Title    Spiral Drum for 64 Micro Sound Bombs

Abstract With the development of modern warfare, a large-capacity magazine is needed, Led to the emergence of spiral drum. Describing the working principle of the spiral drum, the advantages and disadvantages of the spiral drum , the development status at home and abroad .Clarifying the problems the subject wants to study and the means to solve the problems .The spiral drum is for 1964 type 7.62mm silenced assault shells . Spiral groove is use for positioning and orientation, The paper also containing the selection of the overall program , the main part of the spiral drum are the internal rotating body, the central axis of the outer cylinder and cylindrical torsion springs. using pin positioning, identifying the various parts and Ramming mouth shape and size, considering the force of bullets, spiral drum shells for the bomb timeliness spring parameters of the problem. Drawing dimensional engineering drawings by using autocad software and using solidworks software to draw three-dimensional map. Going further reflection on the results of the design ,then identify problems and optimize the design.
