    The Business side of Homebuilt Aircraft

    Hi all, wondering who on here is on the business side of the homebuilt aircraft industry? I'm tempted to start a business based primarily around the most simple of my designs: the modular SDDR/pt103/microlight/possibly motor glider design. The design has not gone through detailed design and...

    The 'daydreamers' your craziest designs and concepts here

    Hi all, time for a thread to post ideas, concepts and designs you wouldnt normally share for fear of ridicule. Doesnt have to be practical or possible, but hey, maybe someone has a good idea worth taking further. Maybe some of the non-engineers (usually the most creative) have an idea and...

    Max altitude without pressurization but with supplemental oxygen?

    Hi, just a curiosity more than anything. How high can one fly without cabin pressurization but with an oxygen mask on? There must be a point at which ear drums explode and blood boils.

    Chopped strand mat as a direct replacement for plywood?

    Hi all, i'd like a little input/second opinion on the following, i'm just pondering ideas here. As some of you know i'm building a minimax himax, and currently having problems sourcing the correct grade and thickness of ply. It's surprisingly difficult, and due to sizes of sheets the delivery...

    TEAM minimax 1700R Himax build log

    First off, this is going to be a slow project, so dont be expecting daily updates, but it will reach completion, my target is 2 years. Today is day 1: I'm planning to build this little plane in a modulat fashion so as to reduce long term space requirements throughout the build. At the...

    On being decisive - stop dreaming, start building.

    Hi guys. I've been on this forum for a couple of years now and so far not even started building. I've learnt loads, and since i joined i quit my job and embarked on a BEng Hons in Aero engineering, so i have the people of this forum to thank in part for that. Now i want to fly, this is my...

    tail rotor (or two) to replace empenage of fixed wing ac, why not?

    as title suggests, could two electrically driven tail rotors replace the empenage function on a fixed wing aircraft? and what would be the limitations and disadvantages? reason for asking is that i'm in the middle of calculating tail volume and it's huge, and i bet i could get the same force...

    Wing weight estimation - some help with data please?

    Hi all, i'm trying to estimate wing weight of a sparless (foam core) wing. I'm struggling to find the data required to calculate this, what i'm missing is the area of a clark-y airfoil per unit cord (ie. Area is proportional to cord)...cant even find the line equations :/ wonder if anyone could...

    What to build? 2 seat, 39kts stall speed, under 450kg total weight.

    Hi guys. While dabbling with designs and projects for uni I'm a long way off starting to build any of them, this will come with time and experience, but in the meantime I want to get building! I've found a workshop locally that would be ideal, and think I'll sign the lease within the next few...

    Safe 'worst case scenario' landing speed - your thoughts

    Hi guys, working on a concept at the moment which utilizes a degree of powered lift. In sizing, i can theoretically make the main wing very small, however it got me thinking about worst case scenarios. Lets say flaps jammed closed and no power...what speed would you consider safe for...

    Aircraft modified to fulfill a purpose not originally designed for?

    Hi guys, been away a while...exams!! almost done. Anyway, i have a report to write about the aerodynamic factors affected by the modification of an aircraft to fulfill a purpose it wasn't originally designed for. Looking for suggestions and inspiration. Ideally something with plenty of widely...

    Fixed gear amphibian?

    Hi all, very busy with Uni lately and so haven't been around much. Just pondering some thoughts and was considering a fixed landing gear on amphibian hull. Does anyone know of any aircraft that used this? I've tried a few searches but can't find anything. For a single seater so a retracting...

    engine choices - please help! (4 stroke, EFI, 30-50hp)

    Hi guys, struggling to move forward with my design, as i have no idea what engine to use. I don't want to design around a generic kinda size, i want to find the exact engine, exact dimensions and therefor be able to size everything correctly, not just leave a space that will fit loads of...
