Optimal periodic control is an effective technique to reduce aerodynamic heating and fuel consumption of hypersonic cruise vehicles. Herein, this optimal control problem has been solved by nonlinear programming and passed the posteriori check of optimality. The results indicate that the lift coefficient and velocity in dynamical model could be recognized as constants. Accordingly, the original 3D system consists of velocity, flight path angle, and altitude, which could be decoupled into a 2D subsystem and a 1D one. The 2D subsystem could describe the correlation between the flight path angle and altitude. And the period length is mainly dependent on the maximum altitude difference. The 1D subsystem has been proved to be feasible to describe the variation of kinetic energy or velocity. On basis of the subsystems, the heating and fuel performances of periodic cruise have been studied. The heating performance is mainly dependent on the maximum altitude difference, and the fuel consumption is mainly dependent on the drag coefficient. The features concluded in this paper can support rapid trajectory planning or suboptimal feedback design of hypersonic cruise vehicles.

Leading edge is a primary element that forms waverider configurations. To design waveriders from given leading edges directly and accurately, a new method named the “leading-edge cone method” has been proposed. The leading-edge cone is a conical surface whose tip lies on the leading edge. The shock surface related to the leading edge is the enveloping surface of multiple leading-edge cones. The geometric relationship between leading-edge cones and the shock surface is a particular case of the Apollonius problem in mathematics. Six conditions of leading-edge cones have been discussed, and mathematical expressions of the shock surface are presented. The leading-edge cone method is then established based on these mathematical expressions. Three test cases and three application cases are employed to validate the effectiveness and accuracy of the leading-edge cone method. Results show that all the cases designed by the leading-edge cone method meet the design requirements, and shocks derived from given leading edges coincide well with the shocks generated in numerical simulations.
