Savings of up to 40 percent on jet fuel for the Rolls-Royce 250 turbine-engine family? That is the prospect offered by Frontline Aerospace, said company CEO Ryan Wood in describing an emerging aviation technology called gas turbine recuperation.
When it issued Eclipse 500 Airworthiness Directive 2008-24-07, which becomes effective today, the FAA asked for comments from operators. The AD limits the Eclipse 500 to a maximum pressure altitude of 37,000 feet due to “several incidents of engine surge” of the jet’s Pratt & Whitney Canada PW610F-A engines. The surge is due to carbon buildup on the static vane during high bleed flow conditions.
Soloy Aviation has received FAA certification for its Soloy 206 Turbine Mk II, a Cessna 206H re-engined with a 417-shp Rolls-Royce 250-B17F/2 turboprop engine and fitted with a Hartzell three-blade prop with full beta reverse features. According to the company, the Mk II can climb at 2,460 fpm at sea level, cruise at 20,000 feet at 213 ktas, carry 775 pounds with full fuel and has an approximately 550-nm range.
Is it a jet? Is it a turboprop? That’s the question that remains after Socata confirmed here yesterday that it is still pursuing a twin-engine aircraft to augment its product line beyond the TBM 850 turboprop single. Company officials were tight-lipped about details, other than saying that the aircraft, codenamed NTx (NT for New Twin), will be bigger, faster and have two more seats than a TBM 850.
Pratt & Whitney Canada’s prospects in the business jet and general aviation markets remain bright despite the air of economic uncertainty stemming from the U.S. investment industry crisis, according to senior company officials.
A Jan. 20, 2007 incident over the English Channel resulted in the UK’s Air Accidents Investigation Branch (AAIB) recommending the FAA mandate operators adhere to a service bulletin Honeywell issued subsequently in late 2007.
