This article really needs a Shadowgraph or Schlieren photograph of a projectile shortly after leaving the muzzle (for instance, see image (d) at ), or better yet of how a flash suppressor/muzzle brake modifies the shape of the initial shock wave. --Interiot 01:57, 4 May 2007 (UTC)
Who uses this term?
I'm not perfect, however I have NEVER heard of this term nor have I seen it used anywhere in ANY publication among the thousands I've read. Of course, it could be somewhere, but my point is that it is OBSCURE to say the least. Why is there an article with this title? I've heard of internal ballistics, external ballistics, and terminal ballistics, however this term seems contrived. Further, how does the transition from the internal to external differ from case to throat, external to terminal, etc.? Whatever is 'unique and useful' in this article needs to be rolled into internal and external ballistics. --'''I am Asamuel''' (talk) 22:01, 2 April 2008 (UTC)
- Well, the US Military for one; from FM 6-40 Tactics, Techniques, and Procedures for FIELD ARTILLERY MANUAL CANNON GUNNERY: "Ballistics can be broken down into four areas: interior, transitional, exterior, and terminal. It's not commonly used, but it does need to be separated out, as it isn't internal ballistics, because the projectile is out of the barrel, nor is it really external, as the projectile is still being acted upon by the propellant gases and accelerating. It is certainly fairly obscure--a Google search brings up less than 500 hits, with this article being the top--but it is a recognized division of ballistics. The problem is that very little study has been done on the topic. Here's a few sample papers, though, to show that study has been done, and the term is used academically: Near Noise Field of the Transitional Ballistics Phase, The Transitional Ballistics, Aeroballistics and Jump Characteristics of a 25-MM-AP Training Projectile with Base Bleed (which reminds me, need to cover base bleed in external ballistics), Research of Transitional Ballistics Simulation. scot (talk) 14:25, 3 April 2008 (UTC)
