- Specific thrust is the thrust per unit air mass flowrate of a jet engine1. It can be calculated by dividing the thrust created by the engine by the mass flow rate of the air2. The formula for calculating specific thrust is Fs = F / m = (1 + mf) * Ve - V0, where Fs is the specific thrust, F is the net thrust, m is the air flow rate through the engine, mf is the fuel-air ratio, Ve is the nozzle exit velocity, and V0 is the free stream velocity3. The net thrust can be calculated using the formula Thrust F = mdot e * Ve - mdot 0 * V0 + (pe - p0) * Ae4.Learn more:✕This summary was generated using AI based on multiple online sources.
