Rocket Team 2021-2022

The First Year of the Team

Launch 3 - Pasco

Missel Madness - Tri-Cities Rocketeers

For this 3rd and final launch of the 2021-2022 academic year, our team attended the Memorial Day weekend launch event in Pasco, WA.

For this launch our team will be focused on the following:

Continued L1 and L2 certifications
Live telemetry
Use of Eggtimer Quantum flight computers for drogue/main chute deployment
Emphasis on flight data collection
- Comparing flight data to Rocksim simulation data
Testing larger L2 motors (Class J, K, and L)

Rocket Information

LOC Precision's Hyperloc 300 is the rocket kit our team members built and are using for the L1 and L2 certification launches. This rocket can be reused for both launches and just needs a small motor adaptor depending on the diameter of the motor

Flight Simulation and Testing

Considering our team's goal of competing in the IREC sounding rocket competition, it is important to be able to accurately predict flight data such as max altitude, max velocity, drift distance, and flight path. Using Rocksim we are able to run accurate simulations with specified rocket dimensions, weight of individual components, exact motors being used, weather conditions, and parachute deployment altitude(s), among other variables. The simulation data is then compared to actual flight data, which is collected using Eggtimer Quantum flight computers. The error between the simulation and flight data can be used to further increase the accuracy of apogee and max velocity predictions for future flights.

Flight Computers

After comparing various flight computers, our team decided to use Eggtimer's Quantum flight computer. A few of the key features are that it is wifi enabled, has 2 deployment channels, simple user interface (accesseble from any phone or wifi enabled device), records flight data for multiple flights, and only takes about 3-5 hours to solder and assemble.
