Abstract
This paper investigates unmanned aircraft guidance for a severe storm penetrator to assess the feasibility of such a mission and to optimize ingress in terms of flight time and exposure to precipitation. Understanding guidance-layer behavior and deriving control strategies will provide tools for developing mission-level concepts of operation and making vehicle design tradeoffs. A backward propagating wave front algorithm based on ordered upwind methods is developed for guidance-layer planning of severe storm penetration. Target areas for investigation by the aircraft are identified within simulated storm wind, hail, and precipitation data. The simulated data are used to determine the feasibility of storm penetration to the points of interest, along with calculating airframe exposure to precipitation. Ingress planning is also considered for a dynamic wind field using a receding horizon control approach to adapt the flight path in response to environmental changes.
