Patent ID: 11247770

Abstract:
A vortex generator system has at least two vortex generators protrudable from an outer mold line of a vehicle surface at a location upstream of a cavity leading edge of a cavity in the vehicle surface. The vortex generators are spaced apart from each other and oriented such that the vortex generator aft ends are nearer to each than the vortex generator forward ends. The vortex generator lengthwise direction of each one of the vortex generators is oriented at a vortex generator directional angle relative to a direction of an airflow. The vortex generators are configured to generate a pair of counter-rotating vortices when the airflow passes over through or over the vortex generators. The counter-rotating vortices interact to produce a downwash of air away from the cavity that urges the store away from the vehicle as the store exits the cavity.
