Introduction
Combustion reactions consist of three main things that are put together to depict something called a combustion triangle: heat, fuel and oxygen, in the experiment we conducted we used the matches that were provided in the lab, for the fuel we used Acetylene (C₂H₂) and the third component is Oxygen gas (O₂). Moreover such reactions must be conducted under great care because of the combustions that occurs, therefore any person interacting with such reactions should be completely aware of the dangers that accompany such experiments

Trail 3) the third rocket had a 100% Acetylene (C₂H₂) in it and 0% Oxygen gas (O₂), much like the second rocket this rocket did not launch but it’s crucial to mention that it did release a partially intimidating sound and a dark cloud emerged once we squeezed the pipet.
Trail 4) the fourth rocket was filled in an equal manner of 50% Oxygen gas (O₂) and 50% Acetylene (C₂H₂) and in this trail the rocket covered the distance of 2.5m.
Trail 5) the fifth rocket was the inverse of the first rocket as we filled it with 75% Acetylene (C₂H₂) and 25% Oxygen gas (O₂), unfortunately this rocket did ignite but it only landed next to the launch pad.
Trail 6) the last rocket was a bit different from our previous rockets as we tried a different proportion for this one, where we filled it with 60% Oxygen gas (O₂) and 40% Acetylene (C₂H₂), this rocket did not launch but it did explode and a the explosion was so strong the pipet was destroyed, an extremely loud noise was heard and this was truly the biggest impact we have had through all our
...After Sonny brought home the win, all of Coalwood was happy for him and the BCMA. In celebration, the BCMA decided to make 6 more rockets and fire them off all day long after graduation. They advertised the launch all over town, and people came from all over to watch. The final rocket that they launched for the day was actually fired off by Homer Hickam Sr., Sonny’s father. Considering that his dad had never been supportive of his rockets, Sonny was honored and grateful to have his dad pull the string for the last rocket ever launched by the BCMA. Auk XXXI was 6 ½ feet long, and 2 ¼ inches in diameter. The rocket shot off into the air, becoming smaller and smaller as the crowd stood in awe watching the 6ft rocket become a tiny dot in the sky. Auk XXXI flew over 31,000ft, just under 6 miles, making it the most successful and memorable rocket the BCMA ever launched.
Combustion is a rapid, continuous reaction that usually takes place in the gas phase. Wood is an organic compound primarily comprised of cellulose. For wood, the phase change from a solid to gas is almost instantaneous as combustion occurs (Coleman, et al. 95). Ignition occurs when an outside source is no longer needed to sustain combustion (Coleman, et al. 87).
Homer is amazed on how mankind, as a whole, launched an object into space and put it into orbit around Earth. Many people, in the 50’s and still to this day, can’t comprehend how accuracy is important when launching a rocket. According to NASA, rocket launches have to launch in a certain time period or they won’t go into orbit, potentially co...
John wanted to go to space again same as Bob. So they had a plan to go to space again. They fixed their spaceship’s engines, windows and they filled the petrol tank with fuel. They also cleaned the spaceship and it looked like new. Bob made an experiment to make the powerful engine even more powerful. John added a massive booster which is seven tons. He also adds a jet engine which is faster than the other one. The two boys helped each other to make their spaceship better.

From working out how much fuel has been used I can work out how much
At the beginning of this assignment, both McKenna and I had no idea how to build a bottle rocket. After visiting several websites and researching multiple ways of making it, we settled on a single bottle rocket with a rounded nose cone and three fins. This was chosen because it was the easiest model to create and that meant a less likely chance of messing up. We were just concerned with getting the rocket into the air. The rounded nose cone was created by layering paper and then rolling it and folding it in way that fit around the bottle and was not a completely pointed cone. We then layered it with duct tape to keep it somewhat stable. Before attaching it to the bottle, we put five fishing weights in the top and then stuffed the remaining space with paper. After that, an outrageous amount of duct tape was used to put the nose cone in place. Following that we started to work on the fins. There were two different fin shapes that we tried. The first was a long skinny triangle. The second type was a rather wide triangle with two of the corners chopped off a bit. Each of them was cut out of cardboard and was then covered in duct tape in order to keep the cardboard from getting wet and
...derwent varies improvements, which involved raising the heaters in the oxygen tanks from 28 to 65 volts DC. The oxygen tanks thermostatic witches on the heaters weren’t modified to withstand the changes it underwent. On the final test of the launching pad the heaters were said to be on were vastly long period of time, which enabled the wiring in the vicinity of the heaters causing them to reach high temperatures of (1000F) which had degraded the Teflon insulation. The tank was also impacted from the 8 hours of overheating which was a sign of a potential bomb the next time those tanks were filled with oxygen again. This occurred and exploded on April 13, 1970.”Apolllo 13”
In the rocket, an alcohol-water fuel is combusted with air, which is then directed through 1,244 nozzles, producing the thrust that is necessary for reaching longer distances. (See Figure 1.2) Regenerative heating maintained a fuel temperature range of 4,500-4900 degrees Fahrenheit, while keeping the combustion chamber consistently cool. Once the V-2 took off, it could propel itself into the air for up to 65 seconds, then a programmed motor controlled when the engine shuts down, (50 miles) and at what angle. As it continued on a free-fall path and made contact with the ground, the warhead exploded by an electric contact fuse. (See Figure 1.3) It was used against other Allied cities such as London, Antwerp and Liege; the rockets were ultimately the reason over 21,000 civilians, military personnel, and concentration prisoners were
A bottle rocket is a type of model rocket using water as its reaction mass. They are usually made with an empty two-liter plastic soda bottle. The water is used to pressurize air in the bottle for launching. Which is released rapidly through an opening as it tries to escape. A rocket is subjected to the forces of thrust, lift, drag, and gravity just like airplanes. Thrust is the force that causes
Investigating Factors Affecting the Heat of Combustion of Alcohols PLANNING SECTION Introduction ------------ Alcohols are organic substances, and consist of Hydrogen, Oxygen and Carbon. All alcohols are toxic but the amount that can be tolerated by the human body varies for different alcohols. For example drinking small amounts of Methanol can lead to blindness and even death.
...nched in his front yard, exploded upon liftoff. This was repeated numerous times in the following attempts. Once, an onlooker was almost hit by an uncontrollable rocket. In Homer’s case, although someone could have been hurt, the risks were well worth the possible outcome of winning the National Science Fair.
