Instrumentation system for liquid dosing equipment utilized in combustion chamber of aircraft, has electric drives for controlling actuators, and flow meters utilized for calculating measured variations of flow of liquid

摘要

The system has a test bench for collecting measurements from a set of actuators i.e. servo valves, and an injection unit for applying an electromagnetic field to a dosing equipment at the time of pumping the liquid i.e. fuel. A set of electric drives is utilized for controlling the actuators corresponding to a fixed instruction (DEF). A set of measured variations of flow (MES-DELTA D) of the liquid is calculated by using a set of flow meters. An independent claim is also included for a method for measuring a liquid dosing equipment.
