The Biggest & largest engine is actually a JET engine .Yes, you heard it right, its a jet engine named General Electrical’s 90-115B. DESIGN:
According to official sources, it is 18 feet long and 11.25 feet wide and weighs about 18,260 pounds (which is really a massive weight for an aircraft engine). Originally, it was built for the 777-Boeing, where this engine officially entered into working state. It was developed by GE aviation in association with aviation of France, Italy and Japan. Based on NASA’s Energy Efficient Engine of 1970s, the high compressor piston produces the ever-produced pressure ratio of 23:1 (a commercial record) and a turbine is used to drive it which is basically air-cooled type, like we see in lighter engines of automobiles. A subsidiary pressure compressor helps the core to get supercharged .The higher power models are slightly different in built from the previous versions. The GE held similar re-staging processes when they upgraded the engine to higher power. However that power-increased growth route proved to be more costly because almost all downstream components (for example: the turbines should be bigger in terms of flow capacity, and as result, GE searched (and of course found) the leading engine manufacturer. That was an highly advance, larger diameter-ed unit that was then, made of composite and newer materials and thereby became the first engine with a sweep rotary blade system. This jet engine was powerful enough to operate the 747-Boeing test-bed with its own power, an unique feature that was actually displayed in one the flight tests, made by the aviation company. OPERATIONAL HISTORY: The first GE-powered 777-Boeing was officially hand-over-ed to the Supreme British Aviation on 12, November 1995. Although the aircraft, along with, the 2 other Boeing(s) entered into the working state about 5 days later from the British Aviation. The engine worked flawlessly without any glitches or issues whether they be technical or mechanical until the initial service was interrupted due to some issues in the gear box which even led the airlines to withdraw the planes for service from the trans-Atlantic region in around 1997. RECORDSJn 2003, a 777-Boeing broke the world record of flying continuously for five and half hours(5 hrs& 30 min) with its 1 engine core shut down.The G. Book of world Records, states that the massive engine holds record of highest thrust (569kN) although rated at 513kN. According to some sources,
the world-record was actually accomplished as a part of continuous red lined high strained test. In order to accommodate the increased stress activity the aviation made a completely new steel alloy then the engineered the alloy to built the huge cores and several other parts to sustain the extreme tolerance levels. In 2005, November this engine entered the G. Book of world Records, a second time. This time a better built new variant completed the largest flight ever by a commercial airliner, although there were no booked passengers but only some pre-invited guests. The 777-200R flew 13,422 miles (about 21,601 kilometer) from Hong-Kong to London in about 22 hrs which was a long journey to cover over the Atlantic and Pacific and also over the continental United States.
