Thrust Vector Control Test – Successful Flight Validation
What is the Thrust Vector Control system?
The Thrust Vector Control (TVC) system is one of two key control mechanisms of the PERUN rocket. It enables precise control of the main hybrid rocket engine’s thrust direction, which allows the rocket to adjust its attitude mid-flight.
As a result, PERUN can follow an optimal trajectory and effectively counteract external disturbances such as wind gusts. This capability reduces landing point dispersion, increases safety, minimizes fuselage stress, and boosts overall mission performance.
From ground tests to flight validation
After several successful tests of the mechanical design — first in a small-scale experiment with the SF Test engine, and later during the full-scale SF1000 engine test — the time came to validate the guidance algorithms in flight conditions.
For this purpose, we built a smaller rocket named BIGOS 6, which successfully completed its first flight on August 26th. The goal of this test was to bring the rocket to a vertical orientation after launch from a tilted tower.
A successful result and what comes next
Thanks to the TVC system, the rocket achieved perfect stabilization, confirming the design’s reliability and precision. With these results, our team confidently moves toward the next stage — the upcoming PERUN Thrust Vector Control test — which will further advance the development of Poland’s first suborbital rocket with active guidance.
Next flight test is coming soon – stay tuned!
