Phillip Ansell, assistant professor in the Department of Aerospace Engineering in the College of Engineering at the University of Illinois explains the benefits and downsides of fossil fuels. “Jet fuel and aviation gasoline are easy to store on an airplane. They are compact and lightweight when compared to the amount of energy they provide. Unfortunately, the actual combustion process is very inefficient. We’re harnessing only a small fraction of that energy but we currently don’t have electrical storage systems that can compete with that.” Ansell and colleagues are striving to use simulations to increase the range of hybrid aircraft. Batteries provide their own set of problems. He explains that adding more batteries to go farther may have a certain logic, for example, but increases weight – a big detriment. “That’s one of the big barriers we run into when designing battery-powered electrified aircraft. The current technology has very significant range disadvantages. But strong fuel-burn advantages.” eVTOL News recently noted that over …
Communicating Between Ducted Fans and the Wing
Aircraft quite often seem to get designed as an assembly of separate components, wings an entity unto themselves, engines or motors something attached to the fuselage or wings, and not always seen as a set of matched components until final assembly. Quite often, different components are compromised from their optimal shape or structure because of the need to integrate them with other parts of the craft. One group of researchers is finding ways to even cause components to begin communicating among themselves. Some parts, such as engines or motors, are hung on the wing or fuselage as replacements for earlier design variants. The new powerplants may provide additional power, but they may also interfere with the overall performance and handling of the airplane. University of Illinois researchers led by Dr. Phillip Ansell, assistant professor in the Department of Aerospace Engineering in the College of Engineering has explored this subset of aeronautics and come to the conclusion that wings and propulsion …
