Optimal control programs and flight paths of HFV are determined using the method called Pontryagins maximum principle. Optimal control of the angle of attack is expected to provide minimization of the HFV drag force in the supersonic speed range and the recoil from the dense atmosphere in the hypersonic speed range for the terminal flight path angle of over ten degrees.</p>Hypersonic flight vehiclepropulsion jet engineminimum fuel consumptionPontryagin’s maximum principleinitial estimate of conjugate variablesboundary problemoptimal control programrecoilГиперзвуковой летательный аппаратвоздушно-реактивный двигательминимальный расход топливапринцип максимума Понтрягинаначальные приближения сопряжённых переменныхкраевая задачаоптимальная программа управлениярикошет
