Abstract
The presented work investigates the use of the adjoint state method for the trajectory optimization of a reentry vehicle. The trajectory is optimized using a direct optimal control method with single shooting transcription, where the gradients are evaluated using the adjoint method. This approach leads to a faster optimization process with results comparable to those obtained using the finite differences. The comparison between the adjoint method and the use of the finite differences will be detailed, both in terms of gradient computations and optimisation efficiency.
