42 years maintaining aircraft. Allow me to enlighten you. The first scenes were of Radio Controlled jets, with very skilled operators. They do actually make fuel burning turbines in some of them, most definitely in the 6 or 8 foot models, which can cost tens of thousands of dollars. The later scenes were of an actual plane and the puffs of smoke are from a black powder cartridge starter system which uses the burning gasses to spin the compressor section of the turbine so that it will be moving air fast enough to allow fuel to be introduced and the start sequence to continue building RPMs. (Too much fuel at too low of an rpm with cause heat damage to the turbine blades at the aft end of the turbine section.) All commercial jets use a small turbine engine in the tail, called an A.P.U. for auxiliary power unit, that can be started with either the onboard batteries or a ground based start cart that can supply electricity for starting. 6park.com
42 年维护飞机。 请允许我为您解惑。 第一个场景是无线电控制的喷气式飞机，操作员非常熟练。 他们确实在其中一些制造燃料燃烧涡轮机，最肯定的是 6 或 8 英尺型号，这可能要花费数万美元。 后来的场景是一架真正的飞机，烟雾来自黑色粉末筒启动系统，该系统使用燃烧的气体来旋转涡轮机的压缩机部分，这样它就会以足够快的速度移动空气以允许引入燃料和 继续构建 RPM 的启动顺序。 （在过低的转速下过多的燃料会导致涡轮部分后端的涡轮叶片受热损坏。）所有商用喷气式飞机的尾部都使用小型涡轮发动机，称为 A.P.U。 对于辅助动力装置，可以使用车载电池或可以为启动供电的地面启动车启动。
