Drawing the Nose Gear and its Associated Mechanism in CAD took several weeks.
The landing gear is extended and retracted via a worm gear drive. The drive is powered by an electric motor through a complex reduction and differential gearbox that also operates the main landing gear.
Building this gearbox, especially the production of the gears for the differential gearbox, the worm, and the worm wheel, is quite a challenge. These parts will need to be manufactured by a company specialising in such components, which still needs to be found.
Additionally, the gearbox presented various issues during the test flights. For this reason, I am considering completely redesigning the system.
One alternative could be a construction using a link lever and a hydraulic cylinder. However, positioning the components in the available space is not trivial. After numerous attempts, the solution shown below turned out to be the only feasible one.
The forces involved have all been calculated, and the components are accordingly sized.
If switching to a hydraulic landing gear system, the worm gear in the main landing gear would also need to be replaced with a hydraulic cylinder. Whether this is feasible is something I still need to figure out.
