Here is a picture of my first rocket.

Here is my second rocket.I think you need a nose cone, but not to pointy or to dull.

I also think you need a parachute with out a hole in the top, and I also think the parachute should go under the nose cone. (but make sure the nose cone can come off.) I also suggest you add wings to stable your rocket.
Thank you for looking at my Blogger.

Welcome to my hydro rocket site. In this site, I will be talking about my hydro rocket tests and other things.

Building my rocket
We started making the rocket a few days ago. All of us started off with a normal 300ml soda bottle. The requirements for the bottle rocket was that you needed a recovery system and an 1-3 bottles. I attached my 3 wings to the main body of 1 bottle. Then I cut out 1/2 of a bottle and hot-glued it to bottle #1. Picture enclosed:

The next thing I added to my rocket was my recovery system. I used part of a garbage bag to make a parachute. I attached the parachute to the bottle with some hot-glue and cellar tape. The wings were next. I used a cardboard like substance and cut out 3 identical wings. I connected it with some tape and I was finished with the wings. I didn't add too many wings because it would create a lot of drag. The drag will cause the rocket to go lower than usual. (that's a bad thing)

I could stuff my parachute into the slot in the half tube.
I put the cone on top and I was completely finished with my rocket.
To launch the rockets, I needed the following materials: Water, a air pump, my rocket.
My finished rocket weighed 39 grams total.

Launch #1
For my launch, my rocket went pretty high and my parachute deployed at the end. I figured I needed to have less drag and have the parachute deploy a lot more earlier. That was a problem because if I pull out my parachute it will create more drag. But if I stuff my parachute more in, it will not deploy at all. Finally, I decided to just flatten the parachute against the body of the bottle and put a tennis ball cone on top. that way, the cone will fall off easily and the parachute will deploy. I'm guessing that the rocket will go a tiny bit higher and the parachute will deploy a lot more sooner. Another thing I realized is that the more water there is, the more thrust there is. but since it is heavier, the gravity will drag it down. I put 3/4 of the water I originally put in just in case it was too heavy.

Apogee
Apogee is the point when the item that is being thrown up stops going up and starts going down. when the rocket hits apogee, the parachute will come out and glide back to the land safely (hopefully without killing anybody/anything)

Glossary:
Apogee: a point where a rocket stops going up and starts to go down
Deploy: When a object comes out of a hiding place.

Kaito's Web

Welcome to Kaito's website. This site talks about some fun rocketry.
First, here is a image explaining how a hydro rocket works.

Definitions
Nose Cone: The front part of the rocket that decreases drag(the force that slows or stops a object from moving. In this case it is weight and air friction).
Fins: The part connected to the bottom part of the bottle to keep balance

A normal hydro rocket has a nose cone, main bottle, wings and a recovery system.




Next, here is a picture of my rocket.

Statics:
Name:The trash picker
Height:53cm
Weight:224g/7.9 oz

For best flight results, insert 30.003125oz of water and pump as much air as you can but not exceed 140psi.(an average human can pump up to about 120psi)

Try out the result on this game.

Building a water rocket involves using a launcher and stand, pumping water and air into a soda bottle and launching it outside to see it shoot up from the ground. Put together a water rocket with a demonstration from a science teacher in this free video on science.

Newton's laws

There are 3 laws of Newton. They are:
1. The law of interia. A object will stay at rest unless a unbalanced force reacts on it.
2. F=MA. The greater the mass is the less acceleration is needed
3.Every action has a opposite and equal reactions.

Introduction
Ever heard of astronauts? Amazing adventures in outer space? So, what's behind all this? Rockets. You may think rockets sound intimidating and scientific, which nobody except crazy scientists can make. At least, that's what I used to think. You'll be surprised to hear that nothing's so special about making a rocket. Rockets don't even necessarily need to be powered by fuel (you can do it with water), and most importantly, you can make a rocket yourself! You don't need to be a scientist to launch a rocket.

In this class, we will learn to launch a rocket by using water, ourselves!

Investigation
Hydro Rockets

Rockets are machines with incredible ability to move. So, we will start by investigating 3 of Newton's Laws of Motion.

