Modeling technique for advanced adaptive aircraft catapult devices

Abstract

This article represents approaches to the configuration and modeling of adaptive aircraft catapult devices intended for forced separation of aircraft guided missiles from the air vehicle. The creation of such a device is a promising direction of research. The adaptability of such a device lies in the fact that in all air vehicles flight modes, the necessary and safe parameters for separating the air weapons from the carrier are provided. One of the variants of such a device with a hydraulic executive part is considered, its main parameters are determined to meet the requirements for the compartment safety and the possibility of regulating the flow of this process. The computer modeling technique is based on the use of approved information technologies SolidWorks, SimInTech and EULER, which allow solving multiphysics tasks, as well as reducing the full-scale experiments volume due to their use. As a result of comparing the results of mathematical modeling and experimental studies, it was found that the model of the adaptive aircraft catapult devices, developed on the basis of the methodology, describes the processes of payload movement fairly accurately.
