Flange fittings are generally used for connections to valves, inline instruments or equipment nozzles. When water is pressurized through the main pipe it escapes from the rotating nozzles. Liquids are encapsulated by a rotating head containing concentric nozzles. It consists of a tower with spray nozzles, which generate the droplets for surface contact. The movements of the engine nozzles are controlled by four hydraulic actuators. Turbine blades are of two basic types, blades and nozzles. There is a wide variety of spray nozzles available for use in electrostatic coating. Hair dryers are available with attachments, such as diffusers, airflow concentrators, and comb nozzles. The fluid is dispensed through small nozzles mounted on the hood. It consists of alternate rings of nozzles and turbine blades. The very narrow inkjet nozzles are prone to clogging. The Su-47 has two tailbooms of unequal length outboard of the exhaust nozzles. The engine's thrust is directed through the four rotatable nozzles. The fuselage extends almost entirely up to the engine's exhaust nozzles. Two pairs of ducts fed the aft-pitch yaw nozzles and the forward-pitch nozzles.
