Title:
【発明の名称】ヘリコプターの高速ロータ荷重で速度を増大させる装置
Document Type and Number:
Japanese Patent JP3130029
Kind Code:
B2
Abstract:
A helicopter engine speed reference (66) is increased (113, 103-105) in response to heavy rotor loading (108). The reference speed is faded up (113, 104) at a rather rapid rate to 107% of rated speed (114). After a fixed time interval (118), reduced rotor loading (119) will cause the reference speed to be faded down slowly (120, 103-105) to rated speed (121). If torque exceeds 111% of rated torque (117), the reference speed is similarly faded down (120, 103-105).
