Day 59-Rockets at WSMR -Launch Day 1-Update

Monday was another long day for the SystemsGo team, students from Marble Falls and Anahuac High Schools, and WSMR officials as they commenced the first day of tests.  Start time on the range at 0400 was with no electricity due to lightning strikes the evening before, but this was quickly corrected.

The Fill and Fire System completed set up with the addition of the Comm Readout Displays which allow the bunk house and the pad to see a digital readout of the temperature,  pressure, and weight for the vehicle on the pad during the launch preparation sequences. The full system was tested and minor glitches addressed which brought it to 100% working and readiness. Throughout the day the system was reported to work great and continued at 100%.

Marble Falls was originally scheduled to test a 0830, instead it made it to the pad at around 1200. The vehicle passed its final fill and fire tests and went vertical around 1230. The survey team set the angel at 85 degrees with an azimuth of 355. Six Nitrous bottles were loaded into the tank. At this point it almost over pressured and began to release venting liquid instead of gas. At 175 lbs and 900 PSI  the vehicle was determined ready for launch. Switches were good, and flame was good, but the injector failed to open and the rocket went into a still fire burn on the pad, continuing to burn for four minutes, until the bottom began leaking the nitrous.

Army rules forbid any contact during this time and for 30 minutes after the fire burned out. At that time the Oxidizer crew was allowed to approach and evaluate the vehicle. The rocket was too hot too touch delaying removal of it from the pad for another hour.

Minor damages were reported to the launch rail and trailer, but nothing that would affect or delay any future launches at this time. Instead it was just enough to give Captain Garrett something to do over the summer again.

At approximately 1400 Anahuac’s vehicle was brought to the pad and cleared for launch. At fill, one and a half bottles were loaded into the tank at which time it began leaking out from a vehicle malfunction, and Anahuac had to be scratched.

This concluded the tests for the day, setting today’s successful launch rate at zero. Any school that actually makes it this far is still a success for the simple fact that they attempted a launch of a vehicle of this size. They still have post analysis to do and challenges to over come to prevent these outcomes in the future.

Mother nature was reported to have attended the tests today as well and thrown her own challenges into the range for the crew to overcome, as well as find some humor in once they had passed. First a large dirt devil spawned right on top of the range and attempted to steal one of the large staging tents, causing a commotion as individuals scrambled after and reset it. Later, two birds were fighting on a transformer out by the pad, when a loud pop resounded, right after which one bird fell to the ground while the other made its escape and the power at the pad went down. Luckily they were using generators so this did not affect the pad and they continued as it was being fixed.

The crew spent fourteen hours at the range today, with an 8 hour launch window. Tomorrow they begin their day at 0900 with a shortened 6 hour launch window due to some other military tests scheduled for that morning early. Union Grove High School will be first followed by Booker T Washington High School. Both rockets are reported to be at 100% and waiting.

That concludes Monday’s WSMR Rocket update.

Day 56 – Rockets at White Sands Missile Range

While the more public focus of SystemsGo Rockets 2015, the launches of the Tsiolkovsky (1 pound/1 mile), and Oberth (Transonic) rockets may have come to a close for this year, the program has not finished for the year. The SystemsGo Rocket program now transitions to Goddard level rockets. These rockets and their subsequent launches at WSMR (White Sands Missile Range) are the culmination of all the skills the students have learned  throughout their years in the STEM program. This is their final senior project for those schools that participate in this level of the SystemsGo program.

By now these students have spent a minimum of 2 years, some three, and as the program expands with new STEM requirements in education, as many as four years will have been spent following and learning in this system of education. They have spent countless hours both in and out of class.

The year is divided by semester into two project bases. The first semester deals with early design phases including payload, performance, and vehicle configuration. Once the payload and an initial vehicle design concept have been developed the student project team begins developing a flight profile. This is used to predict what will happen during testing, including vehicle stresses and flight dynamics. By semester’s end, a test vehicle configuration should be fairly realized.

Semester two is the culmination of everything the students have learned in the first semester, and the continuation of using life and work skills to manufacture their test vehicle, perform a test and analyze their test vehicle findings. Success for this project is determined by two things.

1. Was the rocket finished by the scheduled date and delivered to the pad for testing?

2. How was the rocket’s flight performance in relation to its design parameters?

This translates to the students manufacturing a rocket from scratch; usually weighing in at between 250 to 450 lbs; to reach high altitudes and Mach 3 to Mach 4 velocities. This project is what all the previous years’ effort have been building up.

