“Don’t paint it!” …(we painted it)

We recently finished up applying primer to the airframe of the DarkAero 1. We had the airplane disassembled for that project but now we are in the process of putting everything back together.
We thought it would be a good time to pause and show you the results of the paint work since the airplane obviously looks pretty different compared to its original naked carbon look. We also wanted to discuss some more of the details and lessons learned from painting and talk through what is next before we fly the airplane.

    The white really looks great too - I'd leave it. At least in places the Caribbean you really end up going light colors everywhere, interior spaces of dark objects (ie, black plastic barrels etc) can become incredibly hot. To the degree you probably have some heat envelope sensitivity light paint is an incredibly easy solution.

    This will handle crosswinds just fine. There is an exponential function of the earths boundary layer, it rapidly becomes nearly zero wind at the surface. The smaller and lower the airplane the less crosswind effects it during rotation and in the flare. It also will land rather fast for most General Aviation type aircraft. Due to wing loading, small wing, short wing chord, low Reynolds Number. Wing loading is your friend in gusting conditions because its less effected by bumps. Speed is your friend in a crosswind because of trigonometry. The faster you go, the lower the crosswind component for any given crosswinds strength and direction.

They will gel coat parts that will be prone to scrapes and scratches, but the rest is bare carbon fiber BUT with a tinted resin so you get that gorgeous texture but with a brilliant red or green color. Some mix of white gelcoat with exposed tinted CF could look amazing on a plane.

  • @DarkAeroInc

    @DarkAeroInc

    Жыл бұрын

    Thanks for checking out the video! Applying paint in the mold is something we could take advantage of, but we opted to not do this on the DarkAero 1 mainly for structural and quality inspection reasons. Paint obscures visual inspection on the mold face of the infused part after we demold it and inspect it for any dry spots. This inspection step is pretty critical for structural parts like the wing skins. There are other inspection methods like ultrasound that allow you to "see through" paint, but they are not as good as having the ability to simply visually inspect everything. The other reason we don't apply paint in the molds is that it would interfere with bonding airframe sections together since we have lap joint jogs molded right into the parts. Of course, there are ways around this too like masking off the bond areas of the mold or sanding the paint off of lap joints, but that probably adds more effort than just painting the whole airframe in a single operation.

    The marine world has been clear coating highly stressed carbon sailboat masts for years - but 5-10 years before you need to repaint. I've never seen any data on resin degredation however i.e. doesn't seem to be a problem. What's the HDT of the epoxy you're using?

    Could you add a clear coat by adding clear UV resistant layers instead of paint and sanding it to a Polish

    Just curious, have you guys ever investigated having an option for a CD-170 engine? I know you guys are worried with other things right now, but I'm curious as to what kind of range it would provide.

    That engine weighs +106lbs more, which would increase the empty weight fraction by over 14% and reduce payload by the same amount or fuel capacity by 17.5 gallons. That would reduce endurance by 1.7hrs and cut range by at least 425 miles at 250mph, 10.4gph. Its also down -30hp on the UL520. So a +14% increase in weight for a -15% reduction in power. Which would result in a substantial reduction in climb rate and possibly cause a dangerous low climb gradient. What would be the point? Spend twice as much on an engine to try and save a few hundred gallons of gas over the next decade or two?

    My biggest wonder, not just with your aircraft but with all composite aircraft, is how the structure survives in weather. Will this aircraft have to be hangared, or will it handle being exposed to sun and rain, heart and cold?

    Have you considered making a carbon fiber toroidal prop?
