Abstract: The invention reduces the impact of flowfield forces on objects launched from high speed aircraft during flight. For example, the invention provides a solution for overcoming ejection windblast injuries to pilots and increases the probability of injury-free or low-injury ejection. The gas flow is used to rapidly create a very short duration protective “bubble” in the incoming air flow ahead of the ejecting pilot. The bubble reduces the local flow velocity and aerodynamic forces on the pilot during the injury-critical time period of ejection. The invention also is suitable for reducing the intensity of flowfield forces that act on released military aircraft ordnance, such as bombs and missiles.
