title = "Periodic optimal saw-Tooth flight of motor gliders with retractable jet engine",
abstract = "The range performance of motor gliders with a retractable jet engine is dealt with. This performance topic is treated as a periodic optimal control problem, addressing a flight type known as saw-Tooth mode. The saw-Tooth mode consists of continually repeated cycles each of which comprises a climbing phase with the engine extended followed by a gliding phase with the engine retracted. It is shown that the maximum range achievable with the optimal saw-Tooth mode is larger than the maximum range of optimal steady-state cruise where the engine is permanently extended. With an optimization treatment based on energy considerations, analytical solutions are developed. Furthermore, a treatment using a point mass dynamics modelling is performed and an efficient optimization method is applied for solving the maximum-range problem.",
