Wing-cannon recoil in General Discussion Posted February 10 4 hours ago, LLv34_Flanker said: S! The recoil of a gun is high. For example the recoil of Gsh-23-2 23mm gun on is 3500kg. Installed on Mig-21 etc. The recoil of the 45mm gun on Yak-9K was enough to throw off thec aim after 2-3 shots and also did cause structural problems. The 37mm guns on the IL-2 were not a success either, recoil causing yaw. Finns called the P38 the rocking chair due its 37mm gun rocking the plane etc. So is CloD modelling that much off after all? It is I would say it's exaggerated to say the least. I feel like you would have extra vibration added more than yourself actually being rocked around by the action of the weapons. The structural problems were mainly caused by poor mounting of the weapon in an airframe it wasn't designed for. Not really the same thing as let's say a bf109e4 with wing cannons that were designed to be there.
