Abstract:
Blast waves generated from the muzzles of weapons may exert negative effects, such as shock waves and impulse noise. If the weapon is fired with a muzzle brake, these effects are recognized to be more severe. This paper discusses the influence of the muzzle brake on certain aeroacoustic noise characteristics based on numerical simulations and a corresponding experiment. The impulse noise, which is induced by complex jet flows discharging from small caliber rifles with muzzle brakes, is focused in this study. Computational fluid dynamics (CFD) and computational aeroacoustics (CAA) are combined to calculate the muzzle flow field and jet noise for cases with and without a muzzle brake, and then the data sets are carefully compared. The simulations indicate that the muzzle brake alters the muzzle flow field and directional distribution of the jet noise compared to a rifle sans muzzle brake. Deviations less than 7.6% between experimental data and simulation results validate the simulation model. The results presented in this paper may provide a workable reference for the prediction of muzzle noise and the optimization of muzzle brake designs.

Abstract:
The approximate model of the muzzle brake performance was set up and evaluated to simplify the analysis process. LHS(Latin Hypercube Sampling) and numerical simulation of inviscid muzzle flow field were applied to obtain some samples of the muzzle brake performance. The performance was weighted with the impact force on the muzzle brake. Then RSM(Response Surface Method) was adopted to get the approximate model of the muzzle brake performance to establish a mapping of muzzle brake shape parameters and the impact force. In the end GA(Genetic Algorithm) was applied to perform the optimization of the muzzle brake shape parameters with the approximate model.

Abstract:
The development of advanced artillery needs to be combined with simulation means, so, traditional calculation method and the flow field simulation method was employed to calculate the efficiency of a largecaliber muzzle brake we designed, and the results achieved by these two methods were 47.8% and 49.3%, respectively. Further, the overpressure value 1 m away from the muzzle was obtained through flow field simulation, and the far-field overpressure value was calculated using blast wave attenuation equations. The result suggests that the blast wave from the designed muzzle brake has little harmful impact. This paper provides an intuitive calculation method of muzzle brake efficiency, also, it provides theoretical support for research of high efficiency muzzle brake and personnel protection onboard.

Abstract:
In order to reduce the recoil energy of the chain gun, this paper put forward a high-efficiency recoil-reducing way with new-style high-efficiency muzzle brake and buffer parameter combined by studying the modeling and simulation of low recoil firing of chain gun. This paper studied the variation rules of gun recoil movement and recoil force of muzzle brake on three states. The results show the recoil of chain gun can be reduced significantly by using high-efficiency muzzle brake and selecting suitable parameters for buffer compared with that of only using muzzle brake and buffer. The research results put forward theoretical basis and application reference for studying high power low recoil chain gun.

Abstract:
Gunpowder was released in an instant when the pill fly out of the shell during the firing, and then formed a complicated flow fields about the muzzle when the gas expanded sharply. Using the 2 d axisymmetric Navier-Stokes equation combined with single equation turbulent model to conduct the numerical simulation of the process of gunpowder gass evacuating out of the shell without muzzle regardless of the pill’s movement. The numerical simulation result was identical with the experimental. Then simulated the evacuating process of gunpowder gass of an artillery with muzzle brake. The result showed complicated wave structure of the flow fields with the muzzle brake and analysed the influence of muzzle brake to the gass flow field distribution.

Abstract:
This paper discusses characteristics of supersonic projectile shock wave in muzzle regions when firing high explosive anti-tank (HEAT) and high explosive (HE) projectiles. They are fired with a muzzle velocity of Mach 3.5 at horizontal from a medium caliber tank gun equipped with a new designed multi-perforated muzzle brake and of Mach 2 at elevation angles from a large caliber howitzer also equipped with a new double baffles muzzle brake, respectively. In the near field, pressure signatures of the N-wave generated from projectiles are measured by cotton sheathed 32-microphone ring array. Recordings measured from the microphone array are used to demonstrate several key characteristics of the shock wave of supersonic projectile. All measurements in this study can be a significant reference for developing guns, tanks or the chassis of fighting vehicles.

Abstract:
A modern tank gun for light vehicles should be light in weight and have a low recoil force. Therefore it needs an integrated muzzle brake that, however, reduces the strength in the muzzle area. The loading due to gas pressure in this area is as fast as the projectile, and some dynamical effects like traveling waves have to be taken into account. The analytical solution of traveling waves for a smooth tube will be explained on the basis of the shell theory for thin shells. The solution leads to a deeper understanding of the nature of these waves than a pure numerical solution. Since tubes are not really thin, even in the muzzle area, the error that may occur when applying the shell theory is estimated. The analytical solution will be compared to some finite element solutions, which include a multiperforated muzzle brake with a cover tube. The results give some useful hints to the interaction between gas pressure, projectile velocity, and wall thickness and help to reduce the weight of the barrel.

