It’s still a modified fog line. Droplets of water move air. We can entrain air with a solid bore nozzle moved around in o and a patterns. We can get conventional fog nozzles that run at 50 psi with low back pressure. We can get solid bore lines that will open to really good fog patterns. None of which are really going to be used in mocking down a structural fire. A bladed stream is still a flat fog that when spun around entrains as much air as any other broken stream. To think this is a stream without air entrainment for those looking at it as such, is foolish at best. So if we are going to reduce the amount of air entrainment during attack and a solid bore provides the best ability to reduce that. Then I fail to see what problem this is trying to correct.

It’s still a broken stream. Water droplets entrain air. Moving the nozzle increases the entrainment. It’s still an attempt to create a better fog nozzle. The NIST UL studies pretty much spell out the science.

The HEN Nozzles TURBO BPI is A Revolutionary Advancement, Disassociating Nozzle Pressure from Back Pressure. We have been working on this for a while, get 160gpm@50psi a 60lbs Nozzle Reaction and a 75psi hose Back Pressure, now that sounds like heaven, because it is: Stay up to date on what's now possible, from rig to nozzle, and pattern to seat. HEN is Building the Most Advance & Balanced Handline Attack Package Systems in the World. Back Pressure vs Nozzle Reaction GPM & Pattern Types. A New Trifecta is Now Possible From Pump Operator to Back -up to Nozzles. TURBO Charge All 1.75-inch Handlines with 50psi Nozzles Pressure The Turbo between 150 to 185 gpm, increases Back Pressure an additional 25 to 30psi in the handline stretch from Rig to Nozzles on top of the 50psi Nozzle Pressure in both Flowing and non-Flowing Conditions. Boost 1.75-inch hose performance when using a 50psi NP with impressive benefits in all essential metrics from Higher Pressure Hose to Premium Low-Pressure hose design. Streamline essential members tasks in handline fire stream development on the fire ground, while enhancing suppression and safety: Pump Operator: 1) Higher Initial PDP = Less Kinks On-Charge 2) Simplifies all Transfers to Positive Pressure Source (Tank to Hydrant Transfer & Booster Back-up) 3) No to Less Gating Discharges 4) Governor Functions as Designed when Net Pump Pressure < Discharge Pressure Back-up(s): 1) Entire Stretch Possesses a Back Pressure Enhancement from Rig to Nozzle 2) Appropriately Rigid Line is easier to Feed and Push on Advance 3) Appropriately Rigid Line is easier to Pull on Advance 4) 75psi BP = Less Kink Formation in the IDLH and Outside Nozzles: 1) Achieve proper NP quicker upon call for Water, more Mechanical Force Knocking Dry Kinks Out 2) Reduces to Eliminates Hose and Nozzle Whip Issues 3) Ensures an Arm Length Nozzle Bite, Improving Water Mapping with Less Arm Movement 4) Low reaction force 50psi Nozzle Pressure remains intact.

That was just a demonstration of Fountain Statue Firefighting. You don't squirt water on one spot endlessly and call that firefighting.
