摘要: 加油软管-锥套的气动稳定特性是影响软式加油对接成功率的主要因素,数值仿真和风洞试验是模拟软管-锥套收放过程、获取软管-锥套气动稳定特性、优化加油装置设计、发展加油对接技术的主要手段。本文采用基于气动建模的软管-锥套多体动力学方法对1:1全尺寸和1:11缩比模型的软管-锥套气动稳定特性开展了数值仿真模拟,基于动力学相似准则和OptiTrack光学测量方法对1:11缩比模型的软管-锥套气动稳定特性开展了风洞试验模拟,并对不同工况下锥套下垂量的数值仿真和风洞试验结果进行了对比分析及相关性研究。结果表明,1:11缩比模型的数值仿真与风洞试验结果一致性良好,验证了基于气动建模的软管-锥套多体动力学仿真方法的正确性;1:1全尺寸和1:11缩比模型的锥套下垂量归一化仿真结果在数值上存在明显差异,在随来流速度变化的规律上具有一致性,表明尺寸效应不可忽略,目前所建立的缩比软管-锥套气动稳定性风洞试验技术并不完备,需进一步开展尺寸效应修正研究。

Abstract: The aerodynamic stability characteristics of refueling hose-drogue are the main factors that affect the success rate of soft refueling docking. Numerical simulation and wind tunnel test are the main means to simulate the retraction-extension process of hose-drogue, obtain the aerodynamic stability characteristics, optimize the design of refueling device and develop refueling docking technology. Based on the aerodynamic modeling method and multi-body dynamics method of hose-drogue, the aerodynamic stability characteristics of hose-drogue for 1:1 and 1:11 of a tanker model are simulated. Based on the dynamic similarity criterion and OptiTrack optical measurement method, the aerodynamic stability characteristics of hose-drogue for 1:11 model are simulated by wind tunnel test. The numerical simulation and wind tunnel test results of drogue vertical displacement under different working conditions are compared and analyzed. The results show that the numerical simulation of 1:1 model is in good agreement with the wind tunnel test results, which verifies the correctness of the multi-body dynamics simulation method of hose-drogue based on aerodynamic modeling. The normalization simulation results of drogue vertical displacement for the full size model and 1:11 model are obviously different in numerical value, and are consistent with change of flow velocity, indicating that the size effect can not be ignored. At present, the wind tunnel test technology of aerodynamic stability of scaled hose-drogue is not complete, so it is necessary to carry out further research on size effect correction.
