摘要

本文的目的是介绍目前在空军技术学院进行的模拟测试的部分结果。这些试验涉及LBCw-10飞行炸弹的飞行动力学,该炸弹是在ITWL研制的,目前正在进行现代化。模拟是使用为这些研究的需要而开发的专有软件进行的。本文给出了一个经典的弹体空间运动模型和弹体空间运动的基本数据。详细描述了气动力的计算方法,并辅以使用商用PRODAS软件获得的示例性气动特性。此外,还提出了考虑风场变异性,特别是大气湍流的方法。采用随机风场模型。给出了计算结果的说明,这些计算结果将用于涉及使用主动航迹控制的炸弹现代化过程中。

MODEL OF BOMB AIRDROP DYNAMICS AT TURBULENCE CONDITIONS
The purpose of this article is to present partial results of simulation tests currently conducted at the Air Force Institute of Technology. These tests concern the flight dynamics of the LBCw-10 flight bomb, which was developed at ITWL and is currently undergoing modernization. Simulations were carried out using proprietary software developed for the needs of these studies. The article presents a classic model of spatial motion of a bomb and basic data of this object. The method of calculating aerodynamic forces is described in detail, complementing this description with exemplary aerodynamic characteristics, which were obtained using commercial PRODAS software. Additionally, the method of taking into account the variability of the wind field, and in particular the turbulence of the atmosphere is presented. A stochastic wind field model was used. Illustrative results of calculations are shown, which will be used in the process of bomb modernization involving the use of active flight path control.
