Based in the location that gave birth to powered flight, DARE Medflight shows us how they manage to keep their county safe with their forward thinking approach to HEMS.

Dare County, nestled into the corner of beautiful and historic northeastern North Carolina, resides along the Atlantic seaboard. Formed in 1870, Dare County is named in honor of Virginia Dare, the first child born of English parents in America. The county stretches along nearly one-hundred-ten miles of shoreline in an area best known as the Outer Banks. Manteo, the county seat, lies just ninety miles to the south of Virginia Beach, and serves as the base for Dare Medflight, operating out of Dare County Regional Airport.

With a permanent population of approximately 33,900 people, the task of providing helicopter emergency medical services (HEMS) over such a large area would look —to the outsider— to be a fairly uneventful task in such a sparsely populated area. The county’s tourism industry, however, results in quite a large seasonal population. Between the months of June and August, Dare County is home to an estimated 225,000 to 300,000 people. One of the many tourist attractions that draws people to beautiful Dare County, NC, is the First Flight Airport. This little aerodrome, located in Kitty Hawk, is known also as the birthplace of aviation. It is the iconic place where the Wright Brothers took to the skies in the first powered airplane flight on December 17^th, 1903. Today, not far from that very beach, there lies a

Editor’s note: In the run-up to the 19th National Congress of the Communist Party of China, China Daily will cover a series of key projects and advanced equipment of national importance, showcasing the country’s huge improvements and relentless efforts in manufacturing upgrading and innovation.

The C919 aircraft, China’s first homegrown large passenger jet, boasts a global sourcing model that is similar to that of Boeing Co and Airbus Group SE. The model is believed to increase production efficiency and save costs, but aircraft manufacturers retain control of key technologies.

The C919 plane also has several significant technical breakthroughs. Intense research and development was conducted before production, and it uses a large amount of composite materials.

For instance, 85 percent of its tail section is made from composite materials, according to Commercial Aircraft Corp of China Ltd, manufacturer of the C919. In China, the technology to apply composite materials is still in its infancy, and the application requires mould manufacturing, temperature control and other techniques.

Harbin Hafei Industry Co Ltd, an aviation manufacturer in Harbin, Heilongjiang province, is mainly responsible for the manufacturing of some parts that mainly use composite materials, including the hatch door for the front landing gear and the main landing gear, as well as the vertical tail of the C919.

Li Wei, deputy chief engineer of the C919 project at Hafei, said: “We cooperated with Boeing, Airbus and Embraer before. The design capabilities, quality system, and the supplier management

It is May 10, and Ray Evernham, still two weeks away from becoming NASCAR Hall of Famer Ray Evernham, looks over his glasses and raises his eyebrows to emphasize his seriousness. “We’ve known each other a long time, and I’m telling you, these people are all-in on NASCAR. They are really worried about getting the racing part right.”

Evernham isn’t sitting in the headquarters of an auto manufacturer or a potential team sponsor. He’s in the common area of Pixar Studios — part of the Walt Disney Company, as is ESPN — a massive space tucked into the Oakland side of the Bay Area, a building personally designed by Apple founder Steve Jobs. The front door is guarded by a sculpture of the Incredibles and a trophy case full of Oscars.

As Pixar tradition demands, the walls are covered in concept art for the studio’s upcoming big release. The current showcase is “Cars 3,” which hits theaters Friday. On one wall, a massive mural depicts the familiar red frame of Lightning McQueen racing down a beach that looks an awful lot like Daytona. On another, the Fabulous Hudson Hornet powerslides around a dirt track that looks an awful lot like the old Occoneechee Speedway.

The whole place looks an awful lot like NASCAR heaven.

“It reminds you of my other office, doesn’t it?” Evernham said, referring to the HQ of Hendrick

Boeing expected to fly its third 787-10 prototype just around the time of this year’s Paris Air Show, completing a series of first flights that started in March with Rolls-Royce Trent 1000-powered ZC001 taking off from the company’s factory grounds in North Charleston, South Carolina. Speaking with reporters just ahead of the show, Boeing 787-10 chief program engineer Wayne Tygert called the first example—on display here at the show—one of the company’s leading airplanes in terms of quality, translating into “very little if any [traveled work], and no “squawks” during any of the early flight test missions.  

Tygert reported that Boeing finished flutter testing on ZC001 on May 31, and that the company planned to start autoland testing on the second airplane—the GEnx-1B-powered ZC036—during the first days of June. Apart from autoland and flutter, ZC001 tests stability and control, avionics, propulsion and the primary flight control system (PFCS) Along with stability and control and flutter, GEnx-1B-powered ZC036 tests performance and aircraft maintenance manual (AMM) validation.

The third airplane—another Rolls-powered example, designated ZC002—will test performance and systems, such as the environmental control system (ECS), as well as performance and the AMM. Now having completed low-speed flight control system testing, Boeing has already progressed through 20 percent of the program, putting it on schedule for what Tygert called the bulk of the testing by the end of the year.

“So far we are essentially seeing what we expected,” he said. “Our

The aerospace industry is often associated with large scale simulations of an entire aircraft or complex parts. As the industry strives for ever-improving performance, it is now optimising at every level – including the components that make up such massive structures.

Such large-scale models of an entire aerospace system are traditionally developed at the onset of the system design process, as Richard Yen, senior vice president for global markets at Altair, explained: ‘These models are focused on simulating the overall system response to all of the intended or expected operating conditions. As these models are refined and developed, aerospace companies have very robust and tested methods to transfer the loads from the system model to an individual component where a much more detailed analysis can be performed.’ 

There is a high demand for such simulation and modelling of components as the aerospace industry strives to offer continued, improved performance across a range of factors including weight reduction, power management and drag. Rob Harwood, global industry director at ANSYS, explained: ‘The margins for performance increase at all levels in the supply chain are so marginal today that the easy improvements are long gone.’

‘Finding the sources of additional improvement is very, very difficult and simulation is a key technique to rapidly and cost-effectively explore new ideas – even what might appear as simple components such as the bracket on a seat are now being optimised topologically for additive manufacturing, so that they can further reduce weight,’ Harwood added.

The huge variety of parts to simulate
