The structures team consists of 3 members: Richard Estes, Corey Silcox, and Eric Free. We are the team that is responsible for building the airframe that the other sub-teams will use to fly, secure, and protect their equipment. The airframe is the empty rocket and includes parts like the nose cone, body tubes, fins, bulkheads, and things of that nature.
This year’s rocket is going to be something special. The nose cone design is going to be in the ellipse family as it gives the best CD with subsonic flight. We have many ideas that are innovative and are in the process of being tested and are looking forward to implementing some on the rocket. These are preliminary and are subject to change, but we will update this regularly to keep the most up-to-date information available.
The structures team has many responsibilities that include the following:
· Body Materials
· Fin Design and Flutter Analysis
· Interfaces and Bulk Plates
· Nose Cone and Boat Tail Design
· Transition Piece
· CG, CP, CD, and Stability Calculations
Below are some CAD images that were made and assembled by the team and show our early idea of how things are going to look.
Here is a picture of our dart. This is the payload end of the rocket. This is the part that will be flying to 5280 ft. This shows that we are planning to have a dual deployment and break at the nose cone and fin section (The blue parts are going to fall off). This part of the rocket is not powered, meaning that it contains no motor. This dart will just coast to apogee after the booster falls off. There will be a smoke charge in the boat tail so that we can keep watch over the dart as it flies out of normal sight.
This is our booster. It is our business end of the rocket. Here, we are going to house the rocket motor that is going to send us to the proper altitude. Even though the competition is to 5280 feet, the booster only flies to around 1000 feet and lets the dart finish the journey alone. This design requires us to drop the booster off the dart smoothly as to not interfere with the darts flight. The booster is a single deployment at the top. The transition piece will eject and be followed by the parachute.
