AI Technical Summary
Technical Problem
Existing methods for regulating the thrust of aircraft turbomachines at high dilution rates are inefficient due to large propeller inertia and imprecision in blade setting, leading to slow thrust variation and yield penalties.
Method used
A method involving open-loop regulation of thrust by varying the timing of the rectifier's blades and closed-loop calibration of propeller blades based on rotation speed, along with optional regulation of fuel flow to maintain a constant N2R/N1R ratio.
Benefits of technology
This method provides precise and effective thrust regulation, reducing propeller inertia effects and improving yield stability by directly acting on the rectifier's timing and propeller blade calibration.
