Passing from a non-synchronized state between an engine and a rotor to a synchronized state
Abstract:
In order to regulate a power plant (105) having a gas generator (1) and a free turbine (3) to drive a rotary wing, a first speed of rotation (NTL) of the free turbine (3) is regulated on a first setpoint value (NTL*) equal either to a regulation term (NRc) or to a predetermined setpoint threshold (NTL*). The regulation term (NRc) is a function of a third speed of rotation (NR) of said rotary wing in accordance, where NRc=NR*(1−d), “d” representing a non-zero constant lying in the range 0 to 1.
Abstract(Chinese):

为了调节具有气体发生器（1）的发电厂（105）和用于驱动旋翼的自由涡轮机（3），所述自由涡轮机（3）的第一转速（NTL）在第一 设定值（NTL *）等于调节项（NRc）或预定设定点阈值（NTL *）。 调节项（NRc）是所述旋转翼的第三旋转速度（NR）的函数，其中NRc = NR *（1-d），表示非零常数在0范围内的“d” 到1。
