Racetrack winders

Another type is known as the orbital, or racetrack winder, where the winding heads move completely aroimd the mandrel, as shown in Figure 21. It is used primarily for rocket motor cases and where polar winding is desired high speed is attainable. 

Very small to large filament wound cases have been fabricated for use on rockets and missiles. As an example, a racetrack filament winding RP fabricating technique was used to fabricate a very large tank (rocket motor case) for NASA. See Chapter 5 Filament Windings, Racetrack and Other Winders.
