Eurofighter Typhoon (UK versions) - Technical data and discussion (Part 2)

where does it say its ±90* in the vid ?

[MythicPi]

Radars are installed at an angle in stealth jets because otherwise they’d be a large flat surface that reflects radar waves.

In this case, I’m assuming (though I could be wrong) that a more angled radar does a better job at deflecting radars waves than a less angled one.

@MythicPi

a more angled radar does a better job at deflecting radars waves than a less angled one.

Isn’t that up though? Most stealth radars from what’s I remember are angled up, not to the side to reduce rcs (eg su-57, f-22, f-35). Really only 4.5 gens use esa radars mounted in a gimbal. I think the reason for that is not stealth but for getting the most out of their one radar.
To be the most stealthy, it seems the way to go is to angle your radar upwards

[Mytho-GR1]

ECRS is angled up

it can gimbal left and right

The reason that most AESA don’t gimbal isn’t due to stealth but that most are from a decade ago

[kizvy]

We had esas mounted on a gimbal since the 90s, before fixed esas for stealth became a thing
Heck the su-30sm in game rn has a esa mounted on a gimbal

[Mytho-GR1]

Not a swash plate
and not an AESA

[ron_23]

there is a difference between mounting a PESA on a gimbal and an AESA on a gimbal

[kizvy]

@Mytho-GR1

Not a swash plate

What’s the difference?

[Mytho-GR1]

one provides a much better gimbal then the other

[ron_23]

@Mytho-GR1

one provides a much better gimbal then the other

that is not the difference

snail… I even wrote the correct name in there…

@Mytho-GR1

Irbis doesn’t use swash plate and has max scanning angle of ±125, much higher than the ±100 of the swash plate captor e
Wait does irbis even use a swash plate? Idek what a swash plate even does

[ron_23]

@kizvy

Idek what a swash plate even does

the swash plate is the thing rotating

@MythicPi

The Mk1 also has a swashplate tho, it can be seen in the video I posted earlier, but heres a gif of it:

[Mytho-GR1]

i mean with bars

[kizvy]

Yeah but irbis can also do that no? And that isn’t called a swash plate, at least I haven’t seen anyone call it that

[ron_23]

you made a generalization

basically saying that a design with a swash plate will always have gimbal

that was the question:

@kizvy

@Mytho-GR1

Not a swash plate

What’s the difference?

and this was your awnser:

@Mytho-GR1

one provides a much better gimbal then the other

[ron_23]

becasue it isnt

[ron_23]

again the swash plate is the thing inbetween the antenna and the plane that rotates to achive a radar gimbal

@MythicPi

The Mk1 also has a swashplate tho, it can be seen in the video I posted earlier, but heres a gif of it:

and it is pretty much the only way to gimbal an AESA radar due to how many wires are need for an aesa

[MythicPi]

A swasplate is an angled plate that turns a rotating input into a reciprocal output.

As for why a swashplate is used, I’m not sure if its exactly stated, but If I had to hazard a guess, its likely due to increased reliability and potentially also increased potential speed paired with the AESA’s electronic beamforming, as your input is always only a single thing (rotational input in either direction).
