INTERNAL BALLISTICS OF WEAPON LA UNCHING SYSTEMS
Naval Engineers Journal, 1983ABSTRACTThe management of hot rocket exhaust has been of particular concern in the development of the new canister type launching systems. Special materials have been required to protect the launchers and ships from the rocket exhaust. The design of the Vertical Launching System (VLS) for STANDARD missile has been particularly critical due to the ...

Numerical model for hybrid rocket internal ballistic
49th AIAA/ASME/SAE/ASEE Joint Propulsion Conference, 2013In order to predict the propulsion characteristic of an hybrid rocket, the knowledge of its internal ballistic is essential. The purpose of this work is to write a numerical code, in FORTRAN environment, in order to predict and analyze the propulsion characteristics of the rocket itself. The thermo-fluid dynamics is performed using a zero-dimension non

Internal ballistics of the sling
American Journal of PhysicsThe venerable sling is a difficult weapon to master—we show that very precise timing is required to hit a target. Internal ballistics are analyzed to support ancient claims of the weapon's range (exceeding 400 m in some cases). Many simplifying approximations are used to model the complicated internal trajectory of the sling bullet; they yield a useful

On internal ballistics of liquid fuel rockets
Applied Scientific Research, 1958In this communication the author has given a theoretical treatment for the internal ballistics of a liquid fuel rocket, taking into account the variation of droplet size distribution with time during combustion. A steady state solution, independent of droplet size distribution and rate of evaporation, has been obtained.

Internal Displacements in Cement during Ballistic Impact
AIP Conference Proceedings, 2004The technique of Digital Speckle Radiography (DSR) has been shown to be widely applicable to the field of ballistics through its ability to measure internal displacement fields to a high precision. In a DSR experiment, a flat plane, typically 500 μm thick, of X‐ray opaque filings are introduced into the sample during manufacture.

The internal ballistics of a leaking gun
Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1947The equations of internal ballistics are developed for a gun in which the propellant gases can escape by a vent, whose area can be, in the most general case, a function of time or travel. The most important special cases are treated in detail. The theory has been applied to the testing and design of recoilless guns, to the leakage past the projectile ...

The Internal Ballistics of an Air Gun
The Physics Teacher, 2011The internal ballistics of a firearm or artillery piece considers the pellet, bullet, or shell motion while it is still inside the barrel. In general, deriving the muzzle speed of a gunpowder firearm from first principles is difficult because powder combustion is fast and it very rapidly raises the temperature of gas (generated by gunpowder ...

Internal ballistics of a pneumatic potato cannon
European Journal of Physics, 2009Basic laws of thermodynamics and mechanics are used to analyse an air gun. Such devices are often employed in outdoor physics demonstrations to launch potatoes using compressed gas that is here assumed to expand reversibly and adiabatically. Reasonable agreement is found with reported muzzle speeds for such homebuilt cannons.
