Help "selling" animated things

Hey all,

I’ve been working on a big project lately (an aircraft) but I’ve ran into a problem. The project relies on a lot of animations, but I don’t know how to make the animations so that anyone can use them. I’m planning on selling the aircraft to other people, and it wouldn’t be very viable to have everyone upload each and every animation themselves. There are many other animated planes on the market, so I was wondering how they are able to make animations everyone can access.

Does anyone know any possible solutions? If so, that would be great.
