lastweek:

Last week I made the air cannon as well as the mount.  The barrel, valve, and pressure chamber are mounted perpendicular to the centimeter grid that will be used to measure velocity.

thisweekplan:

This week will be spent setting up the apparatus in the lab as well as researching methods to obtain an accurate measure of velocity using and SLR.

outsideclass:

Most of the research on velocity measure as well as the design of a projectile can be accomplished outside of the lab periods

Equipment:

We will need to be advised on the best method and setup for this particular experiment.

progress:

I fully expect to reach our first two goals of using high speed photography to make velocity measures and to using physics calculations to confirm the experimental conclusions.

lastweek:

Last week, we completed our set up.  This included setting up the entire apparatus with two flash units, the completed air gun, time delays, and photo gates.  Also, we test fired our apparatus.

thisweekplan:

This week, we plan to fine tune our set up, mainly focusing on the timing with the two photo gates and the employment of the rotating disk clock.  We will be studying the projectile type, shape, material, weight, and optimal design for best firing potential.

outsideclass:

We need to pick up several projectile options at Target and/or Walmart this week.  Also, we need to do some research outside of class about the projectile and possibly create our own projectiles out of clay in the Art Room.

Equipment:

All we need is to have a frequency clocks to add to our set up.

progress:

We definitely expect to reach our goal, even if this means working feverishly outside of class.

lastweek:

Last week, we finalized our set-up, and ran our first set up.  We took pictures of an in-focus, functioning air cannon.  We were able to run several test fires, but came to the conclusion that our current transistor was not providing a small enough segment for us to capture the projectile.  We decided that we needed to change the transistor and re-adjust the delay.  We also took pictures of the rotating disk and decided that, through photographic evidence, the disk was making an obtuse angle.  Finally, we formed several different shapes and weights of projectiles from clay.

thisweekplan:

This week, we plan on getting usable photographs with our new transistor inside the delay box.  With usable pictures, we can begin to analyze the relationship between weight, size, and design of projectiles with velocity.  With this information recorded, we will fine-tune our shape, size and weight in order to obtain maximum velocity.

outsideclass:

We need to study the aerodynamics of projectiles and analyze and record our data from the pictures that we will take.

Equipment:

We will need to use the high speed video camera to definitely prove the angle and rotation number of the disk during the time between flashes.  With the video camera, we will be able to measure and accurately obtain velocity data for our project.

progress:

We expect to reach our goal.  Hopefully, we will have substantial data regarding the relationship between projectile and air pressure to the velocity and speed of projectile.  We are not sure if we will be able to break the sound barrier with current projectile limitations, but we will attempt to do so.

lastweek:

Last week, we captured usable pictures that will be used to analyze the velocity.  We used the high speed video camera to insure that the angle of the rotating disk was indeed an acute angle.  Also, we got an estimate for our velocity with the cone shaped projectile.  I don't have this number - the calculations can be done with the data in my lab notebook.

thisweekplan:

This week, we plan on printing out and getting specific values for our velocity. We plan on adjusting the weight of the cone shaped projectile by shaving off some of the dried clay.  This will allow us to analyze the effect of mass on the speed of the projectile.  After that, we can take pictures while changing the PSI values up and down.  Form this, we will analyze the effect of PSI on velocity.  With this data, we can start to try and optimize the settings to give us the highest velocity values.

outsideclass:

Hopefully nothing.  We might need to create more projectiles out of clay.

Equipment:

We may need to use the high speed video camera.  

progress:

We are going in a good path to try and maximize the velocity.  I'm not sure if we will be able to break the sound barrier, but we should have enough time to start to achieve the highest velocities from our set up.

lastweek:

Last week we obtained more data photos after adjusting variables.  Since we finally got the photogate set up with the necessary capacitor in the delay box for getting the speed right we were able to get consistent pictures with the projectiles in frame.

thisweekplan:

Tuesday we will take the final set of data photos for the  project.  Wednesday will be spent analyzing each photo for its respective velocity.  Thursday and Friday will be spend working on the write up.

outsideclass:

Possibly Analyze photos.

Equipment:

We have out setup finalized.

progress:

We are on track to complete an analysis of velocity using the air cannon and flash setup.
