DUCTED FAN Meaning and
Definition
-
A ducted fan refers to a type of propulsion system that operates by generating thrust through the rotational motion of a fan enclosed within a duct. It is commonly used in various transportation vehicles such as aircraft, rotorcraft, and unmanned aerial vehicles (UAVs). The duct surrounding the fan serves the purpose of focusing and directing the airflow, resulting in enhanced efficiency and improved performance.
The ducted fan consists of multiple blades, typically made of lightweight materials like carbon fiber, arranged radially around a central hub. This setup enables the fan to generate highly pressurized air and direct it in a controlled manner. The duct, which encases the fan, allows for better management of the airflow and reduces the effect of airflow separation. By confining the airflow within the duct, the generated thrust is intensified while noise and external disturbances are minimized.
The use of ducted fans offers several advantages over conventional propeller systems. These include increased aerodynamic efficiency, reduced noise levels, improved safety by enclosing rotating parts, and the ability to efficiently operate in confined spaces. Additionally, ducted fans provide better control during low-speed maneuvers and vertical takeoff and landing (VTOL).
Ducted fans are commonly employed in applications requiring a combination of high thrust, compact size, and maneuverability. They find use in various contexts such as military drones, hovercraft, small aircraft, and even personal air vehicles. The versatile nature of ducted fans has made them a crucial component of propulsion systems, particularly in situations that necessitate optimal thrust performance with minimal noise and enhanced safety.

Etymology of DUCTED FAN
The word "ducted fan" is composed of two components: "ducted" and "fan".
The term "ducted" refers to the presence of a duct, which is a tube or channel that is used to guide or direct the flow of fluid. In the case of a ducted fan, this refers to the presence of a housing or shroud around the fan blades, which are enclosed within the duct.
The word "fan" comes from the Old English word "fann", which is derived from the Latin word "ventilare", meaning "to winnow" or "to fan". The concept of a fan has been used for thousands of years, initially referring to a hand-held device used to create a current of air. Over time, the term "fan" has also been applied to mechanical devices for moving air or other fluids.
