基于FLIGHTLAB开发环境建立了直升机和舰艇之间的机舰配合系统仿真模型。按照相关要求开发了海面风场、甲板流场和舰船运动学系统仿真模型,编制了相关计算软件包,进行了机舰配合过程系统仿真的初步研究,并为舰载直升机训练模拟器配套了系统仿真软件。数学模型中包含直升机飞行动力学仿真模型、局部非定常舰面效应仿真模型、甲板流场仿真模型、海面紊流模型、舰船运动学数学仿真模型以及海面风场仿真模型,各模型定义在统一仿真空间内,实现了模型之间的时空无缝交联。基于上述仿真模型,开展了机舰动态配合仿真计算、舰面起降过程和包线分析计算,包括静态着舰过程及舰上操作仿真计算、机舰运动配合着舰等动态分析科目。该软件包已在舰载直升机综合任务训练模拟器上得到推广应用。
Based on the FLIGHTLAB development environment, a simulation model of the ship-ship coordination system between helicopters and ships was established. According to relevant requirements, the simulation models of sea surface wind field, deck flow field and ship kinematics are developed. Relevant software packages are compiled and a preliminary study on the system simulation of ship-ship coordination process is carried out. The simulation of ship-ship helicopter training simulator System simulation software. The mathematical model includes helicopter flight dynamics simulation model, local non-stationary ship surface effect simulation model, deck flow field simulation model, sea surface turbulence model, ship kinematics mathematical simulation model and sea surface wind field simulation model. Each model is defined in the unified In the simulation space, the space-time seamless cross-linking between the models is realized. Based on the above simulation model, dynamic simulation of ship-ship interaction, ship take-off and landing process and envelope analysis and calculation are carried out, including static landing process and simulation calculation of shipboard operation and dynamic analysis of ship-ship movement and landing. The software package has been widely used in carrier-based helicopter comprehensive mission training simulator.
