However, they also pose unique challenges for both design and technology. The term “hypersonic” refers to any speed faster than five times the speed of sound, or above Mach 5. Modern hypersonic missile systems require extensive communications interconnects within a highly confined space. This space requirement creates a demand for solutions combining small form factor with reduced weight and rugged construction to withstand high vibration and impact conditions from deployment to target. Currently there are two types of hypersonic weapons. Hypersonic glide vehicles (HGVs), also known as boost-glide vehicles, typically launch from ballistic missiles and are released at a specific altitude, speed, and with the flight path tailored to a target without being powered. Hypersonic cruise missiles (HCMs) are powered all the way to their targets, flying at lower altitudes than Magazine Article more_vertlockExplaining MOSA from the Team that Led the Army Aviation Mission Computing Environment Task Order24AERP05_0105/01/2024In 2023, Parry Labs was awarded two tasks under the Aviation and Missile Technology Consortium's (AMTC) Other Transactions Agreement to lead a multi-vendor team to collaboratively define the Army's Modular Open Systems Approach (MOSA) requirements for computing and software operating environments for all future Army Aviation procurements. This relatively new approach for the Army and industry drove collaboration and allowed U.S. Government (USG) to make key modularity and openness decisions relative to Aviation Mission Computing Environment (AMCE). This unique opportunity provided a platform for industry to openly inform requirements at a much more granular level than previously possible, providing assurances that such detailed requirements wouldn't be an overreach or constrain innovation and disrupt industry business models. Solicited to the entire AMTC, which represents the vast majority of the aviation industrial base, the AMTC and USG team selected the most qualified vendors to Magazine Article more_vertlockAerospace Production: Overcoming Challenges in Composite Machining24AERP05_0305/01/2024Composite materials play an important role in aerospace manufacturing. The light weight, durability and ability to create complex shapes from molds make these materials ideal for frames and structural components that enable lighter, more fuel-efficient aircraft. While composite structures can weigh up to 20 percent less than their metal counterparts, these materials can often be more difficult to machine. The extremely abrasive nature of carbon fiber reinforced polymers (CFRPs) will wear down standard cutting tools more quickly than almost any other material. A standard carbide cutting tool may only hold up to cutting a few feet of CFRPs before its dimensional stability fails, while in traditional metal machining that same tool might last 20 to 50 times that before wearing out Magazine Article more_vertlockPortable Laser-Guided Robotic Metrology (PLGRMTBMG-5063905/01/2024Testing aircraft antennas is challenging since optimal tests are made after antenna installation. Aircraft are often taken to anechoic antenna test facilities which create long lead times, transportation hassle, and very high costs. Portable alternatives exist but often have compromised testing fidelity. Innovators at the NASA Glenn Research Center have developed the PLGRM system, which allows an installed antenna to be characterized in an aircraft hangar. All PLGRM components can be packed onto pallets, shipped, and easily operated Magazine Article more_vertlockFive Missile-Tracking Satellites LaunchedTBMG-5061105/01/2024L3Harris Technologies Melbourne, FL 585-465-3592 Magazine Article more_vertlockA New Optical Metamaterial Makes True One-Way Glass PossibleTBMG-5061905/01/2024A new approach has allowed researchers at Aalto University to design a kind of metamaterial that has so far been beyond the reach of existing technologies.

I used to attend as a reporter for other outlets, but I haven't been back to WCX since before the pandemic. It was different to walk the halls as editor of this magazine. What happens at WCX - and at dozens of mobility and transportation conferences around the world - is fascinating. I would bet big money that our readers agree. Still, sometimes it's difficult to translate the deeply technical work that makes up our days into something that piques the interest of those who don't spend inordinate amounts of time thinking about the “future of mobilityBlanco, Sebastian Magazine Article more_vertlockWhat's the Best DC Motor for Your Commercial Aerospace Application24AERP05_0205/01/2024In commercial aerospace, the application areas for motors are wide and varied, each with their own unique requirements. From electric vehicle take-off and landing (eVTOL) air taxis to business jets to long-haul commercial transport aircraft, DC motors must endure various environmental conditions like extreme temperatures, shock and vibration, atmospheric pressures and signal interference, to name just a few. These applications may also demand motors that provide a fast response, high power or torque density. In addition to these requirements, the aerospace industry perpetually calls for lightweight materials and smaller installation spaces. Taken together, it can be very difficult to specify and buy a reliable motor for mission-critical equipment. This article will present common commercial aerospace applications that pose performance and environmental challenges for DC motors along with a summary of the stringent aerospace industry standards that the motors must satisfy.
