Cannon Project

  1. 1. PVC Cannon Project<br />by Brandon Skidgel, Louis Hickman, Hyatt  Hopkins, and Brad Ivy<br />
  2. 2. How Cannons Work<br /><ul><li>Old Cast Iron Cannons
  3. 3. - Used gunpowder to 'explode
  4. 4. - Then Generates a force of pressure
  5. 5. - which pushes out the cannon ball</li></ul>                                                             <br /><ul><li>Potato Cannon </li></ul>            - Barrel is connected <br />              to the tank<br />            - A combustion substance it put <br />              into the tank <br />            - It is then ignited<br />            - Making an explosion<br />            - Which pushes the potato out                                                          <br /><ul><li> 
  6. 6.  </li></ul> <br />
  7. 7. PVC Pipe<br />HISTORY<br /><ul><li>Discovered in 1835
  8. 8. 1912 first industrial development of PVC starts
  9. 9. 1920's try to make PVC copolymers
  10. 10. 1932 PVC copolymers are put out on shelfs
  11. 11. 1936 to 1939 over 400 residences were installed with PVC
  12. 12. 1950 through 1960 PVC pipe had a dramatic advance
  13. 13. 1950's American and European companies use PVC pipe</li></ul>CHEMICAL STRUCTURE<br /><ul><li>(CH2-CHCl)n </li></li></ul><li>Propellant for Potato Cannon<br /> Hair Spray-Hair spray was invented during WWII to hand out to the soldiers.<br />We are going to use hair spray as the propellant.<br /><ul><li>Reason- The reason behind this is that both the propellant gas [propane] and the solvent for the binder [alcohol or ether] are highly flammable. And when the  aerosols combine it is very EXPLOSIVE!.
  14. 14. Backside to using Hair Spray as the propellant-The backside to using Hairspray as the propellant it that after shooting the potato gun alot the nonburnable sticky gunk in the hair spay will stick to the sides of the wall and make the igniter spark stop working.</li></ul>More Propellants- there are also other types of propellants to like:<br /><ul><li>WD-40(Which costs more)
  15. 15. Carburetor Cleaner
  16. 16. Spray Paint
  17. 17. Propane
  18. 18. Ethanol
  19. 19. Hydrogen(All of which was just listed is more expensive than Hairspray but more explosive)</li></ul>Ignition-So when you ignite it after spraying it in the back end of the potato cannon it will explode inside of the firing chamber and force the potato out at extraordinary speeds.  <br /> <br /> <br />
  20. 20. Solvent Welding<br />Solvent Welding- Solvent welding is the process of joining articles made of thermoplastic resins by applying a solvent capable of softening the <br />surfaces to be joined, and pressing the softened surfaces together.<br />Adhesion is attained<br />by means of evaporation<br />of the solvent, absorption<br />of the solvent into <br />adjacent material and<br />/or polymerization <br />of the solvent cement.<br /> <br />
  21. 21. BLACK POWDER<br />What is Black Powder-  basic black powder is made of 75% potassium nitrate, 15% charcoal, and 10% sulfur. These ingredients are ground to create a uniformly textured powder.<br />How did Black Powder come out-By the 9th century Taoist monks or alchemists searching for an elixir of immortality accidentally stumbled upon gunpowder.<br />What Black Powder is used for-  Black Powder is used in all kinds of things in the 19th and 20th century, such as- Cannons, Guns (muskets), and any sort of bomb. (And there were millions of guns and cannons).<br />A simple, commonly cited, chemical equation for the combustion of black powder is<br />2 KNO3 + S + 3 C -> K2S + N2 + 3 CO2.<br />A more accurate, but simplified, version is<br />10 KNO3 + 3 S + 8 C -> 2 K2CO3 + 3 K2SO4 + 6 CO2 + 5 N2.<br />
  22. 22. Cannon RiflingRifling is little grooves on a cannon tube or a gun barrel, that allow the projectile to spin as it fires out, making the projectile go faster.<br /> <br /><ul><li>Rifling was introduced in 1520    ~Invented by August Kotter</li></ul> <br /><ul><li>Not common until nineteenth century
  23. 23. Modern rifles are broached
  24. 24. ~Broach-a toothed tool toremove material
  25. 25. ~Introduced in early 1850s                       
  26. 26. ~Originally made to cut keys</li></ul> <br /><ul><li>5 types of broaches</li></ul>    ~Slab..........................Flat surfaces    ~Slot...........................Various dimensions    at high rates    ~Contour....................concave, convex, and irregularshaped surfaces<br /> <br />     ~Pot...........................cuts the        outside diameter of cylindrical piece    ~Straddle..................cut parallel surfaces on opposite sides     <br />
  27. 27. Types of CannonsThere were many types of cannons during the civil war...<br /><ul><li>Rifled cannons  </li></ul>           ---Rifling, or grooves, in the tube         which make the projectiles spin as theycame out, allowing them to be more accurate.         ---7.5 inch Widow Blakely <br /><ul><li>Smooth Bore</li></ul>--- Smooth tubes that usually fire cannon balls ranging from 12 pounds to             32 pounds.<br />---10-inch Columbia<br /><ul><li>Mortars</li></ul>            ---introduced in 1861 shot at a 46 degree or higher to come down on top of the enemy<br />            ---13-inch Dictator<br />
  28. 28. Projectiles<br />Shot-Solid projectile that reliedon kinetic energy to destroy targets    --Smoothbore cannon shot= a heavy, solid cannonball    --Rifled cannon shot= a solid iron or lead conical shotShell-Explosive projectile that blew up into fragments upon ignition    --Smoothbore cannon shell= sphericalshell with timed fuse    --Rifled cannon shell= conical shell that used percussion fusesCase-Anti-personnel projectile that sprayeddown iron balls when detonated    --Smoothbore cannon case= spherical case that fragmented    --Rifled cannon case= conical shell that showered iron or leadballsCanister-Deadliest type of projectile, shot heavy lead balls in shotgun blast    --Smoothbore cannon canister= cylindrical canister that destroyed infantry<br />    --Rifled cannon canister= double canister was the most deadly<br />
