Free OS UAV Plan!

Posted by Ryan on November 13, 2010 at 6:30am
I designed this baby over the weekend for everyone to have if interested. It should be a very good size for most of your application. I can be built with foam, wood, and composite.


Name: RVOS v.1.0
Wing Span: 1.6m
Length: 1.1m (nose to tip of v-tail)
Max Weight: 6kg
Recommend 4 Channels (Aileron, V-tail, Throttle)
Power: .45 - .65 cu.in. or equilvalent electric power

    I think move the main gear back 10 degree from the 1/4 chord line and add nose gear. Replace the aluminium main gear with a narrower carbon or spring steel wire - it will look more elegant. ;)

    I love this design!

    It is a shame that there is no CAD parametric format that plays nicely
    with version/source control. If FreeCAD adopts an xml/text based
    format it would be the ideal thing to use for open source designs.

    If we could co-ordinate people to do pars of the whole project, it would be a blast.
    Not everyone can do CAD, but that doesn't mean they can't come up with stuff and measure it so it can be put to a file for others. I like the idea.

    Open Source Airframe concept... to do all this work inside a company takes weeks. I´m thinking about deliver a initial airframe concept in DIY and let´s see how it goes.

    I really like this development process, it´s just like Linux... It can work.

    ..now with wheely goodness.

    I was just curious to know what the coefficient factor would be. Understanding that there is a termendous difference when using Foam Core vs Composite Carbon Fiber material. I for one honestly, have never had the necessity or the requirement to calculate the drag coefficient of any wing surface or of anything else before. I knew that the process was quit involved, and that there were a number of factors involved. Out of curiosity, what reference material were you using to define the process in which the equation was manipulated? Non of the text books that I have in my library define the process in the manner in which you explained it. I would like to complement you, for simplifing the process. I didn't realize, that a CAD program had the flexibility to produce the outcome of a wind tunnel, once you plugged in all of the factors. You must have a heck of main frame, with copious amounts a rendering power. If I may, I believe that you stated the you were using SolidWorks with a dash of Photoshop on the side? I was checking out the price of that particular software, and I can see how you can produce such professional looking product. Lastly, I would like to thank the individual who displayed the web site information on the original posting to allow those of us who didn't have SW loaded on our systems to appreciate all of the work that went into the design work.

    @Richard T
    I will place the plane in a wind tunnel in the CAD program and let you know what it tells me.

    Dave Thank you for the technical information update. I was assuming, that you had some sort of home brew wind tunnel that you were using to perform your test's on a working model. That's what I get for assuming :-). Hi .... Hi

    Yes it is, with a little tweaking in Photoshop. The renderer in 2009 is a great improvement over previous versions, with presets to suit most modeling requirements..
