More than 4,000 sq ft of Duncan Aviation’s new 175,000-sq-ft hangar in Lincoln, Neb., is dedicated to engines. “We’ve been in the new shop for only a few months but have already experienced a significant increase in work efficiency and improvement to the safety of our customers’ property,” said James Prater, manager of turbine engine services. “Before the move, all engines and their components would remain subject to being moved in the hangar.
While ATR and Bombardier continue to vacillate over plans to introduce a new 90-seat turboprop, Pratt & Whitney Canada keeps moving forward with an engine it believes will deliver a 20-percent fuel burn improvement over existing engines in the 5,000- to 7,000-shp range by the turn of the decade. Dubbed the Next Generation Regional Turboprop (NGRT), the engine would feature an all-new compressor, a miniaturized version of Pratt & Whitney’s patented Talon combustor and likely an eight-blade propeller
The firm started in 1999 as the HVLS Fan Co., an acronym for high-volume low-speed fans. That name accurately described the design and efficiency of the company’s products, but after three years in business, according to the Lexington, Ky.-based manufacturer, “we finally had to bow to the sentiments of our customers and concede that we do, in fact, design and manufacture some Big Ass Fans.” Hence, the current brand name.
Dallas Airmotive unveiled its new logo here at NBAA 2013. Using the company’s traditional red and blue colors, the new logo morphs spinning turbine engine blades into the shape of a Phoenix.
On September 12, Europe’s EADS unexpectedly assigned a schedule and a market segment to its “E-Thrust” hybrid propulsion concept, which was revealed at the Paris Air Show this year with Rolls-Royce. The “E-Airbus,” under its new moniker, is to enter into service in 2030 as a regional aircraft, probably a 70- to 100-seater. The announcement came during a conference organized by the French government in Paris about its industrial policy.
CFM International claims it is behind a revolution in the use of advanced materials for its Leap series of engines for single-aisle aircraft, that gives it a durability and maintainability edge over the competing Pratt & Whitney PurePower geared turbofan.
Embry-Riddle Aeronautical University in Prescott, Ariz., will incorporate five turbofan components from previously repaired engines, a donation from Snecma America Engine Services (Sames), into its aerospace and mechanical engineering programs.
The donated items (a fan shaft assembly, thrust bearing, compressor rotor shaft, fuel manifold ring and high-pressure turbine rear shaft) came from a CFM56-5A, the engine that powers single-aisle aircraft such as the Airbus A319 and A320. The components will help expand engineering students’ understanding of turbine engines.
Many cockpit crewmembers believe the ingestion of ice crystals by a jet engine is essentially harmless if the engine’s igniters are turned on. However, aeronautical engineers generally do not agree, citing incidents when mixing ice with standard intake air resulted in a noticeable reduction in engine power output and, at its worst, a complete engine flameout. Ice formation inside an engine compartment can also lead to indicator anomalies that may not shut down the engine, but may lead to air data system failures.
The FAA has issued a supplemental notice of proposed rulemaking revising an earlier proposed airworthiness directive for Cessna 525 Citations equipped with certain part number air conditioning compressor motors. The NPRM proposed to require inspection of the number of hours on the A/C compressor hour meter, inspection of the logbook and replacement of the brushes on specified compressor motors or deactivation of the A/C system until replacement of the brushes.
Pascal Chrétien, the designer and pilot of an electric rotorcraft that flew in 2011, is forming a company that aims to offer hybrid power for aircraft, notably helicopters. The patented technology is called Tetraero, and according to its promoters its main benefit would be in safety.
