Eurofighter Typhoon (UK versions) - Technical data and discussion

Аnd one more question about the RWR. One of the features of the 4+ generation is the fusion of sensors.
Actually, the question is - can the IRL radar be aimed at a threat that the RWR has noticed? Provided that it is in the radar coverage area. As far as I remember from the presentations, the DASS determines the position of the threat in 3D space. This means that the onboard computer has information about the position of the threat and theoretically, using this information, the radar/IRST can be aimed at this threat.
The question is: can he do this or do my conclusions have little to do with reality?

Because that’s an accurate summary. No idea what planet the other guy is living on.

They’re heavily limited in range by the automatic self destruct, require laser guidance and travel slower than hellfires. The only time wherein they are good is as I said before (no pantsirs) as NATO SAMs are woeful and if there are no SAMs up at all obviously you’ve just got impunity to throw them out at close range.

Any FnF forget weaponry is far superior given you can fire off your munitions and very quickly cycle sorties. The 6x hammers of the rafale or 6x MTs of the SU-34 are far superior given you can engage from outside pantsir range and immediately go re-arm for round 2.

If you are banking on the enemy having no pantsirs up for a weapon to be good then it’s not a good weapon.

(Having checked the guys replays it all makes sense, guy is just playing squadded with someone who plays russia so the pantsirs are always on his team. Figures.)

You mean RB199’s? Feel free to share the documents if it’s not an issue.

What I’ve found for British requirements of a future combat aircraft at the time were as follows;

Similar to what is being shown in his report, approximately 29.5 deg/s instant turn rate at 9G and ~0.5 mach SL. Interestingly, the rest of the data aligns itself quite neatly with expected Eurofighter performance and yet the sustained turn is only 18.5 deg/s at 9G.

No, not RB199, EJ200, but the engines were considered downrated for the performance review to account for the engines not completing development and wearables.

It is EJ200

There is a reason why your ramblings were removed

Should it sustain more than 9G past 1.2 mach?

The full design requirements document for the Eurofighter (known as the ESR-D) has been declassified and many copies of it can be found in archives.

Here is a summary of the turn performance requirements.

So it is heavily overperforming in-game at very low and at high speeds.
The excess power is incorrect as well.

Do you have an excess power report prepared?
Do you have a radar cross section reduction report prepared?

In particular, it should have 1/4 the RCS of the Tornado as I tagged you on discord with Austrian official’s claims of such being a requirement. I assume you have something on that of your own.

Not quite the the full picture, that’s just the requirements… not what EFA achieved…

The SEP is actually close to correct. It’s just too low at Mach 1.6/11km

I have no means of testing Specific Excess Power. I don’t personally use WTRTI, and even if I did the devs chuck out reports based on WTRTI.

It is also my understanding that the localhost data output of the game does not provide specific excess power, so that is not an option either. WTRTI apparently extrapolates SEP based information it does have (rate of climb, acceleration, etc.)

I responded on discord.

And no it’s underperforming at low speeds, especially at altitude:
200knots/6069m - 8.9°/s - should be >13°/s

You are not looking at the full range, only your datapoints

What full range? That is the only low speed datapoint you’ve been shown.

Extrapolate the in-game data yourself and find a conclusion based on the rest of the source you’re using

lol at the heavily over performing comment when it’s simply the requirement it needed to meet and which even the prototype with less power exceeded

Feel free if you’d like to test against the min radius data.

If there’s a chart for SEP it can be tested by measuring velocity changes while pulling a turn with constant G pull or constant turn rate (degrees per second).

m\,g\,h = \dfrac{1}{2}\,m\,V^2
\dfrac{d}{dt}m\,g\,h = m\,g\,\dot h = m\,g\,SEP(V) and \dfrac{d}{dt} \dfrac{1}{2}\,m\,V^2 = m\,V\,\dot V

m\,g\,SEP(V) = m\,V\,\dot V

\dfrac{dV}{dt} = \dfrac{g}{V}\, SEP(V)

\displaystyle\int_{v_0}^{v_f} \dfrac{V}{SEP(V)}\;\mathrm{d}v = \displaystyle\int_{t_0}^{t_f} g\,\mathrm{d}t .

\dfrac{1}{g} \displaystyle\int_{v_0}^{v_f} \dfrac{V}{SEP(V)}\;\mathrm{d}v = Δt .

One “just” (it’s actually fairly annoying to do) needs to do a turn with constant pull/turn rate and measure the time it takes to get from speed A to speed B and compare it to what the equation above gives
