Embodiment
[0025] A modular design method for a hypersonic cruise aircraft, the combined layout aircraft adopts a combined design of a waverider precursor, a waverider wing and a center body, and is longitudinally divided into two sections, the waverider precursor is the first section, the wing and the center body. is the second paragraph. The front body adopts a definite waverider trailing edge curve design, which is convenient for matching with the engine in the future. The trailing edge line of the lower surface adopts a quartic curve line, but it is not limited to this curve type, y(z)=az 4 +bz 2 -R 0 . The waverider wing adopts a certain leading edge curve, and at the same time meets the requirements of smooth transition with the waverider precursor and the sweep angle of the wing. For the preliminary design of the center body, the trailing edge streamline of the lower surface of the waverider precursor is directly traced to the bottom of the wing to form the lower surface of the...

The invention discloses a modular design method for a hypersonic cruise aircraft, and relates to the technical field of aircraft design, and the technical scheme is characterized in that based on a plurality of reference conical flow fields, the layout configuration of the aircraft is subjected to segmented design in the longitudinal direction, and the aircraft is divided into a front body, a center body and wings according to functions; and the front body, the center body and the wings are independently designed according to requirements, so that different flight requirements can be met. The multi-component design of the hypersonic aircraft is realized on the basis of a plurality of reference conical flow fields, so that the aircraft can have the performance of a traditional waverider, the design parameters of different components can be changed, the design parameters of the aircraft are diversified and convenient to adjust, the block design processing of the hypersonic aircraft can be realized, and the design cost is reduced. And the method has better engineering application value.
