Researchers To Release Design For Silent Jet

Tue Nov 07, 2006 9:10 am

Saw this article today. I have seen posts in the past about something like this but it looks we will finally see exactly what it will look like.

CAMBRIDGE, Mass., Nov 5 (Reuters) - 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 the Massachusetts Institute of Technology and Cambridge University spent three years working on the wide, streamlined jet, which they plan to unveil in London on Monday.

Leaders of a long-range research venture called the "Silent Aircraft Initiative" were scheduled Monday to release a conceptual design for a plane they say could cut through the air with practically no sound bothering those below, thanks to its unique shape and design features to limit engine noise.

I double posted so I will repost my notes here.

Heard this on the BBC (2006/11/06) podcast.

An aircraft designed by Cambridge and MIT that runs on conventional fuel but is as noisy as a washing machine.

The Silent Aircraft Initiative

Quote:
The Cambridge-MIT Institute's 'Silent' Aircraft Initiative was launched in November 2003 with a bold aim: to discover ways to reduce aircraft noise dramatically, to the point where it would be virtually unnoticeable to people outside the airport perimeter.

I saw this article on CNBC. They played a part on it. They weren't quite logical though since they showed off how much noise flaps make and how much noise can be eliminated by not having flaps. Somehow they forgot about the engines when they described the plane. But I think that is just how CNBC showed it. The engines are on top and that plane looks a lot like the B2, which if you've seen it in person, you know that it is completely silent until after it has pased you.
If you have never designed an airplane part before, let the real designers do the work!
