    Hybrid Power: IC engine to generator to motor

    Per several requests, here is a new thread for the discussion of power configurations that resemble that of the diesel locomotive or a few of the hybrid cars available today. I know that in previous posts that have touched on this technology the general feeling has always been that there is a...

    Another one of our own passes on

    Just found out another friend passed away recently - Bruce Bashforth, known for the development of the B1-RD ultralight and the MiniMaster, was killed on his motorcycle a couple of weeks ago. Bruce had quite a varied career, including his last position at Dynon Avionics. Had a lot of...

    Articles

    The recent rebuild of our company's web site has eliminated the "Documents" page - I found it interesting that in the two days it's been down, I've gotten several inquiries as to where the articles and reports have gone. I hope to eventually incorporate them into an HBA library but for now I'll...

    Orion site down temporarily

    Since a few of you have contacted me regarding the Orion Technologies site being down, just thought to let you know that it is on purpose and is temporary until I can get the updated site up. For those looking for the articles, I'm thinking of just posting them here instead of the company...

    The passing of a good friend

    Not everybody who contributes to aviation is well known but many often contribute much more than those we know of or read about. One such individual was a good friend of mine, Robert Gornstein, who I just learned unexpectedly passed away a few days ago. I've known Robert for over 35 years...

    Laminate material properties

    I don't recall if we posted this here before but, for anyone looking for a good database on laminate properties, these are the papers generated as part of the NASA's AGATE program. Keep in mind though that in order to get these properties in your laminate you need to use the same materials and...

    Technical references - Books, technical papers, software, etc.

    Due to the frequency of questions regarding reference materials and suggested reading, I am creating this thread to reference particular sources of information that the designers within our compendium of members can use for the development of their ideas and/or for the refinement of their...

    Carbon composite tube and plate products

    This seems to be a pretty comprehensive site for tub and sheet products - one of he better ones I've seen and the prices don't seem to far gone: Rock West Composites / Carbon Fiber tubing & Filament Wound Tubing

    Toray carbon fiber properties

    For general information, here's a bit of data I ran across today. I wouldn't necessarily use this for design but it is an excellent indictor and can be used for comparison. Keep in mind all the data is for unidirectional material (no weave): “ŒƒŒŠ”Ž®‰ïŽÐ^ƒgƒŒƒJƒgƒbƒvƒy[ƒW (Don't mind the...

    windshield material

    Just a general question here - assuming price is not so much an issue, what is the better windshield material, Acrylic (Plexiglass) or Polycarbonate? I know the latter is more expensive but is far stronger, more scratch resistant and more impact resistant than the Acrylic, but that's about...

    Engine Additive

    Once or twice before I mentioned herein that I use an additive in my engines in order to supplement the oil's protection against wear and corrosion. The product is called Microlon and is FAA certified for aircraft use. This morning I added it to my current airplane, which has had a major...

    Laws of Physics

    Generally I don't pass this sort of stuff on however, having run into similar attitudes or opinions in the airplane industry, even though this excerpt is not airplane related I thought it was priceless and worth sharing..... Laws of Physics: From a senior level Chrysler manager: Monday...

    Allowable CG range based on static stability

    Don't you just hate it when you've been doing something for years and then discover a glitch in your process? There being no other sources of software for aircraft design (as opposed to analysis), years ago I undertook writing my own. Over the years it has culminated into a rather large...

    Wittman type tubular steel gear

    Recently we touched upon tubular steel landing gear as associated with the Wittman airplanes and as now used by RV and others. Someone here posted a link to an Oregon fabricator of that gear but I can't seem to find it. Anyone? Thanks.

    Acro Sport II

    An older gentleman stopped by my hangar yesterday to look at what I was up to. In our discussion he mentioned he's selling his bipe. Always being curious I asked him if I could take a look and got a surprise - this is a nice piece of work. It's a plans built Acro Sport II with about 80...
