And then there are so many different types of engines, which each have their own thrust rating. Roughly speaking, an engine can cost anything from 12 to 35 million dollars.
How much does a 737 engine cost?
Aircraft Pricing
| Aircraft model | Engine | New Price |
|---|---|---|
| Boeing 737-800 | Pratt & Whitney, GE, ROLLS-ROYCE | $89.1M |
| Boeing 737-900ER | Pratt & Whitney, GE | $94.6M |
| Boeing 747-400 | Pratt & Whitney, GE, ROLLS-ROYCE | $240M |

How much is a 747 engine cost?
The 747-400 model has three engine options available: PW 4056, GE CF6, and RR RB211. These engines are also used on other aircraft, which will help in finding the prices. The CF6 engine has a list price of about $11 million (from an A330 order in 2009, higher thrust version; $12.2 million in 2015 USD1).
How long do jet engines last?
The high performing engines typically are specified to last 3000+ hours and the long lasting engines are often specified to last 30000 hours and usually last longer. The 30000 hour number is 3 1/2 years of continuous 24/7 operation.
What makes jet engines so expensive?
Jet engines are so expensive, because they are getting more and more sophisticated and fuel efficient. After landing the A380, the controls to shutdown the engine were not working. Firefighters tried for hours to shutdown the number 1 engine without success.
How much does a Rolls Royce jet engine cost?
Cost. In 2000 Qantas were quoted a price of US$12.85 million per Trent 900. In 2015 Emirates Airlines signed a contract for 200 Trent 900s including long-term service support at a cost of US$9.2 billion or US$46 million per engine.
Why are 777 engines so big?
The reason why: the new engines offer far greater fuel efficiency and much less noise thanks to composite 3D printed materials and larger fan blades. By reducing weight with previously unattainable materials, the engines are able to draw more air, which greatly improves the efficiency and noise part.
Why can’t China make jet engines?
Material sciences in China have not yet advanced to the point where they can make turbines as good as what is available in the Western world. The reason why jet engines are so fuel efficient is because of the inlet temperatures of modern engines. They have to withstand very high temperatures.
How many 747s have crashed?
Of the 61 Boeing 747 aircraft losses, 32 resulted in no loss of life; in one, a hostage was murdered; and in one, a terrorist died. Some of the aircraft that were declared damaged beyond economical repair were older 747s that sustained relatively minor damage.
Why 747 has a hump?
Hence the engineers went for a second deck that housed the cockpit in the Boeing 747-100. Because of aerodynamics, the cockpit level had to rise and slope back down to the main fuselage, giving us the iconic hump.
Does heavy rain affect jet engines?
Although rain is capable of hindering the function of a jet engine, it is rarely a noticeable effect. The majority of storms do not create enough rain or snow to disturb the engines, and the ice crystals that clouds are made of are far too small to affect function.
Are jet engines reliable?
The main reason jet engines are so reliable is that they have far fewer moving parts that rub against other things than any other type of engine. Sliding friction involving main crank bearings, connecting rod bearings, and at the cylinder wall/piston ring interface present is absent in jet engines.
Do Jet Engines need oil?
Do Jet Engines Require Oil Changes Like Car Engines Do? Generally, there are no scheduled oil changes for jet engines. … Typical “top‑ups” are done on a daily basis, so jet engines always have some fresh oil but rarely need a complete oil change.
What is the cheapest jet engine you can buy?
The cheapest private jet on the market is the small but mighty Cirrus Vision Jet at $1.96 million. The Vision Jet is the world’s first single-engine private jet, powered by a Williams International FJ33-5A turbofan engine that produces 1,800lbs of thrust.
How long does it take to build a jet engine?
Building and assembling the components of a jet engine takes about two years, after a design and testing period that can take up to five years for each model. The research and development phase is so protracted because the engines are so complex: a standard Boeing 747 engine, for example, contains almost 25,000 parts.
What is the simplest type of jet engine?
Most modern passenger and military aircraft are powered by gas turbine engines, which are also called jet engines. The first and simplest type of gas turbine is the turbojet.
