A glider sets new altitude record

The Perlan-2 glider yesterday set a new altitude record, reaching an altitude of more than fourteen miles.

Then on September 2, Perlan pilots Jim Payne and Tim Gardner strapped themselves in and rode the glider to an altitude of 76,000 ft (23,000 m), setting a new flight record. This is higher than Lockheed Martin’s jet-powered U2 spy plane flown by the CIA, which reached 73,700 ft (22,475 m), and places it amongst a handful of manned aircraft to sustain flight at such as altitude.

Implied but unstated in the article at the link is the military value of this technology, once combined with drone technology.

World’s largest jet engine makes first test flight

The world’s largest jet engine, built by GE Aviation for Boeing’s next generation wide body passenger jet, made its first test flight last week.

The GE9X is a monster compared to its predecessors. Due to the extensive use of composites in building the fan blades and the fan case, 3D-printed nozzles, new light- and heat-resistant ceramics, and reducing the number of fan blades from 22 to 16, GE was able to lighten the engine and expand its size so that its fan is now 134-inches (341 cm) across and the entire engine is as wide as a Boeing 737 fuselage. In addition, it can push 100,000 lb of thrust and is 10 percent more efficient than the GE90 engine used on the current generation of 777s.

The engine was attached to a 747 test plane for the flight, and the images at the link truly illustrate how large this engine is. The 747 still had its two outer normal engines attached, and the size difference is gob-smacking. When I first looked at the pictures I was convinced it was fake and that they had photoshopped this giant engine onto the 747. They didn’t.

Private commercial supersonic jet gains funding

A private commercial supersonic jet company, Boom Supersonic, has gained significant investment funding since it first revealed its design concept in March.

Boom, whose suppliers include General Electric Co, Boeing, Honeywell International Inc and Netherlands-based TenCate Advanced Composites, has reportedly received 76 pre-orders from airlines, excluding the option of up to 20 aircraft from Japan Airlines. As of March 2017, the firm had raised about $41 million (Β£30.5 million) in funding.

Yoshiharu Ueki, president of Japan Airlines, added: ‘Through this partnership, we hope to contribute to the future of supersonic travel with the intent of providing more “time” to our valued passengers while emphasising flight safety.’

The firm has previously revealed that initial test flights for its 1,451mph (2,330kph) aircraft, nicknamed ‘Baby Boom’, will begin by the end of 2018.

Including the JAL preorder that makes 96 airplane sales total. It appears that this company is increasingly for real.

United flies its last 747

United yesterday completed its last scheduled 747 passenger flight, ending a period lasting almost a half century since the first 747 took off.

The flight had a 1970s theme, with the crew in vintage uniforms and the passengers dressing in costumes invoking that time period.

The article does a nice job of recounting the 747’s history, as well as why it is being replaced. It also noted this:

[T]he aircraft would go on to defy all expectations. Boeing anticipated it would become obsolete before the Nineties, believing that supersonic jets would overtake conventional aircraft.

In fact the 747 is still in production with current orders placed by a number of developing countries which will potentially see it serving into 2030. While the aircraft’s life is limited in the US – with Delta the only airline still flying the craft and due to retire it later this year – other major carriers will continue operating it well into the next decade. British Airways, which now operates 36 of the aircraft, more than any other airline, has confirmed it will be phasing it out – but will not part ways with it entirely until 2024.

Even once it has disappeared from passenger routes, it is expected the 747 will go on to serve many more years as a cargo plane.

The final commercial 747 flights

Link here.

United announced Monday that its final Boeing 747 flight will take place Nov. 7 with a celebratory recreation of its first United flight from San Francisco to Honolulu.

Twenty-eight minutes later, at 3:47 p.m. Monday, Delta announced that it recently operated its final Boeing 747 Tokyo Narita-Honolulu flight (on Sept. 5), and that it had operated what were thought to be the final domestic 747 flights from Honolulu to Los Angeles to Detroit. Delta subsequently used two 747s on Orlando evacuation flights as Hurricane Irma approached, bringing a widely-applauded end to its domestic 747 flying.

United plans to recreate the 1970 San Francisco-Honolulu flight, its first commercial Boeing 747 flight, on the Nov. 7 flight. β€œFrom a 1970s-inspired menu to retro uniforms for flight attendants to inflight entertainment befitting of that first flight, passengers will help send the Queen of the Skies off in true style,” United said in a press release.

Though the plane has been bypassed by newer technology, I suspect that we will see 747s flying for many years to come, but only in specialized situations. It was a grand achievement, and proved that giant planes could be built.

Near disaster at San Francisco airport

An Air Canada plane preparing to land in San Francisco almost smashed into four planes on the ground when the pilot mistakenly aimed for the parallel taxiway rather than the runway itself.

In what one aviation expert called a near-miss of what could have been the largest aviation disaster ever, an Air Canada pilot on Friday narrowly avoided a tragic mistake: landing on the San Francisco International Airport taxiway instead of the runway.

Sitting on Taxiway C shortly before midnight were four airplanes full of passengers and fuel awaiting permission to take off, according to the Federal Aviation Administration, which is investigating the β€œrare” incident. An air traffic controller sent the descending Air Canada Airbus 320 on a β€œgo-around” β€” an unusual event where pilots must pull up and circle around to try again β€” before the safe landing, according to the federal agency.

FAA investigators are still trying to determine how close the Air Canada aircraft came to landing and potentially crashing into the four aircraft below, but the apparent pilot error already has the aviation industry buzzing.

This would have been the ultimate in pilot error, and might end the career of that pilot.

Maiden flight of China’s new 158-seat C919 passenger jet

China’s answer to Boeing and Airbus’s domination of the aviation business, a 158-seat passenger jet dubbed C919, is due to make its maiden flight later this week.

According to Xinhua, the first flight of the C919, assembled by state-owned Commercial Aircraft Corporation of China (Comac), will be conducted at the Shanghai International Airport on Friday, but could be delayed if weather conditions are not suitable. The timing for the first flight was set after the passenger jet passed a thorough assessment in April.

A successful maiden flight, followed by a series of safety certification processes, could open a floodgate for new orders for the single-aisle passenger jet, likely to generate 1 trillion yuan (HK$1.13 trillion) in business for Comac, according to Galaxy Securities. The C919 has received 570 orders and commitments from 23 customers, mainly Chinese state-owned carriers and leasing companies.

The plane is three years behind schedule. And while much of it is Chinese-made, a considerable percentage of major parts are produced by U.S. and European manufacturers.
