Su-33 PFM

[Hyperion35]

Is it currently possible to take off from the carrier deck with the PFM? I can't get enough speed. I've tried taking only half of a fuel load.

 

Yes, I've taken off with about 60% fuel load and a full set of missiles. But it took several tries to get it right, and even then it was a close thing. I'm not sure if this is because it's a WIP or if this reflects the very real fact that the Su-27 airframe was not originally designed for STOBAR.

I did a test:I recorded a .trk with the AFM (a bad take-off) and then played back the .trk with the PFM.

 

The outcome is interesting!

You guys might have the PFM, but you might be missing other aspects of the updates to the Su-33, remember their are some system updates as well, and the key bindings to go along with them.

Yeah, cannot wait for the PFM to come out officially! It's already a great sneak peak as it is... :)

What was interesting to me is that I found the PFM version easier to control. Had no trouble taking off with missiles and 40% fuel. Also fun on a moving carrier, since it doesn't seem to be "sticking" to the deck.

Agreed. I believe the canards add to that initial stability getting off the ground, as the nose-down tendency is suppressed some compared to the Su-27. Very nice. Overall, the 33 feels quite stable.

[Vitormouraa]

In theory the 33 bleeds off more energy than the 27 no?

Do you have to turn around first and get some extra runway length to take off from the carrier? I can't take off successfully from the ramp position with 50% fuel and no missiles.

[NineLine]

Do you guys see War Power as an assignable option in controls? That might be missing, and might be the issue.

I don't have to turn around because, with the moving carrier, I stand still while it passes under me. :) But it looks like I'm rolling backwards...and brakes seem to have no effect on the motion.

 

By quickly jamming the throttles forward as soon as I was in the pit I was able to take off more or less from the normal position. But that's 40% fuel w R-73*2, R-27ET*2 and R-27ER*4. I seem to recall reading somewhere awhile ago that the normal procedure was to takeoff was with 30-40% fuel and, then, aerial refuel before conducting the mission. But I don't remember where I read it or how valid the info might be.

 

EDIT: Carrier was moving at 25 km/hr into a 5 m/sec (18 km/hr) wind. So 43 km/hr wind coming over the deck to assist. It may be that, with the PFM, you now have to pay attention to things like that.

As in extra thrust? Not home, so I can't check right now.

Ahh, OK. I was using a stationary carrier with no wind. I'll experiment some more when I get home tonight. I'll check for war power as well.

[NineLine]

If you can find it, you probably need to be using that, full AB and War Power, if you dont have it, it will come with the actual release.

 

[*]The engines now have a “special mode” that adds up to 12,800 kg of thrust (instead of the normal 12,500 kg of thrust). This mode also includes realistic operating time restrictions.

War Emergency Power: LShift+E

[mvsgas]

Many of the video I seen posted here, it seems that it is normal for the aircraft to take off from the rear position, there has to be a reason for that.

Several examples here

In that video you can see the fuel gauge marking 6.000 Kg fuel and landing with arund 2.500 kg.

War Emergency Power: LShift+E

 

Did that help at all? It still might just be that its not a full release of the FM.

[finch]

I have no problems taking off from the moving carrier with this configuration

[hornet1a]

Emergency military power (L shift+e) engage only when you are at full after burner.

 

Also if you hold (L shift+w) "wheel brake start" according to the axis indicator

it increase the braking power,useful if you want to take off from the carrier.

 

So to take off from the carrier:

-Hold L shift+w until the engines are at full after burner

-Release L shift+w and then engage the emergency military power...

Try to take off:should be easier now!

[Ironhand]

Seemed to. Only tried a few comparisons but seemed to sink less after leaving the ramp when using that key combo.

Emergency military power (L shift+e) engage only when you are at full after burner.

 

The engine feature in question is called "чрезвычайный режим (ЧР)" in Russian, which I believe simply translates to "emergency mode".

 

Its an extension to the engine's afterburner regime, which in turn is separate from the normal thrust range for which "military power" is the max setting.

[AG-51_Razor]

Whatever happened to the chocks that come up to engage the main landing gear? I haven't seem them come up in quite some time. They used to appear after hitting the "U" key I believe. I even called the tower for takeoff permission, which brought the Jet Blast Deflector up but still no chocks.

The AL-31's have a War Power/Overdrive mode w/ Limited time of operation (to avoid damage to engine).

AFAIK the chucks were the same as used when the aircraft is parked and are part of the aircraft 3D model(added/removed via visibility argument).

 

So maybe ED removed their appearance from the carrier logic in preparation for the arrival of the new aircraft carrier model(with the proper chucks)?

The AL-31 as such does not - only the one used on the Su-33.

 

Its not a "War power" mode, but an "Emergency mode" with the primary purpose of ensuring safe take-offs from the aircraft carrier and recovery in case of a "bolter".