Newton's First Law of Motion is that an object at rest will remain at rest and an object in motion will remain in motion at constant velocity unless acted upon by an unbalanced force. This law of motion means that something that is not moving will not move unless another force (like a push) does something to it, or acts upon it. Something that is moving will keep moving at the same speed and direction unless some other factors like humans or wind act upon it and change the object's position and velocity. Every time something is moving or staying still, two forces are balanced with each other. For example, when you're sitting on the ground, the force of the ground and the force of gravity are balanced, each force being at a 90 degree angle. If you sit on a slope, though, you start to slide down because the force of the ground at an angle and the two forces are unbalanced. Therefore, you start moving.

Newton's Second Law of Motion is that Force=Mass x Acceleration. This law basically means that the force an object has depends on how heavy it is and what angle it is set on. For example, you may find a rocket blasts up higher if it is lighter and is at an 90 degree angle at blast-off. It also means that if one force is unbalanced, like when the force of the ground is at an angle on a slope, you will start moving. So when you launch a rocket, you need to unbalance the forces to create the thrust to send the rocket into space.

Newton's Third Law of Motion is that for every action there is an equal and opposite reaction. For example, if you jump, you will always fall down again. Falling back to the ground is the reaction of going up. This is again because of the forces. By jumping up, you unbalanced the forces with the thrust created by your legs. Gravity pulls you down again to balance the forces again. To blast off a rocket, you need to create a big thrust to send the rocket high enough to be safe from the pull of gravity.

We need to know about Newton's First Law of Motion because we need to know what forces could affect the movement of a rocket as it flies and how we can avoid these forces. We need to know how to avoid unbalancing forces when controlling a rocket. The reason for investigating Newton's Second Law of Motion is that we need to know what is the best way to blast off our rockets and why rockets are blasted off this way in real life as well. We need to know how to create a thrust to blast off our rocket. We investigated Newton's Third Law of Motion because we need to understand what actions and reactions are involved in a rocket's flight, like blasting off and landing. Also, we need to know how high the rocket need to go before it is safe from the pull of gravity (and how big a thrust we have to create to do this).

Rocket Recovery System:
Every rocket has to have some sort of recovery system to help it stay in one piece when it lands. So, I investigated on recovery systems for rockets.

Here are some types of recovery systems:
Featherweight: This form of recovery is for small rockets. These rockets have blunt noses which helps them fall to the ground after the engine is ejected.

Tumble: The ejection charge pushes the engine backwards until it is stopped by an engine hook , which makes the rocket unstable. The rocket will tumble down and the tumbling will slow down the speed of the rocket.

Parachute: Parachutes are very common for recovery systems. They catch the air and act as an air brake, creating a drag with the air and slowing down the rocket's landing. You have to make sure the parachute is the right size, if the parachute is too small the rocket will fall too fast but it the parachute is over-sized, the rocket will take too long to land.

Streamer: Streamers bring a rocket down slowly because they catch the air, using the same concept as parachutes. You have to check the size of the streamers too, to see if they are the right size for the rocket.

Glider: When a glider rocket reaches apogee in space, the rocket converts into a glider with wings so the rocket glides slowly back to earth. The glider may break through the atmosphere using a booster engine attached to the glider, or the glider may use streamers to drift back to Earth.

Helicopter: This method uses vanes that spin around and help the rocket slow its speed and land safely on Earth.

Investigating Variables:
See below in Extras for link to the rocketry site:

Results from Variable Investigation:
Note: For cone style, please refer to site and count the cone styles from the left
Fixed Variables:
Angle Rocket is launched at (90 degrees)

Launch Number	Cone Style	Nose Weight	Body Weight	Tail Weight	Water (OZ)	Pressure(PSI)	Altitude
1	1	0.3	0.8	0.8	30	140	142.9
2	4	0.3	0.8	0.8	25	140	276.1
3	4	0.3	0.8	0.8	30	140	286.8
4	4	0.3	0.8	0.8	35	140	245.1

Up till now, I found out that the 4th cone was best, as I tried the 1st (bluntest) for my 1st trial, but I found that the sharper cones would work better. This is because a steeper cone wound block the least wind, whilst a blunt cone would block the wind and stop the rocket from going high. I found that it would go highest at around 30 oz of water.

