    "M-Wing"?

    I stumbled on this picture in a what if modeler forum where the wing was called a cranked wing. On wiki it was called a M-Wing with the statement that the idea has been studied many time but never used on a plane. I can't find any sign on these studies and besides messing with the balance can't...

    Aspect ratio and weight

    In researching ideas for a fast efficient cross country plane I've started looking at motor gliders. From what i under high aspect ratio wings are good for low drag at low speeds and low aspect ratios are better for high speeds as well as being stiffer and thus being able to be built lighter...

    Hot Duct

    I've been reading on ducted fans and have read about cooling ducts for liquid cooling solutions. It seems that a duct design that slows airflow through the duct is beneficial to both cooling and propulsion ducts. In the fan a duct design that decreases airspeed through the duct will increase...

    Experimental Aviation. Maintaining the status quo or on the bleeding edge?

    General aviation is running on extremely old tech and in many cases expensive to boot. FAA certification insures that new factory aircraft either maintain this convention or become prohibitively expensive while old aircraft are forced to remain obsolete to maintain their type certificate...

    Compression ratio Mogas Vs. Avgas

    I've seen a lot of people listing the ability to burn mogas as an advantage of an auto conversion. Taking advantage of this requires both limiting the compression ratio of your engine and trucking mogas to your airport if it's not already available there. Higher compression ratios can give you...

    Lost in translation

    I'm interested on converting a design I like from aluminum into composite. Besides the obvious structural redesign necessary are there any changes needed just because of things that work well in metal but not in fiber? The design I'm looking at emulating is the Prowler. It will be a while before...

    Magnetic gears

    I've been reading about magnetic gears and see a of potential in a PSRU or even a psudo direct drive. However I'm having a hard time locating a mathematical model to predict torque capacity and slippage. Anyone know were I can look for this information?

    Contra-rotating PSRU

    If a PSRU is determined to be the most effective way to get power to the prop why not use a planetary gear based one and countra-rotate a prop. 5-15% efficiency gain over standard props is significant and the drawbacks of weight and complexity are already present in the PSRU. The net is more...

    Hello

    Hello I've been lurking for a while but decided to join today. I haven't started building yet I'm still researching what I want first. My background is in avionics and electronics for military aircraft and I intend to design new electrics for experimental aircraft.

    Electronic aircraft health monitoring

    I've spent most of the last 5 years installing a system into military aircraft that using accelorometers strategically placed around the airframe could determine the general condition of the various engines gearboxes and drive shafts and associated bearings in some cases they increased the TBO...
