Rocket
Our rocket is an 87 inch rocket with a fiberglass nosecone, quantum booster tubes, and fiberglass fins. There are three sections in our rocket:1 - The booster tube; the part that houses the motor, holds the fins, and has the drogue parachute.
2 - The recovery/avionics bay; the part that houses the ejection charges for the rocket, the altimeters, and the main parachute.
3 - The payload bay; which holds our scientific experiment.
Payload
Objective:
Our objective was to study and observe the effects of rocket flight onthree different cases of blood pressure in veins. This included G-force,
atmospheric pressure changes, apogee, and turbulence in the rocket cabin
on the descent.
Tools:
Setup
We have tubing coming from the pump. The pump applies force on the IV solution through the tube, circulating it. The system ran throughout the flight.There are two pressure monitors, one for the blood pressure recording results of the pressure changes at the different stages of the rocket flight, and the other for the atmospheric pressure during the flight. The blood pressure was recorded during the entire flight, and each data sample will be timestamped.
There is also be a pressure monitor in the payload chamber recording the chamber’s pressure. After the rocket flies past 1000ft., the pressure will be only affected by atmospheric pressure, since G-force no longer affects the pressure.
Here is a brief sketch of our design:
Results
Our rocket launched on the 17th of April 2011 and we did get some results from our sensor. Here are some graphs of the data outputted by the sensors. The first graph is the first 139 seconds of flight, and the second graph is from 139 – 200 seconds. The rocket landed at 159 seconds.
Here is the atmospheric pressure change during the first 100 seconds of the flight.
By comparing the blood pressure graphs vs. the altimeter graph, it can be assumed that the atmospheric pressure change changes the blood pressure very little. However, G-forces did change our blood pressure, as seen in the large peak at the beginning of the first graph. We found that this correlates to our launch and motor burnout by looking at the USTREAM video online and the altimeter data. We had expected the pressure in the beginning to go down, but instead, it went up. Further testing would be required to discover why. We are not able to explain the other peaks in the graphs. However, the rocket, according to the USTREAM video, landed at 159 seconds. This is where another small peak starts on the second graph. This peak may have been caused by the shock of the landing.
Education
Completed
4-H Forensics
At a local 4-H Forensics competition, we gave a presentation on how to Build a High-Power Rocket. We won 1st place in the competition.
5 kids were present in the audience watching. The subject was Building a High Power Rocket Powerpoint with slides and detailed photos from our rocket-building experience last year. We discussed rockets for schools, rocket components, other materials, body tubes, motor tube construction, filling spirals, fins, payload tube and coupler, nosecone, rail buttons and pressure hole, painting, and launch, as well as a suggestion NOT to start with high power rocketry, and, instead, to start with a low power rocket kit.
Answered questions:
Question: What was the hardest part of building the rocket?
Answer: We also had to build a payload along with the rocket. That was the hardest part.
It was a good practice for a presentation that we can use at any future presentation opportunity. For example, we can offer to present at other 4-H club meetings.
Zion Lutheran School
We had a presentation with the 7th and 8th graders at Zion Lutheran School in Wayside.
23 students were present.
We talked about Rockets for Schools, building the rocket like at the 4-H Forensics competition, and SLI. We then set up some paper-rocket building stations at the school gym. We had the kids build their own paper rockets with the instructions, and have them launched off of our paper rocket launchers. We had them try to get their rocket into a basket on the other side of the gym, and if it didn't, change their rocket so that it might. We can have our presentation at other schools.
4-H Demonstration Event
St. Francis Xavier School
We presented to 5th graders at the St. Francis Xavier School in Manitowoc.
18 students were present. We talked about Rockets for Schools, rocket components, building model high-powered rockets, and SLI. We then set up some paper-rocket building stations outside. We had the kids build their own paper rockets with the instructions, and have them launched off of our paper rocket launchers. We had a contest to see whose rocket went highest because of good construction. We also had the students guess what certain components of the rocket were for.
