The　factors　in　bullet＇s　shape　design　which　affect　the　drag　force　of　bullets　are　important　in　aerodynamics,　especially　in　ballistics.　In　this　paper,　based　on　traditional　researches　about　different　bullet　shape　designs,　nose　cone　design　of　the　bullet　is　mainly　discussed,　as　well　as　the　hollow　tip　and　the　rifling　on　the　appearance　of　the　bullet　are　also　included.　This　paper　adopts　Fusion　360　and　Ansys　fluent　to　calculate　and　model.　This　research　verifies　the　similarity　of　the　drag　coefficient　of　different　bullet　shape　design　at　a　low　speed　and　figures　out　the　best　shape　characteristic　coefficient　in　Haack　series　design,　while　some　problems　still　exists　in　the　influence　of　hollow　tips　of　the　bullet　to　the　drag　force.　©　Published　under　licence　by　IOP　Publishing　Ltd.
