What aircraft is a CFM56 5B?
CFM56-5B/-7B CFM56 engines are used in the twin-engine Airbus A320 family, in the first generation of the A340-200/-300 long-haul jet, and in the Boeing 737 Classic and 737 Next Generation. Since its introduction in the 1980s, the CFM56 engine product line has continued to serve as the industry benchmark for single-aisle commercial jet engines in terms of reliability, fuel efficiency, time on wing, and overall cost of ownership.The CFM56 engine can stay on wing for as many as 20,000 cycles, with an average time on wing (TOW) of 18,000 cycles to its first overhaul; that’s approximately nine years without removing the engine for heavy maintenance [see time to first shop visit chart below; TOW data accumulated from CFM’s Fleet Data Management ( .
What do CFM engines stand for?
CFM means CFM International (CFM), which is a joint venture between: GE Aerospace (United States), and, Safran Aircraft Engines (formerly Snecma, France) The name CFM comes from the combination of: CF for the CF6, a GE engine program – CF stands for Commercial Fan. It was introduced as part of GE’s engine . Capital Fund Management S. A. CFM SA”) is a French company incorporated in the form of a société anonyme (RCS Paris B 395 083 504), having its registered office at 23, rue de l’Université, 75007 Paris, France.As a 50/50 joint company, CFM’s financial and shareholder information is reported through our parent organizations – GE Aerospace and Safran Group.
What is the CFM56 engine used for?
The CFM56 is the world’s most widely used turbofan in commercial aviation. The CFM56 powers entire lines of commercial jets made by Airbus and Boeing to include the A3XX series and B737 family of aircraft with operators worldwide. The CFM56-7B series uses a standard two-shaft design with a 61-inch diameter fan. Behind the fan is a three-stage low pressure compressor (LPC), a nine-stage high pressure compressor (HPC), a one- stage high pressure turbine (HPT), and a four-stage low pressure turbine (LPT) to drive the fan and LPC.The CFM56 is a high-bypass turbofan engine (most of the air accelerated by the fan bypasses the core of the engine and is exhausted out of the fan case) with several variants having bypass ratios ranging from 5:1 to 6:1, generating 18,500 to 34,000 lbf (80 kN to 150 kN) of thrust.The CFM56-2 comprises a single-stage fan with 44 blades, with a three-stage LP compressor driven by a four-stage LP turbine, and a nine-stage HP compressor driven by a single-stage HP turbine.
What does CFM stand for in aviation?
CFM is an acronym for Cubic Feet per Minute which measures the volume of air, in cubic feet, for each minute it moves. CFM stands for Cubic Feet per Minute, a measurement of airflow used in HVAC systems. It indicates the volume of air that is delivered or circulated by the system each minute. Proper CFM levels ensure adequate ventilation, comfort, and energy efficiency in heating, cooling, and ventilation systems.Multiply the room’s floor area by the ceiling height to obtain the volume. Multiply the volume by the recommended air change per hour (ACH) of the room. Finally, divide the result from step 2 by 60. The result is the airflow of the room in CFM (cubic feet per minute).As mentioned above, cubic feet per minute is a measurement used to describe airflow. The number represents the volume of air moved through a given space every minute. To calculate CFM, multiply cubic feet by 60 seconds. So, for example, a fan moving 1 cubic foot of air per second would be equal to 120 CFM.CFM Formula. Use the formula below to calculate CFM: CFM = (Room Volume in cubic feet) x (ACH) / 60.
What does CFM56 stand for?
CFM is not an acronym, so it doesn’t stand for anything. The company (CFM), and product line (CFM56), got their names by a combination of the two parent companies’ commercial engine designations: GE’s CF6 and Snecma’s M56. CFM is the world’s largest commercial aircraft engine manufacturer, with a 39% market share as of 2020. It has delivered more than 37,500 of its engines to more than 570 operators. The name CFM is derived from the two parent companies’ commercial engine designations: GE’s CF series and Snecma’s M series.The whole engine parts cost more than $3m, $3. By June 2019, the CFM56 fleet had surpassed one billion engine flight hours (nearly 115,000 years), having carried more than 35 billion people, over eight million times around the world.
How many CFM is in 1 ton?
CFM per Ton Rule of Thumb It suggests that for every ton of cooling capacity provided by the air conditioner, approximately 400 cubic feet per minute (CFM) of airflow should be delivered to the conditioned space. 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.A typical central AC unit or heat pump can produce an average of 400 CFM per ton of air conditioning capacity. So, as an example, a 1,200 CFM requirement would mean you need a 3-ton HVAC system.
