lol.
Yeah……
It would depend entirely upon which engines specifically you want to discuss and if they’re of similar size and if it is a high or low bypass.
Both use the same materials, and are both gas turbines. For example the maximum EGT of an A-10’s TF34 and that of a T700 series such as in the H60 and AH64 family are very close. Infact the T700 can actually be run hotter in some situations/conditions because she’s newer 495-695 C vs <866 C.
Outside of afterburners, they are very similar.
Parts of them are, not all of them. Hence the whole there are some missiles that can lock onto the friction of them.
While the TBF engines are quite a bit different then TBJ engine you still get something like EGT 120 degC on A-10, while on the T700 on AH-64 you’ll get EGT under 60 degC.
Why?
Even when TBF engines has around 30% of thrust generated by the engine core which means hot gases streaming from rear of the engine, while TBS engines you don’t want any thrust, you want torque, that means bit differently designed turbines section where in case of TBS engines gases are more expanding in a turbine, therefore cooling. HIRSS then cools the EG even more.
Sound like to BS to me, seeker would lock in a blade which has fed deg above environment, instead of the diffuser which would have 60+ degC?
To be clear I think helis are hot enough in WT, probably even hotter then IRL, but problem is with the seekers.
It’s a picture. There isn’t a magical way to tell.
Lol.
As a 20+ year army aviation guy, who is a qualified armament officer as well as an A&P. The answer is no. The unclassified/publicly released lock on/WEZ of the Stinger against a helicopter is 5 miles (8KM) and she’s one of the older (worse performing) missiles.
Especially when many of the included helicopters do not actually have HIRSS.
You realize that you can’t see the “diffuser” from many angles right? Missiles have developed specifically to counter the HIRSS we use. They also use different means to target
It may “sound like BS” to you. But as a guy who has spent over 21 years crewing the type of aircraft that is the prime target of MANPADS, I can tell you that the military has invested a lot of money and time into countering them, and teaching us how to evade engagement with them.
TBF engines are diluting the hot exhaust gasses with the bypass air just like HIRSS dillutes the helicopters. Even in a low bypass engine you’re pouring non combustion air into the exhaust, it’s just less of a ratio. And it’s not what missiles guide on.
Super old missiles like the SA-7, Red Eye and first gen Stingers worked primarily in the 3-5 um band, which is the product of heat seen from exhaust gas heating.
Newer missiles work in other bands that can even pickup “earthshine” which is the reflection of heat from the sky or ground on an object. Whether that’s what they’re seeing from the blades, or if it’s leading edge heat I can’t tell you. But I’ve watched the videos in our tactics instruction of multiple different missile seekers being trained on a helicopter and then how they handle the the effects of various defense techniques and IRCM.
TLDR, IR missiles in WT are under performing across the spectrum of seeker/flight/acquisition performance.
Well I mean it’s an AH64A or D, so it’s not very fast. Hell even the E models can’t break 175 knots in level flight. Very few helicopters are “fast”
279km/h
279 kph is 150 knots. That’s just about as fast as they can manage in level flight depending on engines health, and specific airframe mods/ external configuration.
With fresh 1.0 (or possibly better) motors, especially if you’re willing to take them into lockout (110% WEP in game) and jeopardize the health/longevity of them you could get a little more out of them in theory
I think the strongest SPAA in the game is: Low tier .50 cals and 20mms, big gap, first radar gun AA fighting fairly slow jets and lots of things with no RWR, the low tier stingers(and comparable systems) which absolutely slaughter in downtiers, then probably the very last AA.
The first radar AA and early stingers is the worst group IMO. Some planes and helis just can not do a damn thing with them around. Anyone else agree?
Helicopters can (and should) terrain mask.
Even without countermeasures most jets at early missile tiers can over G or extend out of missile range
Unless I can launch from an angle they can’t see or otherwise catch them unaware, my engagement % with early missiles (and the abysmal HVM) isn’t terribly inspiring.
That new Sikorsky/Bell whatever MOVES!
Im referring to helis like AH-1G, or really anything that wants to get in close.
Try out stingers, Igla, and especially the type 93. I have gotten smacked through dense clouds many times in my poor clueless Mig-17, Buccaneer, etc. Definitely feel better than before. The stormer HVM just needs to be put out of its misery.
If moving forward at speed, it’d have to be angled downwards more than it is in the picture.
nah. Stormer easily farms premium cas noobs, the problem is when the 1/100 pilots who actually know anything and are able to dodge Stormer, then it because impossible to kill them.
I don’t get it… I literally sad:
And you sad:
Which is what I said… the problem is with the seekers.
I would say whole airframe would be slightly heated up from various sources (avionics etc.)above the environmental temp, so I say it would be easier to lock on to this then on a blade which has very small profile from a far and requires high frame rate (low expo time) seeker to get reading from fast moving blade.
You
So do you counter MANPADS which are locking on the friction heat of the blades ? Besides fares and DIRCM?
I said the problem is more than just the seekers though.
The number one way to protect against missiles is to prevent them from being shot at you. Terrain masking, randomized flight paths, passive systems like HIRSS etc.
If one’s launched on you, your only hope is DIRCM.
