Abstract

Heat input reduction by optimal trajectory control is considered for the range cruise of a hypersonic carrier vehicle propelled by a turbo/ram jet combination. A mathematical model is developed for describing the unsteady heat transfer through a thermal protection wall system. This model is coupled to the equations of motion of the vehicle. An efficient optimization technique is applied for constructing a solution of the range cruise problem. The results show that a significant heat input reduction can be achieved while there is only a small increase in fuel consumption.
