Which forward force is produced by the propulsion system?

Explanation:
The forward force produced by the propulsion system is thrust. It’s the push that moves the airplane forward along its longer axis, generated by the engines or propulsors when they accelerate air or exhaust rearward. Lift acts upward to balance weight, weight is the gravitational force downward, and drag is the resistance that acts opposite to the direction of motion. In steady, level flight, thrust must overcome drag to maintain speed, while lift supports the weight. So the propulsion system specifically creates the forward thrust.
