舰船空气流场是舰载机起降安全的重要影响因素,其结构化建模是研究舰载机起降安全边界和起降动力学过程的重要支撑。直通甲板舰船的空气流场结构化建模问题已于20世纪80年代解决,并纳入MIL-F-8785C军用规范,得到了广泛应用;而非直通甲板舰船的空气流场结构形式更为复杂,近年来科研人员通过数值模拟、风洞试验或实船测量等方法开展了研究,但其结构化建模问题仍有待解决。本文的研究目的是探索非直通甲板舰船空气流场的结构化建模方法。通过对其流场结构、形成机理进行分析,采用流场特性频域分析和数据拟合方法,解析了流场的稳态、周期和随机分量,成功构建了流场结构化模型,并通过仿真验证了模型的有效性,初步解决了非直通甲板舰船空气流场结构化建模问题,得出了较为实用的结构化模型,有望为舰载直升机起降安全研究提供重要支撑,大幅减少机-舰动态配合试验的工作量,使机-舰组合风限图的制定更加高效,并为机-舰动态配合实时仿真奠定基础。
Ship airwake modelling is essential for studying the safe operational envelopes and dynamic processes of shipborne helicopters’ taking off and landing. The carrier airwake modelling was established in the 1980s and incorporated into the widely used MIL-F-8785C military specification. However
the airwake of non-aviation ships is much more complicated than that of carriers. Even though extensive numerical simulations
wind tunnel tests and at-sea measurements have recently been conducted
a practical model for non-aviation ship airwake has yet to be developed. Spectrum analyses conducted by this paper reveal that the non-aviation ship airwake can be decomposed into steady
periodic
and random components
whose formation mechanisms have been discussed. Based on these findings
this paper proposes a practical mathematical model of the non-aviation ship airwake that has been verified through numerical simulations. The model is proven to significantly improve the efficiency of establishing SHOL (ship helicopter operational limitation). Therefore
it is expected to support the research on the shipboard helicopters' taking off and landing safety.
