Day 8 (3/29)

What was common with all of our launches was that all the rockets were able to launch. Another thing that was common was that all of the rockets were angled into the wind so they would go straight. A final thing that was common was that lots of the rockets corkscrewed or at least turned a little.

Some of the launches failed because of the electrical pyrotechnics used for the igniters, they were cheap so they didn’t always work. Another reason some of the launches failed was because the alligator clips or other wired were crossed or because the wires were touching the metal blast shields which created a short circuit

We used each of the steps of the scientific method in our rocket building/launching process in this way: We observed (in the launching process) that the wind was blowing fairly hard so we angled the rockets into the wind. We asked the question (in the building process), What type of fins will work best? We created an educated guess (hypothesis) of which fins would work best by getting some inside information from an expert (Mr. Davis). We conducted and experiment (launched the rockets) to see which types of fins worked best. Then we created a conclusion; we are not sure which fins work the best because there may have been an error in the launch system (the launch pole was tilted) and the data has not been fully analyzed.

Day 7 (3/27)

400000 pounds of payload will take 800000000 pounds of fuel to lift it (400000*2000)

Rocketry Rules:
1.Materials - I will use only lightweight, non-metal parts for the nose, body, and fins of my rocket.
2.Motors - I will use only certified, commercially-made model rocket motors, and will not tamper with these motors or use then for any purposes except those recommended by the manufacturer.
3.Ignition System - I will launch my rockets with an electrical launch system and electrical motor ignites
4.Launch Safety - I will use a countdown before launch, and will ensure that everyone is paying attention and is a safe distance of at least 15 feet away when I launch rockets with D motors of smaller, and 30 feet when I launch larger rockets.
5.Misfires - If my rocket does not launch when I press the button of my electrical launch system, I will remove the launcher's safety interlock or disconnect its battery before allowing anyone to approach the rocket.
6.Launcher - I will launch my rocket from a launch rod, tower, or rail to ensure that the rocker flies nearly straight up. I will use a blast deflector to prevent the motor's exhaust from hitting the ground, and I will cap the end of my launch rod when it is not in use.
7.Size - If my model rocket weights more than one pound (453 grams) at liftoff or has more power than a single G motor, I will check and comply with Federal Aviation Administration regulations before flying.
8.Flight Safety - I will not launch my rocket at targets or near airplanes, and will not put any flammable or explosive payload in my rocket.
9.Launch Site - I will launch my rocket outdoors, in an open area and in safe weather conditions, (*LITTLE OR NO WIND) and will ensure that there is no dry grass close to the launch pad (*OR IN THE FLYING FIELD).
10.Recovery System - I will use a recovery system such as a streamer of parachute in my rocket so that it returns safely and undamaged and can be flown again, and I will only use flame-resistant or fireproof recovery system wadding in my rocket.
11.Recovery Safety - I will not attempt to recover my rocket from power lines, tall trees, or other dangerous places.

*ADDITIONAL ESTES REQUIREMENTS

Day 6 (3/26)

The difference between the true and magnetic north is that true north is the direction of earth's North Pole, and magnetic north is the direction of earth's Magnetic Pole.

The attitude gyro it a gyroscope that shows if and how much the plane is banking.

Airfoil- An airfoil is any shape designed to "cut" through the air.

35.5 statute miles are equal to 30.9 nautical miles.

150 statute miles are equal to 130.4 nautical miles.

Day 5 (3/23)

5000 Nautical miles is equal to 5750 statitute miles.
What I like about this class is that even though we are learning lots of stuff we are still having a lot of fun while doing it. I find that learning things in ways that are more fun makes the concepts sink in more deeply and easily than if you are learning it boringly. I learned a lot about the aerodynamic structure of a wing in the class so far, I learned about the Bernoulli effect, the Newtonian theory, and the Circulation effect and how they all help (or explain how) the plane can fly. I also learned some simple navigational concepts, such as, latitude and longitude, datum, along with some SAR tactics. I don't want to change anything, because everything is great and I am having a load of fun.

Day 4 (3/22)

Occam's Razor is "Whenever one can remove the impossible, what remains, however unlikely, [leads to] the truth."
Ruben H. Fleet was important because he started the first air mail program, he founded a company (Consolidated Aircraft) and built several of the most famous aircraft of WWII, including the B-24 Liberator and PBY Catalina.
A Datum is a green hourglass mark that shows the last or current known position of the search target.
The red baron's plane was red because he wanted other pilots to be intimidated, since he was on e of the greatest pilots in WWI just the red plane could scare pilots out of fighting him.

Day 3 (3/21)

The Bernoulli effect is where the wing is moving through the air and some of the air is forced to go over the top of the wing and speed up, because free air doesn't compress so it speeds up to move over the (bigger) top of the wing. Higher wind speeds means that there is less air pressure, because fast moving air can only exert pressure in the direction it is moving in. The air that moves under the wing moves slower and slower air has a higher pressure, so it lifts the wing up.

The Newtonian effect is where, due to the angle of attack the air skips off of the bottom of the wing and therefor pushing it up.

The Circulation theory is a combo of the two. The air bounces off of the bottom of the wing and some of it is forced in front of the wing.

Yaw- Nose left/right
Pitch-Nose up/down
Roll-Wings bank left/right
Dihedral-The slight V shape of wings that helps the plane balance
Static-Staying the same
Dynamic-Changing
Aerodynamic-Able to cut though the air

Day 2 (3/20)

What I improved on my plane was that I made a new wing for it that was based upon a glider wing design. It was sort of like a backward delta wing. It gave the plane a lot more lift, but there was a downside to that as well, there was too much lift, so the plane would try to do a loop the loop and hit the ceiling. I also added elevators on the horizontal stabilizers, but one of them broke off and then the plane started turning to the right. So when I did the test the plane veered off to the right and hit the wall. My first flight went 5.8 meters and my second flight (with the moded plane) went 4.5 meters.

We did the scientific method in class by doing all of the five steps. We did observation because we watched Mr. Davis fly some planes that worked well. We asked the question, How can I make the plane better? Then we (or most of us) formed a hypothesis, something like: My plane will now fly farther because of the bigger wings, or Now my plane is lighter so it will fly better. The experiment was to launch all of the standard fliers (on a yardstick catapult, so the results would be unaffected by different throws) and average the distances, then to launch all of the moded planes (in the same fashion) and average the flights. Then we analyzed the data and came to the conclusion that the moded planes did not fly as far as the standard planes, in fact only two people’s planes flew better than their standard versions.

Day 1 (3/19)

My definition of flight is when a craft uses the air to stay aloft for more than a short amount of time and also can move through the air. (So basically something that flies is like a bird, it may not have the same shape of design principals but it can still stay airborne).

The four forces of flight are lift, drag, gravity, and thrust. Lift keeps the plane up in the air, drag allows the plane to turn but also slows down the plane, gravity pulls the plane back down to earth, and trust propels the plane forward and helps create lift.

Anything Paragraph

I'm writing a paragraph about anything I want to, so I think I will write it about what ever I want. HA!
