The challenge

The tires of the airplanes are not rotating at a touchdown (when landing). As a result, they have to skid/slide until their rotational speed matches the velocity of the airplane, leaving dark spots on the runway, damaging the tire. This is the main reason you see smoke come out of airplane tires when you watch airplanes land.

The solution

Using an electric motor with a very simple design (in order to avoid problems when getting certifications required) which can be added to the axial of the landing gear (so it is not needed to redesign the whole landing gear since this is only an addition). This will then pre roll the wheels before the touchdown happens. Furthermore, there won't be any gyroscoping effect and not much energy will be needed (main arguments that people bring up) since this will start working right before the landing.

Mission

Make the airplane wheels spin right before the touch down.
