单桨双机推进系统中单机突卸时的主机保护

Protection of Main Engine in a Propulsion System with Twin Engines Geared onOne Propeller Shaft When One Engine is in failure

当双机单桨(单调距桨)推进装置在正常满负荷运行时,如果一台主机突然脱开,可能会引起另一台主机损伤。本文在介绍瑞典KAMEWA公司的ERC-1控制系统工作原理的基础上提出一种有效的保护方法——单机最大螺距限制。

Based on the operation principle of KAMEWA ERC 1 control system, an effective method is introduced in this article to protect the main engine in a propulsion system with two engines geared on one CP propeller shaft in case the system is running normally at full load with one of them declutched suddenly.
