轻型鱼雷及飞机投放装置

本文主要概述了轻型鱼雷的性能、飞机空投鱼雷使用条件及飞机投放鱼雷装置,同时也对主要直升机性能作了概括。这对于使用轻型鱼雷进行空投反潜具有重要参考价值。     

直升机攻潜时的接近航向

直升机攻潜策略是反潜战中值得研究的一个问题。研究攻潜策略实质是确定最优投雷点,即直升机的最优接近航向和投雷时刻。本文研究的结果是:如果目标作等速直线运动,则直升机的最优接近策略为平行接近法。

Vulnerability assessment to projectiles: Approach definition and application to helicopter platforms

Survivability is defined as the capability of a platform to avoid or withstand a man-made hostile environment. Military aircraft in particular, but also other kinds of platforms subjected to external, impacting threats, are commonly designed according to increasing survivability requirements. The concept of survivability was first formalized by R. Ball in 1985 in its seminal work on combat aircraft survivability. On the basis of the theory presented in his work, many computer programs have been developed which implement the modelling techniques and computations required by vulnerability assessments. However, a clear and general view of the operative computational procedures is still lacking. Moreover, to date only a limited number of applications to helicopter platforms have been investigated in the survivability field, even though these platforms experience numerous flight conditions exposing the system to different types of threats. In this context, this work aims at establishing a multi-purpose general framework for the vulnerability assessment of different types of platforms subjected to external threats, with a focus on helicopters. The in-house software specifically developed for this application is here described in detail and employed to present a case study on a representative military helicopter.
