In order to calculate the instantaneous thrust of the engine quickly and accurately, a thrust calculation method based on Radial Basis Function (RBF) is proposed. The results of numerical examples show that the interpolation results using radial basis method have high precision and mature algorithm, and can be easily implemented by computer programming. So the instantaneous thrust interpolation problem can be solved quickly. The method can be widely used in aircraft design, especially in performance calculation and parameter optimization.
