Abstract
We optimized the launch trajectory of an laser-sustained-plasma-type (LSP) laser propulsion rocket at an altitude of 500 km by considering transmission efficiency. The launch cost was calculated based on the results of trajectory calculations. The transmission loss was considered to be the effect of atmospheric turbulence and focusing the performance of the lens. In the optimization problem, the Legendre–Gauss–Lobatto (LGL) method was used for discretization, and the sequential quadratic programming method was used to solve the optimization problem. The payload ratio was 18.0% with a laser power of 200 kW. In the launch calculation, the costs of the laser, electricity, propellant, and airframe were considered for the experience curve effect. The calculation indicated the cost of 267,000 launches was 29.1% of the cost of chemical propulsion.
