The potential of a Franz Schöfmann Helicopter

[HoodGigga]

Hello,

I am interested in building something similar to the Franz Schöfmann electric helicopter and would love to hear your thoughts about it.

• Could it be improved to be safe enough for normal flight?
• What would the flight characteristics be like?
• Could it win the GoFly prize?
• I would like to develop it further, are you interested in forming a GoFly team?

Some ideas I am wondering about:

• single rotor design, with electric motor acting upon the air frame to counter torque, or innovative electric propulsion method so that anti-torque isn't required similar to how a jet-tip works

I wonder whether the paper below might be helpful

Good luck with your project!

Thanks, I'll check that out.

A minimally powered, low speed, high efficiency rotor would be an interesting design choice:

Crowdfunding hope for human-powered helicopter project

Last September, the Gamera II team from the A. James Clark School of Engineering got so close to claiming the Sikorsky Prize of US$250,000 for human-powered helicopter flight that the American Helicopter Society must surely have been preparing to pull the dust covers off the safe and hand over the…

Thanks for those pictures, Franz is off again Amazing guy, have you seen this thread ? https://www.rotaryforum.com/threads/project-ladybug.1146758/

Interesting - keep us updated
Do you have any links to Franz Schöfmann electric helicopter?

@btd1982 thanks for the link, it was suggested to me when creating this thread, very interesting read. Your latest video is awesome! The humour still has me giggling. If you feel inspired to create this smaller rotor, please go ahead .

@Jens Sorry, I should have credited the link in the original post, i found the originals here. If you come across more, I would be happy to see it.

Thank you
It's probably the simplest flying coaxial invented and very tempting to go and build one. I was informed that Franz has stopped his experiments disassembled his flying machines and now is against others doing such things. Not due to any incidents but a change of outlook. Shame in my opinion but still a great legacy. He was one of the people who inspired me and still does. I expect I'm quite a bit heavier than Franz which would make it harder for me to succeed in flying one but I'm sure achievable with longer blades.
