The time between overhauls is dependent on so many variables. Like the load on each compressor- and turbineblade, temperatures, etc. so you could build a much more inefficient engine which has less compression ratio, less RPM, less combustion temperature but a much higher time between overhauls as the load on all components is less.
The power rating of the EJ200 is, compared to other engines (weight and size), at the upper end of so it doesn’t really suprise me that they have shorter timespans between overhauls. The load on all components is just that high.
Comparison:
F100-200:
Compression ratio of 24:1 with a 88 cm inlet with 3 + 10 compressor stages and 2 + 2 turbine stages with a turbine inlet temperature of less than 1620 K (the 229 has 1620 K so I assume the 200 has less).
EJ200:
Compression ratio of 26:1 with a 74 cm inlet with 3 + 5 compressor stages and 1 + 1 turbine stages with a turbine inlet temperature of ~1800 K.
Meh, to me it seems reasonable, the engine was designed for a 6000 hour lifespan, which is 30 years of operation according to MTU, so a major overhaul every 10 years.
The question is: Compared to what? An old or a comparably modern engine (F119/F135)? The thorttled version of the EJ200 (60/90 kN) or the unthrottled variant (69/95 kN)?
That is a very flawed methodology. There is no good way to compare TACs to flight hours because the number of TACs consumed per flight hour varies MASSIVELY depending on the type of flying being conducted.
And you can’t use servicing intervals to compare TACs to hours because some tasks need doing depending on engine run time and others depending on the cycles. Hence you never see that table directly compared TACs to hours.
The community seems to be entirely against aircraft getting a single bug fix. All the people in the BOL Thread with lines like “CAS must suffer” is rather funny, but also really sad. Let alone even mention of A2G buffs
Likewise, we’ll have to wait and see if we even get Aim-120C5s. The Typhoon might be about to officially become the second weakest 14.0 in the game, maybe even the weakest if PL-12 and AAM-4 get buffed
Here I could be wrong, but I don’t think it’s really nessecary to state a fixed number of cycles for the EJ200 as this engine has a rather extreme amount of sensors built in and a control unit which monitors all engine parameters in realtime and in turn calculates the wear of the components. So only if a certain value of one or multiple parameters is reached, maintenance or an overhaul is nessecary. It even records the history of that said engine from environment parameters over g-forces to engine settings. This would be called “predictive maintenance” and is dependent on the actual wear the engine was submitted to and not some fixed expected numbers like cycles or flight hours for “this type of engine”.
Ok Typhoon team we need something.
Brimstone 2 does it have reduced IOG drift, are we just cooked until SPEAR 3? How could Gaijin just screw over the EF so much?
This is what Su-30SM Kh-38ML with GNSS will be doing if this goes to the live server.
Where we not refused accurate Brimstone for this exact reason, you would be able to attack targets and they would have no hope of shooting you down…
