Aircraft Damage Model Improvements
11. All aircraft got the new, significantly more advanced version of the airframe damage calculations: each aircraft has its own geometrical sizes of the airframe parts and the material types while the damage calculations take into account the peculiarities of the AP, blast and fragmentation damage;
12. A complete rework of aircraft skin damage calculations has been done and it now takes into account the projectile caliber or its HE capability: now AP ammo and bullets damage the aircraft skin to much lesser extent than HE ammo while ramming an aircraft with a propeller of another instantly causes severe aircraft skin damage;
13. Visual hit effects (sparks, splinters, etc.) and sound effects now depend on the material of a hit part of the aircraft;
14. A one projectile impact won’t erroneously cause multiple (doubling) damage effects on the airframe parts which have several hitboxes;
15. Projectile impacts (and ramming an aircraft with a propeller of another) at the parts which don’t have their own cracks modeled in 3D visual model (for instance, when shooting at a wing root that should cause a crack in the wing on the aircraft where a crack at the wing base is not modeled) are calculated in more detail;
16. Projectile impacts (and ramming an aircraft with a propeller of another) at the parts not connected to the airframe won’t damage the airframe (for example, hitting an engine nacelle of a twin-engine aircraft won’t destroy a wing);
17. The calculations of the energy impulse transfer to an aircraft from a munition it was hit by now take into account the shots that went through it;
18. Exploding shells no longer damage the airframe by their initial kinetic energy of an intact shell, only by the blast and the kinetic energy of its fragments;
19. The following visual effects of the aircraft fragments were corrected (turned on when needed and off when not needed): landing gear dust (in the flight), the lighting from landing and navigation lights, guns firing and engine exhausts, smoke from smoke generators and vortex trails from the wingtips);
20. The found discrepancies between a new and repaired aircraft aerodynamics have been fixed;
21. A rare issue that could cause the airframe cracks to preserve after repairing has been found and fixed;
22. The modeling of the combat damage of the piston engine crank gear became more detailed and takes into account the engine type (for instance, the damage of the crank gear of the air-cooled engines happens more rarely than crank gear of the liquid-cooled engines) and the peculiarities of the armor penetration, blast and fragmentation effects of the munitions. The damage of the crank gear can cause the wedging up and seizing up of the crankshaft while the heavy momentary incurred damage can cause the immediate stop of the crankshaft;
23. It is now possible to damage one or several engine cylinders at once by weapons fire, reducing its power output. Damaged pistons can affect the crank gear and can be accompanied by oil and coolant leaks. The calculations of the incurred damage and leakage values take into account the type of the engine and the peculiarities of the armor penetration, blast and fragmentation effects of the munitions;
24. The calculations of an engine fire probability from torn fuel lines and oil leaks take into account the peculiarities of the armor penetration, blast and fragmentation effects of the munitions;
25. The physical model of the engine now differentiates the two types of oil leaks: from the engine and from the oil system;
26. Only the actual oil leak from the engine now soils up the canopy instead of a general engine damage;
27. An excessive amount of piston engine shaking caused by the crank gear damage has been reduced;
28. The calculations of an oil tank or oil radiator leak probability, its size and leakage value take into account the peculiarities of the armor penetration and fragmentation effects of the munitions in detail;
29. The calculations of a coolant tank or water radiator leak probability, its size and leakage value take into account the peculiarities of the armor penetration and fragmentation effects of the munitions in detail;
30. The calculations of a fuel tank leak probability, its size and leakage value take into account the peculiarities of the armor penetration and fragmentation effects of the munitions in detail. The fuel tanks leak protection will be taken into account later, when the next level fuel system modeling is finished;
31. The visual intensity of a fuel, oil, and coolant leaks now corresponds to the actual severity of a leak closer;
32. When calculating the probabilities of a fuel tank fire and explosion, the different AP, blast and fragments effects are taken into account as well as the amount of the fuel leaking from the tank at the moment. Inert-gas pressurization and other fire countermeasures will be taken into account later when the next level fuel system modeling is finished;
