Brandgranatpatrone mistaken

Ok third and last report for today. :smilewink:

 

So I noticed the weapons.lua says the Brandgranatpatrone is modeled, but it actually is a different one which is called the Minen- Brandgranatpatrone. Between 1943 and mid 1944 several new types of 30mm ammo were designed and produced. The June 1944 loadout recommendation (LDv 4000/10) for the MK 108 is as correctly scripted in DCS 1x Minen-Geschosspatrone and 1x Brandgranatpatrone. (Dont mind the Gl. Spur and L.Spur, its irrelevant. Gl.Spur is for Nightfighters and Brandgranatpatrone doesnt have L.Spur.) The other possibility is to only load M- Brandgranatpatrone, which is pretty much a mix of the both types.

The culprit is actually that the Brandgranatpatrone is not modeled, but instead the Minen- Brandgranatpatrone. Following are pictures of the two. Now there is also a difference in mass between M-Geschosspatrone/ Brandgranatpatrone (~330g) and M- Brandgranatpatrone (~370g) with the corresponding ballistic differences.

The following ballistic tables correspond to M-Geschosspatrone/ Brandgranatpatrone (~330g) and M- Brandgranatpatrone (~370g) which is actually mislabeled there as well. Maybe thats were the mistake originally came from? But as you can see in the technical drawings above the M-Geschosspatrone & Brandgranatpatrone both have the same mass of ~330g.

The ballistic tables are from Handbuch der Flugzeugbordwaffenmunition 1936-1945. The colored drawings are taken from LDv 4000/10. (de.scribd.com/doc/214886494/L-Dv-4000-10-Munitionsvorschrift-fur-Fliegerbordwaffen-Teil-10-1944)

 

The weight of the MK 108 cartridge is pretty much spot on.

The beltpieces were actually 5g lighter than DCS puts them in the weapons.lua. 105g instead of 110g.

So to conclude, as loadout either only M-Brandgranatpatrone should be used or the (more frequently used) M-Geschosspatrone/ Brandgranatpatrone combination. For the latter version the Brandgranatpatrone needs to be modeled. As shown above in terms of ballistics it is the same as the M-Geschosspatrone. Also the belt pieces are a tad to heavy. Thanks for reading!

Has anybody of ED looked into this?

nly

Yes, but we need to perform some research on the matter. We have ballistics ready for all known 30 mm ammo, and the only problem is what types will be available.
