No power is transmitted through the gearbox gears unless an engine is shut down. Engine mounts are not critical in the Genesis design since the engines are in the fuselage and do not support the propellers. The drive pulleys are supported by their own bearings. The Genesis engine mounts are not likely to fail since prop imbalance does not fatigue the mounts as in conventional designs. The drive belts are not critical since there are three belts in parallel between each set of pulleys.
Any drive belt can fail and the other two in the set are capable of handling the load.
The three belts in any set are separated by partitions which prevent a failed belt from becoming entangled with any other belt. The high reliability of drive belts is well known. Failures of these components occur from misalignment, contamination, and shock loads. Alignment and lack of contamination are guaranteed by our design. The wing extension system is redundantly actuated and has no critical components other than the structure itself, which in cruise, is much stronger than conventional designs .
