【摘要】：随着航天事业的不断发展,各国在航天领域的投入也呈增长趋势,降低航天成本已成为大规模航天活动的关键所在。上世纪80年代,美国立志于研究可重复使用的飞行器—航天飞机,但由于高额的使用维护费用,低效的使用率以及安全的不稳定性,航天飞机在2012年被全部退役。然而人们对于这种空天一体化,可重复使用的飞行器的探索并未终止。空天飞机凭借着其超前的技术理念和设计理念,解决了航天飞机成本、效率、安全性等难题,成为未来航天发展的新方向。本文首先阐述了空天飞机的发展概况,分析了早期空天飞机的理念和现阶段空天飞机的发展现状。通过研究比对得出空天飞机的理念优势,并分析其应用前景。而后,分析空天飞机的技术理念,即动力技术,防热技术,密闭技术等,验证空天飞机技术的可行性。通过典型案例分析,推导空天飞机的造型设计理念,即它的入轨模式,起飞方式和气动布局。并逐一进行比较分析,得出其不同种模式下的优势与缺点。在此基础上,将空天飞机的设计理念应用于概念飞行器的设计之中,通过草图绘制,确定概念飞行器的基本外形,以此为基础进行3D建模,通过Flame验证其造型的可行性。之后完成概念飞行器的配色渲染,细节纹理展示,以及最终的环境展示。
[Abstract]:With the continuous development of space industry, the investment of various countries in the field of space is also increasing, and reducing the cost of space has become the key to large-scale space activities. In the 1980s, the United States was determined to study reusable aircraft, the space shuttle, but was completely decommissioned in 2012 because of high maintenance costs, inefficient usage and safety instability. However, the exploration of this kind of space-space integration, reusable aircraft has not ended. With its advanced technical concept and design concept, the space shuttle has solved the difficult problems of space shuttle cost, efficiency and safety, and has become a new direction of space development in the future. In this paper, the general situation of the development of aerial aircraft is described, and the concept of early aerial aircraft and the present situation of the development of aerial aircraft are analyzed. Through research and comparison, the concept advantages of aerial aircraft are obtained, and its application prospect is analyzed. Then, the technical concept of air-to-air aircraft, that is, power technology, heat protection technology, airtight technology and so on, is analyzed to verify the feasibility of air-to-air aircraft technology. Through the analysis of typical cases, the modeling design concept of aerial aircraft is deduced, that is, its orbital mode, take-off mode and pneumatic layout. The advantages and disadvantages of different modes are obtained by comparative analysis one by one. On this basis, the design concept of aerial aircraft is applied to the design of concept aircraft, and the basic shape of concept aircraft is determined by sketching. 3D modeling is carried out on this basis, and the feasibility of modeling is verified by Flame. Then complete the concept aircraft color rendering, detail texture display, and the final environment display.
