WebJan 15, 2024 · According to primer vector theory, the necessary conditions for the optimality of an impulsive trajectory can be stated as follows (Lawden, 1963): 1. The magnitude of the primer vector must be one at the instant of impulse and less than one elsewhere. 2. The thrust vector must be aligned with the direction of the primer vector. 3. WebJan 1, 2013 · 10.1 Introduction. In this chapter we develop a general theory of optimal spacecraft trajectories based on two pioneering works: Breakwell [ 1959] and Lawden [ 1963 ]. Lawden introduced the concept of the primer vector, which plays a dominant role in minimum-propellant trajectories and also in other types of optimal trajectories.
