SUMMARY
The discussion centers on the principles of velocity and motion in jet engines, specifically the role of air compression and combustion. It is established that compressing air at high speeds through the gas turbine inlet and subsequently colliding with turbine blades generates forward motion due to differences in velocity. The combustion process heats the gas, increasing its volume and contributing to thrust. A hypothetical scenario illustrates that if one cubic meter of air enters the engine per second while 100 cubic meters exit, this indicates a significant increase in velocity, crucial for understanding jet propulsion.
