Research on Mathematical Modeling of Naval Gun Servo System

Abstract Tracking performance of naval gun servo system is very important to the whole combat function of naval gun weapon system. Therefore, it is very important to construct accurate mathematical model to improve the performance of servo system. This paper analyzed the structure of naval gun servo system in detail and established the transfer function of each component according to its working principle. Finally, the complete mathematical model of naval gun servo system is established through the organic combination of all parts. Then the stability of the mathematical model of naval gun servo system is judged by Rouse criterion. When the original servo system is unstable, it is necessary to modify the model of servo system by designing lead-lag correction to achieve stable control of the servo system, which lays a foundation for further research on control performance optimization based on mathematical model of naval gun servo system.

Research on Inferring ELECTRE-III’s Parameters with Fuzzy information and A Case on Naval Gun Weapon System Integration

Multiple attributes decision making (MADM) method is an important measure for system integration. Robustness analysis on MADM is a hotspot in these years which wins academe’s great attention, and is supposed to be an effective way when countering imperfect information.

Electromagnetic gun/projectile interface considerations

Projectile/electromagnetic-gun interface design considerations for electromagnetic gun weapon system (EMGWS) area D1 projectiles, area B-guns, and area C-guns are presented. Projectile/EM gun interfaces are primary considerations in the projectile structural design and the design of the sabot obturator/bore rider, pusher plate, and armature. Acceleration profile, armature type and mass, preinjector characteristics, bore pressure, magnetic fields, and plasma temperature are all key issues in the ultimate projectile performance. Armature design is a critical technical issue for both the projectile and EM gun design because of the high masses involved. Solid armatures are heavier than plasma armatures, but operate at higher electrical efficiencies. Plasma armatures are both being considered for the B-guns and C-guns. Performance tradeoffs are presented for penetration versus peak acceleration and armature mass. Contributors to projectile dispersion such as in-bore balloting, projectile spin, and EM launcher muzzle arc effects are assessed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

THE IMPROVED 16‐INCH GUN WEAPON SYSTEM

ABSTRACTThe Iowa class battleships are being returned to active service without significant modifications to their 16‐inch Gun Weapon System (GWS). The ordnance, 16‐in. guns and associated fire control equipment are currently 1940's vintage technology. The reactivation was accomplished without significant modernization to the gun systems due primarily to funding limitations. In the late 1970s naval gunfire had fallen out of vogue and no pressing need for 16‐in. GWS improvements existed.With the development and subsequent deployment of the landing craft air cushion (LCAC) and the MV‐22A Osprey, naval surface fire support (NSFS) of Marine amphibious operations was reexamined. Specifically, the means of generating supporting fire from surface combatants required extensive analysis. The resulting analysis indicated that the most cost‐effective partial solution to the problem was an extensive modernization of the battleship's 16‐in./50 GWS. With such a modernization, the range, lethality, and response time of the weapon would be significantly improved.Except for the gun turrets themselves, the 16‐in. GWS will be almost completely modernized. Extensive modification of the ordnance and fire control system will be accomplished.This paper first discusses the reasons for the improvement in the 16‐in. GWS. It describes, in detail, the new 16‐in. ordnance under development, highlighting the operational issues which drive the engineering approach. Finally, the new gun fire control system (FCS) is described. The advantages of streamlining with digital equipment are highlighted. Some unique features of the FCS, which are appropriate in its operational environment, are discussed.
