Singular extremals are derived by means of Legendre-Clebsch necessary condition applied in transformed system of state and control variables; these are obtained as circular orbits along which thrust is zero and intermediate thrust arcs are found in Lawden's analysis; since solutions satisfy only weak form of Legendre-Clebsch condition question of their minimality remains unanswered.
