A Balloon-based Operation Vehicle (BOV), which has been successfully developed at JAXA in the past two years for a new micro-gravity experimental method, is aiming a next stage of being a flying test bed of an air-breathing engine (pre-cooled turbojet engine) planed in 2008. In this paper, the aerodynamic characteristics of BOV obtained by CFD simulations are compared with wind tunnel experiments in 2005-2006. In addition, the latest experimental results for a new configuration with a main wing for a level flight are also presented.
