As I am not a native speaker of the English language, I feel a preventive empathy for those who are and read this.
Considering the basic elementary knowledges of the physics and mechanics principes applied to the "confined auto-propulsion inert projectile
" Small Caliber Weapon System, a naive idea come to my mind.
) and intermediate
) ballistics are the two main variables which govern the efficiency of the Terminal
) ballistics. Considering the first two steps, we can put on a methodologic perspective those empirical rules : Velocity
is mainly given by : the relation of powder to barrel lengthInertia
is mainly given by : Weight
The spatial and temporal extension of the quoted properties can be assured by : aerodynamic shape
- A decent barrel length will alow enough time for the speed acquisition,
- A decent weight will assure a good inertia (temporal storage of energy), as the "temporal energy storage used in industry"
- And a very-low drag will reduce to the optimum, the frictional surface offers by the bullet, to limit the kinetic energy destruction by the "air" gas from thermal transfer.
If we apply this to the project of "Unified Small Calibers Ammunition Project
", the limiting factor of the efficiency of USCAP is the upper limit
extension of the range, it mean that if we limit the Small Calibers Weapons System (Assault Rifle, MG, DMR) to decent ranges (0 to 750m), we can "easily" define a "6mm pattern" caliber which will safely satisfy the three criteria, sin equa none ballistics conditions to achieve the "upper limit" exigences range of the USCAP Project. (750m Terminal effects)
As I say, the prototype design and technical solution are already here, some resist to the operationnal exam, some do not : 6mm Creedmoor, 6.5 Creedmoor, 6x49 Experimental, prhps 6 mm SAW..
Only the barrel length will dispatch different prerogatives to the same ballistic, which again, assure by itself at least the two main criteria of energy retention : decent inertia (weight), very low drag design.
Assault rifle : 17 " barrel
MG : 23" barrel
Precision Rifle : 25 " barrel
By the implementation of an Unified Family, all the logistics and bio-mechanics criteria will be easily improved and positively affect on : interoperability, mutual supports, weight, ammo volume, accuracy, recoil for the price of :
- a lower barrel life due to higher pressures and velocities.for a "same terminal effect upper range limit"
Here is my modest, naive and un-scientific contribution to the technical aspects
of the "USCAP" utopia that any infantry man will pursue for his Small Calibers Weapons System.
The decisional and prospective aspects
, so money, so Benefits <==> Costs ratio
, so global incidence of Small Calibers Weapons Systems in Modern Warfares (close to nothing) so, unbalanced Benefits <==> Costs ratio, so waiting for a Technlogic rupture wich will push the Benefits <==> Costs ratio to a strategic point that will destroy any financial barrier..
