What is the most efficient design for an aircraft limited to a maximum velocity of 30mph at a maximum altitude of 100ft?
The objective is to minimize drag and weight. The payload would be 1 human, and my budget is approximately 100,000 dollars (more can be done) for materials I was thinking airloys (because they are light and strong). The end goal is to go more than 74 miles on flat train using human power.

My guesses are aircrafts shaped like a sail plane or a Ground Effect Vehicles (GEVs).

  • $\begingroup$ @mins For a human-powered aircraft, wouldn't the range be mostly a function of how long it takes the pilot to get tired/hungry? $\endgroup$ – reirab Feb 3 '16 at 17:45

    $\begingroup$ This question still seems very broad. What kind of 'efficiency' are you talking about? Just the least power input on the part of the human to sustain flight? If it's that, wouldn't the answer basically just be "Use a glider and forget the human-powered part?" $\endgroup$ – reirab Feb 3 '16 at 17:48

    $\begingroup$ It looks like you're asking something that normally takes a team of engineers to answer, and judging by the variety of aircraft out there, ten engineers will give you eleven different answers. $\endgroup$ – Sanchises Feb 5 '16 at 0:09
