The paper describes an algorithm for determining a class of fuel-optimal spacecraft transfers in a central Newtonian gravitational field with a restriction on the flight time. The algorithm relies on an indirect optimization method, based on the satisfaction of optimality conditions for a multiple-impulse maneuver. The determination of the unknown three-impulse trajectory is reduced to the solution of a one-parameter family of boundary value problems, with the initial approximation in the first problem being a known solution corresponding to the case of unconstrained flight time. The quantitative characteristics of the algorithm are examined.
