MIT team designs plane that uses 70% less fuel Answered
Planes use a massive amount of fuel to move passengers and cargo around the world. A new design from an MIT team could cut this fuel usage by 70%. This is great news and would make flights cheaper and pump out a lot less carbon. The bad news is that air traffic is expected to double in the next 30 years and the earliest these designs would be in the air is 2035.
MIT designed their D-series as a 180 passenger aircraft meant to replace the domestic 737 market. Conventional airplanes utilize a single fuselage design, while the D-series uses two partial tubular shapes placed beside each other — which accounts for the bubble nickname. The plane utilizes a host of technological advances to decrease its fuel consumption. It has thinner longer wings and a smaller tail and engine placement at the rear of the plane instead of on the wings. All of these features account for part of the reduction in fuel usage.
