本文的重点是在“紧急商务旅行”和“快速货物运输”细分市场和/或亚轨道视角的框架下，设计一种6-8座冲压式超音速飞行器，目标行程为6000公里。为了保证在适当选择的点对点飞行路径上具有非常低的运行载荷条件，开发了一种具有相对高升阻比和低机翼载荷系数的飞行器结构。采用气动效率高的圆形双后掠三角翼，前缘相对锋利。设想一个涡轮冲压喷气推进系统与一个液体火箭助推器相结合，以维持太空旅游的“多跳”飞行，同样的飞行器将能够保证在与太空旅游飞行相关的上拉机动期间为乘客提供相对平稳的环境条件。本文主要关注洲际点对点和太空旅游飞行的市场前景，并证明在20年的投资情景中，在非常低的票价下，盈亏平衡点可能在相对较短的时间内出现。
The paper focuses on the design of a 6-8 seat ramjet-based hypersonic vehicle for a target trip of 6000 km in the frame of the “urgent business travel” and “fast cargo transportation” market segments and/or for suborbital perspectives. A vehicle configuration with relatively high lift-over-drag ratio and low wing loading factor has been developed in order to guarantee very low operational load conditions along properly chosen point-to-point flight paths. An aerodynamically efficient rounded double swept delta wing with relatively sharp leading edges is implemented. A turbo-ramjet propulsion system is envisaged coupled with a liquid rocket booster to sustain space tourism “multi-jump” flight, The same vehicle will be able to guarantee relatively smooth environmental conditions for passengers during the pullup maneuvers associated with space tourism flight. The paper mostly focuses on the market perspectives for both intercontinental point-to-point and space tourism flights, and demonstrates that the break-even point may occur in a relatively short period over a twenty year investment scenario, with very low ticket prices.
