Status and trends in development of hypersonic integration configuration with dorsal intake

The novel dorsal intake hypersonic configuration has become a research hotspot in the aerospace industry due to its superior aerodynamic and inlet performance at small angles of attack. Advanced design theories and performance evaluation methods are crucial technologies to support the development of integrated vehicles with dorsal intake. At the same time, the specific configuration is also the bottleneck that restricts its development. This paper reviews the development status and trends of hypersonic integration configuration with dorsal intake. First, the development status of the hypersonic integration configuration with dorsal intake is exhibited. Second, the flow characteristics and advantages of the dorsal intake configurations are discussed. Thirdly, this paper introduces the design methods of the dorsal intake configurations in detail. Immediately, combined with the configuration characteristics of the dorsal intake, this paper analyzes the shortcomings restricting the development of dorsal intake. Finally, combined with the development demand and technology development trends of hypersonic vehicles, the future development direction of the dorsal intake configuration is summarized.
