Aircraft Engines

General Electric GE90

Thrust-to-weight ratio: 5.59

The engine blades are made of composite materials so that it can work in much higher temperature. It is used in one of the biggest aircraft, Boeing 777 and has a world record thrust rating between 330 to 513 KN (high thrust variants). It powered three 777 variants-200LR, -300ER and -200F.


Rolls Royce Trent 900

Thrust-to-weight ratio: 5.46/ 6.11

The Trent 900 is a series of turbofan engines and one of the family members of Trent engines. It was first used in 2004 and has four variants which are used in different airliners. It is equipped with 116 inch wide low pressure compressor fan and the total weight is over 6200 kg. It has one of the most powerful engines with the maximum thrust value of 374 KN. It is the first engine in his family which fitted with the advanced engine health monitoring system.


General Electric GEnx

Thrust-to-weight ratio: 5.15/ 5.56

The General Electric GEnx (next generation) is a high-performance bypass turbofan jet engine, which is largely derived from General Electric’s GE90 engine. It employs many features of GE90 including the radical composite fan technology.

 

The engine was first commercially used in 2008 and it’s currently used as a frontline engine in Boeing 747-8 and 787 Dreamliner. It has the maximum thrust of up to 330 KN and a dry weight of 5800 kg. It also features fuel burn reduction technology, which also helps reduce engine noise


GE TF39

Thrust-to-weight ratio: 5.4:1

The US-based multinational company General Electric manufactured the TF39 especially to fulfill the need of Lockheed produced C-5 galaxy, one of the largest and heaviest military transport aircraft in the world. Although the engine is now disbanded, it was the first ever high-bypass turbofan jet engine produced. It was also the first turbofan engine in the 1960s that introduced revolutionary 1½ stage fan blades with an 8:1

Pratt & Whitney PW4000

Thrust-to-weight ratio: 6-7

The Pratt & Whitney PW4000-112 is the newest member of PW4000 family, which have higher thrust rage than any of the previous variants. Pratt & Whitney started manufacturing the PW4000 for the first time in 1984. It is used by many airliners including Airbus (A300, A310, A330), Boeing (747-400, 767, 777, KC-46) and McDonnell Douglas MD-11. The PW4000-112 entered into the commercial aviation industry in 1995 as one of the three options for Boeing 777 variants.

Engine Alliance GP7000

Thrust-to-weight ratio: 5.197

The Engine Alliance GP7000 is a turbofan jet engine which currently powers the world’s largest passenger airliner, the Airbus A380. It was first launched in April 2004 and the result of a collaboration between General Electric and Pratt & Whitney, two of the three biggest aircraft engine manufacturers in the world. It should have been called Super Engine Alliance, imo.


Rolls Royce Trent 700

Thrust-to-weight ratio: 51.35 N/kg

The Rolls Royce Trent 700 is a robust turbofan engine which is mainly used in the modern Airbus A330. During the late 1980s, when the new A330’s was launched with increased weight, Rolls Royce planned to design a new, more powerful and heavier engine to comply with it, which they later named Trent 700.

 

It first entered into service in March 1995 with Cathay Pacific with a maximum thrust rating up to 316 KN. Back in 2009, the company launched an upgraded version of the Trent 700, the Trent 700EP (enhanced performance) with some necessary improvements.

 


CFM56-7 Series

Thrust-to-weight ratio: 3.7:1

The CFM56-7 is the latest edition of CFM56 series engines, manufactured by CFM International, which debuted in 1995. With a maximum takeoff thrust (newer model) of 27,300 ibf, it’s the perfect engine to power the next generation Boeing 737 with better fuel efficiency and reduced maintenance costs. Other major applications of this engine are in Boeing KC-135 Stratotanker and Airbus A320 family.

Rolls Royce Trent XWB

Thrust-to-weight ratio: 5.25

The Rolls Royce Trent XWB is a family of turbofan jet engines which is used for the Airbus A350 XWB. It was first successfully tested in 2010 and developed as a competitor to the Boeing 787 Dreamliner. It has five variants and the largest fan diameter is 118 inches. The advanced version has the maximum thrust of 430 KN. Rolls Royce uses these engines in the Qatar Airways and Airbus A350-1000.

Rolls Royce Trent 1000

Thrust-to-weight ratio: 6.1

Evolved from the previous generations of the Trent engines, the Rolls Royce Trent 1000 was conceived to fulfill the needs of Boeing 787 Dreamliner. Back in 2004, Boeing decided to provide its customers with an option of choosing between the two engines in their new Dreamliner series. As a result, General Electric GEnx and Trent 1000 were finalized.

 

Trent 1000 powered the first Boeing 787 on its maiden test flight and also during its first commercial flight. The engine has a dry weight of more than 6,000 kilograms with a maximum thrust of 265.3–360.4 kN.


General Electric CF-6

Thrust-to-weight ratio: 5.08

The General Electric CF-6 is one of the most powerful series of high bypass turbofan engines produced by General Electric aviation. Currently, it is being used in many commercial airliners, including Airbus (A300, A310, A330), Boeing (747, 767) and McDonnell Douglas. The engine is equipped with two high pressure and four low-pressure turbines with the maximum thrust value of 274 KN. Moreover, it’s 4.65 meters in length and weighs more than 4100 kg.
