#TeammateTuesday: Eric Z.

Our next #teammatetuesday features Eric Z. from Columbia, SC. Eric was inspired to become an aerospace engineering after witnessing a space shuttle launch the age of 12.  He joined the SLI team due to his continuing interest in rocketry and he thought it was the coolest senior design project. Eric is the Computer Aided Drawing lead for the launch vehicle. In this role, Eric oversees all of the 3D drawings for launch vehicle and makes sure they are kept up to date as the design is adjusted. He plans pursue a career in the space industry after he graduates in May. Eric is an Eagle Scout and a state champion in rugby, as well as a national champion in JRTOTC. A sample of his work (the fin can for the rocket) is shown below.Fin Can.PNG

Cub Scout STEAM Outreach

The Charger Rocket works team stayed busy over the winter holidays. In addition to flying our sub-scale rocket and working on our CDR, we assisted with Cub Scout STEAM Camp Space and Robotics Days. For Space Day, we started with a discussion of how rockets work and their important parts, then assembled model rockets to launch the next afternoon. Afterwards, the campers built model space habitats out of Lego. They included necessary features such as rovers, living spaces, and waste disposal as well as facilities to recreate some of the creature comforts here on Earth.


Next, the campers discussed space suits and what astronauts need to survive outside of a ship or habitat. They then designed their own suits out of cardboard, plastic bags, and other recycled materials.


After the space suit fashion show, it was time to launch the rockets built earlier in the day. Most had a successful flight, but there were a few that failed to properly deploy their recovery systems.


For team member and Eagle Scout Nathanial L., it was a great chance to give back to an organization he owes so much to. “As a Scout, I learned a great deal about becoming a responsible, committed individual. These character traits are essential to being a good engineer, and I hope to inspire and teach future engineers through Scouting,” he says. At the beginning of the day, it was shared how many astronauts were Scouts. The skills learned in Scouting are similar to those needed by astronauts.

For Robotics Day, the campers programmed and played with different types of robots. Each type of robot had a few tasks it did well. The campers also discussed robots from video clips and articles, and shared what kind of robots they would design. They built scribble bots out of motors and batteries to take home.

Subscale Launch 12/16

The team arrived to the field in Childersburg, AL around 10:00 am and immediately started following our procedures to prepare the rocket for launch.IMG_3803IMG_3804IMG_3805IMG_3824Our project manager made sure our parachute wasn’t tangled.IMG_3838IMG_3848IMG_3852IMG_3854IMG_3867IMG_3868First flight of the day!IMG_3920IMG_3923IMG_3924IMG_3925IMG_3930IMG_3933IMG_3934IMG_3940IMG_3951IMG_3959IMG_3961After a successful launch and recovery, the team quickly turned the rocket around to launch again.IMG_4025IMG_4028IMG_4029IMG_4036IMG_4037IMG_4039IMG_4042IMG_4045The subscale reached a max altitude of over 3100 feet. Analysis of the flight data is underway!

#TeamateTuesday: Bao H

Bao comes to us from Ho Chi Mihn City, Vietnam. An aerospace engineering major, Bao is the Safety Officer on the team. He is in charge of leading procedure development and hazard analysis and mitigation (and reminding us to wear safety glasses!) Bao joined the SLI team due to his interest in flying systems and his desire to learn rocketry. Bao is excited to participate in the SLI competition and recently earned his L1 Tripoli certification. Bao plans to attend graduate school at UAH after he finishes with SLI. He is also a firm believer that pizza and pineapple both taste good, but not together. This has been the topic of heated debate for late night work sessions, which Bao usually attends.img_3417.jpg

Subscale Rocket Building

Before we launched our subscale rocket, Dave, we had to assemble it. Once each part was manufactured, we marked hole locations to ensure the rocket fit together each time it was assembled.

We also had to make sure that our parts were smooth and fit well in the rocket.


We used the 3-D printer in our UAH Machine Shop to printer our fairing, avionics bay, fin can, and nose cone.


Finally, we could begin the assembly process.
