Introduction Three beautifully crafted parts were made by GBS Gearbox Services International (Schaaf- en Boorwerk Rotterdam B.V.); a brand new set of three AL 7075-T6 clamp band rings and an AL 6082-T6 fairing. These are crucial structural components for the Stratos II rocket and thus the highest degree of accuracy and finishing are required. Clamp band…

Recently we received two very nice 1.5 m long, heat resistant fibreglass epoxy composite tubes from Teakle Composites for the Stratos II rocket. The tubes were originally intended for both the payload and parachute compartment. The nose-cone supplied by Futura Composites however already contains a tube section used for the payload bay. Still, one of the…

As reported, two solid fuel grains where produced last week. After casting the molten fuel into the liner, it shrinks significantly during cooling. This shrinkage gives rise to a risk of internal porosities and tears in the grains. This porosities will cause uneven regression of the fuel grain and less stable burning. This is…
