2. Propelling nozzle - Wikipedia

   en.wikipedia.org/wiki/Propelling_nozzle

   The amount of this air varies significantly across the flight envelope and ejector nozzles are well suited to matching the airflow between the intake system and engine. Efficient use of this air in the nozzle was a prime requirement for aircraft that had to cruise efficiently at high supersonic speeds for prolonged periods, hence its use in the ...

3. Ducted propeller - Wikipedia

   Kort nozzle The towboat Dolphin I in a floating drydock on the Mississippi River in Algiers, Louisiana. A ducted propeller, also known as a Kort nozzle, is a marine propeller fitted with a non-rotating nozzle. It is used to improve the efficiency of the propeller and is especially used on heavily loaded propellers or propellers with limited ...

4. Plug nozzle - Wikipedia

   en.wikipedia.org/wiki/Plug_nozzle

   Typical plug-nozzle garden sprayer with a trigger-pull lever (at the back) to control the position of the plug and valve. Common garden hose trigger nozzles are a simple example of the plug nozzle and its method of operation. In this example the nozzle consists of a conical or bell shaped opening with a plug on a movable rod positioned in front ...

5. Turboprop - Wikipedia

   The turboprop system consists of 3 propeller governors, a governor, and overspeed governor, and a fuel-topping governor. [14] The governor works in much the same way a reciprocating engine propeller governor works, though a turboprop governor may incorporate beta control valve or beta lift rod for beta operation and is typically located in the ...

9. Nozzle and flapper - Wikipedia

   en.wikipedia.org/wiki/Nozzle_and_flapper

   The example shown is pneumatic. At sub-millimeter distances, a small movement of the flapper plate results in a large change in flow. The nozzle is fed from a chamber which is in turn fed by a restriction, so changes of flow result in changes of chamber pressure. The nozzle diameter must be larger than the restriction orifice in order to work. [2]
