The ET52 is a Chinese copy of the Italian Alenia A.244S Whitehead lightweight anti-submarine torpedo, which China obtained in the mid-1980s. ET52是意大利阿莱尼亚(Alenia)公司A.244S“白头”(Whitehead)轻型鱼雷的一个中国仿造型,中国在1980年代中期获得。

China obtained a limited number of Italian Alenia B.515S triple 324mm torpedo launchers and A.244S lightweight anti-submarine torpedoes in 1987. The A.244S torpedo has been produced in China under the designation ET52. The PLA Navy operates the A.244S/ET52 torpedo on some of its Type 051 (Luda class) destroyers and the Harbin Z-9C shipborne helicopter. The torpedo is also available for export market.

PROGRAMME

The PLA Navy purchased some B.515S triple 324mm torpedo launchers from Italian defence technology Company Alenia in 1987 to be fitted on its Type 051 Luda class missile destroyers. Along with these launchers the PLA Navy also received about 40 A.244S Whitehead anti-submarine torpedoes for trial and evaluation. Some of these torpedoes were sent to the Xi’an-based 507 Institute (now Xi’an Precision Machinery Institute) for reverse-engineering. It is not clear whether this was consented by the Italian manufacturer. The Chinese-made A.244S, which was designated ET52, entered service with the PLA Navy in the early 1990s.

计划

在1987年,PLA海军从意大利防卫技术公司阿莱尼亚(Alenia)公司购买了一些B.515S三管324毫米鱼雷发射装置,在它的051型“旅大”(Luda)级导弹驱逐舰上安装。连同这些发射装置一起,PLA海军也接收到约40枚A.244S “白头”(Whitehead)反潜鱼雷用于试验和评估。一些鱼雷被送到西安的507所(现在西安精密机械研究所)。不清楚的是,这是否被意大利制造者同意了。中国制造的A.244S鱼雷被指定为ET52型在1990年早期内进入了PLA海军服役。

DESIGN

The ET52/A.244S is a lightweight, electrically propelled torpedo designed to be launched from surface combatant torpedo tubes and helicopters. The torpedo can engage enemy submarines in shallow waters. The torpedo uses a conventional layout with guidance system and warhead in the forward section, the battery in the middle section, and propulsion and steering systems in the rear section. The torpedo is 2.70m long, has a body diameter of 324mm and, with its shaped 34kg HE charge, weights 235kg.

设计

ET52/A.244S是一种轻型、电推进鱼雷,设计去从水面战舰鱼雷发射管和直升飞机发射。鱼雷能交战浅水域敌人的潜艇。鱼雷使用一种常规布局,制导系统和弹头在前部,电池在中部,推进和操纵部分在后部。鱼雷长度2.70米,直径324毫米,采用一个34公斤的成形高爆(HE)装料,重量235公斤。

When carried by helicopters, the torpedo uses a special device consisting of a parachute stabiliser/retarder and release mechanism to ensure that it makes a smooth entry into the water.

当被直升飞机携带的时候,鱼雷使用一个专用装置,由一个降落伞稳定/减速装置和脱扣机构组成,去确保它平稳进入水中。

GUIDANCE

The torpedo uses a CIACIO-S seeker consists of an acoustic homing head containing the transducer assembly, transmitter and related beam forming circuits, and a frame housing all the remaining electronic components. The homing head is capable of active, passive or mixed modes for closing onto its target. It can also discriminate between decoys and real targets in the presence of heavy reverberations by specially emitted pulses and signal processing.

制导

鱼雷使用一个CIACIO-S导引头,由一个包括传感器集合的声寻的头,发射机和关联波束形成电路,一个容纳所有的剩余电子元件的基座组成。导引头能够主动、被动或混合模式用于接近到它的目标。它也能够在出现大量回响的情况下采用特别发射脉冲和信号处理在诱饵和真实目标之间辨别。
