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.

Snecma plans soon to start another phase of open-rotor engine testing using a one-fifth scale model, in a research and technology effort that epitomizes how laborious developing a new commercial engine concept can be. The concept, based on contra-rotating high-speed propellers, may not find itself in service before 2025. Nevertheless, trials aimed at cutting noise while retaining the huge efficiency advantage of the open rotor’s architecture are well under way.

Raisbeck Engineering has come to LABACE to show off its new swept-blade turbofan propellers for the Beechcraft King Air 200 family. The new propellers received certification from the Brazilian civil aviation authorities in June and last month the European Aviation Safety Agency granted its approval as well.

Raisbeck Engineering’s swept-blade propellers for 200-series King Airs have been certified by the EASA, adding to a previous FAA approval. Thanks to a higher blade sweep and increased propeller diameter, the new propellers provide for quieter operation and increased thrust, according to Raisbeck. They provide more than 1,090-feet improvement in published FAA takeoff performance compared with the OEM propellers, Raisbeck said. Deliveries of production swept-blade propellers began in the U.S. in March.

The new short takeoff and landing Antonov An-70 military transporter will soon complete joint state testing, according to Dmytro Kiva, Antonov president and general designer and academician of the National Academy of Sciences of Ukraine. The An-70’s noise certification has been issued, he added.

Raisbeck Engineering’s swept-blade “turbofan propellers” for the King Air 200 series are now approved in Brazil after the Brazilian National Civil Aviation Agency (ANAC) granted certification late last month.

A spokesperson for Raisbeck Engineering told AIN, “There are about 500 King Airs in Brazil alone, making it a major market for us. We hope that the swept-blade prop reenergizes our presence in the South American region and we’ll be focusing a lot of our attention on the market as it continues to grow.”
