I noticed something. Those more recent IFV designs (Puma, CV90, K-21, etc) share a common feature: the front side has a flatter but lengthier slope shape than Bradley. Is it a coincidence or some kind of protection enhancement?
yeah i don't think it has a thing to do with amphibious features as both vehicles like Sebastian said are not .... sloped and angled armor does provide natural protection....long story short? i just don't know.
Maybe they're not amphibious in the true sense of the word, but they still need to cross water.
Other guess would be that someone decided that the lower glacius is more likely to be hidden behind berms and whatnot. So more angling on the top glacius would better protect the part that's still exposed.
Puma has got be the best damn awesome looking IFV. German engineering @ her best. I wish US Army brought those beauties for our troops. BTW, what’s utility of that honeycomb pattern case wrapping around the gun barrel (besides protecting the gun barrel)? I have seen this feature becoming more prominent on some of latest combat vehicles.
i think, don't hold me to this, that it has to do with barrel droop. supposedly it suffered pretty badly from it. why they chose that route instead of simply a thicker barrel is beyond me but hey, it works.
The barrel support was added later on as the base gun failed some accuracy tests (hot barrel testing) barrel was a bit skinny to support the added bulk of that velocity meter on the muzzle,frame is light weight sheet metal and adds way more rigidity for less weight than thicker barrel would.
We have to take in consideration that puma uses a 30mm instead of 40mm gun due to keeping the weight to air transportable limits.
The wrapping around the barrel is a damper to avoid big oscillations. Even the rate of fire was reduced for the cannon from 800 rounds per minute to 200 rounds per minute to get a better accuracy.
Puma and nev gen IFVs are longer (cca 3 foot) than bradley in part due to having almost twice the power so a bit more lenght for powerpack equals flater glacis.
the Puma has a compact high performance engine. its actually smaller yet more powerful than the Bradley version. the length of the vehicle has nothing to do with the powerpack.
Probably is related with the capacity to "surf" the dunes. Watch this video of the Otokar and how that slope at the front allows to not get stuck when they go down at the end of the slope.

ReplyDeleteMy guess is that they do that to improve amphibious performance.
DeletePuma & CV90 amphibious? No...

The last time a Bundeswher Cross was seen on a Tracked Vehicle thundering across sand dunes, Rommel and Montgomery were playing Chess in North Africa.
