The AMCA inside Technical Seminar provides engineers with basic information regarding devices and engineering principles relevant to the air movement and air control industry. The Engineering Conference is a discussion forum for presentation of engineering papers written by engineers and experts in the air movement and control industry.
An axial fan is a type of fan that causes gas to flow through it in an axial direction, parallel to the shaft about which the blades rotate. The flow is axial at entry and exit. The fan is designed to produce a pressure difference, and hence force, to cause a flow through the fan. Factors which determine the performance of the fan include the ...
A household electric fan A large cylindrical fan. A fan is a powered machine that creates airflow. A fan consists of rotating vanes or blades, generally made of wood, plastic, or metal, which act on the air. The rotating assembly of blades and hub is known as an impeller, rotor, or runner. Usually, it is contained within some form of housing ...
NASA Systems Engeering Handbook SP-601S: "This handbook is intended to provide information on systems engineering that will be useful to NASA system engineers, especially new ones. Its primary objective is to provide a generic description of systems engineering as it should be applied througout NASA." Date
A fan wiki is a wiki created by fans of a popular culture topic. Fan wikis, which are a part of fandoms, cover television shows, film franchises, video games, comics, sports, and other topics. The primary purpose of a fan wiki is to document its topic area through collaborative editing. Fan wikis document their subjects at varying levels of detail.
The affinity laws (also known as the "Fan Laws" or "Pump Laws") for pumps/fans are used in hydraulics, hydronics and/or HVAC to express the relationship between variables involved in pump or fan performance (such as head, volumetric flow rate, shaft speed) and power. They apply to pumps, fans, and hydraulic turbines. In these rotary implements ...
A turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft propulsion.The word "turbofan" is a combination of references to the preceding generation engine technology of the turbojet and the additional fan stage.
Diagram of a fan disk Fan disk assembly diagram, showing one blade and attachment hardware Cross section of fan disk Failed fan disk recovered from the center engine of UAL 232. A fan disk is the central hub of a fan in a turbofan engine. Fan blades are attached to the fan disk, which is rotated by a shaft driven by a gas turbine. [1]