Launch Number	Cone Style	Nose Weight	Body Weight	Tail Weight	Water (oz)	Pressure(PSI)	Altitude
5.	4	0.4	1	1	20	140	299.1
6.	4	0.5	1.5	1	20	140	331.2
7.	4	0.5	2	1.5	25	140	391.1
8.	4	0.6	2.5	2	25	140	422.5
9.	4	0.6	3	2.5	25	140	439.9
10.	4	0.6	3.5	3	25	140	449.1
11.	4	0.6	4	3.5	25	140	605.1
12.	4	0.6	4	3.5	30	140	634.9
13.	4	0.6	4.5	4	30	140	640.2

Launch number 13 was about the highest it could go. So trial 13 is the golden ratio, 30 water : 140 PSI.
Simplified to 3:14.
I think we should pump as much pressure into our rockets as possible (hoping to get it to an ideal amount of 140) and add around 30 oz of water.

My Experiment:

Possible Variables:

Input Variable	Output Variable
Amount of Water and Pressure Used	Height of Rocket at Apogee
Angle at which Rocket is Blasted Off	Time to Apogee
Weight of Rocket	How Long it Takes for Rocket to land from Apogee

Explanation: An apogee is the point where something is at its furthest distance it can be from the orbit of the Earth. Apogees vary with different objects and where they are put. This is because of their different sizes and weights which affects the amount of potential energy they will have to move away from the orbit of the Earth.

Experiment I chose:
The experiment I chose this time was the first one.

Research Question:
How does the amount of water and pressure put in the rocket affect the rocket's height at apogee?


Why:
I chose to do this experiment because I wanted to know how the amount of water and pressure put in the rocket affected how high the rocket could go. From the game I played in my investigation which helped me get close to finding out what was the golden ratio of water to pressure, I knew that the mixture of water and pressure was very important. I wanted to find the real golden ratio for rockets, as real rockets also needed the correct amount of fuel and pressure.

Hypothesis:
My hypothesis is based on some data on the game (refer to investigation). I predict that there should be around 30 oz of water (around 1/2 a bottle) and as much pressure as you can put (ideally up to 140 PSI). Considering that doing it manually could only get the pressure to around 120 PSI, I think you should pump in as much pressure as possible. As it is not certain how much PSI it is possible for us to pump in our rockets, the ratio may not be right

Scientific Reason:
I made this hypothesis because a rocket filled with just water in it won't blast far, as there is no thrust and just fuel. So, I thought that a rocket with as much thrust as possible (as thrust is the main force behind a rocket's ability to flight) and around half a bottle (30 oz) of fuel which is enough to maintain the force of the thrust and at the same time being little enough to hold enough pressure.

The Method (Process):

Materials:

• Water Bottle (1-3)
• Cardboard (for wings)
  
• Garbage Bag (Parachute)
  
• Card Paper (for cone)
• String
• Scotch Tape
• Duct Tape
• Carpet Tape
• Bottle Cap
  

Tools:

• Hot Glue Gun
• Hot Glue
• Scissors
• Computer (research websites)
• Compass
• Pencil
• Ruler
• Eraser
  

Cone:

Using a compass, draw a big circle on a piece of card paper. Cut the circle out with scissors, then cut a line to the center of the circle (cut along the radius). Then overlap the sides of the circle to create a cone, adjusting the size and steepness of the cone yourself.
Tip: Make sure the cone is big enough to fit on your bottle.

Wings:
Draw a wing shape that you would like on a piece of card. Decide how many wings you would like, and draw that number of wings. Cut the wings out and use either hot glue or tape (preferably both) to attach the wings to the rocket.
Tip: Make sure your wings are not to big and not to small so they will both stabilize your rocket and help your rocket go high.




Recovery System:
Decide what recovery system you would like to use (recovery systems are listed above). I used a parachute recovery system. I used a garbage bag, and cut out a square. I folded it into a triangle, then halved the triangle into a smaller triangle. I did this 3 times. For the 4th time, I folded the tip of the triangle to the triangle's base. Then, I cut the triangle into a scalloped shape and cut a hole in the middle. After that, I got string and cut 8 pieces into the same length and placed them an equal distance from each other on my parachute. I used tape to attach them on the parachute.
Tip: Make sure the tape is all the way to the end of the parachute.

Putting the rocket together:
I then hot glued and taped the cone onto my rocket. The wings were already attached. Then, I taped all the strings of the parachute to the rocket with scotch tape, then put a layer of carpet tape over it. I tested my rocket and the recovery system worked. The last step was to put water in the rocket and screw a cap on.

Then, my rocket was completed.

