"Although Bell won't unveil an all-new helicopter model, Redenbaugh says he will announce a plan for developing new and improved models at the Helicopter Association International Heli-Expo trade show Sunday.
He declined to discuss specifics, but sources within Bell say engineers are working on three projects that could lead to improved aircraft within a couple of years.
A tail-rotor shroud, known as a fenestron, is being designed and will be tested on a Bell 407, the company's bestselling helicopter. Used for years by other manufacturers, the shroud produces a quieter aircraft and reduces the risk of someone being maimed by the tail rotor"
