某型舰用燃气轮机起动机的选择

Selection of startors for marine gas turbines

本文试以某型舰用燃气轮机起动机的选择为例,着重叙述如何从发动机起动时的动平衡条件出发,应用均匀加速的原理,估算发动机的需用起动功率以及如何选择满足舰用条件而功率又较为合适的起动机。

Taking the selection of a startor for a certain type of naval gas turbine as an example, this paper focuses on a method for evaluating the required engine start power by using uniform acceleration principle with the dyna- mic balance condition during engine start-up serving as a calculation basis. The selection of startors which can meet marine use requirements and also have a relatively adequate power is also discussed in this paper.
