Thank you for your reassurance....my experience is generally restricted with structural and mechanical engineering skills and the advanced calculus was never mastered by me as far as aerodynamics are concerned.
Eventually we can run a test on the foil shape and the props surface areas/angle of attack to find the optimal rotation speed required to hover for 45 seconds, then lift to the height required........we honestly see the potential, but with so many attempts, the school based design teams were left with advancing the previous vehicles and trying to make their "hovercraft" sustain flight.......we have had success reinventing the Pedicab, the modern rickshaw, and are now moving onto the entry for the vehicle design summit this summer at MIT. With this engineering as a background we are able to achieve a greater advantage over other riders and gain the momentum to get going on this project.
We are hoping that the rotor speed will be accelerated from the internal hub gear we are including in the drive train, allowing us to get it up to speed on a gradient scale through gears 1-4, by fifth we hope to be at a 1-1 ratio with the internal hub, and will have generated 8.94 full rotations for every rotation of the main pedal powered wheel, if one rotation per second (definitely possible) is maintained, then we will have created a rotor with 40 sq ft of surface area traveling at 535 RPM's, far more than is needed to attain lift of a regular sized helicopter that usually runs at 400-460 RPM's and weighs a ton.
Although the rotors on a regular heli are also able to produce lift from adjusting the angle, we have a fixed angle of 2% that we feel will be enough to allow for the slipstream effect to be more fluid with less drag and still create lift, and direct the trailing edges' airflow directly into the main lift producing area of the next blade, after the vacuum has collapsed upon itself and returned to it's original density........by generating more momentum, and creating the final rotor rpm to sustain, with at least three gears left to get off to a higher altitude, there is no way we can lose.
Would you be interested in handling the advanced calculations as a co-conspirator/awardee??? We are merely looking for scientific calculations to back up our design, so we can obtain sponsorship with endorsements, to make the process go smoother.