Conclusion:

After our first launch, we got together to discuss what we could do to improve our rockets for their second flights. Some point we could improve were

Nose cone:
Nose cones are necessary to stabilize the rocket and sharper nose cones are better because they won't block the wind.

Rocket Body:
Rocket bodies have to be smooth and without holes (so pressure won't escape). Dents in the bottle actually doesn't matter, because the bottle will expand as we put pressure inside.

Wings:
Wings have to be close to the body, otherwise they will cause drag and affect the height your rocket can go up to.

Parachutes:
Parachutes have to be balanced and able to come out easily. They cause drag so they are good for recovery but may affect the rocket's flight because of the drag it causes as the rocket is blasted off.


After the think tank, I started to improve my rocket. The rocket's nose and body seemed fine. The wings of my rocket were loose, so I attached them again using tape and hot glue. I thought that wings were mainly used for stabilizing rockets, so I didn't change the wings. I found that the rocket that went highest didn't use a parachute as a main recovery system. Though the fact that parachutes cause drag was obvious, I wanted to see if the parachute would cause less drag if I made the parachute strings shorter (as the parachute would catch less air). At my second launch, I found that the length of the parachute didn't really affect the amount of drag the parachute caused.

I think I did well in putting the right amount of water to pressure. The parachute also worked well as a recovery system, because of the drag it created. One more thing that worked well was the nose cone, which didn't affect the rocket's lift off because it wasn't too heavy and was steep.

There are many areas in which I need to improve my rocket. I would need to change the recovery system a lot. This may not mean I would have to get rid of my parachute, I could just put it under the cone so it doesn't cause any drag until it hits apogee and the parachute falls out. Then, the parachute would work for recovery (though maybe not as well as now because it has to knock off the cone first) and wouldn't affect the rocket's flight. One more thing I needed to change was the wings. The wings work well enough as stabilizers, but I would need to make the wings larger like an airplane's so the wings would actually help the rocket go high.

Through this course, I learned how to apply Newton's Laws of Motion to create a rocket that would actually blast off. I got the chance to understand that Newton's Laws weren't so complicated after all, and rockets weren't either. Though my rocket launched pretty high, but I still need to change many parts of the rocket to improve it.

Vinegar Rockets

Vinegar rockets are powered by chemical reactions. Vinegar, an acid, reacts with Alka Seltzer, a base, to perform a reaction that blasts the rocket upwards.
We built our rockets out of feathers, tape, straws, Popsicle sticks, and paper. We had a fuel cell, in which we would pour vinegar in when the rocket was upside down. Then we would take half of an Alka Seltzer tablet and put it in, and close the lid quickly and put the rocket right side up. After a few seconds, the rocket would blast upwards. My rocket went only about two feet up, probably because it had too much weight.

RESULTS FROM LAUNCH

On the launch I think my rocket was pushed down because of the rain. It was raining when I launched my rocket.
The materials to make our rockets were cardboard, bottles, paper, hot glue, tape, rubbish bags, and string.
After we launched we did something called a think tank. Everybody had to brainstorm on how to make their rockets better. Here are some suggestions people made.

CONE
-sharper nose cone
-less weight

PARACHUTE
-balanced
-lower drag

BODY
-smooth
-not dented

WINGS
-not out far
-closer to body

VINEGAR ROCKET RESULTS

Vinegar rockets work and are powered by chemicals. Vinegar a type of acid reacts with Alka Seltzer to push the rocket up into the air.
We made mini rockets. The rockets had to have a fuel cell. You could design your rocket with lots of things. We had Popsicle sticks, feathers, straws, and paper. After we finished designing the rockets we went to test them out.
We had to pour vinegar in the fuel cell, put the Alka Seltzer and put the cap on as quick as we could.
Then the rocket blasted up into the air.

#1Krish Mine had the best recovery system Benjamin's went highest and Aaron's rocket was most successful we couldn't get the results of the angle and feet because our rockets went way to fast and it was our first try. I can guess I can get the scores on our second or third try. All of our rockets went really high and were very successful. Most of us got 120 psi or 115 psi as expected.
#2Krish Today my rocket went really high but unfortunately it crashed on to a fence bar witch made the parachute come out so it landed safely. Max's rocket failed because it's nose cone was to heavy so it launch 3 feet in the air spun around and crashed. Ben's rocket went the highest again but this time its wings fell of and boosted it higher than last time and it split in two as he wanted it to do.
