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.

Titanium-aluminide low-pressure turbine blades and proposed cooling arrangements on Rolls-Royce’s proposed future UltraFan engine may owe much to the RB3025 powerplant unsuccessfully offered to power the Boeing 777X. For example, the RB3025 featured a “vortex amplifier” to simplify turbine-blade cooling with HPC air.

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.

Pratt’s envisioned NGRT engine would feature an all-new compressor, a miniaturized version of P&W’s Talon combustor and possibly an eight-blade propeller.

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.

Big Ass Fans has found a niche in the aviation market, where its fans are used to circulate and cool air in hangars. Some of the models can be equipped with security cameras, fire-suppression equipment and LED lights. The company’s booth at the show is being cooled by an 18-foot ceiling fan.

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.

A Dallas Airmotive field service tech inspects a PW500 engine.

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.
