I built it and my son destroyed it.

Project Summary

After Getting the project cut out of the foam and starting to put together using a paper airplane template to do a foam F-14 Tomcat.  Where it folded over another piece that was previously folded to that point I cut all folds out and pieced the plane together to get a model that resembled what it should look like.  After that I ran into the issue of weight distribution front and rear to get it to fly properly.  After one evening of work and still not having it fully weighted out, my now 16 month old got a hold of the plane and tore it apart.  I was happy to have a least a couple of pictures of what I had got done to that point.

I picked this because it looked cool and I thought it would be easy to complete but I ran into snags that required me to modify the original design in order to make it go together.

Foam Cutter Project – Team Build a Glider

Project Photo

Project Summary

We build a small glider. Our goal is to make it fly around ten feet.

Team Members

Josh Chase, Jordan Steinbrock

Project Analysis

We picked the design we did because it was easy to make and looked like a plane.

Other than the foam, the only material we used was four paper clips.

The foam cutter was very useful for this project. It allowed us to easily cut out the plane design we had on Inkscape.

To test our plane we threw it. If it didn’t fly how we wanted it to we added a paper clip to the nose. Finally, we figured out that four paper clips worked well.

The plane flew about how we wanted it to. If we had more time we might have been able to create a bigger plane that flew better.

Project Summary

Our assignment was to create a glider using the InkScape program and foam cutter. 

Team Members

Chase Minor and Israel Taylor

Project Analysis

We got our design from the specs of an F-22 fighter jet.  We weren’t sure if it would actually work for a glider but we were certain it would look cool.  We cut it out and put it together and it did look cool and flew for about five feet before it spiraled out of control.

Materials:  1/4″ foam, paper clips, tape, hot glue

BUILD: The foam cutter and inkscape really worked well for what we were trying to do.  Inkscape allowed us to look at the specs from the actual plane and replicate it as close as we could onto the cut board.

TEST & TWEAK: We didn’t edit the inkscape at all after the initial build.  We added more weight to the nose and ended up taping another tail fin between the two original ones for stability.

FINAL THOUGHTS:    We are very happy with our design.  We think it looks good and performs adequately.

Project Summary

It was our goal to create a glider that can fly a minimum distance of 10 feet, and was structurally sound. We went with the basic glider design, long wings and long lightweight body to try and achieve this goal.  The glider body is all cut-out with paper clips and a resister on the nose for additional weight.

Project Analysis

 The design was a basic glider design, long wings with a very light body, we hoped this would help the glider maintain longer distances of flight. The design was made for mainly performance and easy of construction. Unfortunately the wings were too long and made the glider flip over uncontrollably. It was then decided that the length of the body of the glider should be increased so as to prevent such occurrences, with the addiction of a few paper clips and a resister to the tip of the plane, there was sufficient weight to keep it from flipping over. Structural Integrity, however, was compromised in the goal to a perfect glider, and the glider did break (it was fixed).

Materials:

1/4″ Foam for body

2 Paper Clips 

1 Resister

Scotch Tape

All-Adhesive glue

Build: The foam cutter turned out to be a crucial part of the design, the cutter seems to be most appropriate for designs in which pieces are cut out and then put together by hand. The process was relatively simple, the only difficult part was orienting the head of the cutter to the desired location. It is the team’s feeling that they are well enough taught in the ways of the cutter to use it again. 

Test and Fix: Describe what you did to test and improve the flight characteristics.  Did you edit the design again in Inkscape and cut it out again on the foam cutter?  If so what changes did you make to the design and did it have the effect you expected?  Did you have to add weight to the nose to get it to fly well enough? We had to re-cut the body panels of the glider to get it to fly somewhat correctly (to stop it from flipping over). We used Inkscape to increase the length of the body panels and then cut them, It managed to stabilize the flight, and with the addition of paper clips to the nose, we got the glider to stop flipping.

Final Thoughts: Whereas the original flight was less than successful, the design was updated and a (semi)-stable flight was achieved. The team feels they were able to quickly create an effective design, and would not do anything differently. If we had more time, a very advanced and aerodynamic body would probably have been built. 

 

Foam Cutter Project – Team The Bat Plane

Project Photo

Project Summary

Since this is October, the Halloween month, we decided for our project of foam cutting to be a plane designed as a bat. We used Inkscape to design the bat plane and build it in the workshop of engineering department. 

Team Members

Mohammed- The general design idea, cut the plane out of the foam, built plane, test the plane

Blake- Design the bat plane using Inkscape, cut the plane out of the foam, built plane, test the plane.

Project Analysis

We thought that a plane designed as a bat would be nice since Halloween is very close. We had the simple design for the bat plane but adding more curves to it would give it the smooth flying and nice looking.

We used materials as foam for the structure of the plane, cutter knife for shaping the edges, and a paper clip to balance the bat plane flight.

Using Inkscape was not easy sometimes because of the first time using it. It is very helpful for the design and we got help on it in the workshop. At the workshop we used the foam cutting machine to cut out our plane out of the foam. We loaded the bat plane design to the cutting machine and let the machine do its work. After that, we used the cutter knife to take off our plane parts and shape the edges. We got two samples of the bat plane so we can test the design multiple times in different ways. We balanced the paper clip couple times and the bat plane flew very well.

