Have a look at this nice rig of what looks like a modified jetpack from Titanfall 2. Done by an artist known as UzuriderXD using Blender, these movements are really satisfying to look at, all smooth and sleek.

UzuriderXD surely loves Titanfall, and there are lots of renders of the character's suit and some assets on X/Twitter.
Whether you like the game or not, I think you should follow the creator to see how this journey ends and maybe learn something for yourself.