At this point, in order to achieve their goal, one large working team, divides into several smaller teams with designated goals for each part of design and development for the vehicles’ creation, propulsion, and testing. These component teams include:

Nose cone

Avionics/payload

Oxidizer tank

Injection

Fuel Grain

Nozzle

Engine case/forward skirt/fins

Each team first creates a workable timeline and then begins researching all necessities and questions concerning their team’s component. Questions they encounter may include function, simplicity, mass, etc. Students present their findings in the form of mathematical calculations for their design and these are reviewed and critiqued by aerospace professionals. Students must find their own solutions to any problems presented to them by these professionals.  Once a mathematical argument and a design drawing have been created, the team starts another research phase into the materials to build their component. In this phase students must be able to show critical thinking skills while studying different materials and their costs, safety, ease with which to work and whether they can be ordered in within time constraints. After the design is developed and reviewed and the correct materials determined, a Critical Design Review (CDR) is presented to the other teams for acceptance. If approved the team then begins development of the component, acquiring materials and enlisting any help they may need from local industry. If it is declined then the team redesigns it until the component is accepted by the entire group. If the original time line is kept each team’s component will be finished by the deadline. To ensure this each team must undergo a Flight Readiness Review (FRR) showing that their project is 100% ready. Once all components have demonstrated a 100% readiness, then the complete vehicle can be constructed  into a full standing rocket. SystemsGo calls this their “‘all-up’ configuration.” At this point, Standard Operating Procedures (SOP) must be developed and adhered to in order to test their rocket. To do this, students must be in communication with the launch facility, create support teams, and prepare necessary paperwork. Final preparations for the launch also include students working together to make sure the components are all prepped and ready, or working in mission control, meteorology, safety and other areas needed at the launch.

Next the rocket is tested and hopefully undergoes a successful launch. After this a Post Mission Analysis is done to evaluate the complete performance of the vehicle. This marks the end of the of the  program.

The knowledge base the students acquire through this program include: as quoted from the SystemsGo website: design and development, critical thinking, fabrication/machining, problem solving, teamwork, communication, analysis/application, documentation,  presentation, research, time/project management, budgets/purchasing, public relations, and computer skills in RockSim, Excel, Microsoft Word and PowerPoint.

These rockets which usually stand between 20 to 25 feet and range from 8 to 10 inches in diameter are an amazing sight to behold if for no other reason than that they are built by high school students, not professional aerospace engineers. They are built by the future of these industries. Many of these students go on to become engineers, machinists, scientists, physicists, mathematicians, and countless other business professionals. This STEM based program teaches them skills they can apply to life and use to continue into their future learning and job markets.  If you have a student in the STEM program at your school who is excited about what they are doing, take interest, get involved and don’t miss the chance to see what they is happening first hand whenever possible. You are watching the future in something we can all be proud. These students are doing truly amazing things.

This article was intended to be a synopsis of the program in hopes that others may take interest and pay attention to what these students are achieving, so that more schools might implement the program for their students. It is well worth the time an effort involved. What better way to learn than to have the students apply what they are learning first hand and achieve a workable goal. The teacher is the instructor, guide, mentor, and timeline manager, but  the  project’s success or failure is in the students’ hands. They are the project managers that do all that is needed to see that this vehicle makes it to the pad and then into the sky. If your student makes it to this level, don’t miss out, you want to see this monster fly. It is a proud moment you won’t forget, and even more importantly, neither will your student. Their future begins here, don’t miss out on the chance to support their dreams.

I hope I have done the program justice, as I tried to describe it in a way that might be understood by all and draw some interest. My husband Steve, said I should just say, “Kids make really bad a$$ rockets and launch them at White Sands Missile Range.”

Well he has a point and that is the just of it, but it is really a whole lot more than that!

Tune again tomorrow for a schedule of the upcoming launches at White Sands Missile Range this week, and hopefully some daily high lights from the group.

Day 15-The Launch Pad Crew

Today’s blog is about the crew that runs the actual launch pad for the rocket tests. Most of this group is made up of past students that have gone through the SystemsGo program. They are all pursuing engineering careers at their respective universities. All three completed the program at Fredericksburg High School and ended that time there with a successful Goddard level rocket launch at White Sands Missile Range (WSMR).

Being at the pad, is both exciting and dangerous. Personnel here have the responsibility of loading each vehicle onto the rail, going for fill and relaying the go ahead for ignition.

