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.

New CNC Equipment

We have a new piece of equipment in our shop! The PRO6060 router from AVID CNC. This video is from the first time powering on the system and testing out the axes.

EVPR Mk.II Latest Electronics

The third revision of the EVPR Mk. II electronics are here! Still have some work to do on the battery charger, but the rest of board is working and testing on the vehicle can start.

Titan Oil Tank Progress

After a few design revisions, the oil tank for Titan is complete and ready to integrate into the airframe! The 6 quart tank was made completely in-house with exception to the filler neck and cap.

March 2020 Progress

Fit checks for the first Mk. II prototype board are complete and the board has been populated. The processor is powered via USB and accepting code!

Prototype Boards Arrived

The prototype boards for EVPR Mk. II are here! Time to start populating the board and checking out the design. Thanks to Georges Oates Larsen for the PCB layout and OSHPark for the awesome boards.

January 2020 Progress

One of our first milestones for 2020 will be testing the engine for Titan in a horizontal orientation. This will ensure that the oil system and structure is acceptable before adding of the drive system. The test stand is now assembled and undergoing fit checks.

November 2019 Progress

We’ve recently completed a prototype of the power transfer hardware that will be used on our next generation rotor design. Carbon brushes, held in place with a custom 3D-printed holder, transfer power to copper plates on the rotor. On-board batteries will remain, providing a backup power source.
