Complete Rocket Integration Minus Pyrotechnics or CRIMP is the dress rehearsal or rocketry. During CRIMP all parts of the vehicle are integrated. The entire vehicle is then assembled in flight configuration. This allows us to verify all interfaces on the vehicle. This is particularly important on a rocket like Therion which is built from several highly modular components. From the top of the rocket to the bottom the components are as follows: payload, backup recovery, avionics, parafoil recovery, and the fin can.
The payload section was integrated today building on several weeks of work designing and fabricating the structure. The payload structure has the difficult task of meeting the requirements of two groups. Both OpenCV Mapping and the DBD Plasma Drag Reduction experiments rely on the nosecone for structure.

The next section of the vehicle is the backup recovery section. This portion of the vehicle contains the 9.5ft diameter main parachute and the 3.5ft drogue parachute.

The avionics section is the 12in piece of coupler between the backup recovery section and the parafoil recovery section. The avionics is at the heart of many vehicle interfaces because it commands most events and tracks the progression of the flight.

Attached to the bottom of the avionics bay is the parafoil section. The parafoil section contains the pilot parachute mortar, parafoil bay, and actuators necessary for guided recovery. The parafoil section is one of the most complex parts of the rocket. CRIMP allowed us to verify the structural and electrical connections between the parafoil and the rest of the vehicle.

The last section of the vehicle is the fin can. The fin can houses the rocket motor that will propel Therion to 10,000 ft. The fin can also has the carbon fiber foam core fins which keep Therion passively stable in the proper orientation during flight.

The entire rocket was spread out on the integration table in the Rocket Team lab. After assembly the rocket was returned to its components in preparation for the upcoming flight test 0. A list of action items has once again been compiled. We have a lot of work to do over spring break, but by next weekend Therion will be ready to take flight.
