A difficulty in studying natural evolution is that it occurs on a time-scale much greater than our lifetime. However,in a recent study published in the Journal of Applied PhysicsProf. Bejan and co-workers show that the shorter technological evolution of airplanes allows us to witness the phenom...
The inclusion of turbulence effects is found to be essential to capturing the correct near-field development. The CFD results are shown to be in very good agreement with experimental wake-survey results out to ten spans. Results show that wing loadings typical of commercial airplanes in a ...

“The 1959 Pan Am 707 was one of the last of the airplanes that we delivered with one class of service before the introduction of tourist class,” said Wilcynski. ”What’s interesting is that even in the late ‘50s you can see that these seats didn’t have tray tables in the back...
With more than 300 different aircraft to fly — including RC airplanes, RC helicopters, drones, and more — at over 75 different flying sites, there are many combinations to keep the fun going. Plus, you have the ability to edit and add RC aircraft and flying sites, so there’s an ...

As a comparison – imagine a scenario where we knew that oil fuel available from the year 2030 would be “contaminated” and may explode, causing significant damage. Hence, everything from scooters, grassmowers, personal automobiles, ambulances, police cars, trucks, and motorboats to airplanes an...
W e do not intend to do so any more than we would choose to interrupt this paper by arguing in abstract terms whether it is to airplanes or only to pilots that flying should be attributed. Our purpose here is to propose a scheme based on biological evolution for achieving certain ...
Including air transport industry in EU-ETS along with the increasing demand of air travel have motivated research and investment into sustainable fuel alternatives, more efficient airplanes and green technologies, and improvements in air traffic management (Gegg, 2014, Krammer et al., 2013, ...
Since the advent of aerial navigation in the United States and through the formation of the FAA in 1958 until the present day, an under-lying principle of airspace management has always been for controllers to issue clearances and optimize traffic flow on a "first come — first served" basis...
