N2 - The interior ballistics simulations in the single-stage gun and the AGARD gun are carried out, using solid/gas two-phase fluid dynamics code of two-dimensional axisymmetric calculation by: 6. Few defense companies can claim a pedigree as distinguished as that of General Dynamics Ordnance and Tactical Systems. Quality propellants have been supplied to the armed forces of the United States and its allies since We continue the legacy as a U.S. leader in propellant technology, currently offering over types of propellants.

    Liquid propellant or liquid explosive such as Nitroglycerine and Dinitrotoluene are added to NC. - produce lower flame temperatures which reduce gun barrel erosion. Composite Propellants - Fuel and oxidizer are separate materials - Fuel acts as a fuel and binder - Can be extruded, injected, or melted and poured directly in a rocket motor. Modern propellant type well stimulation devices were developed around 40 years ago. Since that time, dozens of patents have been issued for different flavors of gun propellant / rocket fuel / low explosive well stimulation schemes; we have a stack around a foot tall.

    experimentation by the exercise of predictive methodologies. This new approach to gun propellant formulation is outlined in a parallel report [2] that describes a science-based activity where the earliest possible steps utilize modeling and simulation of all stages that might occur during development of a gun propellant. To attain a useful density for storage, most propellants are either solid or liquid. Ballistics and pyrotechnics [ edit ] In ballistics and pyrotechnics, a propellant is a generic name for chemicals used for propelling projectiles from guns and other firearms.

Using a lumped parameter approach, a set of simultaneous differential equations was derived for the complex interaction of the propellant fluid, the driving injector and the : Craig Richard Dampier.

The propellant feed system of a liquid rocket engine determines how the propellants are delivered from the tanks to the thrust chamber. They are generally classified as either pressure fed or pump fed.

The pressure-fed system is simple and relies on tank pressures to feed the propellants. Dynamic Simulation and Parametric Study of a Liquid Propellant Engine Application of a simulation algorithm to a specific liquid propellant engine with experimental verification Aircraft Engineering and Aerospace Technology, Vol.

78, No. 2Cited by: The main objective of the book is to describe, in depth, the results of various experimental and theoretical research from until the lates in the field of liquid propellant propulsion.

Even today, most of the information concerning liquid propellant gun research. A series of the simulations by changing the mass of projectile and propellant clarifies that the launch system requires the heavier projectile for ensuring the sufficient time of the projectile.

Liquid Propellant Gun Technology is the first book to provide a comprehensive and systematic up-to-date treatment of this technology.

The book discusses early approaches to gun design, such as bulk-loaded configurations and the use of regeneratively injected bipropellents, through very recent developments in the field of large-caliber and electrothermal-chemical systems. Propellants. The materials used in liquid propellant systems must be compatible with the type of liquid propellant used.

The type of fluids used in launch vehicles and spacecraft liquid propellant systems can vary widely from inert gases to highly hazardous hypergolic fluids. The propellant feed system of a liquid rocket engine determines how the propellants are delivered from the tanks to the thrust chamber.

They are generally classified as either pressure fed or pump.

Liquid-Propellant Rocket Combustion Instability Mod Lec Feed Systems for Liquid Propellant Rockets. Similar to the gas gun, the propellant gun consists of the breech, barrel, target chamber, and catcher system (Fig.

The only difference is that in propellant gun the propulsion of the projectile is done by a propellant. The projectile is attached to the nose of the cartridge filled with double-based solid propellant. The propellant feed system of a liquid rocket engine determines how the propellants are delivered from the tanks to the thrust chamber.

They are generally classified as either pressure fed or pump fed. The pressure‐fed system is simple and relies on tank pressures to feed the propellants into the thrust by: 2.

Combustion Products of Propellants and Ammunition midgets did not feel too happy in the confines of their tank turret and driver’s compartment.

Bad ventila-tion in the cramped interior caused fatigue and ex-haustion, reducing combat efficiency and endurance. In fact, Arab tank crews, overcome by File Size: KB. The interior ballistics simulations in 9 mm small gun chamber were conducted by implementing the process into the mixture multiphase model of Fluent V platform.

The pressure of the combustion chamber, the velocity, and the travel of the projectile were investigated. The performance of the process, namely, the maximum pressure, the muzzle velocity, and the duration of the process was by: 1.

propellant feed systems than what has been acceptable in the past. It is the purpose of this paper to provide an assessment of particular leak detection methods and techniques for high-pressure gaseous hydrogen and liquid oxygen propellant feed systems based upon lessons learned from LASRE.

In addition, the paper provides. The pneumatic (pressurizing gas) and hydraulic (propellant) flows in a liquid propellant engine can be simulated in a computer analysis that provides for a flow and pressure balance in the oxidizer and the fuel flow paths through the system.

Other than being mechanically complex - as either a mono or binary propellant must be pumped into the chamber at each firing - with admittedly minimal research I've not found why no such gun.

The US Army did some work on liquid propellants for tank and SP guns. The main advantage in an armored vehicle was that you only had to rack and load the shell; the propellant would be injected into the chamber from remote storage in well protected tanks that could make use of odd shaped spaces that would not accomodate fixed rounds.
