Airbus Helicopters will lead the design of a compound rotorcraft demonstrator dubbed “LifeRCraft” (low-impact, fast and efficient rotorcraft) as part of Europe’s recently launched Clean Sky 2 Joint Technology Initiative. The LifeRCraft architecture combines a main rotor for vertical takeoff and landing, fixed wings for energy-efficient lift and open propellers for speed. The company will use experience gained on its X3 compound demonstrator between 2010 and 2013.
Sikorsky (OE3, OE4) here on Monday announced that it has begun delivering S-76 medium twin helicopters equipped for executive transport and search-and-rescue (SAR).
Among the features that executive transport operators will enjoy, the company said, is the ability to keep the rotors static, i.e. not rotating, while running an engine to power the air-conditioning. It also claims its active vibration control and Quiet Zone transmission technology provide smooth and quiet cabin conditions, allowing normal conversations.
Airbus Helicopters will lead the design of a compound rotorcraft demonstrator dubbed “LifeRCraft” (Low Impact Fast & Efficient RotorCraft) as part of Europe’s Clean Sky 2 Joint Technology Initiative, which was formally launched last week in Brussels. Preliminary studies, architecture and specification activity will start this year, with development and testing of components and subsystems envisioned in the 2016-2018 timeframe. Flight evaluations could start in early 2019.
Russian Helicopters is stepping up efforts to strengthen its base of international partners. The move is in part driven by the fact that it can no longer count on Ukrainian engine suppliers Motor-Sich and Ivchenko-Progress in the wake of ongoing political tensions.
Powered ground tests of the Sikorsky CH-53K, the U.S. Marine Corps’ future heavy-lift helicopter, are now well under way at the company’s West Palm Beach, Florida facility in the run-up to first flight later this year. The first ground-test vehicle (GTV1) started systems testing in late April, about a week before the first flying article was rolled out on May 5. Operational service of the mostly composite helicopter, which has been dubbed the “King Stallion,” is expected in 2019.
Sikorsky Aircraft powered on its S-97 Raider prototype on May 28 at the company’s development flight center in West Palm Beach, Florida, marking the successful installation of the avionics system and a major step toward completing the assembly of the new light tactical rotorcraft. A contender for the U.S.
Consumer electronics manufacturers, former toy and hobby suppliers, research university spinoffs and major aerospace companies are among the entities vying for a share of the simmering commercial market for small unmanned aircraft systems (UAS) generally weighing less than 20 pounds. They are advancing numerous fixed- and rotary-wing designs, some of which were displayed at the Unmanned Systems 2014 conference in May and others elsewhere. Following is a description of some, although by no means all, of the recent showings:
The first Bell 525 Relentless super-medium twin helicopter is moving closer to final assembly at Bell Helicopter’s plant in Amarillo, Texas. Matt Hasik, Bell’s senior vice president of commercial programs, told AIN that the three main cabin sections will be joined within the next few weeks. He also said that the first carbon-fiber, all-composite main rotor blade for the 525 has been completed and is undergoing testing.
Marenco Swisshelicopter is still preparing to fly its SH09 SKYe single-turbine helicopter. The company is finalizing testing of the major systems, a spokesman told AIN. “We have done a number of trials on the aircraft,” he said. In addition, the “whirl tower” test bench is running at full speed with the main rotor head and gearbox. Certification of the 5,840-pound-mtow rotorcraft is expected in the second half of next year.
Sikorsky and Lord have completed the flight demonstration of a hub-mounted vibration suppressor (HMVS) intended to address crew fatigue and reduced equipment reliability caused by helicopter vibration. Eventually, the HMVS could be part of a larger system integrated into all Sikorsky helicopters.
