Accurate measurement of the thrust coefficient of ramjet nozzles is crucial. Traditional force balances are highly susceptible to external factors such as ambient noise and signal interference. Therefore, the paper proposed directly obtaining the thrust coefficient based on the definition by measuring the velocity, pressure, and density distributions at the nozzle outlet. A non-intrusive reconstruction measurement scheme based on particle image velocimetry (PIV) was proposed for multiple physical fields and the thrust coefficient of a typical single expansion ramp nozzle under over-expansion conditions. The theoretical accuracy of the reconstruction scheme was comprehensively evaluated using synthetic PIV experiments. The results indicate that the thrust coefficient of the nozzle, measured using the reconstructed multi-physical fields from PIV, is about 0.779, with a relative error of only 1.04% compared to the reference value of 0.771. This confirms the feasibility and accuracy of the proposed method.
