Solid-Fuel Regression Rate Modeling for Hybrid Rockets
Journal of Propulsion and Power, 2013 The regression rate of the solid fuel is a primary parameter in the performance analysis for a hybrid rocket. Many studies in the past few years have theoretically claimed, or experimentally shown, a dependence of the regression rate on the chamber total pressure. Such behavior is generally traced back to the presence of oxygen below the flame zone and

Modelling and Neuro-Adaptive Robust Control Algorithms for Solid Fuel Rockets
Journal of Aerospace Technology and ManagementABSTRACT This study presents the development of a methodology for designing neuro-adaptive robust controllers based on a reference model associated with an artificial neural network of radial basis functions (ANN-RBF) for solid fuel suborbital rockets. The modelling and neuro-adaptive robust control algorithms for these rockets are presented. Initially,
