A motor controller known as a variable frequency drive (VFD) controls an electric motor by adjusting the power supply’s frequency and voltage. The VFD may also regulate the motor’s ramp-up and ramp-down during start and stop, respectively.
Many different kinds of vehicles, such as airplanes, airships, hovercrafts, and powered lift VTOL aircraft, use fans for propulsion or direct lift. A very successful and well-liked application of ducted fan design is the high-bypass turbofan engines seen on many contemporary airplanes.
The global aircraft variable frequency fan market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Astronics Corporation, a major supplier of cutting-edge technology to the global aerospace, defense, and other mission-critical industries, announces the launch of the new CorePower Frequency Converter Unit (FCU).
The new device, made available by Astronics AES, a fully owned subsidiary of Astronics, transforms variable frequency power sources into constant 400 Hz electricity to safeguard delicate aviation electronics from unregulated frequency and power surges.
The CorePower FCU adapts to the latest developments in airplane power systems, which use variable frequency (VF) generators rather than fixed frequency (400Hz) generators. Even though the bulk of aircraft loads can operate on VF power, some loads still need 400Hz. The FCU converts variable frequency 3-phase 115VAC input power (324 Hz to 800 Hz) to constant frequency 3-phase 115VAC output power (400Hz) for pure, efficient power.
This Safran Cabin AS1308A02 fan includes three phases, 115 VAC, 360 to 800 Hz, variable speed, and axial flow. It is used to extract air from the area in the aircraft’s back. Three-phase 115Vac/Variable frequency, 470 W of power at operating point, 150 litres per second of flow, 15 hPa of pressure, and 7.1 kg of weight.
Avionics and the aeroplane cabin are ventilated by the Safran Cabin AE1812A00 variable frequency fan. Air is drawn across the brakes of passenger jets and commercial airliners using Super Vac’s Aircraft Brake Cooling Fan, which is a specialised device made to speed up turnaround.
The fan’s unique seal makes contact with the plane’s wheel, and a precisely engineered impeller draws cool air through the wheel assembly to evenly cool the braking system. The A320, A380, or B787 can all use Super Vac’s fixed-height Aircraft Brake Cooling Fan (or other custom heights). To span all of the aforementioned aircraft, this aircraft brake fan is also available with an optional lift.
The portfolio of Diehl Aviation includes electrically powered variable high speed fans with a broad frequency range of power supply that circulate air from the cabin to the aircraft’s air conditioning system. Devices with a 15 kVA power requirement and a volume flow of 1.100 l/s can rotate at speeds of up to 40.000 rpm.
The majority are designed using a 4-pole permanent magnet synchronous brushless motor and an axial flow in-line fan. The embedded software regulates the fan speed, uses the CAN Bus to connect to the aircraft ECS system, and has capabilities for health and failure monitoring.
