The first 100-percent civil biofuel flight, conducted on October 29 in a Falcon 20, showed that the fuel is cleaner and just as efficient as conventional jet-A, according to results released by the National Research Council (NRC) of Canada. Information collected in flight and analyzed by the NRC revealed a 50-percent reduction in aerosol emissions.
The ever-increasing use of composites in aerospace has given rise to technological advances not only in aerodynamics but in so-called green disciplines. Engineers have studied different processes for decades, and recycled composites from Boeing 787s have already found their way onto recreational products such as kayak paddles.
Reaction to the collapse of negotiations between Hawker Beechcraft and Superior Aviation Beijing seems to be less that of surprise and more about the inevitability of the dead end the two companies reached.
L.I.F.E., a new Portuguese multi-discipline consortium, has been formed to explore “the design, development and industrialization of functional technical solutions for aircraft interiors,” and will work in collaboration with Almadesign of Porto Salvo, Portugal, and Brazilian aircraft manufacturer Embraer.
The FAA has warned operators with carbon brakes about problems with environmentally friendly organic salt runway de-icer fluids. Aircraft manufacturers have notified the FAA that spray between the wheels causes the de-icer fluid to coat carbon brake heat-sink (pressure) plates.
Complex materials, made of carbon fiber composites and a metal, are tricky to characterize. “We already know that titanium is a better match than aluminum with carbon fiber,” research coordinator Benoît Sagot-Duvauroux said. But now researchers are endeavoring to put numbers on corrosion and dilatation issues, for example. Simulation of real-world operating conditions is the key to success in this work.
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?
