摘要
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 software,a system simulation model for the helicopter/ship interaction procedure was established.Simulation models of wind on the sea surface and deck as well as the ship kinematics simulation model were developed according to some related requirements.The related calculation software package was developed.A preliminary study was done on system simulation of helicopter/ship interaction procedure for ship-based helicopters.The shipboard helicopter training simulator was equipped with system simulation software.Mathematic models include the helicopter flight dynamics,slantly dynamical and local Ship Ground Effect model,simulation model of flowfield on the deck,turbulent model on the sea surface,ship kinematical model and simulation model of flowfield on the sea surface.All models are working in the same simulation workspace,seamless connected with the same local position and time.Based on these simulation models,dynamic helicopter/ship interaction,shipboard take-off/landing procedure and flight envelope were calculated.Static interaction procedure,shipboard operation simulation calculation,dynamic helicopter/ship interaction of landing and some dynamic analysis subjects were included.This software package has been applied to the integrated mission training simulator of the shipboard helicopters.
