The invention relates to a diversion trench device suitable for an offshore spaceflight launching platform, the diversion trench device is provided with a diversion trench structure with a herringbone cross section, the diversion trench structure is composed of a pipeline I, a pipeline II and a pipeline III which are connected in sequence, the inner side of the pipeline II is a smooth cylindrical surface, and the outer side of the pipeline II is an arc cylindrical surface; and smooth cylindrical surfaces are arranged inside and outside the pipeline I and the pipeline III. According to the diversion trench of the offshore launching platform, flames can be prevented from being directly jetted to the sea surface, meanwhile, the smoothness of wake flow can be guaranteed, more preferably, the optimal shape, size and angle design of the diversion trench is obtained through CFD optimization analysis, reasonable distribution of pressure and temperature in the diversion trench is guaranteed, and the service life of the diversion trench is prolonged. And the gas flow field is stable.
本发明涉及一种适用于海上航天发射平台的导流槽装置,具有一个横截面采用人字形的导流槽结构,所述导流槽结构由依次相连接的管道I,管道II,管道III三部分组成,管道II部分内侧为平滑柱面,外侧为圆弧柱面,管道I及管道III部分内外均为平滑柱面。本发明提供的海上发射平台的导流槽,不仅能够避免火焰直接喷射海面,同时能够保证尾流的通畅,更为优选的,本发明经过CFD优化分析,得到最优化的导流槽外形,尺寸以及角度设计,保证了导流槽内压力以及温度的合理分布,以及燃气流场的平稳。