Foam Cutter Project – R&R

Project Summary

We had decided as a team in class that we wanted to do a basic model glider. We had figured that simplicity would work the best and fly fairly well also. One of the issues we had was when the plane was first cut out was that the wings were to large and wouldn’t fit in the cut outs properly. After modifying the design on Inkscape and re-cutting the design. Everything fit perfectly but the plane didn’t fly the best so after adding a few paper clips to the nose. It was a great test flight after that. 

Team Members

Rachel Linot- Created the original design and cut out the first test plane.

Rachel Schneider-Helped modify the first test plane and re-cut the final test plane. 

Project Analysis

We picked the design we did because of the simplicity it. Our main priority was to make certain that the plane could fly. We achieved that by constructing a plane that was relatively light weight and aerodynamic. It was a good design choice because the plane flies and our objective was accomplished. We used three additional paper clips and foam for our materials. The foam cutter was extremely useful for this project because of the precision that the machine cut the foam with. It was nice to just put in specific instructions and have the machine cut out a plane for us and to not have to worry about making any mistakes as if we were to cut the plane by hand. I think we learned enough to use the foam cutter in the future. We tested the plane twice and when it did not fly far enough the first time we added paperclips to the nose of the plane. Yes, we modified the specifications in Inkscape and then re-cut the plane. The plane’s wings were made smaller and the slits for the wings were made slightly bigger. We had to add weight to the nose to get it to fly properly. Yes, we got it to fly as well as we wanted it to when we started this project. I would not do anything differently, other then just make the wings smaller the first time rather then the second. I would like to make a jack-o-lantern out of foam.

Foam Cutter Project – Team A+

Project Summary

In this project we were given the task to use Inkscape and the foam cutter to design and build a plane that flies at lest 10 feet.

Team Members

Robert Osborne- Basic Design, Managed Inkscape, built plane

Matthew Barnes- Revised design, built plane, fine-tuned plane

Project Analysis

For the design we wanted to go with simple and effective. Over complicating the design can sometimes make it perform worse. We weren’t particularly concerned with how it looked. We were more concerned with making it fly well. We feel our design was a good solution because it was able to fly more than the requested distance.

For materials we used we used foam for the substance, paper clips to add weight, and an x-acto knife to fine tune the plane.

The foam cutter was definitely useful as it made it much easier to cut out the shapes we needed. It allowed us to be precise in our measurements and symmetry. Its good for making basic shapes that we can use in projects. The foam cutter process was simple enough and most of the time was spent designing and tweaking. There is still a lot to learn about Inkscape but for most projects it should be simple enough to use again.

We did a lot of tweaking of the design.  The redesigning was done without the help of the foam cutter, using a knife to reshape the plane instead. We reshaped the wings, lightened the base, and added in slits to better position the wings and the horizontal stabilizer. We also added several paper clips to add weight to the nose so it wouldn’t flip over.

The plane flew just as well as we expected it. We didn’t test out its full range due to the length of the room. If we were to start again from scratch we would most likely go for a different design, one aesthetically pleasing that can still fly well or better.

 This was the basic design when we cut it out. We did a lot of tweaking outside Inkscape without the foam cutter. The horizontal stabilizer was added afterwords from scraps.

Project Summary

Our goal was to make a glider out of 1/4 inch foam that would glide at least ten feet. We brainstormed up two designs and then narrowed it down. We made the design in Inkscape and used the foam cutters to cut the foam. From there it was trial and error on adjusting the wings to get the maximum distance with little to no stalling. 

Team Members

Alex Harrison, Austin Griffith & Tom Wineland :)

Project Analysis

To pick our design Austin and Tom each came up with a design. Austin went with more of a cool design. He chose something similar to a f-22. The group thought that although this plane design was awesome it would need an engine to fly for distance but would not be great for gliding. On top of that it would require possible gluing to construct and would be more complicated. Tom’s design was the most applicable. It provided one large wing with one small wing at the tail. It also was easy to assemble  where we only had to slide the wings in the holes of the base of the plane. In the end we went with Tom’s Design because it was obviously the best.

MATERIAL:  foam, tape(Only to fix some overzealous cutting on the wing holes)

BUILD: I believe the foam cutter was useful to add to the overall neatness of the project. It kept everything straight and precise. Things that could not have been done by hand. I think it is most appropriate for projects with lots of small and precise parts or things that need to be massed produced. I do not think much needs to be improved on the cutter i believe more experience will solve most of the problems. i think that more experience is needed to do a more intricate project on the foam cutter.

TEST & TWEAK: The first problem we encountered was that the plane would stall. To counter this we moved the front wings towards the back of the plane. This eliminated our main problem. From there we realized that the base of our plane had excess height. We debated editing it in Inkscape, but we decided to cut it by hand with a ruler. The last problem was that there was not enough weight in the nose so we added paper clips with trial and error to find the perfect balance of the wings placement and the weight. Then we taped the wings in place to ensure accuracy. ( we used minimal tape as not to affect the plane)

FINAL THOUGHTS:   The plane actually flew further than we expected. It goes easily 10 feet. If we were to start from scratch i would make the plane shaft smaller in height and make the holes smaller so the wings fit more snug. Austin  and Alex would like to build a box with different shelves and compartments. Tom would like to make gears.  

Advice: start early because it takes awhile to get use to the software. It is not as simple as it looks.
