What type of wheel assembly includes a demountable flange?

The type of wheel assembly that includes a demountable flange is accurately described by the option referring to a demountable flange. This type of wheel assembly is designed to facilitate the easy removal and installation of tires, allowing for quick maintenance and replacement without requiring specialized tools or equipment.

The demountable flange is typically secured in a way that allows it to hold the tire in place while also providing the ability to detach it when necessary. This is advantageous in aviation and other high-performance sectors where rapid turnaround times for maintenance can be critical.

The other types of wheel assemblies do not incorporate this feature. Solid rims, for instance, are constructed as a single unit and do not allow for the separability of components in the same way. Likewise, split rims have a construction that allows for tire removal, but they typically do not include a demountable flange in their design. Non-removable flange assemblies would not allow for easy tire changes, making them less functional in applications requiring flexibility and efficiency.
