The first ground test of the Pioneer-50K solid rocket propulsion system, developed for future Rocket Taiwan Cup, has been successfully completed!
It will be integrated into the SST3 rocket for this year’s Rocket Taiwan Cup exhibition category.

In liquid rocket engines, regenerative cooling is a common design. We utilized a self-developed optimization algorithm for the regenerative cooling design and fabricated the components using metal 3D printing technology.

This year, we’ve completed multiple tests, including liquid rocket engine tests, Asfaloth-2 flight test, and HTTP-4 hover flight test.
From every test, we gathered lessons and turned them into momentum for the next step.
Wishing everyone a Merry Christmas and a Happy New Year!

【"Never Gonna Let You Down #3" | HTTP-4 Tethered Hovering Flight Test-3】
The planned landing test was unsuccessful due to the rocket becoming entangled with the upper tether line. The rocket needs to be inspected and tested again.

C* value serves as one of the indicators of its combustion efficiency. Improving combustion efficiency is often achieved through adjustments to propellant injector design. As C* approaches 100%, combustion becomes more complete, resulting in a noticeable change in flame color.

The software design challenge is based on MIT Lincoln Laboratory’s Kerbal Space Program Differential Games open-source library. We employed Nonlinear Model Predictive Control to maneuver our agent satellite to capture a target satellite while evading another guard satellite.

For the first time, ARRC attempted a 120-second hybrid rocket engine hot-fire test.
To verify the limits of the hybrid rocket engine and evaluate the feasibility of its application in launch vehicles, several tests are still ongoing.

In addition to completing two HTTP-4 hovering flight tests and one Asfaloth flight test this year, it officially entered the liquid rocket system.
Merry Christmas and Happy New Year!

Our liquid rocket engine project has two design directions. Different from the previous test of hypergolic liquid rocket engine, this test uses hydrogen peroxide and hydrocarbon fuel as the first step toward entering high-thrust liquid rocket engines in the future.

HTTP-4 2nd flight test completed!!
This test lasted 25 seconds of flight time and was equipped with an M-path to confirm the control performance of the landing speed. The next step is to try the hopping test.

The guidance, navigation, and control (GNC) algorithm was computed on the flight computer in real time to command the single-engine dual-axis thrust vector control (TVC) system, dual swing cold-gas reaction control system (RCS), and adaptive thrust control valve.

To make the Tsuâ-Ing hybrid engine closer to the requirements of the Asfaloth sounding rocket, the solid fuel design can be adjusted to achieve a shorter engine length and lighter engine weight, for which the first hot-fire test was conducted.

“We had to start somewhere, either succeed or fail, and then build what we knew as we went along.” - Rocket Boys (October Sky) by Homer Hickam
It's a pity this year; we will continue to work hard to prepare for the subsequent flight testing.
Merry Christmas and Happy New Year!

HTTP-4 is the first rocket in ARRC which facilitates active roll control with a cold-gas reaction control system (RCS). The attitude estimation for closed-loop feedback control is provided by an IMU. The test results show that they agree well with the 6-DOF simulations.

HTTP-4 rocket is equipped with reaction control system (RCS) for roll control purpose. Two vernier thrusters enable the control of roll torque. Both cold-gas nozzles can generate a thrust of 3 N. Many integrated tests were peromed to investgate the roll control performance.
