French turboprop manufacturer Daher-Socata has signed a new five-year agreement with Hartzell Propeller to supply the recently introduced TBM 900 with advanced swept-airfoil composite five-blade propellers and spinners. “The TBM 900 is distinguished by its comfort, speed and efficiency, and all three are improved by Hartzell’s five-blade prop, which is quieter, speedier and more efficient,” said Nicolas Chabbert, senior vice president of Daher-Socata’s airplane business unit.
The FAA proposes to adopt a new airworthiness directive (AD) for certain Honeywell TPE331-5, -5A, -5AB, -5B, -10, -10R, -10U, -10UF, -10UG, -10UGR, and -10UR turboprop engines. It was prompted by engine propeller shaft coupling failures, leading to unexpected propeller pitch changes and resulting in high aerodynamic and asymmetric drag on the airplanes using these engines. This proposed AD would require removing from service certain part number propeller shaft couplings.
Cessna Aircraft subsidiary McCauley Propeller Systems is displaying its new Blackmac Carbon Series constant-speed propeller at this year’s Sun ’n’ Fun fly-in event in Lakeland, Fla. The world’s largest full-line propeller manufacturer expects to receive FAA certification in the first half of the year for the clean-sheet scalable design that features composite materials and uses a patented high-strength, low-weight continuous carbon loop blade retention system to reduce weight and improve product life.
The European Aviation Safety Agency STC’d Hartzell Propeller’s swept airfoil composite five-blade propellers on the Daher-Socata TBM 700/850. First installation of the new higher performance Hartzell prop on a European-registered TBM was recently performed at the Socata North America Service Center in Pembroke Pines, Fla. According to Hartzell, the new propeller for the turboprop single results in faster takeoff acceleration, higher cruise speeds and better climb, along with less noise.
Hartzell Propeller Inc. introduced two- and three-blade versions of its new scimitar-shaped Trailblazer propeller for experimental and certified aircraft during Sun’n Fun’s annual International Fly-In & Expo at Lakeland Linder Field in Florida this week. To celebrate the company is continuing its support of aerobatic performers at the show, including Sean D. Tucker, Michael Goulian, Matt Chapman, Team AeroDynamix, and the Paul McCowan Parachute Team.
Hartzell received FAA STC approval for its swept composite five-blade propeller for the Daher Socata TBM 700/850. Hartzell already has taken orders for the propellers and deliveries to TBM owners are expected to begin “shortly.” With the new propeller, the TBM’s takeoff acceleration from zero to 90 knots is 10 percent faster, climb rate is improved by several hundred feet-per-minute and cruise is increased by two knots. The five-bladed prop is also quieter, Hartzell said.
Snecma is about to carry out further tests on a one-fifth scale model of an open rotor engine, in a research and technology effort that epitomizes how laborious developing a new commercial engine concept can be.
Hartzell Propeller (Booth No. C7630) has witnessed the market for its aluminum–and, increasingly, carbon-composite–propeller blades and assemblies change markedly over the past five years as the global aviation industry continues a long and deliberate rebound from the recent global economic downturn. While it would be a stretch to say the shift was a welcome one for the Piqua, Ohio-based company, Hartzell executive vice president J.J. Frigge seems invigorated by the path his company has taken in the years since.
Raisbeck Engineering (Booth No. C7326) is highlighting its new swept-blade propellers for all King Air C90-series turboprop twins here at NBAA 2013. Deliveries of the blades, which sweep on both the leading and trailing edges, will begin in January. Raisbeck has been delivering swept blades for the King Air 200 series since the beginning of this year.
Hartzell Propeller received FAA and EASA type certificate approval for an advanced swept airfoil structural composite five-blade propeller for the TBM 700 and 850. The new design, specifically engineered for the TBM turboprop single, delivers quicker takeoff acceleration, higher cruise speeds and better climb, along with less noise.
