After days of fretting over when and where an out-of-control Chinese rocket would land as it fell back to Earth, China announcedearly Sunday that the rocket had landed in the Indian Ocean near the Maldives.Although it was unclear whether the debris had caused any damage, NASA sharply scolded China for failing to be responsible with its space debris.

What are the main challenges to using electric propulsion in commercial aviation?

Graham Warwick, Aviation Week’s Executive Editor, Technology, and France Bureau Chief Thierry Dubois team up to answer:

Challenges to the use of electric propulsion in commercial aviation are many and range from the batteries and motors to the wiring and cooling. But from the beginnings in automotive technology, progress is taking place in tailoring electric drive trains to aerospace applications.

The biggest challenge is the low energy density of batteries. Jet fuel has an energy density of about 12,000 Wh/kg whereas commercially available lithium-ion batteries have an energy density at the cell level of about 250 Wh/kg. Energy density at the pack level, including the weight penalty for thermal-runaway containment and other safety features, is typically 20% lower.

Although that might seem an impossible gap to bridge, electric-propulsion pioneers believe that they can develop commercially viable small, short-range aircraft using available batteries. “Small” refers to aircraft with up to 19 seats, and “short-range” pertains to distances less than 250 mi.—enough range for many regional routes, the pioneers argue.

A quick and easy way to download and print any USGS 7.5 minute topographic quad
 

National Geographic is allowing everyone to easily download any USGS 7.5 minute topo map in the continental U.S. as a multi-page PDF that can be printed on letter size paper on any printer. These are the same topographic maps that were published by the U.S. Geological Survey for decades, with nice additional features from our much-loved, but discontinued TOPO! software product, including:

Page 1 is an index map showing each of the printable quarter-quad maps in their broader context
Pages 2-5 are the topo quarter-quads, sized and scaled to print on US-letter size paper
We've added hillshading to help visualize the topography
NOTE: Since the USGS stopped updating their printed topos decades ago, some of these maps do not accurately reflect the current landscape. For the most detailed and up-to-date maps of popular outdoor recreation areas, we recommend our Trails Illustrated maps.

This Bladeless Air Taxi Has a Wild Propulsion System

お馴染みAir Taxi VTOL航空機の記事です。

安全性を考慮し、今回のVTOLはBladeless (羽根なし)の新型機らしいですね!

実現する機体は、いつになるのでしょうか?

ともかく、英語の習慣化の題材です。

Jetoptera, a Seattle-based propulsion system, drone, and aerial mobility startup, is working on an innovative vertical takeoff and landing (VTOL) aircraft concept modeled on Dyson’s “bladeless fan” design. Could the design lead to quieter, more efficient VTOL vehicles for future carbon-free travel?

out, almost every VTOL design looks like some kind of scaled-up drone, with huge fans that blast downward to help create upward thrust. Jetoptera’s J-2000, however, is an entirely different beast. The aircraft looks like an Indycar or Formula One auto body mounted with rectangular thruster modules, with each thruster containing a “bladeless fan” system that Jetoptera has named the fluidic propulsion system(FPS).

 

Airbus taps Luminar to test how lidar could be used to make flying safer and autonomous

きょうは、Luminar社が、Airbusと協力してLidar(ライダー)と言ういわゆる距離測定装置を利用しての、自動航行航空機の開発に参入というような記事です。

 

Luminar Technologies is expanding its lidar business beyond automotive and into aviation through a partnership with Airbus. The collaboration with the French aerospace giant, which was announced Monday morning, marks the latest in a string of partnership announcements between Luminar and companies like Daimler, Volvo and Mobileye. Until now, these have exclusively focused on applying its light detection and ranging radar to automated vehicles on the ground — not in the skies.

The partnership won’t immediately bring lidar into commercial aircraft. Unlike Luminar’s deal with Daimler, Mobileye and Volvo this is not a production contract, although the aim is that it will lead to one. Instead, the partnership is with Airbus’ UpNext subsidiary, which is focused on developing and eventually applying new technological breakthroughs to aviation. The effort will be folded into Airbus Flightlab, an ecosystem that offers access to flight test platforms across Airbus’ business lines, including commercial aircraft, helicopters, defense and space. Luminar and Airbus will develop and test how lidar can be used to enhance sensing, perception and system-level capabilities to ultimately enable safe, autonomous flight, the companies said.

“We’re able to directly re-apply what we’ve accomplished for the automotive industry into aviation, an established nearly $1 trillion industry,” Luminar founder and CEO Austin Russell said in a statement Monday. “We believe that automation and safety enhancements will transform how we move across all modes of transport as we take our technology from roads to the skies. We look forward to accelerating our shared vision to define the future of flying.”

An F-16 fighter jet made an emergency landing Thursday night at Eugene F. Kranz Toledo Express Airport after its pilot reported engine trouble, an airport spokesman said.

Holly Kemler, a spokesman for the Toledo-Lucas County Port Authority, said the jet affiliated with the Ohio Air National Guard’s 180th Fighter Wing landed without incident after the pilot declared an emergency.

The emergency landing occurred about 10 p.m. Ms. Kemler referred further inquiry to the air guard base, whose spokesman was not immediately available for comment.

そこで、香港問題に鑑み、Englandも、遠方より中国包囲網を引こうと艦隊を差し向ける予定。

Hong Kong (CNN)The largest naval flotilla assembled by Britain in recent years will set sail in May on a months' long voyage through the Pacific, the country's Defense Ministry said Monday.
"When our Carrier Strike Group (CSG) sets sail next month, it will be flying the flag for Global Britain -- projecting our influence, signaling our power, engaging with our friends and reaffirming our commitment to addressing the security challenges of today and tomorrow," UK Defense Secretary Ben Wallace said Monday.
"The UK is not stepping back but sailing forth to play an active role in shaping the international system of the 21st century," Wallace said.
 
The strike group will be led by the aircraft carrier HMS Queen Elizabeth, marking its maiden deployment. The ship, one of the UK's two aircraft carriers, is the largest warship the UK has ever sent to sea.
