RD93 is useless,I want to meet those genius guys.RD 93 is mature engine and as of now only reliable,tested and used it newest version RD33mk solves many issues,like fuel consumption and smoke.Current Mk engine produces 7%more thrust then earlier model's.It is equipped with FADEC.
How do you know this? Acceleromters onboard RD93 monitor shaft balance either HP or LP. Imbalances trigger red inflight alerts. Usage monitoring system which can vary from flight to flight by as much as a factor of 70-100, accurately records and responds post-combustion lightings, engins starts etc. High cycle fatigue models have been very accurately determined for RD93. Dual redundant PMMs - performance monitoring modes pickup sequence anomalies in ignition, overheating, throttling failure, stall, delayed start, long and short rotations, turbine heat-vent failure, ECU overheating, compressor stalls, HP and LP overspeeding. Control-loop malfunctions are observed and minized by dual redundancy.
