火箭深弹是二战时期出现的、将推进火箭与深水炸弹结合为一体的舰载攻潜武器,它的问世将水面舰艇的攻潜作战距离由上百米扩大至数千米,直到战后较长一段时间内仍是各国海军舰艇广泛装备的反潜武器。20世纪六七十年代,随着具有更大攻潜距离和精确攻击能力的舰载反潜鱼雷以及反潜导弹的发展,美、英等西方国家海军转以自导鱼雷和反潜导弹作为舰载攻潜武器,不再为舰艇配备火箭深弹系统。 相似文献

当九七舰攻的鱼雷砸开太平洋战争的大门之时,日本海军也开始走上不归路。作为中岛公司相当成功的一型舰载鱼雷攻击机,九七式舰攻广泛应用于太平洋各个战区。不过就在九七舰攻原型机刚刚首飞不久的1939年12月,海军航空兵本部就下达了新一代鱼雷攻击机的研制计划,命名为14式(“天山”)舰攻。 相似文献

One of the main challenges associated with anchoring offshore platforms is the logistic needed to install them in deep water. The growing need for high capacity anchors has prompted the development of new systems where the feasibility of transporting them out to sea is a crucial consideration. With respect to torpedo piles used by Petrobras in Brazil, new platforms installed in deep water required robust anchoring systems, and a cluster of small torpedoes was considered instead of one large torpedo. However, torpedo pile installation is hindered by deep water streams, which can deviate their trajectory during the fall. This is of great concern for the design of torpedo pile clusters because the distance between the piles cannot be controlled during installation. The present study aims to determine the variation in the load capacity of a cluster or array of single piles as a function of the distance between the piles and the load direction after installation on the seabed. To that end, a series of centrifuge tests were carried out on pile clusters installed in loose sand, varying the distance between the piles and the loading direction. The results show considerable interactions between the adjacent piles depending on the load direction and pile spacing. The optimal spacing for maximum cluster efficiency was determined, and comparisons were made with values from the literature for capped pile clusters. 相似文献

Torpedo anchors are an innovative and cost-effective technology in marine foundation engineering; however, there is a lack of systematic and comprehensive studies on the influence of torpedo anchor geometry on its hydrodynamic characteristics, especially the effect of anchor fin configuration on the hydrodynamic characteristics is rarely reported in the existing literature. Therefore, this study investigates the influence of geometric characteristics of both finless and finned torpedo anchors on their terminal velocity, drag coefficient and installation directional stability in water through CFD numerical analysis in a systematical manner. The considered geometric characteristics include the center of gravity position, shape and angle of anchor tip, shaft and fin aspect ratio, fin number, fin thickness, fin shape, fin position and fin area. Based on the obtained numerical results, some practical design recommendations and impact weighting charts of different anchor geometric factors are provided, which enables a quick qualitative and quantitative assessment of torpedo anchors. In addition, a simple weight-based approach for estimation of terminal velocity and drag coefficient of torpedo anchors considering multiple geometric configuration factors is proposed, which may provide some reference and scientific guidance for experimental and engineering design of torpedo anchors. 相似文献
