I am working in a 10 person group on a project in Aero E. Long story short its a two semester project, first semester we came up with a design for a full scale VTOL Tilt-wing 4 person flying car. This semester, one of our main tasks is to build a functioning "demonstrator" model of our design. The purpose is not to be as close to our full scale as possible, but just to demonstrate important aspects of our design.
While we have a number of great engineers in the group, we have very little model aircraft experience among us. I myself have flown numerous models owned by my GF's dad who is into the hobby on a dozen or more occasions, but the only thing I've built is a 450 quad that I finished this week actually. We have a couple other guys who have flown small planes and helicopters before, but nothing close to this scale and complexity.
We'd like to build a model with 3' wingspan and functioning tilt wing for vertical takeoff and to transition to forward flight. We're trying to figure out exactly how to design the model to accomplish this, and this is where I have questions for you guys.
Here is a solidworks version of what we envision for the model. http://i.imgur.com/xSZOI2W.jpg
We have since revised this to have a smaller fuselage, but I don't have that version on me now. Our full scale design has just two engines on the wingtips. For the model, we are considering adding a small motor/servo to the tail for yaw control and better pitch stability, essentially making it a tricopter in vertical flight. We don't intend to do much maneuvering or flying in vertical, only enough to get high enough to transition to forward, and then to transition back to vertical to land. In forward flight, we will have traditional plane control surfaces controlled by servos.
1) Do you see any major problems with this plan?
2) Is arducopter the right choice for this project? Will we need to do custom programming of the flight controller to accomplish this, and if so, where is the best place for info on how to do that? What about transmitter/receiver? What would you recommend for a receiver/transmitter?
3) What is the best way to mechanically accomplish tilting the wing? Is it possible to do with the wings attached in the middle of the fuselage as pictured?
4) Good way to mount motors to the wingtips? I believe we are strengthening the wings with aluminum spars, how can we effectively mount to aluminum?
We have a lot of equipment and budget at our disposal, we have a big 3d foam cutting machine for the fuselage, wings, etc. Any more advice that you can offer? Is there somewhere else I should post this?
