Project Therion

Therionrender

After a semester of work, our competition rocket is beginning to take shape. At the team meeting earlier this week the rocket became “Project Therion” the many-headed dragon of biblical lore. Our rocket is designed to ascend 10,000 ft, where it will deploy a small pilot parachute. The rocket will descend under the pilot to 5,000 ft. At 5,000 ft, a 67 foot parafoil will unfurl from within the rocket. A flight computer will guide the descending vehicle back toward a designated landing site.

All of the teams have been working hard on the pieces necessary for this vehicle to fly. A brief overview of the last semester  for each team is below.

 Avionics:

Avionics is developing a Linux-based Guidance Navigation and Control (GNC) computer to help the parafoil find its way home. The instruments were designed as a Beagle Bone cape, which is currently being manufactured. The avionics instrumentation includes GPS, barometric altimeter, nine degree of freedom sensor, and a pitot tube.

Propulsion:

Propulsion has very nearly finished its responsibilities for getting Project Therion up to 10,000 ft. A 4-grain 98mm motor case arrived at the lab recently. Inside of this motor case approximately 4.8 kg of propellant will wait to push the rocket skyward.

Structures:

Structures is beginning the process of learning how to build a gargantuan 6in diameter, 10 ft tall rocket. The composites that form the majority of the structure of the vehicle will be the largest done by rocket team in recent memory. A number of technology demonstration projects are underway to build the institutional knowledge necessary for this project.

Payload/Recovery:

Deploying the parafoil to safely recover our rocket will require a new type of deployment mechanism. Both Payload and Recovery have been working to design the hatch to eject the parafoil. Recently, two possible designs were tested in a wind tunnel.
