I am trying to calculate the takeoff ground roll distance. Some parameters are required, such as roll friction, vehicle weight, CL, CD, thrust, lift-off speed Vlo, etc. The major challenge I am experiencing is the thrust of propeller at various aircraft speed. Ideally I would like to have some formula that will take propeller diameter and pitch, engine power and rpm, free stream speed (vehicle speed + wind) and give out a thrust in Newton or lb. If you have other methods I would also like to learn about them.
