Especially, a rotorcraft equipped with an imaging camera can gather geographic information around the rover and enables making of a smart strategy for the exploration. The development of such a rotorcraft, however, must solve some difficulty due to the thin Mars atmosphere. This is because the aerodynamic characteristics of the rotor depend mainly on the Reynolds number (Re) that decreases due to the thin atmosphere. In this paper, the aerodynamic characteristics of rotors were experimentally investigated to access a capability of the hover performance of the rotor in a very low Reynolds number regime (Re = 10(exp 3) to 10(exp 4), Ultra-low Reynolds number) that is expected in the thin Mars atmosphere. Based on the experimental investigation, the feasibility of such a rotorcraft was demonstrated., 資料番号: AA0047897023}, pages = {127--133}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)}, title = {Feasibility study for a small Mars exploration rotorcraft}, year = {2005} }
