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.
