Abstract

The direct force active control technology of direct gas composite is an important development direction and key technology of precision guidance weapons, which provides an effective power for the aircraft to carry out great manoeuvrability and agile flight. When the vehicle adopts direct force / aerodynamic composite control, the aerodynamic characteristics and jet characteristics are no longer independent of each other, but form a complex flow field structure, which strongly changes the aerodynamic forces acting on the vehicle. This paper makes the design study of the aerodynamic characteristics and jet characteristics of direct gas composite, establish the aerodynamic model and direct force model that can accurately describe the side jet interference effect. Based on the WENO method, this paper calculates the direct force jet through the grid generation and the setting of initial field and boundary conditions, mainly analyses the operation of double jet at typical altitude and the interaction between jets under different flight conditions or flight conditions. The effective conclusions of the coupling effect of aerodynamic characteristics and jet characteristics under some typical conditions are obtained, which provides a research basis for the analysis of the interaction between multiple jets of direct force aircraft with jet control mode.
