摘　　要：针对水平起降重复使用运载器爬升轨迹,提出了一种单纯形-伪谱循环优化算法,内层算法基于hp自适应Radau伪谱法,外层算法基于单纯形算法,通过对滑跑段控制参数优化,实现自适应爬升段初值生成,并以某水平起降重复使用运载器为例,完成了运载器滑跑起飞并爬升至交班点的轨迹优化设计仿真,验证了所提方法的可行性与有效性。在此基础上,研究了发动机推力、飞行轨迹敏感参数对吸气模态飞行剖面和剩余质量的影响,同时提出了一种吸气模态动力补偿的设计方法,相比常规的设计方式,进一步减少了燃料消耗,提升了运载能力。Regarding the ascent trajectory of horizontal take-off and landing reusable launch vehicles,a simplex-pseudospectral loop optimization algorithm is proposed.By optimizing the control parameters of the horizontal run section,the initial value of the ascent section is adaptively generated,and taking a cer⁃tain horizontal take-off and landing reusable launch vehicle as an example,the trajectory optimization design simulation of the launch vehicle from taking off to climbing to the handover point is completed by using the simplex-pseudospectral double-loop optimization algorithm,which verifies the feasibility and effectiveness of the proposed method.On this basis,the influences of engine thrust and sensitive param⁃eters of the flight trajectory on air-breathing mode flight profile and remaining mass are studied.At the same time,a design method of air-breathing mode power compensation is proposed.By comparing with the conventional design method,fuel consumption is further reduced and the carrying capacity of the reusable launch vehicle is improved.
