The ILR-33 “Amber” (Bursztyn) rocket a key project of the Center of Space Technologies of Institute of Aviation. The main goal of the self-funded initiative is to demonstrate key technologies for modern suborbital rockets and small launch vehicles. "Amber" is a highly scalable, cost-effective and green platform enabling conducting experiments in microgravity at altitudes of up to 100 km.
The design has been validated on the 22nd of October 2017, during the first flight test of the “Amber” platform. Due to legal constraints, the ceiling of the test flight has been limited to 15 kilometres. Only a fraction of the oxidiser tank volume has been used. It is the first Polish sounding rocket enabling high-altitude microgravity tests since 45 years. What is more, ILR-33 "Amber" is the world’s first sounding rocket that utilises hydrogen peroxide with concentration exceeding 98%.
