Book Description
Reflecting the results of twenty years; experience in the field of multipurpose flights, this monograph includes the complex routes of the trajectories of a number of bodies (e.g., space vehicles, comets) in the solar system. A general methodological approach to the research of flight schemes and the choice of optimal performances is developed. Additionally, a number of interconnected methods and algorithms used at sequential stages of such development are introduced, which allow the selection of a rational multipurpose route for a space vehicle, the design of multipurpose orbits, the determination of optimal space vehicle design, and ballistic performances for carrying out the routes chosen. Other topics include the practical results obtained from using these methods, navigation problems, near-to-planet orbits, and an overview of proven and new flight schemes.

Book Description
The calculus of variations is used to obtain optimum three-dimensional interplanetary transfer trajectories for a specified power-limited vehicle. The constant thrust program with coast capability used is governed by two-body orbital mechanics. The trajectory is broken up into departure and arrival spirals and a heliocentric transfer. The initial and terminal states for the spacecraft are circular-equatorial parking orbits about the departure and arrival planets. A minimum heliocentric distance for the spacecraft of .723 AU was maintained. The values of the parameter for the propulsion system modeled reflect those for Inertial Electrostatic Confinement (IEC) fusion and plasma linear driven Magnetized Target Fusion (MTF). The majority of the launch dates are from the years 2024 to 2026 Numerical results are presented for optimal Earth-Mars and Earth-Jupiter trajectories obtained using VariTOP (Various Trajectory Optimization Program), which is a low to mid-thrust trajectory optimization and analysis program developed at the Jet Propulsion Laboratory (JPL).
