At NAL-KRC (Kakuda Research Center), the present authors are conducting cold-flow experiments, combustion tests and CFD (Computational Fluid Dynamics) analyses of linear-type aerospike nozzles to understand the flow field structure around the nozzles and to develop appropriate methodology for designing spike nozzle contours. Currently, two-dimensional inviscid calculations are being conducted for a full-length spike nozzle. In this paper, the numerical results for three different altitude conditions (high/medium/low altitude) are presented and compared with the experimental data for the same altitude conditions to validate the usefulness of the present calculations. The predicted pressure distributions on the spike nozzle surface for the high and medium altitude conditions show good agreement with the experiment data, while that for the low altitude condition shows somewhat insufficient agreement. On the other hand, in term of the efficiency of thrust coefficient, the calculated results for all three altitude conditions are in good agreement with experimental data.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
