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

[MythicPi]

Different way of getting an object to do a thing basically.

Simplest/best example I’ve found explaining it is this one from a reddit post:

Spoiler

All control systems work by looking at the current state of the system and the state you want, then applying a bunch of math to figure out how to alter the system (using actuators) to get the current state closer to the state you want. The difference between PID and H-infinity theory is the kind of math you apply.

In PID, you look at the literal difference (the desired state minus the current state). You use that difference three ways. The “P” part of PID is Proportional. Multiple the difference by a number you choose and you get a value that’s proportional to the difference. You also calculate the Integral (“I”) and Derivative (“D”) of the difference and multiply those by numbers you choose. Sum all that stuff up and you get a value that you feed your actuator. The art of PID control, then, is to choose what numbers you multiply the terms by so that you get the results you want.

In H-infinity control, you’re not constrained to just work with the pure difference between the current and desired state, and you don’t need to just multiply by a few chosen numbers. You set up a matrix of possible things you can do and then use optimization (a mathmatical procedure) to find the values in the matrix that give the results you want. The art of H-infinity is setting up the correct optimization problem; you don’t actually pick the values, they come out of the optimization.

PID is simple (so you can execute it on cheap hardware) and easy to understand (so you can teach it and troubleshoot it easily). However, it’s hard to extend it to complicated multi-variable systems and since you’re just using substraction and straight multiplication you’re limited in the amount of neat things you can do.

H-infinity can handle much more complicated systems and lets you define the problem in terms of the results you want at the end, so there’s less iteration. The cost is much higher complexity to figure it out and to run it, so you need more capable and expensive tools to develop and run it.

Sorry for the late reply

SPEAR this patch?

Spoiler

[MythicPi]

Only place SPEAR would actually be useful would be air sim, and even then, the small payload likely means it could be very hit or miss.

Theoretically though, it would provide a challenger to the SDB-1’s in battlefield clearing, which would be interesting.

I’d love to see an EFT using the quad racks for SPEAR though. The triple racks are nice, and likely more than enough for IRL roles, but in WT, the triple racks means the EFT needs to carry the full 6 stations to clear a battlefield iirc, which cuts down your already meager ARH load from 6x down to 4x, and your total AAM count from 8-10 down to 6.

Im hoping for them in a purely GPS-Only GBU-39 style weapon where they should be fine in most gamemodes, if nothing else as decoys.

[ÖL]

Ah thats sad… i would love to have 4 more aim 120…

[Dontkev-psn]

Well, you can pick up to 6…

[ÖL]

I know? Haha

When the iris t comes. Will it be able to be on a dual rack like the sim 9m?

[ILuvAnneHathaway]

most likely

[ron_23]

is the asramm be able to?
or does it use a different launch rail from the sidewinders unlike the IRIS-T

[ILuvAnneHathaway]

No idea tbh

[Tea_And_Country]

i think wherever an aam9 can fitt an asraam can.

[Mytho-GR1]

ASRAAM works on the same rails as any AIM-9M

[Smugspite]

funny enough im pretty sure the dual rack was a liberty gaijin took because I know the dual rack was for ASRAAMs

[ron_23]

the picture of the dual rack we have carries the IRIS-T

and the IRIS-T uses the same launch rail as the sidewinder,
it was able to be fired by the F-4F ice without modifing the launch rail

[Morvran]

ASRAAM and IRIS-T were specifically designed to be intercompatible with Aim-9.

[Smugspite]

fair enough

[Smugspite]

considering gaijin has kinda just combined all of the EFT variants I wonder if they will all get IRIST and ASRAAM because if they do, I assume the “meta” loadout would be 4 Meteors, 4 ASRAAMs and 2 IRISTs

[Morvran]

We’ll have to wait and see. I hope they dont, not only because thats a balancing mess, but also gives a reason to fly more than 1 Typhoon and in SB, it creates asymmetry between FGR4 and EF-2000

[Dontkev-psn]

@ron_2303

it was able to be fired by the F-4F ice without modifing the launch rail
