Active noise cancellation and related technologies are changing the interior experience for EVs and AVs. Experts from Silentium explain.

SAE International has published a new recommended practice for assessing the amount of nonvolatile particulate matter (nvPM) that exits aircraft engine exhaust nozzles – ARP6481: Procedure for the Calculation of Non-Volatile Particulate Matter Sampling and Measurement System Losses and System Loss Correction Factors

Medium-duty demonstrator intended for the North American market will feature a Cummins PowerDrive6000 drive unit mated to an Isuzu’s F-Series chassis.

Diesel engines continue to evolve to stay relevant while the industry intensifies its pursuit of zero emissions

Range, charging infrastructure, battery costs, etc. come to mind when discussing electric vehicles, but often overlooked are the vehicle’s noise and vibration characteristics.

Hydrogen fuels Wankel range extenders

Honda’s aerodynamic and NVH development gets a breath of fresh air from its first full-scale wind tunnel in North America.

Looking beyond EVs at other systems that can garner net-zero capabilities.

The aerospace industry is facing immense challenges due to increased design complexity and higher levels of integration, particularly in the electrification of aircraft. These challenges can easily impact program cost and product time to market. System electrification and electromagnetic compatibility (EMC) have become critical issues today. In the context of 3D electromagnetics, EMC electromagnetic compatibility ensures the original equipment manufacturer (OEM) that radiated emissions from various electronic devices, such as avionics or the entire aircraft for that matter, do not interfere with other electronic products onboard the aircraft.

While GAC member companies have led the industry in introducing alternative propulsion technologies to reduce greenhouse gas emissions and the GAC supports “de-carbonizing” transportation, the organization says that there has been no modelling done to gauge the impact on the Canadian automotive sector.

“We originally thought solar cells would be standard on the airplane’s wings,” says George E. Bye, founder and CEO of Bye Aerospace Bye. “However, with eFlyer’s primary markets being flight training and air taxi services, it makes more sense to make the price of the airplane as reasonable as possible.”

Hundreds of aerospace executives, engineers, scientists, and academics are gathering in London this week for Aerospace Systems and Technology Conference (ASTC) 2018 from SAE International in Warrendale, Pennsylvania. Discussions during the three-day industry event center on the theme of innovating air mobility. Aerospace thought leaders are at ASTC discussing current challenges, the latest enabling technologies, and future opportunities, including those related to urban air mobility (UAM) and supersonic aircraft.

LiquidPiston Inc. has developed a new engine that can run on multiple fuels, including diesel, jet fuel, and gasoline. This platform uses an optimized thermodynamic cycle and a new rotary engine architecture and could increases flight endurance over conventional UAV engines by greater than 50%.

NASA officials and engineers are prepping to fly the agency’s F/A-18 research aircraft over Galveston, Texas, using a “quiet thump” technique designed to reduce loud sonic booms typically associated with supersonic flight. This week’s test flight sets off a series of quiet supersonic research flights off the coast of Texas to test ways to measure supersonic aircraft sound levels and the community’s response to the supersonic acoustic experience.

The Terma 3D-audio system will enhance pilot situational awareness by supplementing the A-10C cockpit control panel visual warning system with audible directional signals from within the pilot’s helmet. The natural or spatially separately audio signals will be similar to what a human would hear when not wearing a conventional headset.

Officials and engineers at Boeing in Seattle are offering a glimpse into their vision for hypersonic air travel. They have released, for the first time, images of one of the company’s hypersonic air vehicle concepts for potential military and commercial passenger transport.

After taking off on July 11 in Arizona, the Zephyr S unmanned aircraft from Airbus Defence and Space logged a maiden flight of over 25 days – the longest-duration flight ever made without refueling.

Established on July 1, the ECLAIR consortium will focus on reducing greenhouse gas emissions and other negative environmental impacts of the aerospace industry by developing innovative electric technologies.

In April, NASA took another major step toward reintroducing supersonic flight with an award to Lockheed Martin Aeronautics Company to design, build, and test a supersonic aircraft to reduce sonic boom.
