What planes have CFM engines?

Designed, developed and produced by CFM International, the CFM56 engine powers single-aisle commercial jetliners from Airbus (A320 family) and Boeing (737 family), as well as various military aircraft.

### How many horsepower is CFM56?

The CFM International CFM56 (U.S. 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).

How much CFM do I need for my car?

As a general rule of thumb, follow these minimum cubic feet per minute (cfm) ratings when using an electric fan as the primary cooling source on a basic engine: 1,250 cfm for a 4-cylinder. 2,000 cfm for a 6-cylinder. 2,500 cfm for a 8-cylinder.

How do I choose CFM for carburetor?

The formula for calculating how much CFM (cubic feet per minute) your engine requires is: CFM = Cubic Inches x RPM x Volumetric Efficiency ÷ 3456. Any ordinary stock engine will have a volumetric efficiency of about 80%.

How much airflow does an engine need?

When we don’t have the airflow numbers, we can use the general rule of 2.5 times the horsepower of the engine to get an approximate amount of air required.

### What is the right size carburetor?

To arrive at the most appropriate carburetor choice, there’s a basic formula: engine displacement multiplied by maximum rpm divided by 3,456. For example: a typical 355ci small-block—a 0.030-over rebuild—with a 6,000-rpm max engine speed would work well with a 616-cfm carb ((355 x 6,000) 3,456 = 616.32).

Why is there a spiral in a jet engine?

The primary function of the spiral is to warn the ground crew working around the aircraft that the engine is on and to ensure nobody comes up too close to the running engine.

What is the most efficient jet engine?

GE Aviation’s latest engine is the GE9X, which the company says is the most fuel-efficient engine it has ever produced. Developed for the Boeing 777X, the GE9X is ten percent more fuel efficient than the GE90 and produces fewer NOx emissions than any other GE engine.
