Annual Egg Recovery Competition

Last weekend November 5, 2016 CPSS went to the launch site of the Friends of Amateur Rocketry for the Annual Egg Recovery Competition. The launch was a final step of a five week design challenge. Six teams of new members, each lead by one experienced rocketeer, have launched their certs. Through the day we had a chance to see multiple successful take offs, recovered rocket bodies, and cracked eggs. 2016 champion is Beefy5layer, with total score of larger then zero.

2016-17 launch season is officially open. More launches are to come in December, March, and June!

Separation Test

Cal Poly Space System’s successfully tested the separation device for apogee deployment of the drogue parachute. The mechanism uses a pyrotechnic charge to shear 8 nylon machine screws. The system will be flown on May 7 at the Friends of Amateur Rocketry site in the Mojave Desert.

Check out the video here.

Club Showcase

This year’s Open House Club Showcase was a rousing success, a big thank you to all the members that could come and talk to the incoming freshmen! We had a triple-booth this year to set up the trailer and (half of) the launch rail with Caution: Flammable. There was a steady stream of people interested in our display, from small children who like to press big red buttons to parents that work in aerospace. There were also several current students interested in joining, so keep an eye out for new faces.

Test Launch and Open House Weekend

This coming weekend is an exciting one! Several of our members will be at the Friends of Amateur Rocketry (FAR) launch site to test the first two rockets: Lexington and Saratoga. Lexington is built for speed to test the avionics system while Saratoga is built to size for the separator test.

Lexington and Saratoga

The members that remain in SLO this weekend will run the CPSS booth at the Open House Club Showcase and the water bottle rocket launch activity. The Club Showcase booth will be as conspicuous as possible; we’re bringing the trailer down so we can set up the launch rail with the large Caution: Flammable rocket.

First HM-7 Test Fire Scheduled

After a very successful dry run of the motor test fire last Saturday, we are prepared to do it for real this Saturday (2/20)! Set up will begin on Friday (2/19) at about 3:30 p.m. We will be taking the trailer down to the prop lab and laying out some cable. Electronics set up will begin Saturday morning at about 9:00 AM.

The maximum occupancy for the control room is 10, limited to those conducting the test. We will have a livestream that will be viewable in the Aero Conference room (41-112) near the propulsion lab. The livestream will be available on YouTube, and will have views both of the motor and the control room.

An email will be sent out with the livestream link and the YouTube playlist on the Media page will be updated.

eWeek Club Showcase

National Engineer’s Week is happening next week, organized by our lovely Engineering Student Council. CPSS will have a booth in the Club Showcase, next Wednesday (2/24) from 10am to 1pm, located in the UU Plaza. Stop by to help talk about the club, or just to say hello!

There are events happening all week long, more information about eWeek can be found on the ESC website here.

Test Rocket & Trailer nearing completion

The first test rocket has been touched up and prepped for paint. Design of the second rocket, to test the parachute deployment system, has already started.

The trailer is nearing the test fire milestone. There is just 4 more tube bends to make and 2 fittings to install. After that, all that needs to be completed is the electrical. We are now waiting on just a few more parts to finally get the trailer fully operational. Over the next week the team will be finishing up the tasks outlined above as well as wiring the interconnects for the sensors. Assuming all goes to plan, next Saturday will be the full systems checkout for the trailer.

Mechanical & Avionics Progress

The mechanical team has been setting up plans and test procedures for the Black powder Initiated Release Device (BIRD). This is the mechanism that splits the rocket so the parachute can be deployed.

The avionics team is working on assembly of the sensor board prototype and has finalized the design of a timer-based parachute backup board. The first test rocket will be testing our avionics at high-speed.
