Who: Middle and High School teams. A team is defined as a 1-2 coaches (teachers, parents, mentors) and a group of 3-5 students. (If a group has more than 5 students, they must apply as two "teams".) While no experience is required, this program is intended as a follow up to a team's participation in TARC.

When: July 13-17. Most days are 9am-5pm but we will start at 10 am on Monday and plan to end at 3pm on Friday.

Where: The camp will be held on the WVU downtown campus in White Hall, home of the Physics and Astronomy Department.

What: Small Satellites for Secondary Students (S4), is a NASA sponsored initiative developed by Sonoma State University in California http://s4.sonoma.edu where youth learn to solder, build atmospheric science and GPS experiments to be launched on a balloon or small rocket. In the process the students learn to build advanced electronic circuits, solder, program a microprocessor, and test the system before using it.

The Team America Rocketry Challenge (TARC) is the nation's largest model rocket competition involving up to 1,000 teams of students http://rocketcontest.org The students design a custom built rocket to carry a raw egg and electronics up to a specific altitude and back in a pre-defined time safely. The program engages students in engineering, physics, and solving real-world-problems.

Our summer camp will blend the two programs with student teams learning to both build a small satellite and a rocket that can carry their payload up to approx. 1,000 ft. and back safely. The camp will be led by Ph.D. scientists, NASA education outreach specialists, and WVU students who build much larger satellites as part of a separate NASA project. Your team will learn about atmospheric sciences, electronics and soldering, programming, rocket design and simulation, 3D design and 3D printing, and more. Your team will build the satellite and rocket and will perform a static weather balloon test on their satellite and will launch their payload aboard their rocket. Finally, your team will analyze the data collected and present their findings to the public.

Cost: Thanks to our generous sponsors, this program is being offered for FREE but teams will have to cover their own travel, meals, and lodging expenses as needed. In addition, there is an optional module of the S4 that our budget cannot afford for the teams that allows live telemetry (radio communication). This optional module costs approx. $100 if you choose to add it onto your payload.

Summer Camp Schedule (tentative):

On Monday we will begin with presentations on atmospheric and space science and provide recommendations for related experiments. Beginning on Monday and carrying on through Wednesday, the teams will be  developing their payload, programming the Arduino for data collection, and will build selected rocket components compatible with TARC guidelines. On Thursday, at the end of the workshop the students will fly their payloads on a rocket or balloon, collect measurements, and begin their work on data analysis. On Friday, students will analyze data and develop presentation which will be delivered immediately after lunch in lecture hall.

WVRock has been supporting a number of school aged groups to implement projects called S4.  S4 is the Small Satellites for Secondary Students (S4).  S4 is a partnership between the Education and Public Outreach group at Sonoma State University, Tripoli Rocketry Association’s AeroPac prefecture and the Endeavour Institute.

The website for S4 can be found here.

In addition to the fun and learning for the students and the photos and articles on this site documenting the progress of some of those teams, several resources have been generated during these projects.

These include a spreadsheet that can be used to analyze data logged on an S4 flight.  The spreadsheet can be found here.

Another resource is a presentation that describes some data analysis done on the data returned from an S4 flight.  The presentation can be found here (with fancy animations :-) ) or here (no animations :-( ).

Data has been collected from a number of flights of S4 payloads mentored by WVRock team members.

This data is shown and can be accessed in the table below:

High Power Rocketry in WV

Click here for the link to our club HPR engine order form (as of 6/21/2015:  hopefully it permanently remains the right link).  Orders will be made periodically as noted at club meetings.

The WV Rocketry Association is committed to supporting its members in obtaining high power rocketry (HPR) certification if they so desire. To this end, our Level 1 Certification chairman, Chris, has filed for and obtained HPR permission from the FAA for our Mylan Park launch site. As the club president and the FAA designated Range Safety Officer (RSO), I have some suggestions for members as they work their way up the HPR ladder.

1. You may want to use a level 1 composite kit (such as the fiberglass Hawk from MadCow) or if you are making your rocket from scratch, over-engineer it using TTW (through the wall) fins, epoxy for all joints, and heavy-duty shock cords to ensure that you don't fail your certification because your rocket was damaged.

2. Have other members double check your design and evaluate your rocket for safety concerns. For example, I learned that my rail button placed at the upper centering ring was positioned a bit too low, and should have been placed at CG. It was an easy fix, but one that I am glad someone pointed out.

3. Use a simulator such as RockSim to validate your rocket's stability and to determine the most appropriate engine. Just like we do with low power rockets, we should ensure our design is as accurate as possible (by weighing components and the final rocket), running simulations with numerous engines, and testing a variety of environmental conditions. Additionally, make certain that your rocket will be leaving our 8' launch rail with sufficient velocity to be stable, that you have adjusted your ejection delay to allow for the optimum ejection (typically at apogee), and you have sufficient size or numbers of parachutes. Here is an example of the simulation data for my quite heavy level 1 rocket. Be prepared to share this data before launching.

4. WV Rock follows the safety guidelines of the NAR with respect to pairing the proper engine with your rocket. While there is no given weight limit for HPR, the NAR Safety Code sates, the rocket max weight should not exceed 1/3 of the total impulse. For rockets under 20 lbs I suggest dividing avg impulse by 25 to determine maximum rocket weight. For example, let's look at my H400: 400/25 yields rocket max weight ~ 16 Lbs. Since my rocket is only 7 pounds, I feel confident that I am safe using this engine. To be safe, you should always look at your engine's thrust curve. A good source of this data is www.thrustcurve.org. I can't recommend enough, that you should read more on this topic when you have time. Visit this great discussion on the Rocketry Forum.

5. And remember, as a club we want to ensure that our launches are both safe and by the book. Anyone can make a mistake so let's follow the NASA motto: "If it's not safe, Say So!"
