Silent Aircraft concepts are targeted to:

Reduce airframe and propulsion noise by

Improve quality of life near airports

Reduce the operating and societal cost of noise

Enable growth of commercial air transportation

What do we mean by “silent”?

ü

“Silent” means sufficiently quiet that aircraft noise is less than background noise in a well populated area

Heretofore unasked technical question - “what would an aircraft look like that had ...”

ü

Noise as a prime design variable?

ü

A design criterion which is a revolutionary step in noise reduction compared to present configurations?
