Area Misting Nozzles

Custom Solutions Bulletin 038
Application #040240
Industry: Aerospace
Application: Area Misting
Product Description: Special XA Manifold


A BETE customer was designing an "Icing Wind Tunnel" to study the effects of droplet size and droplet density on the formation of ice build-up on airplane wings. Drop size and water flow rate had to be independently variable covering 15-70 um and 0.47-1.58 gpm. Even coverage was required, and an "aerodynamic shape" would be desirable.


Due to the requirement for independent variability of flow and drop size, an air atomizing misting nozzle was the obvious choice. When the customer expressed an interest in a controls system to regulate the nozzles, BETE Applications Engineering provided a quote for the design and fabrication, which was accepted. The final solution included 5 XAAD250 setups in a custom manifold made from a solid piece of gun-drilled bar stock to provide low wind resistance and ease of fabrication.
