Prediction of trajectories of dropped weapon/store from modern nyorid fighter bomber is still or great significance. Computational aerodynamics plays an important role in this domain. Tne reason is that experimental investigation is very expensive and requires specially equipped wind tunnels and testing facilities. Such laboratories are only available in in few countries. This paper presents a computational method for predicting weapon/store trajectories at tne vicinity of the parent aircraft wnich is a fighter bomber and at different flying conditions. Three different computer programs are prepared. to fulfil this tasic. Tne first two programs are used in the calculation of tne singularity distribution modelling the aircraft components and the weapon/store as well. Tne ultra program is a six degre-es or freedom trajectory program.
Computed trajectories are compared with measured ones with good accuracy. Tne results show that the computational tecnaique could give a good potential in this domain and could be considered as a cost effective one.
