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 preparing a high-speed-test to demonstrate the open rotor’s fuel burn advantage.

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’s swept-airfoil composite prop, recently approved for the TBM 700/850.

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.

Hartzell Propeller’s “advanced swept airfoil” composite five-blade propeller for the Socata TBM 700/850 has received STC approval from both the FAA and EASA. The new design, specifically engineered for the TBM turboprop single, delivers faster takeoff acceleration, higher cruise speeds and better climb, as well as less noise, it said. According to Hartzell, the new propeller provides for a 100-feet-per-minute faster climb rate, while cruise is two knots faster than with the current four-blade propeller.

Raisbeck Engineering is now offering its swept-blade propellers for all King Air C90-series turboprop twins. Deliveries of the new blades, which sweep on both the leading and trailing edges, will begin in January. Blade quarter-chord sweep has been increased to 30 degrees at its outer diameter, and the propeller diameter has been lengthened by six inches, to 96 inches.