These future engineers come back each year for several reasons. First and foremost they all enjoy what they are doing out there. Second as engineering students in college, this is a hands on opportunity to work in the field and have this addition for their resume`s. Lastly, they are big proponents of the program, and know firsthand what it has done for them and what it can do for students in the future so they want to help out and keep the program running, so that others will continue to have this opportunity. Most if not all of this crew will be traveling to WSMR later this summer to help run the launch of the Goddard level rockets being tested there as well.

These students include: Cade Ottmers, Annisa Kneese, and Chelsea Burow.

This year, Annisa brought a group of engineering students from Texas A&M to observe the program here first hand, and  though I do not have all their names,  I wanted to mention them because they also helped at the pad on Sunday. This gave them firsthand experience in what is being done.

Andrew Matthes, the program instructor at FHS, and retired teacher, Ned Butler, also provided assistance, instruction, and monitored safety at the pad throughout the weekend. They help insure that all procedures and checklists are followed to provide the most successful test of each vehicle.

The program wouldn’t be as successful as it is without the willingness and effort of the individuals at the pad. Each vehicle is literally in their hands in the last few moments before the test.  They check for any final issues that might prevent launch, and stand by with each vehicle as it begins fill and watching for signs that the rocket is a go for launch. For this I applaud their hard work and resilience. This year alone they had a 100% launch rate, meaning that every vehicle that made it through the Stages 1, 2, and  3 and down to the pad, left the rail at launch. Congratulations Launch Pad Crew!

Thank each one of you for all you do and are willing to do to help each vehicle complete its launch. You are an outstanding bunch, and so detrimental to the program’s success on launch days.

In The Beginning

This is basically a writer’s blog, with the main writer being of course, me. It will be a way to share writing and keep myself busy doing some form of writing, hopefully every day. At some times it will be things I have written and want to share. At other times, it will be interesting things I am involved in that I want to share with you, whomever you may be that decide you want to read my words of wisdom, or perhaps not. You see, there I go, sometimes things may be really serious, other times they may be completely goofy and off the wall.

I will give you a little preview of next week’s blogs. I do intend to share some highlights from the SystemsGo Fredericksburg Rocket Launches in Willow City. If I can figure this out and add pictures I will try to do that too. I am helping with recovery again this year, and am super excited to help. It is always a blast. There will also be a live video link so you can come out and watch in person or from the safety of your computer at home.

If you have never heard of this, it is part of the STEM program now available in area high schools. STEM stands for Science, Technology, Engineering, and Math and is designed to start our children in future careers in all these now heavily technical fields. If you listen to the radio you may have heard ads by the US Navy backing this program (STEM), they are highly interested in receiving candidates that have had prior training and education in this program because our military has become very hi tech as well. This program benefits our youth whether going the college and job route or the military route. If you have a junior high or high school age student encourage them to get into the STEM program at their school. If your school has not yet developed a program, encourage them to do so, because these are the big jobs of the future.

Skills learned in the different areas required by STEM and programs like the rocket program and other programs in STEM encompass more than just the four core classes you hear in the name STEM. Students in these programs, learn skills in mechanics, welding, PlasmaCAM, wood working, and other hands on building skills. They learn grant writing and proposals in order to fund their projects. They learn business skills, presentation and marketing, research and analysis, design and development, materials, inventory, and product ordering and so much more. Most of all they learn critical thinking and how to work both on their own and as a part of a larger group that each contributes a vital piece to their project in order to have it completed and successful.

I personally have had a nephew, niece and 2 daughters that have gone through our local program and they have all benefited from it greatly. My nephew, is top management at SpaceX in McGregor, TX, my niece is in Avionics Electronics  in the US Navy, one daughter is an Aviation Structural Mechanic for helicopters in the US Navy, and my older daughter is studying Electrical Engineering at Texas Tech University.

This week several of our program graduates, the SYSTEMSGO coordinators, and several volunteers are headed to Clute down by Lake Jackson, TX to help several Houston area schools launch their rockets. Next week the team and many more volunteers will be here at Hillview Ranch in Willow City, TX to help over 30 Texas high schools attempt to launch over 80 more rockets. It is well worth the time to watch, not only to see the rockets fly, but to see the joy in the students’ faces as their project of 1-2 years in the making, comes to a successful end. To clarify, even if the rocket doesn’t fly, it is still a success in all that the students learned to get it here, and in what they will continue to learn from analyzing what went wrong that prevented it’s flight. The hard work that is done to get them to this point is the true success and is a catalyst that will help launch them into their future careers.

Ok maybe I did know what  to write about today.

Houston launches are this weekend, May 9 & 10.

Fredericksburg launches are next week, May 14-17. Come watch them or watch online at the SystemsGo web page. Directions and details are also on this website.
