Hydrogen fuels Wankel range extenders

The challenges of climate change and energy security require a continuous effort toward reduction of global environmental pollution and fossil oil consumption. To meet greenhouse gas (GHG) emission targets and to decrease oil dependency, overall energy consumption of vehicles must be substantially reduced.

A week prior to officially revealing its new N67 200 kVA Stage V solution installed on a genset frame concept at the Middle East Electricity show, FPT Industrial gave a sneak peek of the generator—in virtual form—to select international media at Pregnana Milanese, where about 90% of the company’s engines for power generation are produced.

On Sept. 12, NASA will conduct the first test flight of its latest heatshield, the Adaptable Deployable Entry Placement Technology (ADEPT) mechanically deployable semi-rigid aeroshell entry system.

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

OEMs and global suppliers are still betting big on hydrogen propulsion as a solution for decarbonizing the heavy-duty trucking industry.

As global emissions regulations tighten, the automotive and marine sectors lean into alternative-fuel development.

Alternative fuels and propulsion poised for growth in US fleets

United Airlines officials in Chicago have strengthened their commitment to ensuring United is an environmentally conscious carrier by expanding its contract with Boston-based World Energy and agreeing to purchase up to 10 million gallons of commercial-scale, sustainable aviation biofuel over the next two years. United currently uses the biofuel to help sustainably power every flight departing out of its Los Angeles Airport (LAX) hub and achieve more than a 60 percent reduction in greenhouse gas emissions on a lifecycle basis, officials say.

Continental Aerospace Technologies is partnering with Diamond Aircraft Industries GmbH of Austria to provide a new powerplant for the DA50 general aviation aircraft. Continental also recently expanded its portfolio with a “cash and in-kind contribution” investment in Ampaire Inc., an electric aircraft and propulsion company.

Standards development teams at SAE International in Warrendale, Pa., have issued 11 new technical documents and revised or reaffirmed another 54 technical reports focused on mobility engineering across the aerospace, automotive, and commercial transportation communities. The new documents, issued throughout June 2018, cover a variety of technical subject areas, including: diagnostic link connector security, mitigation strategies against illumination effects, data dictionary for quantities used in cyber physical exams, requirements for production of metal powder feedstock for use in additive manufacturing of aerospace parts, and laser powder bed fusion process.

Orbex, a developer of small satellite (smallsat) launch vehicles based in Forres, Scotland, has unveiled its “Prime” launch vehicle. The rocket utilizes several novel technologies, including the world’s largest metal rocket engine produced as a single piece through additive manufacturing (AM).

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%.

The four-year Clean High-Efficiency Diesel Engine (CHEDE) program is using a variety of new technologies and research findings to progress to a super-efficient, low-emitting heavy-duty diesel engine system with 55% brake thermal efficiency.

The strategy identifies 2025 as a target year to collaborate with communities around the globe and create products focused on environmental performance, emissions and waste reduction, and lower levels of water and energy consumption at work sites.

By using three hydrogen fuel cells, the five-passenger Skai can carry up to 1,000 pounds and fly for up to four hours, or approximately 400 miles, in between 10-minute refueling periods.

Parker Aerospace and GKN Aerospace sign development agreement for integrated thermal management technologies in next-generation aircraft engines.

Ceramic matrix composite (CMC) use is up across the aerospace market, and among the fastest-growing trends in the global aviation industry. CMC material and component use in aircraft engines, specifically, is projected to double over the next five years, according to a new report from analysts at Stratview Research in Telibandha, India.
