The developers of the upcoming combat flight simulator Korea: IL-2 Series at 1C Games released a new video focusing on engine sounds.
The video showcases the two sides of engine sounds during the Korean War, which straddle the era of piston engines and that of jet fighters.
We start with the apex predator of piston fighters, the North American P-51D Mustang, or better, F-51D, as its designation was changed just before the Korean War. Then we get to see and hear the first operational jet fighter the USAF used, the Lockheed F-80C-10 Shooting Star.
For both aircraft, the video features the ignition sequence and a glimpse of flight, highlighting respectively the Packard 1650-7 Merlin and the Allison J33-A-23 engines.
In the accompanying blog post, we read that the sounds are linked to the corresponding processes in the physical model of the engines.
The engine sound system is more detailed compared to previous games by the developer, with changes depending on the direction of the sources. Low-frequency sounds dominate the rear of the jet, while the turbine whistle dominates the front.
There is also a higher variety of sounds from similar objects from newer audio libraries and “reverse-engineered sound synthesis.”

Korea: IL-2 Series is in development for PC, but doesn’t have a release date just yet. Recently, we got to see some interesting animations for the artillery units that will be implemented in the game, the model for the Lavochkin La-11 piston fighter, and a look at the ground vehicles and their destruction.
If you’re unfamiliar with the IL-2 series, it’s a combat flight simulation series that debuted all the way back in 2001 with IL-2 Sturmovik, set on the Eastern Front for World War II.
At that time, it was very innovative among combat flight simulators and provided a lot of interesting features in a genre that was already starting drop out of the AAA field into a much smaller niche. It also included a rather advanced multiplayer suite for the time.
