Pascal Chrétien, the designer and pilot of an electric rotorcraft that flew in 2011, is forming a company that aims to offer hybrid power for aircraft, notably helicopters. The patented technology is called Tetraero, and according to its promoters its main benefit would be in safety.
Rolls-Royce and Scott’s Bell 47 (SB47) have signed a memorandum of understanding to explore installing the RR300 turboshaft in the SB47 multipurpose light helicopter. Scott’s acquired the type certificate for the Model 47 from Bell Helicopter in 2010 and is currently supporting the helicopter and offering complete refurbishment and updates for the aircraft. The company’s ultimate goal is to place the helicopter back into production. An STC installation of the Rolls-Royce 250 in Bell 47s has been available since the 1970s.
The diesel engine demonstrator aiming to replace turboshafts in light helicopters, which could cut fuel burn by about 30 percent, is said to be on track for installation and ground tests on a Eurocopter EC120 in the first quarter of 2014. Some components have been tested in laboratories and critical design reviews conducted last week were successful, according to project officer Sébastien Dubois.

In another safety issue affecting the Sikorsky S-92 helicopter’s main gearbox, on July 18 the FAA released an airworthiness directive (AD) that calls for inspection for cracks. The AD was prompted by the discovery of a crack in the gearbox housing of one S-92, “in the cored passage area adjacent to the scissor bracket mount,” allowing oil to leak. The result could be a loss of oil and subsequent failure of the gearbox, the FAA said.
Austro Engine (Outside Exhibit 18), part of the group that owns Austria’s Diamond Aircraft, is exhibiting its new diesel and rotary engines for light aircraft and drones at the 2012 Farnborough International Airshow.

Turbomeca subsidiary Microturbo (Stand 1543) has completed the first flight tests of its new auxiliary power unit (APU) for the AgustaWestland AW189 helicopter. In-flight start has been demonstrated already, and the test unit has also successfully restarted one of the main engines in flight. “The e-APU60 is performing accordingly with our ambitious goals,” said Pierre-Yves Morvan, Microturbo’s CEO.
Pratt & Whitney Canada’s PW210 turboshaft has been selected to power the Eurocopter X4 medium twin, which is slated to replace the AS365/EC155 Dauphin series. Entry into service is pegged for 2017. The PW210S, a variant produced for the Sikorsky S-76D medium twin, was certified in 2011. AIN understands the X4 will be offered with two engine options, the other choice coming from Turbomeca.
