Numerical study of the aerodynamics of the head unit during an accident at the start under wind conditions

In the work numerical simulation of the flow around the bodies of the detachable head unit with an emergency rescue system and launch vehicle in the process of their separation in wind conditions is carried out with the determination of forces, moments and pressure distribution in a quasi-stationary formulation – a change in the distance between bodies is set discretely. The main task of the stage is to determine the influence of wind, propulsion jets and the distance between objects on gas-dynamic forces and moments. The main task of this stage is to determine the influence of wind, jets of propulsion system and distance between objects on gas-dynamic forces and moments.
