Second Term Update #1 (Dec. 22-Feb. 16)-Fredericksburg’s Engineering/Rocket Program

Technically, the fall term didn’t end until January 19, so we have a minor bit of finishing up to do on that semester, but at this point, January  is past and February is better than half through as well.  The spring program is  already building, therefore, we will finish off and shoot straight into the new semester and the new year, as there are big goals and events  for each class group.

This second semester puts the Engineering Program students’ learning to the test as they build rockets and prepare to launch them for Rockets 2018 and their end of class projects. There are still four class groups this semester as freshman through seniors continue course study and  strive  to complete their section of the program.

Both Freshman and Sophomore groups are new for this semester. Last semester’s groups will not return to the program until next fall. This will mean that the progress reports will seem a bit familiar as these new groups will be doing the same projects and learning tasks that last semester’s group did since they too are at the beginning point of the Freshman and Sophomore programs.

Freshmen comprise a group of 13, pictured below. In the front row: Davis Englert, Roan Hagel, Hayle Mayer, Michael Flores, Gerry Balderas, and Daisuke Kyan.

In the back row: Tyler Smedley, Karson Hager, Cade Terry, Sam O’Leary, Kris Ersch, Travis Klokker, and Carlotta Wilkinson.

 This was for fun, and is freshman doing something wacky!

The new Freshmen group is once again testing structures which they are building from cardboard and tape. They watched an engineering video on I-Beams after their first testing session. This enlightened their understanding of bending moments which they applied to their structures.  One of the groups changed their structure by rotating it 90 degrees in order to make it taller than it was wide, which resulted in the structure being the opposite of its original design as well as creating an almost 100% strength increase through the new orientation and heighth.  Mr. Matthes states that this was a “Lesson learned and applied.”

Below, the Freshmen show off their structures.

Currently they are working on their post mission analysis on civil engineering, which is allowing them to  practice technical writing.

The freshmen have a field trip coming up on March 1. They will be visiting UTSA, Center for the Intrepid and Southwest Research Institute, all in San Antonio. A report and pictures will be presented in a future update.

The new sophomore group for this semester has 13 students,  11 pictured below.

Front row: Gabi Moreno, Manuel Enciso, Jarrett Beard, Tyler Malinak, and Jacob Hinterlach. Back row: Tony Martinez, Noah Stotz, Jowad Aysheh, Jack Fox, Troy Kneese, and Jabin Gipson. Not pictured are Jessen Stableford, and Landon Sparrow.

The sophomores are moving through their course studies on a little more fast-track than last semesters class. This has been initiated in order to further their studies in 3D modeling and printing this round so that they achieve a more significant introduction in that area. They are doing well according to Mr. Matthes and are already beginning AutoCAD. In the past weeks they have successfully completed geometry, multi-view drawings, and engineering lettering.

As of January 23, the first semester studies ended for the Juniors, and opened them up to work on their second semester project in which they are now immersed. This project is to design and develop a one pound payload in a Transonic vehicle to be launched on April 26, at Rockets 2018.  This means that their rocket must must be capable of breaking the speed of sound while carrying a one pound payload and remaining under 13,000 feet. The junior group is a large group of 22 students this year so they are unique in that they have been split into two groups, each responsible for their own rocket.

Mr. Matthes had this comment about the two groups, “I am excited to see them working diligently and proudly taking the endeavor as genuine separate groups.  The ownership of their rocket and being different from each other’s groups is already evident.  They have established their problem statements and are feverishly researching with many, many, many unknowns.  As the process goes on their significant dispersion of knowledge and integration with each other slowly but surely migrates to a fully integrated and cohesive design.”

Along with their rockets, the group has another project for the semester. This entails designing and developing a teststand for Estes Motors. These are the small motors used mostly to fly their Generation 1 through 3 rockets. The objective is to create a teststand that will operate using LabVIEW programming to control and monitor ignition, measure thrust, and display and record real-time data to a file.

Seniors are a busy group with four projects still in the works, including Redbird 19, Wind Tunnel, Teststand and Baby Bird Teststand.

On February 1, Redbird 19(RB19) underwent Critical Design Reviews (CDR) with SystemsGo personnel present, and NASA flight engineers participating by Skype. RB19 did well overall.  The Redbird 17 tank is being recycled as part of  the RB19 design and was successfully tested earlier, as shown below, but will be retested on Friday, Feb.16 after which they will be required to provide documentation to SystemsGo. The team is fully immersed in the development of RB19. They have contracted machine shops and begun providing them work. These include Kager Industries, Heartland Enterprises, and SRM. Other necessary parts are in the order process.

Corbin Smajstrla, Sergio Walle, Bryce Erwin, Pierce Vasquez, Evan Knapp, and Harrison Spisak prepare to test the RB17/19 tank.

Wind Tunnel also underwent CDRs  with NASA and SystemsGo on February 1. Unfortunately it was found to have some issues to resolve. According to Mr. Matthes, the group is, “adapting well to the unexpected queries which arose and are close to having them resolved at this point. ”

Teststand has several upcoming events in March. In mid March, they will be conducting cold flow tests in order to verify the students injection system. This tests the flow rate of oxidizer through the system.  Projected live ignition tests have been set for the end of March, and students have been given some solid dates in order to keep them on task to accomplish these.

