Overview for CargoHopper
Update submission, May 28:
Reason for update: see comment in my blog.
As safety is most important. here is a summary of the different fail safe modes:
1. If one forward thrust motor fails, the CargoHopper can use the second forward thrust motor to proceed to a safe landing site.
2. The CargoHopper has landing gear and can land in forward flight motion.
3. If a vertical motor fails, the CargoHopper can land vertically with 2 vertical lift propeller/motors, keeping stable control with yaw, pitch and roll control provided by the forward thrust propellers and air flow over the vertical and horizontal stabilizers.
4. An emergency parachute can be deployed in case the previous 3 fail safe modes can not be used.
The design concept is described in the following file:
