New IL-2 update shows off P-47D-22, details new damage model

IL-2: Great Battle Series’ damage model is still the industry leading system in my opinion with damage model and effects that surpass other sims (although ED’s upcoming DCS: WWII assets are about to make a major leap themselves). That doesn’t mean that the system is perfect and this week’s dev update details a lot of those changes. We also get a great look at the new P-47D-22 for Battle of Normandy!

Normandy Razorback

It’s our first work in progress Battle of Normandy content and it is the P-47D-22 Thunderbolt with the older style ‘Razorback’ configuration. This was the typical configuration of P-47 models until the D-25 and invariably the D-28 that we have in IL-2: Battle of Bodenplatte.

Reduced rear visibility and more canopy framing will make target acquisition a bit harder, however, the D-28’s performance is somewhat hampered by it’s turn to the job of fighter-bomber. The bubble canopy did reduce performance slightly so this P-47 should be a bit faster and better handling – it still has the paddle blade propellers so climb rate remains higher.

Damage model overhaul

The big part of this week’s update was AnPetrovich’s detailed explanation of what they have done to overhaul the damage model. They have updated all 59 aircraft in the simulation with the new damage model along with vehicles including the detailed tanks in Tank Crew.

The new model uses aircraft component blueprints and technical documentation. I’ll let AnPetrovich take it from here.

The main news is that our new damage model now uses data taken from blueprints and technical documentation. Such as: the number of structural elements of one or another part of the airframe, their material and geometric dimensions. An engineer who sets up the DM no longer needs to invent anything and rely on dubious empirical data. Now everything is extremely concrete and objective: what figures from documents you put in the model, such resistance to combat damage you get. Our engineering team carefully collected all this data for all 59 aircraft in the simulator. This is a lot of work, and it took a lot of effort and time. But the result was worth it: now all the planes in the Great Battles have such a balance of vulnerability that they, with a very high probability, had in real life.

Not changing are the visual representations although it is indicated that this should make those visuals match up a little better with the damage being done. Also not yet changing is the engine damage model system which sounds like it may see its own overhaul.

This should have a huge benefit to the damage model on the whole although it will require a bit of retraining ourselves to expect damage on different aircraft in different situations.

There’s much more to his explanation on how they are working this including how HE and AP damage types are calculated and more in the developer diary. Worth reading if you want to understand both the research levels required to achieve this and gain a deeper understanding of how they do these changes to the sim. Read that developer diary if you want more!

    I waited for that DD and it’s just great. In general i think that the simulator will really benefit from it, like from the new pilot physiology. Even the first few steps for the engine damage model make me happy, even when i would love to see a complete overhaul aswell, since our though radials should feel a little bit more thougher.
    And as it looks like we probably see the update in the next few weeks, what really hypes me 😀 Not even talking about our lovely earlier Jug here, which will be a sweet addition to its later sister.

    I love that today’s software is in a constant state of evolution, simulators have a considerably longer life span than ever before because of this. Back in the day the devs would release a patch or two and then move on to the next project.

    Man does that Razorback look fabulous!

    Look at that jug it’s amazing. Also drooling over the DC’s p47. I do prefer their flight models and feel of flight
