As of, there are four major variants of the engine, each with multiple sub-variants. If operational requirements dictate, the engine may be shut down with a one minute cooling period. After shutdown, monitor EGT and engine rpm, to be sure that the temperature and rpm decrease, indicating fuel shut. Discover how the CFM56 engines are assembled in Snecma’s pulse line at Villaroche, France.
military designation F108) series is a French-American family of high-bypass turbofan aircraft engines made by CFM International (CFMI), with a thrust range of 18,500 to 34,000 lbf (82 to 150 kN). and others in France. See full list on military. training, go to the Pilot Center on our website, deltva. In 1989, CFMI began work on a new, double-annular combustor. Airstarts in most of the starting envelope require starter assist due to the low windmilling characteristics of the engine. Two spool,13 stage compressor consisting of a 4 stage low pressure compressor (includes 1 stage fan) and a 9 stage high press compressor.
Warning: Be prepared to abort the start if a rapid EGT rise occurs, approaching starting limits -Li. Continued development. If the engine operates normally at idle, it should be allowed to idle for 3 minutes prior to shutdown if practical.

Use alternate ignition system for second start cfm56-7b manual attempt. Subtask, of Task, from the CFM56-7B ESM, describes procedures for performing an eddy current inspection (ECI) of the affected fan blades. Most variants of the CFM56 feature a single-annular combustor. SNECMA, who had mostly built military engines until then, was the first company to seek entrance into the market by searching for a partner with commercial experience to design and build an engine in this class. .
In 1987, a double flameout occurred in hail conditions (the pilots managed to relight the engines), followed by the TACA Flight 110 incident in 1988. NOTE: IF ENGINE FLAMEOUTS OCCUR. Increasing kias will increase windmill speed. . Hot Starts may be caused by : (a) Inadequate starter air pressure, resulting in N2 too low to provide sufficient compressor air flow. 004 CFM International CFM56-7B series engines, -. (b) Faulty starter valve action, preventing proper operation of starter, with same result as item (a) (c) Premature starter deactivation (d) Incomplete purging of fuel in the comb. Air entering the engine are divided into a primary (inner) airstream and a secondary (outer) airstrea.
Airstart attempts may be made following a voluntary shutdown at any altitude and airspeed; however if the start cannot be achieved, establish flight conditions within the airstart envelope. Cfm56 7b Training Manual CFM56-7B Training Manual. See Chapter 5 of the CFM56-7B Engine Shop Manual CFM-TP. The CFM56-3 is a high bypass, dual rotor, axial flow turbofan engine. Department of Transportation Federal Aviation Administration 800 Independence Avenue, SW Washington, DCtell-FAA.
10** Revision 074 - Non-Destructive Test Manual NT. The CFM56 is a high-bypass turbofan engine (the majority 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 ratiosranging from 5:1 to 6:1, generating 18,500 to 34,000 lbf (80 kN to 150 kN) of thrust. Instead of having just one combustion zone, the double-annular combustor has a second combu.
Caution: Starter assist should be used if N2 is below 15 percent. Therefore, to obtain maximum engine service life, time at takeoff / high thrust should be held to the practical minimum, and rapid throttle movements avoided during normal flight operations. After testing the engine for several years, both in the air and on the ground, CFMI searched for customers outside of a possible AMST contract. science fiction, fantasy, thrillers, romance) and types (e. Data from CFM International General characteristics 1.
Although the CFM56 is a very reliable engine (CFMI state that there is only one in-flight shutdown every 333,333 hours),there have been several engine failures throughout the life of the CFM56 family which were serious enough to either ground the fleet or require aspects of the engine cfm56-7b manual to be redesigned.
