Derivation of thrust equation
WebMar 7, 2024 · Thrust is caused by a change in momentum, or/and an increase in static pressure, acting over an area. So, for a gas turbine, Net thrust (FN) = M x (Ve - Va) / g + Ae x (Pse - Pamb). Va is the aircraft velocity, Ve is the exhaust velocity. The physics is the same for a prop, but when the flow is subsonic, Pse = Pamb.
