Hey everyone, welcome back to another one of my great blogs about Project Ventura. So you guys all know by now that we’re working on the final milestone, Milestone 3.
We’ve all been pretty busy lately working on the various mini project that still need to be
done in order to get this Airstream looking nice and spiffy. Last class period I was in the Airstream for basically the entire class period. I worked with Julie to create the template for the rounded curve of the couch on the end of the Airstream. It was kind of a struggle to do this since we kind of had to wing it a little bit. We’d cut out what we thought it would look like, then we’d put it up against the curve and we’d cut more accordingly. It all worked out good in the end and we cut out the curve on a piece of wood using a jigsaw.
Now we’re kind of at a random point where we can’t do much working on the Airstream so we’re moving on to work on our e-book chapters. My group is doing the two chapters of ‘Making Models: Scaled Model of Floor Plan’ and ‘Fluid Power Systems and Control Systems’. Since there are three of us in our group we split the work in three. Faith is mainly going to be working on fluid power systems, Julie is working on control systems, and I’m going to be working on making models. I don’t really know much about fluid power systems or control systems so I decided to do some research on them for today.
From my research I learned that a control system is a set of components that perform a task together under the direction of either a computer or a processor. In control systems for manufacturing equipment the program will tell the computer when and how to control the output devices. Control systems are grouped into being either open looped systems or closed loop systems. Open loop systems will work under the assumption that no errors will occur. Because of this, there’s no feedback in this system that would allow it to readjust so the input will either succeed or fail. An open loop system is similar to a closed loop system except it has one or more feedback devices so that the program can monitor and adjust the output. This feedback is generated using sensors.
I discovered that fluid power is the use of a liquid or gas under pressure to generate, control, and transmit power from one location to another. The power generated can be divided into either a hydraulic or pneumatic system. Hydraulic power is drawn from pressurized oils or other liquids while pneumatic power is drawn from compressed air.
Well that’s all for today, I’ll talk to you guys on my next blog! Keep checking in to see updates on our e-book and our final work days on the Airstream! We only have a few more weeks until we wrap up with Project Ventura!
