What does CFM stand for in jet engines?
So, Commercial Fan Motor = CFM. CFM International (CFM) is most well-known for producing the CFM56 and the newer LEAP engine families, which power thousands of Airbus A320 and Boeing 737 aircraft worldwide. The program was saved when Delta Air Lines, United Airlines, and Flying Tigers chose the CFM56 to re-engine their Douglas DC-8 aircraft as part of the Super 70 program. The first engines entered service in 1982. The CFM56 was later selected to re-engine the Boeing 737.The two companies initially developed the CFM56 product line that would go on to become the best-selling aircraft engine in commercial aviation history. The engine family brought operators industry-leading reliability, fuel efficiency, lower noise and emissions, and overall cost of ownership.Since 1984, CFM has provided the sole powerplant for all Boeing 737 models from the Classic 737-300/-400/-500 to the Next-Generation 737-600/-700/-800/-900/-900ER and the BBJ.
What is the CFM of the A320 engine?
The first A320 entered service powered by the CFM56-5A engine in 1988. In 1994, CFM expanded the thrust range from 22,000 to 33,000 pounds (97 to 147 kN) thrust with the introduction of the CFM56-5B. A strategic alliance. The CFM56 engine is the result of a 50/50 partnership between Safran Aircraft Engines and GE Aviation called CFM International. The two companies are equal partners in the design, development and production of the engine.Both companies have their own final assembly line, GE in Evendale, Ohio, and Safran in Villaroche, France. The engine initially had extremely slow sales but has gone on to become the most used turbofan aircraft engine in the world. The CFM56 first ran in 1974.The world’s best selling engine in aviation history The CFM56®, developing 18,500 to 33,000 lb of thrust, set a standard in this market.CFM56 and LEAP engines are products of CFM International, a 50-50 joint company between GE Aerospace and Safran Aircraft Engines.
How do you calculate CFM?
CFM Formula Use the formula below to calculate CFM: CFM = (Room Volume in cubic feet) x (ACH) / 60. HVAC professionals use this formula: CFM = Room Area (sq. Ceiling Height (ft. ACH / 60(mins).CFM is an acronym for Cubic Feet per Minute which measures the volume of air, in cubic feet, for each minute it moves. In the case of an air compressor, CFM indicates how much air can move per minute. For example, an air compressor’s output rated for 30 CFM means 30 cubic feet of air flow per minute.
Is 400 CFM equal to 1 ton?
In our opening statement we quoted a rule-of-thumb about air conditioning requiring 400 CFM per ton. This value is usually the basis for rating self-contained air conditioners. Thus, we have a 2-ton unit handling 800 CFM, a 3-ton 1,200, a 5-ton 2,000, a 10-ton 4,000, etc. Now, let’s discuss the ‘1 TR = 400 CFM’ rule. This rule is a generalized rule of thumb in the HVAC industry. It suggests that to effectively remove one ton of heat (1 TR), an HVAC system should be able to move approximately 400 cubic feet of air per minute (400 CFM).
