On the heels of a Service Bulletin, the FAA has issued Airworthiness Directive 2007-26-12 focusing on Robinson R22 and R44 main rotor blade delamination.
French-based Hélicoptères Guimbal received EASA certification for its Cabri G2 light piston single. The two-seater will compete with the ubiquitous Robinson R22. Because Eurocopter has supported designer Bruno Guimbal, the Cabri shares some technical similarities with Eurocopter rotorcraft such as the shrouded tail rotor.
Jimmie Leroy Shriver, 53, of Summersville, Miss., was sentenced by U.S. District Judge Dean Whipple last month to spend nearly 13.5 years in federal prison without parole for shooting at and hitting a Missouri Guard Sikorsky UH-60 Black Hawk. The court also ordered Shriver to pay more than $11,000 in restitution to repair damage to the helicopter. Shriver was arrested on Sept.
That new aircraft are often derived from earlier models is no surprise, but hybrids of two separate bloodlines are rare. The Eurocopter EC 145 medium twin, derived from the venerable BK 117 and the much newer EC 135, is one such hybrid. But unlike many mergers, particularly in the corporate world, this one actually works.
In the face of what market forecasters predict will be nearly another full decade of flat civil helicopter sales, manufacturers have been loath to risk precious capital to develop models whose market reception would likely be less than enthusiastic. The result has been a handful of new designs, some riskier than others. Herein, the details…
I have to admit that the Robinson revolution passed me by. I graduated from flight school in the U.S. Army in 1978, the year before the first R22 was certified. After seven years in the army, my civilian career path led directly to multi-engine turbine helicopters, a world apart from single-engine pistons.
Airwolf Aerospace, a provider of firewall-forward accessories, has been awarded an FAA STC that the company claims will permanently prevent leading-edge skin delamination on Robinson R22 and R44 helicopter main rotor blades.
Rotorcraft design has reached a plateau and advancements are taking place in incremental steps rather than as major breakthroughs. That was the prevailing message of a day-long workshop about the past, present and future of rotorcraft held at the University of Maryland’s Alfred Gessow Rotorcraft Center.
Archrivals AgustaWestland and Eurocopter will join forces on a major environmental research program that will include integration technology demonstrators (ITDs) for a greener helicopter. The project–part of the larger E1.6 billion ($2.2 billion) Clean Sky Joint Technology Initiative–is expected to yield innovations such as smart blades for the main rotor and electric drive for the tail rotor.
As the month of May came to a close, a team of Boeing engineers were putting the finishing touches to a one-of-a-kind flying machine at an outpost of that company’s “Phantom Works” just outside the sun- and sand-blasted southwestern Arizona town of Yuma.
