Solidworks is really nice as it allows you to set the density of materials and shows you the estimated weight of your model as well as where the CG is. Then we moved into SolidWorks to model everything else. In the end, we got these fancy graphs and we knew the shape of everything and where it needs to be:

After that, we added a tail to the simulation and moved it around until the pitching moment was looking right. So we experimented with wing size, chord length and other airfoils until we found the highest coefficient of lift to drag ratio. and it showed that the airfoil we choose wasn’t the best. A simulation was run with the previously stated constants like cruise speed, weight etc. There is also Aeolus, but we haven't tried it yet.Īn airfoil that looked like it could be good was chosen from the airfoil database and the wing size was chosen to be 2m.

It is a free airfoil and wing design and simulating app that we have been using for a while now. To choose the wing characteristics we go to our good friend XFLR5. We overcome the stability issue by adding a small motor on the tail for pitch and yaw control during take-off and we ignore the lift problem as it doesn't look too significant. Tilt wing configuration comes with flaws too, the main one being stability and lift generated from the motors pointing backwards during take-off. It was chosen because not a lot of teams do it and it offers interesting advantages compared to other VTOL configurations: in configurations where all motors rotate, you need a servo for each motor, whereas we only need 1, configurations with a fixed quad frame for take-off and a separate motor for cruise suffer from increased drag. We decided to try an unusual VTOL configuration that involves the whole wing with the attached motors tilting. The competition is relatively open in terms of design requirements, with the main one being mass less than 10 kg, travel distance of about 1km and max speed below 60m/s.Īfter a lot of discussions and arguments, we decided to go with a 6kg VTOL plane with a 2kg payload with a cruise speed of 20 m/s. First off, to design the drone we had to choose what we wanted our drone to do.
