Jet Thrust Performance Guide

Engine Type	Typical Thrust (kN)	Typical TSFC (kg/(N·s))
Turbojet	20 – 100	2.0e-5 – 3.0e-5
Turbofan	50 – 500	1.0e-5 – 2.0e-5
Ramjet	50 – 200	3.0e-5 – 5.0e-5
Electric Jet	1 – 50	N/A

📌 Note: Results are based on momentum theory and ideal gas dynamics. Actual performance depends on combustion efficiency, compressor performance, nozzle design, and atmospheric conditions. For electric jets, efficiency depends on fan design and motor performance. TSFC (Thrust Specific Fuel Consumption) measures fuel efficiency.
