本文总结了Helios 2.0版（或Shasta）旋翼模拟软件的功能和发展。Shasta的具体功能包括离体自适应网格细化和处理多个相互作用的旋翼机部件（如机身、旋翼、襟翼和悬挂物）的能力。此外，还增加了一个新的运行模式来处理机动飞行。对Helios接口进行了根本性修改，以简化这些功能的整合。在近体解、离体解、域连通性、转子流体结构接口和综合分析的基础模块中也进行了各种修改，以适应这些接口并提高操作鲁棒性和效率。结果表明，网格自适应功能的软件NACA 0015机翼，TRAM转子悬停和UH-60 A在前飞。
This article summarizes the capabilities and development of the Helios version 2.0, or Shasta, software for rotary wing simulations. Specific capabilities enabled by Shasta include off-body adaptive mesh refinement and the ability to handle multiple interacting rotorcraft components such as the fuselage, rotors, flaps and stores. In addition, a new run-mode to handle maneuvering flight has been added. Fundamental changes of the Helios interfaces have been introduced to streamline the integration of these capabilities. Various modifications have also been carried out in the underlying modules for near-body solution, off-body solution, domain connectivity, rotor fluid structure interface and comprehensive analysis to accommodate these interfaces and to enhance operational robustness and efficiency. Results are presented to demonstrate the mesh adaptation features of the software for the NACA0015 wing, TRAM rotor in hover and the UH-60A in forward flight.
