CAMBRIDGE: A radically redesigned passenger jet could alleviate a major complaint of people who live near major airports the deafening sound of planes taking off and landing.
A team of 40 researchers from Cambridge University and the Massachusetts Institute of Technology spent three years working on the wide, streamlined jet, which they plan to unveil in London on Monday. The "silent jet," which from outside an airport would sound about as noisy as a washing machine or other household appliance, would carry 215 passengers and could be in the air by 2030.
"Noise really is one of the major barriers to airport expansion and the expansion of flights," said Edward Greitzer, an MIT professor who helped run the project. "It gets a lot of complaints." The breakthrough could bring a welcome change to aviation, industry experts said.
"People are still willing to pay more for the convenience of a closer-in airport," said Richard Aboulafia, vice president at Teal Group, an aerospace consulting firm in Fairfax, Virginia. "There is an economic value to being able to keep your air transport close in town, which means you've got to be quiet."
Reducing noise in recent years has been a focus of makers of planes, such as Boeing Co and Airbus, and jet engines, including General Electric Co, United Technologies Corp and Rolls-Royce Plc.