Abstract:
Muzzle brakes (MBs) have a great effect on reducing the recoil force of weapons during firing. In this paper, optimum MB efficiency, MB force and recoil force for (12,7 x 99 mm) sniper rifle have been studied. The objective is to obtain the optimum area of side openings, inclination angle and number of chambers for the MB in order to increase the MB efficiency and MB force and thereby to decrease their coil force of the weapon. An analytical model for calculating MB efficiency, MB force and weapon recoil force for MBs of two, three and four chambers has been established. This Model is then utilised in combination with design of experiment (DOE) and Response Surface Method (RSM) statistical techniques to develop a smooth response function which can be efficiently used in optimisation formulation. Finally, multi objectives generic algorithm (MOGA) optimisation method has been employed to find the optimum MB design parameters. The optimisation results show that the three or four chambers MBs have no significant effect on reducing the weapon recoil force compared with the two chamber MB for this sniper rifle.

Abstract:
A conventional muzzle brake is a baffle device located at some distance in front of the muzzle exit of a gun. The purpose of a muzzle brake is to alleviate the force on the weapon platform by diverting a portion of the muzzle gas resulting in a forward impulse being exerted on the recoiling parts of the weapon. A very efficient muzzle brake unfortunately gives rise to an excessive overpressure in the crew environment due to the deflection of the emerging shock waves. The novel active muzzle brake of this dissertation is based on a concept developed by Qinetiq. The novel technique involves the main brake chamber being closed for a very short period of time after the projectile has uncorked from the barrel eliminating the main emerging shock wave from developing to full strength with the result that the novel muzzle brake gives rise to a very low overpressure. This has the advantage that the gun crew suffers from less strain to the ears and vulnerable organs. Inherently the novel brake suffers a loss in efficiency due to the chamber being closed for a while and a method had to be developed to improve the efficiency of the conventional part. This dissertation deals with the development of a novel active muzzle brake intended for a 155 mm artillery weapon, but scaled to an 88 mm 25 pounder G 1 as an interim phase. Several constraints and requirements have been set regarding the physical properties and performance criteria of the prototypes. The interim phase of the project was executed within three years in which six prototypes were developed and evaluated. Major challenges in the development were to design a control and restoring mechanism that would survive the harsh conditions at muzzle exit and to enhance the efficiency. The establishment of linear movement of the closure mechanism and friction springs as the restoring mechanism was a major breakthrough in this respect. The first four prototypes were designed using empirical data and first order modeling as background while a CFD technique was used to refine the last two prototypes. Of the six prototypes developed, the first two were unsuccessful in demonstrating the novel technique. The one was unable to survive the muzzle exit conditions and the control mechanism on the second muzzle brake opened too soon. Of the remaining four, the last prototype passed all the specified constraints and proved to be a candidate for the 155mm upgrade. Not only was the structure robust enough, the general appearance of the novel muzzle brake is futuristic. This prototype is also a candidate if a much more efficient muzzle brake, with similar overpressure characteristics of a less efficient muzzle brake, is needed.

Muzzle brake is an important facility which mounted on the cannon. It's used to absorb a portion of the recoil impulse by deflecting a portion of the propellant gases, and also, increases the range, stability and accuracy to meet the desired operational functions. The gases discharged from a gun muzzle after firing determine the strength of the blast, which affects firing crew, equipment and shell accuracy. As mensioned in many publiced papers, the muzzle blast flowfield is complex and inherently unsteady, and mostly investigated experimentally through the firing test. However, these experiments are usually difficult, expensive and, sometimes dangerous. Thus, a numerical model of the near field flow environment can be used to reduce the development and testing costs , and also provides detailed information needed for proper structral design, including determination of the overpressure environment. A three-dimensional numerical inviscid model of the time-dependent near field of multi-block muzzle brake has been developed in this theris. The model includes the effect of the free air blast, the exhaust of the barrel air ahead of the shell , shell ejection and flight, the exausting of the propellant gases, and the recoil influence of muzzle brake. The TVD upwind method for solving the Euler Equations has been developed to simulate these complex problems. For the spatial discretization, the least artificial viscous Roe's solver with high order Kappa MUSCL interpolation was used and, the second order explicit Hancock method was employed for time integration. Finally, a computer code was established for the computation of this unsteady flowfield with the moving projectile. The code shall be validated wherever the experiment data are available. With the results of the computation, the effects of different muzzle brake designs can be further investigated.

Two main types of muzzle brakes named baffle type and light weight type have been designed for carrying out the simulation and analysis of muzzle flow in this research. The utilizing of parameters from simulations and some given conditions to impact deflectors of muzzle brakes to make the recoil part get a momentum to move forward in order to lower recoil force have been expressed in this research as well. Via performing flow field simulation, stress analysis and modal analysis of single baffle, double-baffle and triple-baffle muzzle brakes, safety factors were 2.5, 2.1 and 4.8 respectively, nature frequencies were 12.08Hz, 11.64Hz and 9.95Hz respectively, and muzzle efficiencies were 31.5%, 38.6% and 33.7% respectively. The light weight muzzle brake owns a high efficiency to 39.4%, in the same time it owns benefit by light weight and easy manufacture. Through the using of topology theory, the lower stress area could be removed about 70% volume and shorten assembly time to reach the goal of DFA.
