How fast does a rescue helicopter fly

Types of missions: Accident response 96; Neonatal and pediatric emergency 22; Medical emergency; Urgent interhospital transfer 89; Police support 3, Search and rescue Cruising speed: kmh. People helped: Types of missions: Neonatal and pediatric emergency ; Urgent interhospital transfer ; Urgent accident victim transfer Life Flight: It takes just 10 minutes for the live-saving helicopter to be in the air. Virginia Fallon , Dec 28 John Nicholson. Harry Stevenson has been a Life Flight rescue helicopter pilot for 14 years but, despite his experience, says he's still quite capable of being surprised on the job.

Life Flight Chief Executive Mark Johnston says its team work - that of the emergency workers and the public who donate to the service - that saves lives. The engine Sikorsky ended up choosing for the X2, an LHTEC T turboshaft, is a modern, state-of-the-art design that might well serve for a production vehicle.

The rotors, propeller, and engine are coupled together with gearboxes and shafts. The X2 prototype made its first test hop on 27 August , in Elmira, N. Several more low-speed flight tests also went off without a hitch. To venture to higher speeds, Sikorsky sent the test team to its flight center in West Palm Beach, Fla. On the day of that flight, in August of this year, the test team got started at the crack of dawn.

To ensure that the pilots would be flying in smooth air, the crew had to be on site by a. The crew rolled the aircraft out onto the runway, where a dozen safety officers in bright orange jumpsuits and noise-canceling headsets were on patrol.

Two chase vehicles were there to observe the test flight—another helicopter and a fixed-wing turboprop. The latter would be needed to keep up with the X2 as it accelerated to higher speeds. The test team was on high alert as it orchestrated flight activities to keep the three vehicles a safe distance apart. Cheers and applause broke out on the ground. The pilot slowed the X2, turned it around, and flew back to land on the runway. Everyone involved was jubilant, but most of all relieved—especially the pilot.

The real X2 has only about 14 flight hours on it, but its engineers and pilots have spent hundreds of hours flying the simulator. Assuming all goes well, Sikorsky engineers are planning to adopt some of the technologies used on the X2 for the new helicopters they have on the drawing board. So expect some dramatic shifts in the way helicopters are designed.

Thomas Lawrence, a technical fellow at Sikorsky Aircraft Corp. First he helped design an airship lifted by four conjoined helicopters.

Next came the XHA, a futile effort to break the helicopter speed record. He then focused on the X-Wing, an aircraft that could take off like a helicopter but switched midair to fly like a fixed-wing airplane.

None succeeded. See the Back story on this article. Craig S. China has taken another step toward semiconductor independence with Alibaba announcing the design of a 5-nanometer technology server chip that is based on Arm Ltd.

But, impressive as that feat is, an even more significant chip design development by the Chinese tech giant may be making available the source code to a RISC-V CPU core its own engineers designed. This means other companies can use it in their own processor designs—and escape architecture license fees. The company made both announcements at its annual cloud convention in its home city of Hangzhou last month.

The Chinese government is funding a lot of startups that are designing a variety of chips. The number of newly registered Chinese chip-related companies more than tripled in the first five months of from the same period a year ago. And the biggest Chinese technology companies like Alibaba, Baidu, and Huawei are developing their own chips rather than banking on those from Intel, Nvidia, and other United States-based companies.

China is intent on developing semiconductor independence, both in design and manufacture of state-of-the-art chips.

The urgency for doing so has been helped along by U. The sanctions extend to any Huawei suppliers that use U. The United States, alarmed at China's campaign to bring Taiwan under its control, has also begun an ambitious program to 'reshore' its semiconductor manufacturing after allowing much of it to migrate to Taiwan. Around 80 percent of the world's semiconductor production capacity is in Asia, and nearly all the most advanced logic chip production is in Taiwan. No Chinese semiconductor foundry has yet achieved the 5-nanometer processing needed to make Alibaba's new ARM-based chip, so it is still beholden to Taiwan for manufacturing.

But the implications of Alibaba's general choice of Arm and RISC-V instruction set architectures is perhaps more consequential for the long term. An instruction set architecture, or ISA, is the language in which software talks to hardware, and thus determines the kind of software that can run on a particular chip. Most servers use CPUs based on Intel's x86 instruction set architecture. But UK-based Arm, which licenses its instruction set architecture to chip designers, has been gaining a foothold in this market.

RISC-V, which refers to the fifth generation of an open-source reduced instruction set computer architecture created by U. This past June, China hosted the fourth annual RISC-V summit, bringing together industry, academia, and government to talk about the future of the architecture. In the wake of the U. Unable to buy Intel chips because of the sanctions, Huawei most recently sold its x86 server unit to a company owned by China's Henan province.

From the beginning, the company indicated that it intended to open the CPU's source code—the hardware description language that describes the structure and behavior of the CPU core's electronic circuits. It has now done so… with little fanfare.

Its Yitian server system on a chip SoC , manufactured by Taiwan's TSMC, will have a total of Arm-based cores, with 60 billion integrated transistors and a top clock speed of 3. Alibaba said it is the first server processor compatible with the latest Armv9 architecture.

Alibaba said the SoC achieved a score of in SPECint a standard benchmark for measuring CPU integer processing power , surpassing that of the current state-of-the-art Arm server processor based on Armv8 by 20 percent in performance and 50 percent in energy efficiency. The company also announced the development of proprietary servers, under the brand name Panjiu , developed for the next-generation of cloud-native infrastructure.

By separating computing from storage, the servers are optimized for both general-purpose and specialized AI computing, as well as high-performance storage. The company vowed to provide more services and support for RISC-V development tools, software development kits, and customized cores in the future. Consultant Gwennap suggests that Alibaba's Arm and RISC-V efforts are experiments more than commercial endeavors, noting that Alibaba is still using x86 Intel chips for the vast majority of its internal use.

Alibaba's new Arm-based server chip will be used in Alibaba datacenters to provide cloud services to customers.. The company will continue to offer Intel-based services, so it's up to customers to choose Arm over xbased chips.

When Amazon did something similar a few years ago, there was little uptake for the Arm-based chips. But true semiconductor independence will require China to develop its own extreme ultraviolet lithography machines , required to etch microscopic circuits on silicon. SMIC , China's main chip foundry, can't provide anything smaller than 14 nm. SMIC claims to have mastered the 3nm chip process in the lab and is trying to buy the EUV lithography machines necessary for production from ASML, the Dutch company that currently has a monopoly on the critical equipment.

But the United States is intent on blocking the sale. But getting that technology out of the lab and into a machine remains many years away.
