This week lab is solid propellant burn rate test.

solid propellant is one of the rocket 'fuel'

Since this is quite dangerous, i will not disclose the chemical that we used. :)

Step 1 : Prepare a certain amount of chemical A(Fuel)

in this case, we used 69g of fuel

Step 2 : Prepare in a separate container chemical B (oxidizer)

8g of chemical B.

Step 3 : Mix them together and use a sifter to make it as smooth as possible.




Step 4 : Prepare the epoxy which act as a binder.

the west system epoxy ratio is 5:1 which is 5 resin and 1 harderner and the curing time is about 12 hours.




23g of epoxy

Step 5 : Pour the epoxy into the mixture.


Step 6 : Mix it properly using hand.


Step 7 : Put the mixture into PVC pipe


Step 8 : make a hole


and let it cure for ~12 hours.

Final product.

this is just burning the propellant.
no nozzle, rocket casing, rocket, missile or what so ever because it is dangerous when dealing with that. :p
