Eurofighter Typhoon (UK versions) - Technical data and discussion (Part 1)

had the same issue too, even on the smaller and faster scan it would drop/forget targets super easily even in a head-on ~25km out

I made this bug report agian bc it seems like it isnt getting noticed.

If you want to read more about the EJ200 and why its designed how it is, you can read about that here: https://web.archive.org/web/20140520001842/http://ftp.rta.nato.int/public//PubFullText/RTO/MP/RTO-MP-008///$MP-008-02.pdf

Additionally: I remeber you saying (maybe in the other EF thread), that the Convergent-Divergent-Nozzle wasn’t optimal for supercruise/supersonic. In contrast to that, the source (and everything else I found about that) states that this C-D-Nozzle was chosen because of its supersonic capability in enhancing the endurance by 25% and reducing the tail air drag of the EF opposed to other nozzle designs.

I think it’s because they’re slow moving mig15. I had the same issue while testing the Rafale in the test drive. The TWS struggle to keep them updated, and Rafale’s scan rate is easily two time faster than the EFT.

IIRC the test drive Mig15 keep a constant speed of 500km/h.

How is the radar? Is it fixed… is it quick like it is everywhere written when talked about its scan speed? Or its just LAZY copy paste of blue vixen.

This looks a lot like a copypasta of the Gripen radar. Let’s play a game? I’ll send you 2 gifs of the radar in action, and you’ll guess which is Typhoon and which is Gripen?

You joking right??? That thing should be capable of combining AG/AA modes with good refresh speeds.
Are gaijin devs on drugs again?

No A/G. At all

Would explain how they came up with thrust/intake losses of 13,5% dry (6118 kgf uninstalled, 5390 kgf installed) and 11% wet (9177 kgf uninstalled, 8260 kgf installed) for the engine.

The convergent-divergent is great for supersonic afterburning performance but is actually inferior to the other designs for supercruise in particular. The most optimal is a design similar to the F-22’s.

This is a good document, thank you. Now we can see that the two documents align quite well and it is explicit that the EJ200 was described in my previous post.

It is clear, the EJ200 is not well optimized for supercruise. If it were better optimized, the bypass ratio would be smaller. The pressure ratios and temp limits would be retained, but there would be heavier focus on dry thrust and this would require a lower T3 temp, higher SOT, and inferior TSFC during afterburner operation to achieve the same afterburning thrust capability. They simply had hard requirements to enhance the SFC during dry operation as well as during afterburner. They simply could not meet subsonic cruise SFC requirements and supersonic re-heat SFC performance without the larger bypass ratio and within the temperature limitations.

It is this bug (go up the chain of replies a bit for more details).

There is a typo in radar’s config file (only on the Captor-M with Pirate, for some reason) that sets the time it takes to clear a target that the radar has not updated to only 4 seconds. So every time you have a TWS target that the radar was not able to update in 4 seconds, it just clears that contact off of the scope. It also centers the scan area if you have have target cycling turned on (you don’t manually move the pipper).

Which likely means it cannot see helis in TWS mode :(

Where is Typhoon’s radar and where is Gripen’s? No joking

Gripen radar is pretty mid too, dont even use TWS with the R-Darter as it always loses track and just misses.

That thing is a C-D-Nozzle, just it being square to help mixing jet exhaust and surrounding airflow to minimize the IR-signature. Especially as the aerdynamics should be worse for a square exhaust as it induces wake vortices at its corners which is the reason it helps mixing the different airflows.

The Bypass ratio of 0,4:1 of the EJ200 is for one just minimal different from the F119 with 0,3 and second it was chosen as a compromise to accomodate bigger engine cores for future developments. The difference in supercruise capability shouldn’t be more than a few percent in this case as the Fan of the EJ200 compresses even better than the F119 Fan.

jesus Fk… they really cant do anything right can they

Any news on when they are fixing the scan pattern (double scanning of upper and lower row)? This is bugged since forever…

The F119 has lower T3 and higher SOT aiding dry thrust. The excess dry thrust pushes a draggier airframe to 1.7+ mach supercruise. This is aided heavily by the lower bypass ratio. If it was only a few percent better it would not have such raw performance benefit.

I was under the impression the convergent-divergent nozzle of the Eurofighter is not fully variable and that was one of the upgrades that set apart the TVC nozzle upgrade theorized for it.

But hey… they told ut that radar is WIP… SURPRISE, its same S**t as it was on dev.
