Possible to get current list of updates flight/engine models?

[Voyager]

With the introduction of compressibility and extreme high altitude flight, most of the aircraft are needing the effects added to their flight models. I'm wondering, is there a working list somewhere of which planes have compressibility and high altitude engines modelled, which ones are in work, and which ones are yet to come?

[Psyrion]

The compressibility added in 3.007 was for all aircraft at the same time.

Speaking of which, could anyone help explain in general terms how the plane behavior changed after the addition of these ‘compressibility effects’? Did all planes become more heavy on the controls at speed? At both low and high alt?

My understanding is, the planes should have a critical mach number, past which their controls lose responsiveness and their center of lift shifts aftward. Different planes will have different critical mach numbers, and likely different CoL shifts. 

 

Also, your speed in mach is based on the outside temperature and your true airspeed, not indicated airspeed, so the higher and colder you get, the higher mach you are at for a given indicated airspeed. 

 

Some of the values I've seen indicate that a number of the late war high performance props could get into compressibility effects in level flight at altitude (P-47M at 30kft could do >350 mph indicated, while the manual restricted dives to less than 318 mph indicated at that altitude) 

 

It does occur to me that I haven't done many dives in plane another than the P-47, so was assuming that not all of the planes had their mach behavior finished. 

 

I do recall that they did not all get their high altitude engine behavior at the same time, so thought it was expected that the transonic effects would come in in stages as well, until Bodenplatte is fully released. Have the devs said that all the planes have their effects in yet?

The patch notes for 3.007:
"Our physics engine now includes the aerodynamic effect of air compress-ability at high Mach numbers. [...]  However, all airplanes in the Great Battles series now has this feature."

I was just wondering whether anybody had any real factual evidence of VVS aircraft turning and climbing rather than what is just presented to us and we are expected to believe!

I have just read a book where it mentions that Stalin wanted every aircraft to have a radio and as such it was reported that every aircraft had a radio, as people didn't want to be executed, although this wasn't the case!

Therefore, in this game where I watch VVS aircraft spin and climb and dance over the sky like a ballet dancer, does anybody actually have any factual evidence that they can support the maneuverability of VVS aircraft please,

Out of line and also rule 18,20

Sorry but its also off topic. Rule 15

Honestly it doesn't seem like all aircraft have compressibility modeled to the same degree. 

I'll have to recheck but it seems to me that aircraft like the P-47 lose control response too early while other maintain control for too long.

Basically what I see in-game disagrees with everything I've read for the most part.

 

Also, compressibility doesn't seem to be fully modeled but I'll have to look again.

[Legioneod]

After playing around testing the compressability effects of certain aircraft it's pretty obvious that it's "lightly" modeled. What I mean by that is some of the signs of compressability are barely noticeable in-game.

 

Mach tuck being one of the key signs of compressability is barely noticeable and is too easily overcome imo. Another key feature of high speed flight/dives is aileron reversals, this doesn't seem to be modeled at all in-game.

 

Another problem with high speed dives is the loss of control surfaces. While this was known to happen to some airframes, it wasnt common as it is in-game unless damaged or excessive forces were applied to the structure.

Losing ailerons in a dive was pretty much non existent as far as I've read. The most common point of failure iirc was almost always in the tail surfaces of the aircraft, I know the early fabric tails of the P-47 had this problem.

 

I going to use the P-47 as an example as I don't know what the structural limits of other aircraft were or how common failure was but I'm sure it was similar to the P-47.

The P-47 should NOT lose control surfaces in a dive, simple as that. Once metal control surfaces were installed on the P-47 failure was pretty much eliminated. 

 

I have not found a single account of P-47s losing control surfaces in a dive (after fabric was removed), even up to it's maximum dive speed (around Mach 0.83).

I'm not saying it didn't happen when damaged or excessive load was applied, but in a straight dive with no damage there was almost no chance of losing control surfaces or breaking up in a dive.

 

Herb Fisher did over 100 high speed dives in the P-47 upwards of 600+ mph and in all those dives there was not a single instance of structural failure.

 

What we see in-game is unrealistic and I'm sure the same could be said for aircraft like the 109 and 190.

One unlisted small change to the Yak (all series) engine model I've noticed with recent updates:

 

Yak models now have an 'auto rich' mixture setting of 66% in the techno-chat.  At least this is the clean / no smoke exhaust setting.  The arrow painted on the side of the mixture lever coincides with this.  There's no more running the engine full throttle at 85% mixture and expecting to not leave an exhaust trail.

really？I recently use 80 instead of 85 and that produce clean exhaust below 3000m

Oddly enough, it seems to vary from map to map.  It may have something to do with temperature/weather conditions.  My initial observation was wrong.
