A recent article in online manufacturing newsletter got me started on this project. The APKWS (Advanced Precision Kill Weapon System) adds a laser guidance unit to a standard 2.75" rocket. The guidance unit can be installed between the warhead and rocket motor of existing standard unguided rockets. I did the 3D design work in Sketchup and 2D in AutoCAD. I tested the flight characteristics with OpenRocket. The body is a T50 and the finished model will be about 26" long. The image is the 3D model exported from Sketchup. I have started 3D printing some of the parts while waiting for the remainder of materials to arrive.