Baby Bird Teststand is currently on hold. Students have a heavy work load to complete with the other projects. PVC and polypropylene tests will need to be completed on the large Teststand before work can resume on the Baby Bird Teststand.

This article is the Third for the 2017/2018 school year in a series of monthly updates that will follow the Fredericksburg Engineering/Rocket program. This school is a participant of the SystemsGo STEM program. This series of articles is intended to support and encourage students in the program as they share their working status and accomplishments throughout the year in the program. These publications will be available for tags and re-posting.

Rockets 2017-Sunday’s Report-End of Fredericksburg Launches

Sunday is usually a light day at rockets, but not this year. Although we only had 5 schools, there were 16 rockets to launch. Out of those 15 made it to the air. The last one was still in stage 3  with some issues to be fixed, when nature decided we were done for the weekend and a storm rolled in with lightning and rain. Luckily many areas had been packing  things they no longer needed so at least it wasn’t all left to do in the down pour. We all pretty much got soaked anyway, but hey that is Rockets, the weather is always a factor.

We had a total of 81 rockets launched for the weekend and found all but 14 according to recovery captain, Braxton Roemer, seen here quizzing kids and adults on late 80’s rock and pop music during a break in the action.

This gives the recovery group about a 92% recovery rate for the weekend. It could be 93 because Steve found one late yesterday afternoon but was unable to recover it due to severe lightning, but he knows where it is, so either someone will eventually go back for it, the land owner will find it and bring it in, or it will be Team Burow’s first find next year.

Yesterday, I let Steve go solo on recovery, and I joined my daughter, Chelsea, at the pad. I was able to watch first hand all that goes on to get these vehicles in the air. The pad crew makes it look easy, but it’s a little more complicated than what you might think. The original crew of Chelsea Burow, Anissa Kneese,

Josh Hampton, Bryan Heffner,  and Cade Ottmers has had years of practice to get things right. This year they were even training some new recruits in the program, freshman, Troy Kneese, and senior, Jesse Cedillo.. Jesse will be attending Angelo State University in the fall for computer science.

It is a coordinated effort as rockets come to the pad, and they do pictures of the students with the rocket “set” on the rail. Afterwards, the students return to Mission Control so the pad crew can load the rocket properly and safely.

Crew members then attach the match and seat the motor onto the stem assembly, which is a two-part tube fit tightly together, which delivers Nitruos into the tank, and allows Gox to flow over the fuel grain to help with ignition. The stem is fed through the fuel grain and the bell of the motor into the tank of the rocket. This can be difficult as it has to go through very small opens inside the motor and has to be done totally by feel and knowledge of the different motors used in the vehicles,  and the vehicle has to be level while doing this.  It is no small task, but this group makes it look easy, most of  the time. The consensus on the pad is the “L” motors are the worst to seat.  There were quite a few L motors yesterday, but they managed them all. Jesse is seating a rocket in his photo above.

After this is achieved they do systems checks and then raise the rail, ready for launches. This is referred to as “going vertical”.

Pad members work in small groups throughout the pad attempting to load all 6 rails if enough vehicles are available. Occasionally it takes the whole crew at once to raise the rails on some of the larger or more complicated rockets.

When launching begins and a vehicle is “Armed” (this is basically the altimeter is turned on and verified to be working) then all must clear the pad except the two members working to launch a particular rocket. Next they go for fill, after which the launch count down sequence is initiated. At this point the they run for cover in the bunkers.

After the rocket has cleared the pad everyone watches skyward and hopes for a good flight and successful deployment of  the recovery system. Once the vehicle is confirmed down or determined to be too far away and has no chance of coming down near the pad, then the  crew is back out to work the next one.

If a rocket fails to leave the rail, then the pad crew determines if it is something they can fix on the rail or if it has to be unloaded and returned to Stage 3. At which point the students and technicians will re-evaluate and determine if they can fix the vehicle for another attempt at launch, or abort.

The crew members are all past students of the program and know quite well what to look for if a rocket fails to launch. Most of the time it is minor things that can be fixed on the spot, but not always. Another factor that will cause a delay on the pad is empty fuel tanks.  At that point they move to another rail while tanks are replaced.

This is just a small synopsis of what they do and not nearly all of their skills. They are an accomplished group and I really enjoyed my time there on Sunday.  I helped where I could with several rockets, took pictures of students and their rockets, and the launches, and assisted in tearing down the 1 lb/1 ml rails and other aspects of the pad that were no longer needed as we were awaiting the  arrival of the final Transonic launches.

Since most of you know that I am in Recovery out at rockets each year, I will let you know I didn’t shirk my duties completely. I recovered a nose cone, a rocket bottom ring, and two body tube shrapnel pieces from two different launches while working at the pad.

This marks the end of another great year of rockets for the smaller level vehicles. Rockets 2017 has only the Goddard level launches left which are coming up in late June. There is a fairly strong date, but I won’t be posting that until closer to time since they can still be subject to change at the Army’s need. I will keep everyone posted on that as information is available. Good luck to all those schools and safe travels when you go there. For more information as usual check their website at www.systemsgo.org .

I will be posting a final update on how the Fredericksburg STEM Academy’s junior class rocket did this past Thursday at Willow City. They are evaluating their data and then we will have more details.

The following is a link to the album of pictures from Sunday’s launch. Have a look, you and your school rocket just might be in there.
