Introduction

Micro Rocket Design Services (MRDS)

The trend of miniaturization has been applied to the research of rockets to develop prototypes of micro rockets. This site shows the development of a web-integrated prototyping system for three-dimensional micro rockets (design and manufcturing guide).
Usability of the web-based system is quite effective especially in terms of accessibility. Different from general micro machining , the geometry of micro nozzle requires special design and fabrication system.
The main parts of a micro rocket are divided into a nozzle, a combustion chamber, and a housing. The most critical design in a micro rocket is the geometry of micro size nozzle. Of available design methods, the method of characteristics was applied in this service. A Fortran code was implemented to solve the equations for method of characteristics. The design tool was modified and integrated with a web-based interface.
The calculated nozzle profile is fed back to the designer as a text file. For manufacturing, the designer has two options, 1) use the Computer Numerical Control (CNC) code generator provided in this service from the web server, or 2) read the text data into a commercial CAD system to make a three-dimensional nozzle geometry and to generate a CNC code using any CAM system.
In this service roughing and finishing tool paths are generated automatically in the server, and the mechanical micro machining process may fabricate micro nozzles in a rapid manner.
