Benefits of technology

This new design allows for better integration of both the airfoil's main structure (body) and its interior components like turnings inside). It also improves lifting efficiency while maintaining good aerodynamic properties at lower speeds. Additionally, this design helps reduce fuel consumption without compromising flight safety or reducing power output during take off phases due to increased turbulence caused by the rotating blades.

Problems solved by technology

This patented technical solution describes how combining aerodynamic structures (such as wings) together helps improve flying capabilities without sacrificing weight or fuel efficiency. Current designs involve integrating separate parts into one component while still maintaining their strength.

Abstract

The invention discloses a hypersonic-velocity inner-and-outer flow integrated design method based on a typical internal-rotation air inlet channel. The method comprises the following steps that (1), according to design requirements, a shock wave curve and a virtual shock wave curve in a designed section are designed; (2), a series of basic flow fields are reversely worked out by using the relationbetween a discrete shock wave curve and a curvature center, wherein the basic flow field comprises an inner shrinkage basic flow field and an outer compression basic flow field; (3), the projection of the outlet shape of a three-dimensional internal-rotation air inlet channel on the design section is designed; (4), the projection of a leading edge capturing type line of an aircraft body on the design section is designed, downstream flow line tracking is carried out in the outer compression basic flow field mentioned in the step (2) multiplied wave body compression molded surface, and naturaltransition of two parts of inner-and-outer flow can be realized though a two-dimensional plane compression section; and (5), the integrated design is completed through constructing other parts of thehypersonic-velocity multiplied wave aircraft. The inner-and-outer flow integrated device has the advantages that the performance advantages of the multiplied wave aircraft body and the internal-rotation air inlet channel are brought into full play.
