Tiltrotor "Krakozyabra" - 4 propellers

I wanted to make another joke about the topic of convertiplanes.I wanted to imagine the scope and complexity of solving this problem.This is a problem of energy, stability (controllability) and the problem of sufficient strength with limited mass.I did not try to solve these problems - only to imagine.For myself, I came to the conclusion that the complexity and cost of solving these problems exceed the actually achievable result.I made models in 2 versions of the propulsion system: propellers and impellers. When designing the impellers, I used the help of AI Chat GPT.Conventionally, this aircraft is intended only for experimental purposes. Short-term test flights only near their airfield. Flight time is limited by the capacity of the batteries.A specific model (As Is) is fantasy and improvisation. When possible, I used ready-made components. An unmanned version is possible.If someone wants to try to solve this problem - Good luck!
