In a bid to simultaneously reduce both fuel consumption and all pollutant emissions–goals that are often at odds–French aerospace research center Onera and engine manufacturer Snecma are working on the next generation of low-NOx combustors
The University of Dayton Research Institute (UDRI) was awarded a nearly $50 million six-year research grant from the Air Force to develop advanced fuels and combustion technologies. A key area in the UDRI program will be the development, validation and field testing of synthetic fuels, including biofuels from varied feed stocks.
The University of Dayton Research Institute (UDRI) has been awarded a nearly $50 million six-year research grant from the Air Force to develop advanced fuels and combustion technologies. The award follows last year’s $10 million contract with the Air Force Research Laboratory to design and operate the new Assured Aerospace Fuels Research Laboratory at nearby Wright-Patterson AFB.
Goodrich Corp. has signed a research agreement with Rolls-Royce to develop the new fuel nozzles for “lean burn” combustion technology systems for gas turbine engines, Goodrich announced today. Rolls-Royce has also chosen Goodrich to supply the fuel nozzles for the new Rolls-Royce Trent XWB engine for the Airbus A350XWB widebody.
Eurocopter is here exhibiting its “Bluecopter” diesel engine concept on the static display. The so-called “high-compression engine” is supposed to bring greener performance to light helicopters currently powered by a single turboshaft. Targeted are a 40-percent cut in CO2 emissions and a 53-percent reduction in NOx emissions.
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.
Spectrum Aeronautical (Booth No. 1947) has quantified the CO2 that will be generated by its Freedom S-40 and Independence S-33 business jets and compared those to competing jets to see how the Spectrum jets stack up emissions-wise. On a 600-nm flight, the midsize S-40 generates slightly less than 1,500 kilograms of CO2, according to Spectrum, while comparable jets should generate more than 2,000 kilograms to nearly 4,000 kilograms.
Pratt & Whitney Canada is showcasing its latest green engine technologies at Paris centered on the 10,000-pound-thrust-class PW-10X engine it is developing for business jets and regional airliners.
Fire is the sharpest two-edged sword in man’s bag of tools. When under control it was a formidable tool that warmed, comforted, cooked food and kept wild beasts at bay for prehistoric man. Today, it fulfills those and many other needs, yet out of control it is man’s worst nightmare. What greater fear can a pilot have than being at altitude with a fire in the cabin?
Rolls-Royce is now exploring future engine technologies that, although challenging, are key to the ambitious Advisory Council for Aerospace Research in Europe (ACARE) goals for 2020 in terms of nitrous oxides (NOx) and carbon dioxide (CO2) emission cutting and noise reduction. These technologies range from heat exchangers to shape memory alloys and magnetic bearings.
