- 以某气垫船推进装置为研究对象，以提高其推进效率为目标，开展推进装置气动力理论优化设计与风洞试验验证工作。首先，基于B样条参数化方法，对推进装置的导管外形进行参数化建模，获得B样条控制参数，并将其定义为优化设计变量；其次，基于试验设计方法DOE、B样条参数化方法和数值仿真方法，开展导管气动力优化设计，形成理论优化方案。最后，设计制作缩尺模型，开展风洞试验，进一步验证理论优化方案的可信度。研究表明：导管外形对其自身以及整个推进装置的气动性能影响明显；通过精细设计导管外形，可以获得更高的推进效率；优化导管外形之后，气垫船推进装置的推进效率明显提升，其中额定功率下的总推力可提高约3%。
Taking the propulsion system of a hovercraft as the object, and aiming at improving its propulsion efficiency, the aerodynamic optimization and wind tunnel test verification work were carried out in the paper. Firstly, based on the B-Spline parameterization method, the duct shape was parameterized, and the control parameters of B-Spline were obtained and defined as the optimization variables. Secondly, by combining the DOE (Design-of-Experiment), B-Spline parameterization and numerical simulation methods, the duct shape was optimized and the optimization scheme was put forward. Finally, the wind tunnel test was carried out to further verify the reliability of the optimization scheme. The results show that the duct shape has significant influence on the aerodynamic performance of itself and the whole propulsion system. By carefully designing the duct shape, higher propulsion efficiency can be obtained. In the paper，the total thrust of the propulsion system on a hovercraft can be increased by about 3% at the rated power through the duct shape optimization.
