At its booth here at NBAA 2014, Timken is highlighting its parts manufacturer approval (PMA) and bearing repair services. In September the company announced the year-end closure of its turbine engine overhaul and repair business. No more orders for turbine O&R are being accepted, said Larry Shiembob, director of Timken Aerospace Aftermarket operations in Mesa, Ariz. He added that Timken (Booth 3028) expects to clear its overhaul and repair backlog by the end of October.
Engine condition trend monitoring specialist Jet-Care is making its gas path analysis (GPA) available to operators of Pratt & Whitney Canada’s PT6 turboprop engines. The process detects deterioration and faults in the engine core by analyzing key flight data parameters, including fuel flow, shaft speeds and gas temperatures.
In tandem with the GPA service, Jet-Care also offers an array of laboratory services; analyzing oil, chips, filter debris, fuel and hydraulic fluids. These help to provide a fuller picture of an engine’s condition (see below).
United Turbine Parts (UTP) lays claim to being the world’s leading independent supplier of Pratt & Whitney Canada PW100 and PT6 engines and components. With Latin America having a growing fleet of aircraft powered by these turbine engines, the region is an important growth market for the U.S. company.
The Bauhaus Luftfahrt aerospace think-tank in May unveiled a concept for a “propulsive fuselage” aircraft, opening a new possibility for fuel burn reduction. It is part of a European Union-funded project in cooperation with a number of research centers, as well as MTU Aero Engines and Airbus Group Innovations (OE13). The latter company is also studying a hybrid-power regional airliner with Rolls-Royce (Hall 4 Stand H3). Meanwhile, it is flying a hybrid-lift quadcopter demonstrator for unmanned military and civil missions, the Quadcruiser.
New engines planned by Rolls-Royce (R-R) reflect recent powerplant trends, including steadily increasing propulsive efficiency obtained with larger-diameter fans, higher bypass ratios and smaller engine cores. The engines could power updated contemporary widebody platforms, with R-R civil large engines president Eric Schulz confirming “very live” discussions with Airbus. “If it decides to re-engine the A330 or A380, we will be here to provide support,” he said during a pre-show briefing.
While ATR and Bombardier continue to vacillate over plans to introduce a new 90-seat turboprop, Pratt & Whitney Canada keeps moving forward with a powerplant 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 (probably) an eight-blade propeller.
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.

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.
