Figure 1: Components of a centrifugal fan An external motor belt driven inline centrifugal fan discharging inline to the exterior of a building through a duct. Unlike non-inline/non-concentric impeller casing design with a cutoff blade above, the concentrically symetric cylinder casing and impeller geometry of inline type redirects the outflow around so that it is parallel to the inflow of gases.
The company developed a new fuselage for the TNT and TPE 331–5 in two variants (15- and 19-passenger) and named both project-aircraft E-1 (later Dornier 228-100) and E-2 (later Dornier 228-200). At the ILA Berlin Air Show in 1980, Dornier presented the new aircraft to the public. Both of the prototypes were flown on 28 March 1981 and 9 May ...
Attaching an internal fan to a motor is a fairly simple way to cool it. Since a fan cooled motor always provides airflow over itself regardless of whether it is stationary or partially enclosed, it is more effective than using a heat sink in applications with poor airflow because heat sinks usually require air to be flowing over them for maximum effectiveness.

The Emrax 228 is a brushless 130 volt design producing a peak of 100 kW (134 hp), 55 kW (74 hp) continuous, with an outrunner coil. It has a 98% efficiency. It has a 98% efficiency. The low working rpm of the engine means that it can turn a propeller at efficient speeds without the need for a reduction drive .
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 ...
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 ...
