Wingtip Propeller Theory

 

There have been a number of studies of how efficient putting propellers on the wing tips would be.   We will try to collect some good ones here.

 

Below is a video of a simulation:

Below is a list of papers:

  1.  Analysis and Design of a Small-Scale Wingtip-Mounted Pusher Propeller 
  2. Aerodynamic Analysis and Optimisation of Wingtip-Mounted Pusher Propellers 
  3. Experimental and numerical study onwingtip mounted propellers for lowaspect ratio UAV design



If you want to place solar panels on a wing, it is easier to have a rectangular wing.  I think for this shape wing the wing tip losses as a glider would be more severe and so having wing tip propellers makes for a bigger win than normal shape wings.

Switching from iNav to Ardupilot for Flight Controller

   We had been using iNav software for the flight controller but have decided to switch to Ardupilot the following reasons:    1) Ardupilot can have a "companion processor" like the Jetson Nano that does vision/AI and decides things like which way to go.   We really want to explore what can be done with AI on a solar powered airplane.   Like can it avoid clouds and stay in the sun more, can it scan the horizon with a telephoto camera looking for boats, can it head for a boat automatically, etc.   This seems fun.    2) Ardupilot can use a companion processor to communicate over cell data network (4G) to a ground station.  With this we could fly all around Anguilla and still have communication between the ground station and the airplane.  So from the ground we can change the mission plan during the flight.    We could decide to go to a particular boat, or decide to come home because the change of rain has gone up.   Or if we don't have AI avoiding clouds we could do it

Crowd Funded and Crowd Researched

  After I get one prototype working reasonably well I will update this page with conditions for a prize for improvements in the design. Crowd Research Prizes         The "goodness number" (GN) will be miles flown in one day (relative to air).         Improvements of X percent over the previous GN  will get a prize payout of the amount X * Y dollars.   The Y will start at $200 but can increase as we get crowd funding.             Each time a prize is awarded the GN benchmark will be adjusted.  Technical Requirements   Must use Fomular 250 or foam on Amazon   Must use Maslow CNC if any CNC unless expected prize payout is more than twice the cost of the CNC.  If a new CNC is once accepted it will always be an option for future contestants.   All parts except solar panels and Fomular 250 must be from Amazon   Must be solar/battery/electric - no gas/fuel or fuel cells, etc   Solar panels can be anyplace with public prices but we like solarealdrone.com   Must use iNav on flight con

Development Plan for Production Oriented Solar Airplane

Image
    Introduction  See the previous post for our basic idea of using Maslow CNC to cut foam frames for airplane wings and also to reduce the weight of flexible solar panels.   This type of wing seems light and strong enough and does not take much time to make.   So we can experiment with airplane designs and not be set back too many hours if one crashes or is lost at sea.  The goal is a low cost easy to build solar airplane.  This way we can use them for patrolling.   There is a risk that if cloud cover comes they might not make it back, so we just don't want them to be too costly in terms of time or money.   iNav software We plan to use iNav as the software for the flight controller.   This can work with regular planes, flying wings, differential thrust planes, etc.   It also has conditionals that seem useful to us.   Not sure exactly which flight controller yet and don't think the rest of the design will care too much which is used.
