Pat6 (6" Patriot)

[MasonH]

I get bored. A lot. I design rockets. A lot. Here is my latest idea and design: a 6" scale M104 Patriot missile.

80" tall
75mm motor mount
Dual Deploy
Main chute in the nose
Glassed phenolic tubes

Enjoy, and I would appreciate any feedback! View attachment Pat6.ork

Hey Mason,here is a 3 fin Patriot gone bad...sorta. 98mm with three 1/2" rings screwed to the airframe.
6" Phenolic with one wrap of 6 or 7 oz..West Systems.
Dual deploy..nosecone is bulk headed.
Fins were ordered over the phone but Frank sent me for 54mm so I went with the look.
primer is being sanded off and primed white soon.
I would like to do a 75mm motor mount and cluster canister like the 54mm 2550 in the picture but maybe with Blue Tube if it's compatible
.

Is it stable? My main concern with my design is that on larger M motors and all the epoxy and reinforcement in the rear, it will be unstable or marginally stable at best.

Actually this was designed for not more than an Aerotech 98mm 2 grain casing.
The motor mount was made solid and slid into the airframe before screwing.fin to fin 6oz glassing,and fins were tacked with flexible 5min epoxy instead of CA.
4 fillets for every fin to finish the airframe (2 under 2 above.(Coloidal Silica)
I haven't done weights or balance yet,
I wanted to do some kind of weight chamber by drilling into the nosecone bulkhead and adding a 38mm tube.

To Do: Get a height measurement and a weight on a newly found Postal scale that my brother had.
