Stuart's Rocket Motor Development Pages
Just a few pages here to show some of my motor development projects. Everything I do is based on Sugar Propellants but most also will work for any other type of propellant. The work to date falls into the following categories:
|1/2 Inch Aluminum Motors|
Original design of the 1/2 inch reusable aluminum motor. All of the parts are "turned" on my drill press.
|Rolling Your Own|
Technique for making fuel grains by rolling them out and cutting to length. These then work in the above motor
|Motor with Delay and Charge|
My latest motor using the above techniques. Separate chamber for delay element and charge.
|Nozzle With Graphite Insert|
Latest nozzle design for "bigger" motors (B-E) with a graphite insert.
Step by step directions to make them for yourself
|Melt/Cast Grain Process|
Making sugar propellant grains for 38mm Aerotech hardware
Assembling the motors in 38mm Aerotech hardware and static test results
Graphite Nozzles for 38mm Aerotech motors can be turned with a drill press!
Flight test images/video and accelerometer/altimeter data
|38mm Custom Hardware|
Hurray! I got a lathe! So I made a motor with a stainless steel nozzle insert.
|76mm Custom Hardware|
Scaling things up a bit...
