1. A nose gear spin down apparatus, comprising:
a spin down device rotatable about a central longitudinal axis, wherein the spin down device rotates about the central longitudinal axis at a first speed after engagement with a spinning nose gear wheel of an aircraft that spins at a second speed;
the spin down device comprising:
a tubular casing comprising internal threads; and
a threaded shaft positioned within the tubular casing and comprising external threads engaged with the internal threads of the tubular casing; and
a resistance device distanced from the spin down device by a space;
wherein the resistance device imparts a resistance to the spin down device when movement of the threaded shaft relative to the tubular casing along the central longitudinal axis or movement of the tubular casing relative to the threaded shaft along the central longitudinal axis causes the threaded shaft or the tubular casing to move through the space and into contact with the resistance device.
