转官方贴:FC3导弹高级气动模型的详细讲解

太专业了,谷歌翻译的看不懂,求E文高手翻译。

There have been a lot of questions of what the new FC3 Advanced Flight Model (AFM) for missiles entails, so here is description of some of the new features:

[*]Launcher platform speed, thrust, missile weight, total drag, gravity, etc. are all calculated to determine missile speed.
[*]Missiles now incur realistic energy bleed that accounts for drag, induced drag and gravity. Induced drag calculates g-load and that factors the missile’s lift. Missiles will now bleed energy very quickly if the target performs hard maneuvers.
[*]We added a longitudinal-load fuze arming type. The missile warhead of missile will only be armed after reaching the assigned longitudinal g-load (acceleration). Otherwise the missile will not detonate.
[*]We added a limited duration to the missile’s power system (gas-generator, generator and hydraulic pump). When the onboard power system is exhausted, the missile goes ballistic.
[*]We added a self-destruction timer. Some missiles will self-destruct when the timer is reached.
[*]We added altitude based of self-destruction. Some missiles will destruct when reaching an assigned altitude above ground level.
[*]We added a guidance timer delay. After launching a missile, the missile will fly straight from the from launcher for safety reasons before initiating the guidance stage. This is typically 0.3…1.5 seconds. For example: the R-27R missile flies unguided forward for 0.5 seconds before guidance to target starts.
[*]We added parameters of loft trajectory. The initial range to target, the range of transition to proportional navigation, and initial angle of loft are all factored.

关于新的FC3中空空导弹所采用的高级气动模型(AFM,Advance Flight Model),大家有许多问题,所以这里对这些新特性做一个讲解:

[*]导弹发射平台的速度、推力,以及导弹的重量,总的阻力和重力等等,都被引入了导弹速度模型的计算公式中
[*]导弹的真实能量消耗考虑了阻力、诱导阻力和重力的影响;诱导阻力会影响G值,从而影响导弹的升力,如果导弹的攻击目标做剧烈机动,导弹的能量会损失的非常快
[*]增加了新的纵向加速度激活的导弹保险,导弹战斗部只有在纵向加速度(G值)达到一定值后才会打开保险,否则导弹不会被引爆
[*]增加导弹动力系统(气体发生器、发电机以及液压泵)的工作时间限制值,当导弹机载动力系统消耗殆尽后,导弹沿原路线做自由落体动作
[*]增加了自爆计时器,一些导弹在达到计时之后会自爆
[*]增加了高度自爆器,一些导弹在降至指定的地面高度之后会自爆
[*]增加了导引头工作延时器。考虑到载机安全的原因,当发射后导弹会笔直往前飞一段时间之后导引头才会开始工作,这个时间一般为0.3到1.5秒钟。例如,R-27R导弹,在朝前飞离载机0.5秒之后导引头才开始指引目标
[*]增加了高抛弹道。距离目标的初始距离、转为比例导航的距离、抛物线初始角度等等因素的影响都被考虑

貌似 在FC2里的 R27系列的导弹比1.12的模型质量差多了,AIM系列就不会。。。

很好,很强大!!!早日离开2.0这个怪圈是一件大好事!!!:handshake:victory:
