The invention relates to an aerodynamic layout design method and appearance of a large swept wing double-cone structure standard model, and belongs to the technical field of aerodynamic layout design of aircrafts. Firstly, an aircraft head area contour line is designed, then an aircraft fuselage double-cone structure is designed, and an aircraft sweepback wing contour line is designed. And finally, obtaining a wing structure of a symmetrical part through left-right symmetry to complete the aircraft section design. The appearance generated by adopting the design method has the characteristics of large sweepback wing body combination configuration modeling and the characteristics of a current typical hypersonic velocity wing body combination aircraft. The research requirement of a transition mechanism can be met, and meanwhile, the up-down and left-right symmetrical design meets the data comparison verification requirement in the flight test process. Due to the connection design of the double-cone structure serving as the fuselage and the wings, on one hand, the aircraft is simple in structure; the circular section feature of the aircraft fuselage ensures that the aircraft has a good filling space, and filling of measuring instruments in a flight test is facilitated.
本发明涉及一种大后掠翼双锥结构标模气动布局设计方法及外形,属于飞行器气动布局设计技术领域。首先设计飞行器头部区域轮廓线,然后设计飞行器机身双锥结构,设计飞行器后掠翼轮廓线。最后通过左右对称得到对称部分的机翼结构,完成飞行器截面设计。采用本发明设计方法生成的外形,具备大后掠翼身组合体构型造型特征,以及当前典型的高超声速翼身组合体飞行器特征。能够满足转捩机制的研究要求,同时上下左右的对称设计满足飞行试验过程中数据的对比验证需求。作为机身的双锥结构和机翼的相接设计,使飞行器一方面构型比较简洁。飞行器机身的圆形截面特征保证了飞行器具有较好的装填空间,有利于飞行试验中测量仪器的装填。
