This week we completed and delivered the LV4 isotank to Portland State Aerospace Society. This tank will be used as a ground test article to verify the tank design before the flight articles are built. The completed tank is 55.4″ long and 12″ in diameter.

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.

We’re excited to be partnering with Portland State Aerospace Society on developing small scale isogrid propellant tanks. This week we delivered a 6 inch diameter sub-scale article for testing. The tank was produced using our new CNC router equipped with a rotary axis.
