Second Thrust Vector Control Test – PERUN Rocket Performance

Improved Guidance for PERUN Rocket

Last week, SpaceForest successfully tested the performance of the Thrust Vector Control (TVC) system. This was an improved version, following the first flight conducted in August 2022. The task of the 10-degree deflected BIGOS 6 rocket was to align for vertical flight, which it achieved immediately after leaving the launch pad. Further test flights of the TVC control are planned later this year.

How TVC Enhances Rocket Performance

Thrust Vector Control (TVC) is one of two control systems for the PERUN rocket, designed to lift 50 kg payloads to altitudes of up to 150 km. TVC allows precise control of the thrust vector from the main hybrid rocket engine, enabling the rocket to maintain its attitude and follow a predefined trajectory.

As a result, trajectory control brings multiple benefits: it decreases landing point dispersion, increases flight safety, reduces forces acting on the fuselage, and improves overall rocket performance.

Looking Ahead

The results of this second test confirm that the TVC system is functioning as intended. SpaceForest engineers are preparing for additional flights, which will further validate the guidance algorithms under real operational conditions.
