semi vtol edf design ( based off the concept art of the halo wasp)

Posted by daren jansen on October 18, 2017 at 1:00pm

so in the title i mentioned the design im building is a semi vtol edf design from the concept art of the halo 5 wasp 

so my plan since they dont make edf motors big enough or powerfull enough i will use multiple electric motors in a configuration  to make a edf motor diameter of the blades would be 1 foot. so in total 8 motors for the main lift/ hovering edf motors 4 each for the 2 main edfs in the wing. questions being i need 50-100 static pounds of thrust,powerfull enough to lift a 50 pound design or more , prob pushing the weight limit and this weight would include everything onboard

    first before this big design i plan on building a smaller plastic and foam version

    does anyone get what im trying to do with this? do you think it would work?

    Hey, At first I thought you were crazy, but what you propose could be possible. There are edf systems big enough, with eight of them, to lift a 50 lb. craft.                                        

    look here

    So here's the bad news. This thing is going to cost minimum $12000 to $15000 USD. I used an unrealistically optimistic battery weight as 2/3 of the craft's total. That battery will cost around $1200. You will be lucky to get ~4 to 5 min. flights. Projects always start out with total optimism and that is what I did with this quick analysis. So you may only get 2 to 3 min time.

    edf's are optimized for speed, like in jets. Using them in static thrust, as in hovering, is the most extreme inefficiency, thus the short flight times. The good news is that the motors will probably not meltdown due to the ridiculously short flight time.

    Are you doing this for a movie or do you just have too much money?

    i should definitely explain my plan a bit more im well aware that edf motors are high rpm thou are you aware that edf motors can be made very simply by putting a shroud on a propeller to gain more efficiency my plan is to put 4 high grade electric motors on a gear system in a configuration like a jet engines to perhaps have alternating propellers, i will be basically making a custom edf set up, do you now get what im trying to do?

    im wondering what kind of motors i can get that would work for that and the best kind of blades ive done some research but there is a lot any thoughts?

  • daren jansen October 18, 2017 at 1:01pm

    I would like to hear any and all thoughts
