According to some napkin math (which looks positively terrifying when MinutePhysics writes it out on screen), the optimal size for a jet engine is somewhere around 13 feet in diameter, a little bit bigger than the biggest jet engines we have right now.
What is the largest jet engine?
The largest commercial jet engine offered to date is the General Electric GE9X engine. This has been designed for the new Boeing 777X. It is developed from the GE90 engine but has a larger fan and lighter construction. The GE9X holds the Guinness World Record for the highest recorded thrust, a huge 134,300 pounds.
How big is a 747 engine?
A Boeing 747 aircraft has a PW4000 engine with a 94 inch inlet diameter.
How small are jet engines?
Only 24 inches long, the TRS 18 is still the smallest jet engine ever to power a manned aircraft. Those early mini-engines had a problem, though.
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.
What engines do the 777 use?
The 777-300ER is powered by two General Electric GE90-115B jet engines, the world’s most powerful airline jet engine. It can produce up to 115,300 lbf (513 kN) of thrust. More than 25 years after its first flight, the engines for Boeing 777 still impress with game-changing efficiency, range, and thrust.
How big is a 777 jet engine?
of thrust, GE delivered the GE90-115B engine, which now powers the longer-range Boeing 777-200LR, 777-300ER and 777 Freighter aircraft.GE90-115B Engine. -94B -115B Physical Information Low-Pressure Turbine / High-Pressure Turbine 6/2 6/2 Maximum Diameter (Inches) 134 135 Length (Inches) 287 287.
Can a 747 take off with 2 engines?
Question: If two engines on the same wing of a 747-400 fail, can the jet fly on the other two? Answer: It depends on the weight and the altitude. At very heavy weights and high altitude, maintaining altitude on two engines may not be possible. At lighter weights, it may be possible to maintain altitude with 2 engines.
How many engines can a 747 fly on?
A 747–400 can safely LAND with as few as two engines, however, the integrity of flight will be compromised with only one engine down. To maintain height, a light 747 could run on 2 engines.. But Boeing designed the aircraft to atleast hold altitude on 3 engines fully loaded, and to procede take-off.
How much is a jumbo jet?
COST. Today, the newest model of the 747, the 747-8, is on sale from Boeing for $386.8 million US.
How much is a micro jet?
When it comes to high-performance aircraft, of course, inexpensive is a relative term. The Eclipse 500 very light jet, sometimes called a microjet, costs about $1.5 million but boasts the same performance as rivals that can cost two or three times as much to purchase and operate.
What is mini jet engine?
PBS AEROSPACE production division, is a manufacturer of aircraft turbojet engines. These engines use power generated by the continuous burning of a mixture of fuel and compressed air. These engines are useful especially for experimental aircraft, sport gliders and unmanned aerial vehicles.
How much are jet engines?
While costs vary, most jet engines have a price tag of around $10 million to $40 million each. And being that most commercial airplanes use multiple engines, the cost of production can be quite expensive.
How much does an engine for a 777 cost?
Each engine costs $24 million. For the price of one engine you could get this beautiful Swiss home and two engines would get you three 1957 Ferrari 250 Testa Rossas, the most expensive car ever sold at auction.
How fast does air come out of a jet engine?
A typical speed for air molecules exiting the engine is 1,300 mph (2,092 kph). The bypass air generated by the fan – This bypass air moves at a slower speed than the exhaust from the turbine, but the fan moves a lot of air.
How much does a 777 cost?
The Boeing 737-700, listed at an average price of just under 90 million U.S. dollars, is among the least expensive models, while the Boeing 777-9, priced at 442 million U.S. dollars, is among the most expensive ones on Boeing’s price list.
How much is a Boeing 787?
Exclusive of discounts, the fly away list price of a Boeing 787-8 is US$248.3 million, a significant financial impost for many airlines.
Whats bigger 747 or 777?

What plane has the biggest engines?
The GE9X is the powerplant for the forthcoming Boeing 777X, and holds the Guinness World Record for the highest recorded thrust. It’s a huge beast, with a massive diameter of 134 inches (340 cm), but it’s not the biggest. The biggest engine in the history of commercial aviation will be the Rolls-Royce UltraFan.
