Yes yes yes! K-14! Big Grin We need it, we want it!

yes very true Big Grin

Need it... not really. Want it... for sure!

Jumping in the bandwagon, i give this a big bump!

(Yes i know, sorry for being off topic, but this should be definitely doable and a really nice and welcomed addon)

EDIT: i see that my post sounds like demanding something, like all the others just this week have.
I am NOT demanding something or nagging (well, not trying to), just asking nicely. 8)

Mate this is a ripper mod! Can I offer some constructive criticism? The fuselage needs to be deepened a shade (for a clean incorporation of the oil cooler), and the nose lengthened (for the much longer DB-603 based engine). Are you modelling the P.1091 (605 engine) or P.1091a (603 engine)?

I'll assume it's a 1091a with the 632 engine. This actually an adapted 603N which is itself a high octane, high performance version of the 603LA used in the Ta-152, with a two-stage mechanical compressor, an additional turbosupercharger housed in the fuselage (fed by the external exhaust ducts) and an intercooler (total of 3-stage multispeed pre-induction compression). Outputs were expected to be 2400PS at take off and 3200rpm with 1520PS at cruise. It is the engine Kurt Tank had once dreamed about for his Ta-152/153 project. At around 15,000 metres it ought to have put out somewhere in the region of 1900PS (the low-octane 1660PS 603U single prop alternative tested 1430PS at that height for a top speed of around 690km/h). With the 632 engine top speed should be in the order of 725km/h or more but that's not the real benefit of the P.1019, it's altitude performance made the Ta-152H look like a try hard and the design held real benefits in the realm of high altitude strategic reconnaissance. But development was years away at best and it would not be ready for service late in 1944 as requested by the RLM.

Blohm and Voss tested turbosupercharged 603 engines for their BV.155 (ex-Me 155) project. They initially used what seems to be a DB-627 motor (could have been 603S but I think that was the failed Fw-190C engine) based on the 603A but found engine cooling with the turbosupercharger was a critical issue. They later repositioned humongous underwing radiators and switched to the 603U engine based on the 603E, which had a much larger mechanical compressor and higher rated altitude before turbosupercharging. Intercoolers and aftercoolers were fitted in addition, to give some idea of the problems associated with this type of engine.

Considering the poor serviceability of the Ta-152C-0 in game (with its LA motor-no intercoolers like the L engine for the production variants had), I can only imagine the kind of troubles which I think should be included into the P.1091 FM for a genuine historical effect.

Can't wait to download the completed version!

Existing some versions of this plane, thi like more a Messerschmitt P.1091a, see this links:

Nice plane. :wink:

Slow, version without under fuselage radiator doesn't have contra rotating propellers.

- vanir - 25.04.2008

That's okay, that'd be the 603U engine version of the P.1091 which was the alternative engine. Mostly climb rate is altered with the extra prop blades and of course with contra-rotating ones you'd get wonderful stability. Still Supermarine toyed with it for their Mark XXI/XXII series, fitting some on Mark XXII's and found them great gun platforms but switched to the five-blade for ease. No real performance is lost, they just make these ultra-fighters a bit easier to fly.

A wide-chord four blade would be the must have replacement to have made service, to maintain similar climb and altitude performance. Other than that you'd see the same results on paper for the 603U/single prop and the 632 twin unit (but pilots might not like you as much). Needless to say autopilots would be standard equipment as per Ta-152 series.

The bonus is the 603U would be much more hassle free to service and maintain in the field, and even better used only B4 fuel.

Just messin' around a bi', not a real mod yet... Well, it would be a good start.

- vanir - 02.05.2008

Oh yeah I see where you're coming from, do a Fw-190/802 instead eh? Just as good, maybe better. Probably an easier engine to have developed into immediate production. Do both. Do us a million warbirds... 8) Sure you may not have a life but we'll love you Big Grin

We will need something of this order eventually, not for quite some time but eventually, when all the post war Spits, Sea Furies, P-51H, F4U-5 and whatnot start appearing.

That's the reason there will be no more mods in the next week (and after that maybe a small time): going on vacation and then there'll be quite a busy school time.

Oh mate, the rate of mods to me seem to come at a lightning pace as it is, take your time, enjoy your life! 8)

S!


Who hoooooooooooo Fw 190/802 gogogogogogogo ....... Slow Akbar!!!!!


Die Vanir and alie planes !!!!



Fantastic 190!!!!
