First Full Scale Isotank Cylinder Completed

Tonight we finished machining the first cylinder section of a propellant tank for Portland State Aerospace Society‘s next gen launch vehicle, LV4! This tank section is 12 inches in diameter and nearly 28 inches long. Two sections will be welded together to complete the fuel tank. The machining process removed about 70% of the weight of the cylinder. Also shown is one of the 6-inch-diameter test articles, completed earlier this month.
