Application of TURBOSUPERCHARGERS to POSTWAR COMMERCIAL AIRCRAFT

THIS paper presents a brief history of past experience at Boeing with turbosupercharged airplanes. Installation problems are discussed by the author who also offers suggestions for future design.

A basic airplane and engine are chosen and several types of supercharging analyzed by Mr. Disch. A method of turbo selection is also briefly presented by him.

Assuming that flight at 25,000 ft is desired, a comparison of range and payload is shown, depicting the benefits of employing a cruising type of turbosupercharger for increased fuel economy and range.

In conclusion, the author summarizes the overall benefits with this type of installation.
