Waverider is expected to break the lift-to-drag ratio constraint in the hypersonic flight condition and it is commonly been studied as the forebody of the cruise vehicle. In this paper, we developed an approach to make waverider as the airframe for the air-breathing cruise vehicle. The fuselage that designed based on the cone-derived waverider theory with a unique upper boundary curve generates the same conical shock wave as that generated by the conical nose of the vehicle. Therefore, the vehicle is expected to have a full-body wave-ride performance and suitable for cruising in the hypersonic condition. Also, a gap between the conical nose and the fuselage is designed to be the inlet of the air-breathing engine. In comparison with the traditional cone-derived waverider, this kind of configuration has additional volume so that it can afford enough space for installing the engine system in the airframe. The performance of this kind of configuration is validated by the numerical method in the design Mach number. With the engineering estimation approach used to calculate the aerodynamic performance of the vehicle in hypersonic conditions, we studied the influence of design parameters on the aerodynamic performance. Results show that the increase of the design Mach number does negative impact on the lift-to-drag ratio but positive impact on the volumetric efficiency while the increase of the design direction angle has an opposite influence. However, in comparison with the response of the lift-to-drag ratio, the volumetric efficiency is less affected by the dihedral angle, which means that the dihedral angle can control the aerodynamic performance effectively within a limited volumetric efficiency range.

Waverider有望打破高超音速飞行条件下的升阻比约束，通常作为巡航飞行器的前身进行研究。在本文中，我们开发了一种方法，将乘波器作为吸气式巡航车的机身。基于锥形推波器理论设计的机身具有独特的上边界曲线，产生的锥形冲击波与飞行器的锥形机头产生的锥形冲击波相同。因此，该车辆有望具有全身波浪乘驾性能，适合在高超声速条件下巡航。此外，锥形机头和机身之间的间隙设计为吸气式发动机的进气口。与传统的锥体衍生乘波器相比，这种配置具有额外的体积，因此可以提供足够的空间在机身中安装发动机系统。这种配置的性能通过设计马赫数中的数值方法进行验证。采用工程估算方法计算高超声速条件下飞行器的气动性能，研究了设计参数对气动性能的影响。结果表明，设计马赫数的增加对升阻比有负面影响，但对容积效率有正面影响，而设计方向角的增加则相反。然而，与升阻比的响应相比，容积效率受二面角的影响较小，
