空気の粘性を考慮した空力利用型軌道間輸送機 (AOTV) の最適軌道について

抄録

In this paper, minimum fuel consumption trajectories and histories of control actions on two different orbital plane change missions, the GEO-LEO mission and the LEO-LEO mission, with consideration of the constraint of aerodynamic heating and the viscous effects on AOTV aerodynamic characteristics, have been investigated. For results, it has been made clear that viscous effects for the fuel consumption on both missions are little. However the effects for optimal trajectories and histories of control actions were different for each mission. It has also been made clear that in the case of GEO-LEO mission the air viscosity is needed to be considered to do the guidance for the AOTV. However for the LEO-LEO mission the air viscosity is not necessary in order to do the guidance.
