The Turbofan Engine

Fundamentals of Propulsion, 2021
In the last chapter, the turbojet engine was discussed in detail. Historically, commercial aviation began toward the end of World War II with propeller-driven planes. It soon became apparent that the flight speeds of the propeller planes were limited to low subsonic values. The use of the gas turbine engine in combination with a propulsion nozzle, i.e.,

Digital Twins-Based Online Monitoring of TFE-731 Turbofan Engine Using Fast Orthogonal Search

IEEE Systems Journal, 2022
Due to the complicated structure of the aircraft engine, it is hard to observe the damage and determine its status with the traditional diagnosis method, which sets a fixed threshold for some specific parameters.

Hex Turbofan Engine

Applied Mechanics and Materials, 2012
Looking into the future of aviation for commercial aircrafts there are various viable options for engine and associated propulsion technologies. The team had to eliminate some of the possible solutions. Superconducting electric motors were alleviated considering weight factors and lack of technology readiness to fly long range commercial jets.
