The effect of Linear Damping is proportional to the mass of the object, so if you have two objects of 100 and 1000kg then linear damping of 50, for example, will slow down lighter object 10 times faster as object is 10 times lighter. Just be aware of that.
I’ve read about traction force and I’m not sure it would be useful to you, assuming we are talking about the same meaning of traction force, it’s a bit weird that you use it in a context of the jet engine. Normally it’s used on something like train locomotives or trucks to compare them to each other or to know upfront if a specific train can pull some specific load of wagons/carts. For jet/rocket engines, the terms that I know are Specific Impulse, Thrust and their variations. You could describe “traction force” for an aircraft if you replace rolling friction with the air drag, but there should be a different term for this in aerodynamics already.
