Preliminary Evaluation of a Turbine/Rotary Combustion Compound Engine for a Subsonic Transport [PDF]

open access: yes
The fuel consumption of a modern compound engine with that of an advanced high pressure ratio turbofan was compared. The compound engine was derived from a turbofan engine by replacing the combustor with a rotary combustion (RC) engine. A number of boost
