abstract = "The aim of this study is to model launch vehicles with focus on
3-DOF trajectory optimization using a modular approach. Despite
the large number of operational launch vehicles, they usually
consist of basic components and subsystems. In other words, a
launch vehicle is an assembly of stages, which in turn is divided
into propellant system and engine, and the engine is an assembly
of basic components such as pumps, turbines, combustion chamber,
and nozzle. To allow future extension and reuse of the codes, a
modular structure using object-oriented programming is used. Two
formulations of state equations of the trajectory and two
optimization methods are described. The launch vehicle performance
will be measured by payload mass for a given mission. The
simulations of the VLS-1, Ariane 5 and VLS-Alfa were performed and
showed good agreement with the literature.",
