  1. Hmm, Ever since the ‘gravity patch’ I often get the technochat message on low injection pressure malfunction, usually after some heavy g pulling. This is usually followed by engine damage at max rating well before exceeding the 10 min limit. I don’t recall having these issues earlier, could be wrong though and it would seem that somehow the g limit would effect/interfere with the MW 50 tanks delivery. Which seems to be odd since it’s not a pump but a pressure feed system.. so how it would effected by gravity forces?
  2. Actually it’s just several layers (about 30) of thin aluminium sheets and it does just about nothing to stop a bullet unless it’s a .303 or similar. It’s not near 30 mm steel armour plate as it would prohibitively heavy. More of scrap aluminium sheets formed into several layers of thick sandwhich and placed as a bulkhead behind the fuel tank. What it did was to slow down the bullets sufficiently so that by the time it got to pilots armor plate (and passing through the fuel tank) they could no longer defeat it. This worked rather well up .50 AP provided the bullet entered beneath the fuel line. More importantly what this dural plate sandwich armor also did was to render incendiaries ineffective and they could not set the fuel tank on fire. Soviet Berezhin API rounds however remained effective so the USAAF actually made straight copies of them later in the war (M8 API iirc).
  3. Clearly there is an issue with the climb rate worth further testing and investigation, yet clearly some would very much like if it would be remain in this state. However apart from the the absolute rates of climb measured, which can be perhaps explained, at least partially with differing test methods, load, and atmospheric conditions, to me it seems that there is a far more serious issue with the altitude range that this climb rate is kept up. That is to say, the in game spit managed to maintain the climb rates that are already suspected to be to high to begin with to far higher altitudes than it was historically capable of. The JL 165 tests indicate the climb rate fell off rapidly from about 11 000 - 11 400 feet, or about 3500 meters. This is logical because that is the maximum altitude the Merlin 66 can maintain 25 lbs boost in climb, as a result, if you went higher, boost and power fell, and so did climb. Though I need some testing to do myself to confirm, testing by others seem to indicate that the in game 25 lbs Spit’s climb not only does not rapidly decrease from 11k feet (up to that altitude it should be pretty impressive) as it should but it even increases / remains the same up to 6000 meters and only then starts to fall back. The center of the issue is the ridiculous climb rate observed above 3500m.
  4. The Merlin 66 could maintain +18 lbs at to about 20-22k feet in fast flight; depending on the particular test plane (FTH varies between individual planes); and to somewhat lower altitudes when in climb (16k iirc) since the airspeed is low and the supercharger is not aided by air pressure from moving through the air fast. However, +25 be maintained to considerably lower pressures only (obviously +18 was maintained to the same altitude as before). It’s obvious because the supercharger was already running at maximum capacity to give +18 lbs pressure; it cannot just conjure out an additional +7 from nowhere, unless the altitude is lowered enough that the supercharger still has that surplus, that would be otherwise throttled down to +18. The FTH is simply far lower for +25 than it is for +18. The real life data clearly indicates that the Merlin 66 in climb conditions could not maintain +25 lbs for more than about 500 (!) feet altitude in MS gear, and about 11500 or so feet in FS (full supercharger speed). It simply cannot give +25 anywhere above that, so boost and power and therefore climb levels begin to decrease if you go higher. The observed issue on the in-game test graph is that it does not seem to work like this. At around 3-3500 meters, the boost should start to decrease and so should climb rate, because power is decreasing. In contrast it seems FS gear just kicks in the game and power and climb is even increasing, all the way up to 6000.
  5. Nobody said its a design flaw and if you can't wrap your head around that, then it's your issue. The Merlin 66 was a low-medium altitude tuned engine, and that's okay. BTW it did not have a cropped blower, that's the Merlin 4xM series. However the issue is that currently it has about twice the full throttle altitude at +25 lbs compared to its real life counterpart, leading to massively inflated climb rates at far higher altitudes than it should possess.
  6. It’s pretty amazing that while the real life Spitfire’s climb rate on + 25 lbs fell rapidly off after ca. 11000 feet, or about 3300 meter altitude (because the Merlin 66 supercharger just could not maintain the boost anymore), our Spit not only does not start to fall off but even increases up to twice that altitude, or up to about 6000 meters.
  7. Right, hence why modern jets still use a very similar seating position. 😄 Actually the data posted there confirms what is already known, that reclined seat position improves G resistance, raised leg position itself appears to add about 0,4 G resistance.
  8. https://books.google.hu/books?id=8OrH2Jg0UcoC&pg=PP46&lpg=PP46&dq=effect+of+reclined+seat+on+g+resistance&source=bl&ots=jMQLLBl9L6&sig=ACfU3U1I6tpyvu89gD3RBnby_144cdH_qw&hl=hu&sa=X&ved=2ahUKEwigvP7okYLlAhULqIsKHcXbBIE4ChDoATABegQICBAB#v=onepage&q=effect of reclined seat on g resistance&f=false Modern G suit is qouted to provide up to 1.6 G tolerance before GLOC F/16 reclined seat design involves a 30 degree reclined seat, qouted to give appx. 1 G tolerance before GLOC From USAF research it is shown that an extreme seat angle of 82 degrees allows to resist up to 15 Gs Interestingly breathing in pure oxygen is believed to aid with G resistance, or perhaps with the time period of exposire, due exta oxygen stored in the cells. I understand pure oxygen was inhaled by respirators at high altitudes, at least that was the case with German breathing devices which gave pure oxygen from about 8000 meter (also it is reported that the breathing in of pure oxygen resulted in great exhaustion after flying).
  9. Steam update download is like 20 minutes.. but it will speed up on the Il2 store once the big initial rush is over. Its a big update.
  10. It’s a feature. Fuselage guns and wing guns were wired together - it was the same setup on the 109 when they were equipped with gondolas.
  11. Indeed, drop tanks and the missing cluster bomb container ordnance is what I miss most from the Western front add on as well. Pursuit types (and their RV opponents) look just odd without their ubiquitous drop tanks and cluster bombs were used very widely by this stage of the war by LW fighters on hit and run Jabo sorties.
  12. Great update! Everything’s great as usual and the Rheinland map looks like one that will be a favorite. However the thing I like the most is the crew of the Flakvierling.
  13. Late G-6 with boost =~ G-14. So basically that’s it, there is not much of a point in it. The only major difference on the G-14 was the Erla canopy, and a minor (non-existing for us, simmers) change in that the MW tank was pressurized with pressure bottles on the G-6 (as the boost was a retrofit), while on the G-14 the pressurized air was tapped from the supercharger.
  14. AFAIK Soviet aircraft with wooden construction, a.k.a. "Stalinwood" , and some sturdier planes (P40?) are modelled with 20% greater resistance to damage. It is mentioned in one of the older update notes.
