This paper describes the status of the study on component analysis for the different Variable TBCC
cycle configurations. The paper investigates different Variable Cycle TBCC configurations and compares
them with an advanced turbojet for the generic configuration of a Mach 4.5 supersonic passenger
airliner.
One VCE engine variant and the turbojet are preliminarily designed and their mass including airintake
and nozzle is estimated. The air-intake has been preliminarily sized and pressure recovery and
mass flow in design and off-design conditions is estimated. The intake's dimension and airflow data
have been subsequently delivered for further analyses. Engine weight analysis is also conducted both
for existing engines and proposed LAPCAT turbo engines
