模拟电子式？数字电子式？流体力学式的？

燃油流量控制，现代发动机应该是通过EEC控制HMU中燃油计量活门开度来实现的吧，老式发动机（CFM56-3）是通过MEC计算出来的，算是机械式的吧。不知道燃油流量控制器是什么东东，亦或是想说燃油流量传感器？

这个应该是EEC控制，HUM作动的
The electronic engine control (EEC) is the primary control for the engine. The EEC uses digital and analog signals from the engine and other airplane systems to control and monitor the engine. The EEC sends engine data to other airplane systems.

The hydromechanical unit (HMU) supplies fuel for engine servo system operation and combustion. The HMU receives fuel metering signals and engine servo command signals from the EEC and the airplane.

The HMU has electrical and fuel connections. These connect the HMU to the EEC, to airplane control systems, and to engine servo systems. These connections are necessary for correct engine operation.
These are the HMU hydraulic (fuel) connections:

流量控制器是一整套的系统，包括计量、计算和反馈。

是eec控制燃油流量吧

解答的很好

控制是通过控制活门开度实现，应该算是机械式吧
