This Garrett engine is tiny compared to ts1400. Also it is a high bypass turbofan. (5:1). ( As an example; Ukranian engine AI222 is low bypass with AB has a bypass ratio of 1.19:1)
20inches diameter contains the fan which has to be big to create the high bypass value and thrust needed As most of the thrust is generated by the fan. Not the jet turbine, which will be very small!
Below is the excerpt taken from defenceturkey magazine:
“Thus, the core technology of the TS1400 Engine shall also form the basis for the indigenous turbofan engine (in 8,500lbf to 9,500lbf thrust class) needed for the HURJET New Generation Advanced Jet Trainer (AJT) & the Light Attack Aircraft Development Project, and it will be possible to develop the national aircraft engine when needed, upon any necessary technological additions to the capabilities gained under the TEDP.”
Original Power System TS1400 Turboshaft Engine Developed by TEI’s Seasoned Team of Experts for the T625 Helicopter
As a close follower of development and innovations in the field of aviation engines TUSAS Engine Industries Inc. (TEI) has accomplished important milestones in the initiatives toward developing the indigenous and national TS1400 Turboshaft Engine under the Turboshaft Engine Development Project...
