    en.wikipedia.org/wiki/Bell_nozzle

    The bell-shaped or contour nozzle is probably the most commonly used shaped rocket engine nozzle. It has a high angle expansion section (20 to 50 degrees) right behind the nozzle throat; this is followed by a gradual reversal of nozzle contour slope so that at the nozzle exit the divergence angle is small, usually less than a 10 degree half angle.

    Wendell Moore developed the Bell rocket belt, utilizing peroxide monopropellant rocket engines. While the rocket belt failed to be commercially developed, the rocket technology proved invaluable in future Bell programs. Bell's crowning achievement in the realm of rocketry was the Agena rocket engine. The Agena was a 12,000 lbf bi-propellant ...
