Taking requests for an airframe design !


Over christmas I'm going to make an airframe just as an exercise, and since I don't actually need a new airplane I'm taking requests for payloads and missions. I'd rather make a plane thats useful to someone than one thats useless to everyone, catch my drift?

so if you have any suggestions or are looking for a plane yourself, go ahead and leave your mission and payload in the comments below !I'll test using dummy payloads of equal weght (max payload around 200g, an autopilot counts as part of the payload !)

i'm an aeronautical student at the moment, and you may think is wierd but I actually enjoy the frustrating process of making a quality, mission specific plane!

  • Thinfilm is relatively low efficiency and less in flexible lite substrates .The cells you need are sunpower´s .22-23 % and quite thin ,then you need to find a way to curve them .....I found it!!!!


    My efforts are in a direction of making the drone less harmfull , ducted props came to my mind .

  • Ask chris anderson, it's probably his plane!

  • Id like to get everything in this picture, How much for 1 

    or if its too much just the autopilot all electrics and set up for a camera and forget the base station

    or whatever


  • thanks squalish, thats the kind of challenge i'm looking for !  I'll look into it more in depth soon , but i got an exam at 1o'clock today :]


    Keep requests like these coming please!

  • 399' ha ha ha

  • Re-reading your RFP, and the 200g maximum payload, I guess I'll scale back a bit:

    Mission: I'd like to see a twin boom solar airplane that can fly from 9 to 5 over flat forest without landing, using thermals, or exceeding 399'. Use the payload at your leisure.

  • You want a challenge? Here's something that I believe is possible, that would be useful for a lot of people. I hope I've included challenging but reasonable constraints. The fact that people have designed 48h endurance solar planes and manned solar gliders leads me to believe that it's plausible to do this in way that hobbyists could build with a few thousand dollars.

    Low-altitude (399') aerial photography, with ability to take both straight-down and oblique photographs at various angles - uses two pancake-lensed Panasonic GH-2's for wide field of view & stereo capability. Needs to autonomously circle/follow the user while they travel at up to 40mph in 30mph winds (maximum transient airspeed 70mph, usually much less) for 8 hours at a stretch without refueling. Needs to disassemble down to parts that fit through a 7'x2.5' doorway, and be re-assembled in the field for a stake-based high-launch that can clear a 150' obstacle with only 300' of takeoff runway. Landing needs to be non-destructive on the aforementioned 300' x 150' high runway of flat grass.

    My speculative thinking on the subject:
    Take a pair of Super AVA-E planes to make a twin boom sailplane with a single joined tail, then get some high efficiency large diameter folding props optimized for cruise speed, and mount them well ahead of the fuselage, directly on each boom. A twin boom design takes advantage of the wing's strength by spreading out weight like in the Helios aircraft, while at the same time having the joined tail as a strongly leveraged reinforcement. The booms are basically a pair of carbon fiber fishing rods in the Super AVA-E. Unlike manned aircraft you don't need a strong passenger pod, so the booms can be much farther apart. Strong dihedral on the portion of the wing outside of the booms allows for stability.

    The shape and control surfaces of the very wide tail remains an open question, but note that stability and efficiency are the goals.

    Power it with a large array of thin-film, high-efficiency solar panels. Whether to adjust the chord of the wing in order to allow for larger panels (& on the whole wing or just the portion between booms?) remains a question.

    Each camera needs the ability to adjust for roll angle via RC, but doesn't need the complexity of pitch and yaw angles as well. They should be mounted one to a boom, but the optimal method of mounting remains a question.

    Aerial photography doesn't function at night, so your plane certainly doesn't need to bother trying to store much more energy than is necessary for launch - it just needs to fly from a few hours after sunset to a few hours before sunset.

  • So Nobody wants a free, original, unique plane optimised for their payload and mission ?

  • That's a very good point!
