entering the Earth’s atmosphere would face if another nuclear weapon went off nearby, said test director Nathan Glenn.

Unique Chamber Gives Air Force Real-World Corrosion Test Capabilities

Aircraft corrosion is a multi-faceted issue that requires more than a simple, one-dimensional approach. To enable Air Force Research Laboratory (AFRL) personnel to arrive at a complete picture and find out how to best protect valuable military assets, a unique solution was required.

Enter the Accelerated Combined-Effects Simulation test apparatus (ACES). This test chamber, custom-designed under the direction of AFRL through a Small Business Innovative Research effort, allows AFRL researchers to recreate the broad range of simultaneous environmental conditions under which military assets operate, including UV radiation, temperature, humidity, and various gaseous environments. Dynamic fixtures allow for test specimens to be pulled and flexed to further simulate the structural stresses aircraft experience during flight conditions.

Digital Transformation for a CONNECTED ENTERPRISE

Manufacturers around the world are grappling with the challenge of continuous innovation in the face of increasing complexity. In aerospace and defense (A&D), complexity is nothing new, but digital transformation to become a more connected enterprise that allows programs to run independently while achieving enterprise-wide processes remains an elusive goal. Today, organizations around the world are rethinking their strategies and turning to more open and agile approaches to create a connected enterprise that can enable faster innovation.

Thermostatic Solutions for Temperature Control Applications

The wax-filled thermostatic element was invented in 1936 by Sergius Vernet (1899-1968). Its principal application was in automotive thermostats used in the engine cooling system. Wax thermostatic elements transform heat energy into mechanical energy using the thermal expansion of waxes when they melt. In addition to engine cooling systems, this wax motor principle also finds applications in heating system thermostatic radiator valves, plumbing, industrial, and agriculture. Today this technology is widely used across a broad spectrum of industries including aerospace & defense, most often for temperature control of various fluid systems.

New Products: October 2018 Aerospace & Defense Technology

Microstepping Motor Driver

US Digital (Vancouver, WA) announced the release of the MD3 Programmable Microstepping Motor Driver, capable of driving motors from NEMA size 14 to 42. The MD3 accepts 9-50 VDC power inputs and is rated for currents up to 7A continuous duty. In addition to digital input controls, the MD3 can be configured and controlled using the open MODBUS RTU protocol over a RS485 bus. A GUI application is supplied that allows many settings to be changed including the number of microsteps per full step, acceleration/deceleration rates, speed and current cutback. The design supports multiple MD3 units on the same RS485 bus and allows for programmable motion profiles. In addition, the MD3 has a brushed DC motor speed control mode.

Army to Purchase Additional Soldier Borne Sensor Systems

For soldiers in combat, situational awareness – knowing where the enemy is and where friendly forces are – is critical.

To help soldiers maintain situational awareness, the U.S. Army submitted a draft Request for Proposal for Soldier Borne Sensors, which will have two components – an unmanned aerial vehicle and a ground control station. With a camera in the air vehicle, soldiers will be able to see further and around obstacles that they previously wouldn't be able to see in near-real-time.
