Visby water jet details?

dhanners

I'm wondering if anyone might know where I could find some decent online photos and/or diagrams of the external portions of the water jet propulsion system used on Sweden's Visby-class stealth corvettes. I'm building a 1/200th-scale card model of the Visby, but the model has simplified parts for the external portions of the water jets; they are basically just open rectangular boxes.

I've spent a few minutes searching the Tubes of the Internets but haven't been able to find any decent photos or diagrams. I was hoping some of the naval experts here might know something....

Thanks.

 

I google images using 'Visby pump jet' and got a hit on this.   It doesn't seem to want to link into the image function of the page  ... go here and surf around.

It isn't the Visby,  but naval pump jet technology is fairly standard.   Think jet ski on steroids.

There is a venturi cone which penetrates the hull  It is a 'flow enhancer'.   Outboard of the cone is a box-shaped control device.   It has a flow director gate.   There are external hydraulic jacks which control the postion of the gates

Thanks, Ed. The one photo I've been able to find of Visby's "waterjet propulsion buckets" are from the rear, but the detail I can discern look much like (if not exactly like) the ones in the photo you linked to. Absent any more info that I might come across, I think I'll just scratchbuild those.

Dang. I was hoping this would be a relatively quick build....

Thanks, though. The link is very  helpful.
