Design Description of a Four-Place Business Jet Using Two WR-19 Engines

This paper describes the design of an advanced, four-place business jet airplane around two Williams-Research WR-19 engines. In addition to the general layout, the performance, weight and balance characteristics of the airplane are described and illustrated by graphical examples. A detailed comparison in terms of fuel-used is made with the Learjet M35, the Cessna Citation I, the Foxjet and several other general aviation twins. It is shown that the airplane described offers substantial advantages in terms of fuel economy over all these airplanes.
