The Premier Collegiate Rocket
TXE-2 (Havoc) is TREL's Flight Engine and is one of the most advanced and complex engines in collegiate rocketry. Powered by high pressure RP-1 and LOx, Havoc surpasses many of its peers, taking the throne as the highest thrust regeneratively cooled, 3D printed rocket engine in the history of collegiate rocketry.
- Kerolox engine
- Regeneratively cooled
- Additively manufactured / 3D printed
- Nominally 3500 lb of thrust
- ~ 60s burn duration
- Pressure fed engine cycle
Thrust Vector Control (TVC), is a system in Halcyon allows us to adjust the rocket's trajectory during its upward ascent, ensuring our rocket stays on its path to the Karman Line.
TVC is comprised of a system of rings that are attached to our engine to rotate it around. Each ring is connected to a linear actuator that pushes and pulls on the ring.
We test the TVC system using a custom stand which simulates the 3500 lbs of force exerted by the engine in various directions, simulating a hotfire.
The structures team is responsible for producing nearly 70% of the rocket’s hardware by volume! The team uses carbon fiber to produce the bulk of the rocket’s airframe, which is mainly comprised of 6 panel skirts and 3 COPV’s (Composite Overwrapped Pressure Vessels).
Halcyon’s fluid lines and electronics are also routed on the outside of the rocket, underneath a composite raceway that is bonded to the tanks and airframes.
- Carbon fiber facesheets
- 8 - 30 inches in length
- Connect Halcyon's fuel and pressure tanks
Payload's mission is two-fold. First to prove that we can rapidly inflate and deflate a balloon during descent. This mission will pave the way for our eventual goal: to reach neutral buoyancy at a desired altitude. The second mission is to collect UV data from the mesosphere. This mission will prepare us to design a future payload to carry a 3U-sized biological sample to apogee.
- Drogue Chute - 50km
- Balloon Depoloys - 15km
- Main Chute - 5km
