The aerodynamic characteristics of the conical configuration with the nozzle are compared with those of a clean conical configuration and the differences are investigated by the comparison of the flow fields. As for the nose entry conditions (Alpha = 0 - 90 deg), at the angles at which the nozzle ramp isn't seen from the freestream, aerodynamic characteristics don't differ between two configurations. At larger angles near Alpha = 0 - 90 deg, the configuration with the nozzle has larger lift coefficient (C(sub L)) due to the lift produced by the nozzle ramp. As for base entry conditions (Alpha = 90 - 180 deg), the configuration with the nozzle has larger C(sub L), drag coefficient (C(sub D)) and lift to drag ratio (L/D). However at the angles at which the difference in the flow-direction projection areas is larger, C(sub D) increases. At supersonic flows C(sub L)-Alpha distribution smoothly shifts to higher attack angles when the nozzle ramp is attached. On the other hand, at subsonic and transonic flows C(sub L)-Alpha distribution dose not change smoothly. Moment characteristics also change, the combinations of attack angles and c.g. (moment center) which realize static stability increase.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
