With the massive upward swing of the technology J-curve in our current age, it is increasingly difficult to determine what innovations are quaint little doodads, and which represent a revolutionary shift. Only the future will tell, but I believe the Silent Aircraft Initiative (SAI) is birthing one of those revolutions: the SAX-40 blended-wing aircraft (quick design primer).
Since its beginning, most aircraft have followed the “winged tube” design. It’ll get you from A to B, but has several design flaws that hinder fuel efficiency and make for a lot of noise. The SAX-40 design (developed by a team of MIT and Cambridge engineers) reduces fuel usage by up to 35% and is purported to be 3000 times quieter than today’s airliners.
Keep your eye on this project. I think this is the future of air travel.
