Hello Everyone,
This will be the build thread for “Our Children’s Future” (Henceforth called OCF).
Some quick stats:
Diameter: 10.75 inches
Height: 195 inches
Estimated empty weight: 95 Lbs.
Mason Hazzard came up with the idea for this rocket while talking about how cool it would be to do a group project together. Mason Hazzard noticed that AMW had some tubes on sale for a dirt cheap price. We threw these into an Openrocket file, played around with some things, and Our Children’s Future was born.
Who is working on what on the project?
Matt Fletcher (blackbrandt) will be working on the altimeter bay.
Cody Smith (codysmith) and David Nagy (littlemisterbig) will be in charge of “laminating” each airframe with a coat of epoxy. Cody and David will also be in charge of assembling the motor mount into the airframe, attaching the fins and making the fillets.
Connor McGrath (Conman13) Is responsible for the construction of the motor mount and overviewing the “lamination” of the airframe. He will also be painting a large portion of the rocket.
Jim Scarpine (jimzcatz) is the man who made this project possible. He volunteered to be our mentor for this project, and will also be donating the motor that this will be flying on. Thank you Jim!
Airframe: The tubes will be from AMW. They are cardboard with an OD of 10.75” and ID of 10”. We will be “laminating” each tube by it a thin coat of epoxy. We will joining the tubes together to form 2 lengths that are 76.5” long. The rocket will have 2 separation points.
Nose Cone: We have contacted Python Rocketry to build a nose cone for us. It will be a 4:1 ogive cone coming in at 40”. It will have space that will be made into a electronics bay for our tracker.
Fins, Bulkheads and Centering rings: Connor will be designing all of these on
CAD and Matt will use a CNC machine that he has access to for cutting them out. All of these will be ½” plywood and be given either a layer of fiberglass or epoxy.
Couplers: We are purchasing 4 body tubes. 3 will be used for the body of the rocket and the fourth will be cut down to make our couplers and Electronics bays. Because the body tube has a wall of .375” it will work perfectly for the use as couplers.
Charge Wells and Thrust Plate: Christopher Nilsen contacted us through facebook asking to be part of the project. He sent us some pictures of rocketry parts he machined out of aluminum and he can be called a professional. His work was amazing! He will be machining the charge wells and thrust plate out of aluminum for this project. Some of his work is attached below.
Electronics: We will have Full redundancy for deployment. We will be using an RRC3 and either an RRC2, Eggtimer flight computer or a Telemetrum. An Eggfinder or Derek's mini GPS tracker will be mounted in the nose cone for tracking Purposes.
Motor: Jim Scarpine has donated a motor for us to fly this rocket on. It is an EX motor cast by Burl Finkelstein. The motor is classified as a N2961. This is a very baby N, However it will bring this rocket quite high. It s a gorgeous bright Blue propellant.
The Open Rocket design file will continue to change throughout the project as we tweak weights and change small aspects of the design. The new File will always be kept updated below.
