DLR scramjet engine is one of the well-known strut base parallel fuel injection engine, with significant thrust force due to low pressure loss but with slight decrease in combustion performance. The performance parameters such as combustion efficiency and thrust force are generally affected by design variables such as strut angle and divergent angle of the engine. In this context, ANN models were developed to foretell the performance parameters of DLR scramjet engine for varying strut angle and divergent angle. The results predicted by the developed ANN models are comparable to the computational results. In addition, it is seen that the statistical indicators like R2, RMSE and MAPE are in the range of 0.997–0.999, 0.038–0.016 and 3.38–1.26 for prediction of combustion efficiency and thrust force. Therefore, it can be finally concluded that the developed ANN models are competent to predict the performance parameters such as combustion efficiency and thrust force of the DLR scramjet engine.
