Wait...this is considered a doujinshi? I figured it was an official publication rather than self published since this was packaged with my Simoun PS2 game that came out years ago.
Those flying vehicles are called "Simoun" which this publication is based on. The term "helical motor" is the spherical object in the Simoun that helps the aircraft to fly.
This particular manga storyline is parody based and was published by Marvelous Entertainment who also produced and published the official PS2 game. And it was included if you purchased the limited edition game box set.
