“…Therefore, the energy-efficient launch approach has become a research hotspot, with the goal of improving energy efficiency and thus reducing the launch cost. Many advanced launch technologies have been researched [5][6][7][8][9][10][11][12][13], such as the multidisciplinary design approach [5], the use of a space elevator [6], reusable launch vehicles [7,8], and an electromagnetic boost launch system [9][10][11]. Using these technologies, reusable vehicles and electromagnetic boost launch system are proven to have high feasibility and efficiency.…”

“…They exhibit great advantages over chemical energy launched rockets, i.e., EMSLs can launch rockets with a larger useful load and a higher acceleration, reusability, energy conservation, efficiency, environmental protection, and safety. EMSLs have been developed with applications for various space launch modes from ground-based launches [10], airborne launches [11], the electromagnetic acceleration of superconductors [12], and the augmentation of a permanent magnet linear synchronous motor [13]. In 2018, McNab evaluated a two-stage-to-low-Earth-orbit projectile for space launches.…”

“…Since the reusable two-stage TBCC-RR launch approach still consumes a large amount of energy, the EMB launch approach can significantly reduce the required fuel quality and launch cost. Based on Reference [10], for every 1 kg of fuel saved, the costs will be reduced by around USD 19,000. Moreover, the proposed three-level launch approach offers the advantages of reusability, environmental protection, and safety.…”

Due to its advantages of high acceleration, reusability, environmental protection, safety, energy conservation, and efficiency, electromagnetic energy has been considered as an inevitable choice for future space launch technology. This paper proposes a novel three-level orbital launch approach based on a combination of a traditional two-level orbital launch method and an electromagnetic boost (EMB), in which the traditional two-level orbital launch consists of a turbine-based combined cycle (TBCC) and a reusable rocket (RR). Firstly, a mathematical model of a multi-stage coil electromagnetic boost system is established to develop the proposed three-level EMB-TBCC-RR orbital launch approach, achieving a horizontal take-off–horizontal landing (HTHL) reusable launch. In order to optimize the fuel quality of the energy system, an artificial intelligence algorithm parameters-sensitivity-based adaptive quantum-inspired glowworm swarm optimization (AQGSO)is proposed to improve the performance of the electromagnetic boosting system. Simulation results show that the proposed AQGSO improves the global optimization precision and convergence speed. By using the proposed EMB-TBCC-RR orbital launch system and the optimization approach, the required fuel weight was reduced by about 13 tons for the same launch mission, and the energy efficiency and reusability of the spacecraft was greatly improved. The spacecraft can be launched with more cargo capacity and increased payload. The proposed novel three-level orbital launch approach can help engineers to design and optimize the orbital launch system in the field of electromagnetic energy conversion and management.
