In this paper, the structural test and safety evaluation of astronautical structures such as nose cone assembly of sounding rocket were presented. Structural strength tests of the nose cone assembly with body and stage in the scientific sound rocket were performed with load level of 100% limit load and 2O0% ultimate load of design lift force. Safety factors in each part of the nose cone assembly were calculated at these two load levels. As the result of structural test, the safety factor of the nose cone assembly were evaluated to be above 10, which is saying that the structure is safe enough, thus optimal design might be needed for light weight of rocket.
