Abstract: Because aero-engine theoretic speed can be known not through setting up mechanical gearing, after analyzing the factors of affecting some turbofan engine theoretic speed , we present a RBF network arithmetic that can makes certain of aero-engine theoretic speed. We set up the RBF network model that can make certain of aero-engine theoretic speed by using experimental data as the network’s learning stylebook. Through experiment,
the result shows that the method has the advantage of faster learning rate, higher calculating precision, that it can be used to make certain of aero-engine theoretic speed.
Keywords: RBF NN, aero-engine, theoretic speed, oil-pump adjustor.
