Helicopter engine manufacturer Turbomeca (Booth No. 2814) is exhibiting a mockup of its Arrius 2R for the Bell SLS and has a variety of ongoing developments. The company is also considering the launch of a new family of turboshafts to power medium-heavy to heavy rotorcraft. Meanwhile, deliveries are on a downward curve.

News and issues regarding all manner of civil and military rotorcraft powerplants.
Busy times for helicopter manufacturers bringing new rotorcraft to market are keeping engine maker Pratt &Whitney Canada (P&WC) busy as well. Among the new turboshafts approaching certification is its PW210A engine for AgustaWestland’s new AW169 twin. At the same time, the PT6C-67E will soon be powering the service entry of the new Airbus Helicopters EC175.
The diesel engine research and development project that Airbus Helicopters (formerly Eurocopter) is conducting with racing car engine specialist Teos Powertrain Engineering and engine manufacturer Austro Engine, under Europe’s Clean Sky joint technology initiative, has cleared significant milestones. The demonstration engine is now being tested on an iron bird, before the first flight planned for this year on a modified EC120.
Russian Helicopters announced that the third prototype of the Mi-38 heavy twin, and the first fitted with Klimov TV7-117V engines, made its maiden flight on November 29 at the Mil Moscow helicopter plant. The helicopter’s new Fadec-controlled turboshaft engine outputs 2,800 shp at takeoff and up to 3,750 shp in “emergency power.”
Helicopter engine manufacturer Turbomeca announced that the Ardiden 3C/WZ16, which was jointly developed with China’s Avic Engine, made its first run at the French firm’s test facility in Bordes in southwest France. The successful ground test confirmed the turboshaft engine’s aeromechanical behavior and performance, according to Turbomeca.
The EASA has approved the interim solution Eurocopter devised to address concerns about main-gearbox lubrication on the EC225 after two controlled ditchings last year.
The manufacturer is using vibration monitoring, inspections and part modification to prevent the possibility of an undetected crack leading to in-flight rupture of the bevel gear vertical shaft–a part that is critical to main gearbox lubrication.
GE’s 2,000-shp CT7-2E1, the powerplant for the twin-engine AgustaWestland AW189, received FAA certification last week. The CT7-2E1 is the latest civil-certified addition to the CT7/T700 line, with Fadec and what GE describes as a state-of-the-art hot section for power and reliability. The first production-certified CT7-2E1s will be delivered to AgustaWestland this month, GE said.
The Tech 800 core engine demonstrator made its first run last month at Turbomeca’s Bordes, France headquarters, the company announced last week. A high-pressure spool for the 1,100-shp engine class, the Tech 800 is a precursor to the engine manufacturer’s TM800 Arrano. The Arrano turboshaft will power the Eurocopter X4 medium twin, a Dauphin successor planned for 2017.
During a press conference at last week’s Heli-Expo convention in Las Vegas, Kamov general designer Sergei Mikheyev dropped something of a bombshell when he revealed that the Kamov Design Bureau had produced the initial conceptual design for China’s Changhe (CAIC) Z-10 attack helicopter. Having made its public debut at last year’s Zhuhai airshow, the Z-10 is in the early stages of production and has entered service with at least one Chinese army unit.
Enhanced performance, greater reliability and reduced operator maintenance costs are the primary selling points behind the “Mercury Mod” starter generator upgrade offered by Naasco Northeastern Corporation. In addition to celebrating the 18-year history of the upgrade, Naasco is sharing news about its upcoming “Mercury Mod-Phase Two” variant at Heli-Expo’13 (Booth No. C3924.)
