Abstract
The development of future launchers leads CNES and ONERA to be interested in concepts of winged vehicles with horizontal landing. From the experience acquired on the vertical takeoff vertical landing (VTVL) concept, a glide back recovery concept is studied in this paper using a similar control approach. It involves a guidance algorithm which relies on an indirect optimal control method based on the Pontryagin maximum principle. Glide back recoveries expose the winged vehicle to wind disturbances. Therefore, the guidance model incorporates wind management. The wind profile is estimated onboard the vehicle using an extended Kalman filter. Promising results have shown that this approach can be deployed in realistic flight conditions.
