All you need to know about The ‘World’s Largest Jet Engine’

Largest Jet Engine

Biggest Aircraft Engine In the World General Electric’s GE90-115B, with a diameter of 3.25 metres, generating 115,000 pounds of thrust, is currently the biggest in the world. These engines are fitted on Boeing 777-300s,

  • In 1995 , First Introduced in British Airways 777

In 1995, the GE90 engine debuted aboard a British Airways 777 airplane along with commercial aviation’s first-ever carbon-fiber composite fan blades. Early GE90 engine models boasted outputs between 74,000 and 94,000 lbs. of thrust, and today it remains the world’s largest turbofan engine.

GE has continued to improve upon the GE90 design with larger variants (-110B and -115B) built exclusively for Boeing’s largest 777 models (777-200LR and 777-300ER). The GE90 is now the best-selling engine for that aircraft family.

  • Composite fan blade, Measuring more than four feet long. 

With the GE90, GE introduced the composite fan blade—the first-ever in commercial aviation. Measuring more than four feet long and weighing less than 50 pounds, the GE90 fan blade is made from carbon fiber and a toughened epoxy matrix that delivers double the strength and one-third the weight of titanium.

The GE90 fan blade’s uniquely curved design makes it larger, lighter and more aerodynamic than traditional titanium blades for reduced engine weight and lower fuel burn. Plus, the aerodynamic design allows the GE90 fan blade to pull large amounts of air into the engine, making it quieter and more efficient while generating unrivaled thrust.

  • World record thrust

The GE9X is made with parts from lightweight and ultra heat-resistant materials known as ceramic matrix composites (CMCs) that can operate at temperatures up to 2,400 degrees Fahrenheit. This allows the firm's engineers to keep the heat higher inside the engine, without having to burn through fuel or emissions

During certification testing in 2002, the GE90-115B engine set a world-record 127,900 lbs. of thrust. The GE90-115B ran for approximately 60 hours at triple red-line conditions (maximum fan speed, core speed and exhaust gas temperature) to evaluate the engine at its operational limits and demonstrate its capability beyond the most extreme operating conditions.

Testing of the engine is seen as a critical step towards development of the 777X aircraft family, a new version of the 777 ‘mini-jumbo’ with up to 406 seats that is due to enter service in 2020.

What is a Boeing P-8 airplane used for?

Boeing asked GE to develop an engine strong enough to power its 777X jet, which has prompted other airlines, including Emirates, Lufthansa and Qatar Airways, to place an order.

India is set to build a central command for the Air Traffic Control system, called ISHAN

India is set to build a central command for the Air Traffic Control system, called ISHAN
Coutresy : Boeing planes

India’s air traffic growth has led to increased responsibilities for air traffic control. The Airports Authority of India (AAI) is considering centralizing air traffic control for aircraft, dividing the country into four regions. The goal is to consolidate India’s segmented airspace into a single entity to improve air traffic management (ATM) efficiency, safety, and smoothness.

Recently, the AAI invited expressions of interest to develop a detailed project report for the Indian Single Sky Harmonized Air Traffic Management (ISHAN) initiative in Nagpur. Under this plan, air traffic controllers in Nagpur would handle domestic flights flying above 25,000 feet, eliminating the need for coordination among controllers in different regions.

For domestic regional flights operating above 25,000 feet, control would shift to the central command in Nagpur. This consolidation aims to enhance airline operations, increase flight handling capacity, and reduce congestion and flight times for passengers.

Currently, the AAI provides ATM services over Indian airspace and adjoining oceanic areas, covering over 2.8 million square nautical miles. This airspace is divided into four flight information regions (FIRs) in Delhi, Mumbai, Kolkata, and Chennai, along with a sub-FIR in Guwahati.

FIRs are responsible for providing air traffic services, including weather information, visibility, and search and rescue assistance. The proposed unification under the ISHAN initiative aligns with the projected growth of the aviation industry, which anticipates a doubling of domestic passenger traffic by 2030.

Airbus is set to increase the production rate for the A350 as demand surges

Airbus is set to increase the production rate for the A350 as demand surges

Airbus SE is set to boost production of its advanced A350 widebody jet as it capitalizes on rising demand for long-distance travel and wide-body aircraft, amidst the ongoing crisis affecting its competitor Boeing due to issues with the B737 Max.

The surge in orders for Airbus’s A350 aircraft has instilled confidence in the company, prompting them to ramp up production rates. This move is particularly advantageous as Boeing continues to grapple with production quality issues surrounding its 787 and 777x aircraft.

In 2024 alone, Airbus has received 137 orders for the A350, signaling a need to expand manufacturing capabilities to meet customer demands. With 1,277 orders received and 592 aircraft delivered as of April 2024, Airbus is poised to fulfill pending deliveries efficiently.

The European aircraft manufacturer announced plans to increase production of A350 jets to 12 per month by 2028, surpassing earlier projections aiming for 10 per month by 2026. This decision was disclosed alongside the company’s first-quarter figures.

The Asian market is proving lucrative for the A350, with significant orders from airlines like Indigo and Air India, totaling nearly 70 aircraft commitments for the future. Meanwhile, Airbus is progressing with its A220 and A320 programs, aiming for a monthly production rate of 14 and 75 aircraft, respectively, by 2026. Additionally, the long-range A321XLR is anticipated to commence service in the third quarter of the current year.

In contrast, Boeing has been compelled to scale back production due to regulatory pressures aimed at enhancing factory processes. While Airbus anticipates a positive market outlook, Boeing continues to face challenges with FAA certification and quality approvals, resulting in ongoing delays for its 737 Max and 777x models.

All passengers killed in plane crash, after pilot let his children to control the plane

All passengers killed in plane crash, after pilot let his children to control the plane

When boarding a plane, passengers entrust their safety to the skilled hands of the pilot. However, tragedy struck when one of the flight ended in disaster as all passengers lost their lives in a horrific plane crash.

In 1994, during a flight from Moscow to Hong Kong, tragedy struck as an Aeroflot relief pilot made a fateful decision. In a move that would have devastating consequences, the pilot invited his own children into the cockpit to play with the controls. Little did anyone know, this seemingly innocent gesture would lead to the loss of all 75 lives aboard the aircraft.

It was a seemingly innocent act that led to catastrophic results. The relief pilot, Mr. Kudrinsky, invited his two children, Yana, 12, and Eldar, 15, into the cockpit during the late hours of the night. Little did anyone know, this simple gesture would set off a chain of events that would end in tragedy.

Once in the cockpit, the children were allowed to sit in the captain’s chair and play with the controls, unaware that they should have been disabled as the plane was in autopilot mode.

Eldar, perhaps in a moment of curiosity or innocence, held the control column down for a mere 30 seconds. Yet, in those brief moments, the autopilot disengaged, thrusting the aircraft into manual control.

By the time the pilots regained their seats and attempted to regain control, it was too late. Despite their efforts to pull the plane out of a dive, they overcorrected, causing the flight to climb almost vertically, ultimately stalling it.

Final moment Flight 593 crash

In the final moments, as the pilots struggled to stabilize the aircraft, Flight 593 crashed into the Kuznetsk Alatau Mountain range in southern Russia, completely obliterating the plane and claiming the lives of everyone on board.

Investigations revealed a chilling truth: there was no evidence of technical failure. Instead, the crash was attributed to the unthinkable decision to allow inexperienced hands to manipulate the controls of a commercial aircraft.
