Raisbeck Engineering has started FAA certification flight-testing of its new Hartzell composite five-blade swept propeller mod for the Beechcraft King Air 350 series. The Raisbeck/Hartzell team completed all ground and flight vibration and governor output pressure testing early last week before clearing the aircraft for flight-testing, which is expected to be completed by month-end. The new King Air 350 propellers will be formally introduced at the NBAA Convention next month in Orlando, Fla., where more details and preliminary performance improvements will be released.
Piaggio Aero’s new Avanti Evo aircraft is making its first appearance outside Europe this week at the LABACE show. The new model has been designed to deliver improved performance and a quieter ride–both inside and out–compared with the existing Avanti II twin turboprop. The Evo is being shown here at Congonhas Airport in the static display area of the Italian airframer’s Brazilian distributor Algar Aviation.
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 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.
Hartzell Engine Technologies (Booth No. C7630) has been selected to supply the alternator for the $1.96 million Cirrus Aircraft SF50 Vision single-engine personal jet. Hartzell will provide its 140-amp ES-6904 model for the aircraft.
Hartzell Engine president Mike Disbrow said the company worked closely with Cirrus and engine maker Williams International “to meet the electrical power requirements of the SF50’s systems and advanced avionics.” Williams is providing its 1,800-pound thrust FJ33-5A engine for the jet.
Two companies under the Hartzell product umbrella announced significant developments at NBAA’12.
