Mission re-planning is an effective approach to reduce or even eliminate the negative impact of thrust fault on launch vehicles, and appropriate re-planning decisions require a comprehensive understanding of the residual capacity of launch vehicles after fault. This paper introduces the concept of reachable domain for launch vehicles to evaluate the post-failure residual capacity and proposes a search-based algorithm for the reachable domain computation. The reachable domain for launch vehicles is first defined by orbital elements to describe the high-dimensional accessible orbit set, and a dimension-reduced form is then formulated by reasonable engineering assumptions, which provides practical and intuitive insight to facilitate the mission re-planning decisions. Moreover, a search-based algorithm is proposed to compute the boundaries of the reachable domain with no need of proper initial guesses as compared with mathematical optimization methods, yet it still provides accurate results. Simulation examples demonstrate the residual capacity of launch vehicles with different extents of thrust fault, which reveals the effectiveness and practicability of the reachable domain concept for making appropriate re-planning decisions.
