Fuel flow to the fuel nozzles is controlled by a hydromechanical fuel control unit (HMU) in response to power requirements and flight conditions.
The HMU can be used in manual mode or EEC mode (electronic engine control) (manual pilot input). The de-icing and pressurisation systems also get bleed air from the engine.
The fuel pressure at the nozzle can change as the burner or compressor discharge pressure changes thanks to a bellows-actuated burner pressure sensor valve that is located between the throttle valve’s discharge side and the fuel pump’s intake side.
Global aircraft hydromechanical fuel control system market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
The company’s Allen Aircraft division will be the only distributor of Honeywell’s Hydro Mechanical Unit (HMU) for the CFM56-7 engine, according to Honeywell.
The Honeywell HMU is designed for the CFM56-7 engine and controls how much fuel is given to the engine as needed during engine operation.
The “next generation” Boeing 737 is propelled by a CFM56-7 engine. These 737s are now in service in about 480 units, and 887 more are ordered for the 737’s next generation.
The best distributor for this item is AAR Allen Aircraft because of their extensive global networking, distribution, and logistical capabilities.
The leading supplier of goods and value-added services to the global aerospace/aviation sector is AAR CORP.
Products and services range from the supply, maintenance, and production of replacement parts and systems to specialised inventory management and logistic support services.
The Saab-Fairchild 340’s engine is managed by hydromechanical and electrical components.
The location of the engine power and condition levers on the flight deck, the gas-generator speed, the compressor output pressure (P3), and the compressor temperature (T2) all affect the pressure at which the hydromechanical unit (HMU) distributes fuel to the injectors (Ng).
