'Silent jet' could ease airport noise


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.

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.

Instead of the tube-and-wing model common today, the Silent Jet is a flying wing, evoking current "stealth" military aircraft. It lacks the central vertical stabilizer common at the tail of current passenger jets, instead using a pair of stabilisers at the wingtips.

The design allows the plane to remain in the air at slower speeds, which would allow it to cruise in for a landing more quietly. The plane does not use wing flaps, which are common on today's passenger jets and create much of the landing noise.
