Why the conventional flat bullets are succeeded by Rebated Boattail Base??
Doesnt in the former case a uniform pressure be exerted across a flat base to effectively push the bullet out of muzzle with precise orientation??
you mean software ??Hoof wrote:Looks a bit on the old side... they could have probably used different type stabilizers on it...
but I think Russian planes can use it... as long as mounting system on a hardpoint is compatible... but then equipment on board of aircraft also has to be compatible with guidance system on a bomb itself...
Water injection has been used in both reciprocating and turbine aircraft engines.
When used in a turbine engine, the effects are similar, except that
preventing detonation is not the primary goal. Water is normally
injected either at the compressor inlet or in the diffuser just before
the combustion chambers. Adding water increases the mass being
accelerated out of the engine, increasing thrust, but it also serves to
cool the turbines. Since temperature is normally the limiting factor in
turbine engine performance at low altitudes, the cooling effect allows
the engines to be run at a higher RPM with more fuel injected and more
thrust created without overheating.
The drawback of the system is that injecting water quenches the flame
in the combustion chambers somewhat, as there is no way to cool the
engine parts without cooling the flame accidentally. This leads to
unburned fuel out the exhaust and a characteristic trail of black smoke.
Which launching method you relatively prefer either Hot launch or a cold
launch??Mine understanding is it is cold launch systems that are
heavier, and in the case of mobile launching, more cumbersome.

As I recall the calibre refers to the diameter between the groves in the rifled barrel; not to the diameter of the bullet. The diameter of the bullet, and the diameter of the barrel will be a bit largermilky_candy_sugar wrote:This question has been bugging me since i started cataloging my ammo collection.
Why are some calibers who's dimensions are listed in their name, different from their actual dimensions?
Actual Bullet Diameter is 5.7mm
actual diameter measures 7.8-92mm
diameter measures 8.2-3
these wouldn't bother me so much, if there werent other calibers that actually listed their dimensions correctly.
5.7x28mm for example is (5.72x28.8mm) so thats much closer.
I dont know anything about reloading, so im going to claim ignorance if there is something important that im missing here.
Also, i'm getting most of this information from Wikipedia and my own physical measurements
