Types of civil airliner engines

There are mainly the following types: Turbofan: This is the most common engine type in civil airliner aircraft. The main difference between turbofan engines and turbojet engines is their combustion chamber structure. The advantages of this engine are high thrust, low fuel consumption and low noise, so it is widely used in modern civil airliners.

Nowadays, civil airliners generally use turbofan engines. In terms of its working principle, the turbofan engine belongs to a kind of turbine (the rotation of the fluid impact impeller generates power); at the same time, in terms of its working principle, the turbofan engine belongs to a kind of jet engine (ejecting high-speed fluid work).

Aviation engines are mainly divided into two categories: turbofan engines and turbojet engines. Turbofan engines are the most common and widely used type of engines in modern aviation.

There are 3 types: 1 piston aircraft engine. The aviation engine used in airplanes or helicopters in the early days was used to drive propellers or rotors. The power of large piston aircraft engines can reach 2,500 kilowatts. Later, it was replaced by a gas turbine engine with high power and good high-speed performance.

Aviation engines are mainly divided into the following two categories: Jet engines: Jet engines are engines that use the combustion of fuel to produce high-temperature and high-pressure gas, which are sprayed through the nozzle to form a high-speed gas flow and generate thrust to drive the aircraft forward. Jet engines are usually divided into turbojet engines and centrifugal jet engines.

The turbofan engine is a kind of turbine in terms of its working principle. At the same time, in terms of its working principle, the turbofan engine is a kind of jet engine. Therefore, the current passenger aircraft generally use turbofan engines.

Is the passenger plane a turbojet engine or a turbofan?

1. The two concepts of "turbine" and "jet engine" do not conflict. To be precise, the current passenger planes use "turbine fan blade jet engine". The turbofan blade engine (vortex fan engine) is improved from the turbine jet engine (vortex injection engine).

2. Nowadays, most civil aviation aircraft use turbofan engines. The turbofan engine is started by turbojet.Compared with the turbojet engine, the turbofan engine has lower fuel consumption and higher efficiency. It flies longer and is more economical with the same fuel. Therefore, the turbofan engine has basically been replaced by the turbofan.

3. The types of civil airliner engines include piston propeller engine, turbojet engine, jet turbine fan engine, turboprop engine and turbofan engine. Piston propeller engine: that is, the engine of an old-fashioned aircraft before World War II, relying on the piston to drive the propeller to rotate through the crankshaft, but it cannot reach supersonic speed.

4. Fighters are also turbofan engines [constant attack angle turbine fan engine], and passenger aircraft are also turbofan engines [self-attack angle channel fan engine]. They are all turbofans. Fighters rarely use turbojets, and the efficiency is too low.

5. Generally speaking, aircraft such as 737 can be regarded as jet aircraft, but in terms of aviation majors, the optional CFM-56 engine or IAE V2500 engine of the 737 is a turbine fan engine and cannot be regarded as a jet engine. The only real jet engine is a turbojet engine.

What engine does c919 use?

The engine of C919 is a LEAP-X1C engine. It adopts many industry-leading innovative technologies. The LEAP-X1C engine is a large jet passenger engine developed by CFM International, a large passenger engine manufacturer jointly established by the international company General Electric of the United States and SNECMA of France at a rate of 50% of the capital.

c919 aircraft engine is not domestic, but uses the first CFMLEAP-1C engine of CFM International Company. According to the structural decomposition diagram of the C919 aircraft, AVIC Industrial Group undertakes the main manufacturing task of large parts of the C919 aircraft.

c919 engine is not domestic, but uses the first CFMLEAP-1C engine of CFM International Company. The following is a relevant introduction to the c919 engine: C stands for China (China); 9 stands for long-term; 19 stands for the maximum passenger capacity of 190 seats.

Excuse me, what kind of engine is used in the passenger plane? Is it a turbojet or a turbine?Or?

Turbine engine This is the most commonly used engine in modern civil aircraft. There are several types of turbo engine: turbine shaft engine, turboprop engine, turbojet engine, etc.

Nowadays, civil airliners generally use turbofan engines. In terms of its working principle, the turbofan engine belongs to a kind of turbine (the rotation of the fluid impact impeller generates power); at the same time, in terms of its working principle, the turbofan engine belongs to a kind of jet engine (ejecting high-speed fluid work).

Jet turbofan engine: It belongs to a kind of jet engine, developed from turbojet engine, which is more fuel-efficient than turbojet engine. Nowadays, most military and civilian aircraft are in use. It is the most common engine of civil airliners.

Most of the gas energy from the tail spray is consumed on the turbine, and the thrust provided is only about 20% to 30%.

How many engines does the plane have?

1. Common aircraft are usually equipped with two engines, which are called twin-engine aircraft. However, there are also single-flight, three-flight, four-flight and six-flight aircraft.The number of engines mainly depends on the size, shape and thrust required of the aircraft. The engines of twin-engine aircraft are generally located below the wings near the root of the wings.

2. In general, there are the following situations: Most fighter jets have only **one** engine, but there are also a few fighters equipped with two engines, such as the American F-14 "Male Cat" and F-18 "Bumblebee".

3. Small and medium-sized civil passenger aircraft are generally equipped with two or three engines. Large passenger aircraft can be divided into twin-engine passenger aircraft and four-engine passenger aircraft depending on the model. Take the Boeing 787 as an example, the Boeing 787 is a double-engine large passenger aircraft. The typical three-tier seat design in its variant model can accommodate 242 to 335 passengers. It is a dual-engine wide-body medium and long-range passenger aircraft.

4. Small and medium-sized civil airliners are generally equipped with two or three engines, and large civil airliners generally have four to five engines, such as A380 and Boeing 747. Fighters are jet engines, and there are single and double engines. Generally, medium and short-distance passenger aircraft, such as 73320 It's 2.

5. Fighters are generally equipped with engines in terms of light and heavy duty. The light ones are mostly single-engine, and the heavy ones are double-engine. Most transport aircraft (including civil aircraft) use dual-engine and four-release stations. In fact, the size of the aircraft also determines how many engines. There are also three-strens of Soviet transport aircraft.
