Unique Application; "Projection" Spray Nozzle Source?

Greetings,
See the attached sketch.

I'm going to vastly simplify things to get down to the question.

I'm tasked with finding a nozzle (or nozzles) capable of "squirting" a fluid (lets assume its water) out to a distance of about 10 feet in a fairly uniform "flat" pattern. The contact area could be flat or have an arc as shown in the sketch. I'd like the keep the nozzle as close to parallel with the ground as possible. Ideally it would achieve 30 - 50 gpm. The pressure could vary as needed to get the required performance,

I am looking for someone who makes "squirting" or "projection" spraying nozzles, or even a proper term for such nozzles?

I have contacted several manufacturers of spray nozzles but they are all design to spray straight down and they've got no experience squirting outward.

This should not be too complicated, as I can go get a fan-type el-cheapo garden nozzle and do basically the same thing in my front yard. However, I am looking for something that has a better flow-rate, can handle more pressure and take more of a beating than a garden nozzle. I assume there are companies out there that specialize in these types of spraying applications, I just cannot find them. A lot of the irrigation systems project water out but I have had trouble finding a supplier for this type of nozzle.

Does anyone have any suggestions?

Spray.com was one of my first stops. They basically told me I was crazy and that I should design a rig on which I can place nozzles that are facing straight down.

I think "Boomless Flat spray nozzle" is probably the relevant term. I'll keep digging but its looking more and more like I'm just going to have to end up doing trial-and-error with fountain nozzles. Possibly even make our own If nothing else.

Still open to suggestions.
Thanks everyone for your contributions,

To make such a spray pattern you start with a nozzle that forms a straight jet of water which then impacts a plate at an angle to cause the jet to fan-out. Placing edge dams on the plate will help to create a sharper edge to the spray pattern. If you make the geometry adjustable you can get any pattern you want, like putting your thumb over a garden hose.
