Sep 2, 2015 · Many airline engine nacelles have small fins (strakes or chines). During takeoff and landing, the engine blocks some of the air flowing over the wing causing a decrease in lift. To counteract...

GE Aircraft Engine's GE90-115B engine powers the 777-300ER. Each engine produces 115,000 pounds of thrust -- nearly a quarter of a million pounds of total thrust for the airplane. By comparison, the original 777 had 75,000 pounds of thrust per engine.

Dec 3, 2023 · An aircraft engine nacelle is the engine covering that encapsulates and protects the engine and other components of the engine, including thrust reverser, fire and anti-ice systems, and the engine exhaust.

Nov 18, 2021 · Boeing has expanded its proposed nacelle changes for Pratt & Whitney-powered 777s to include thrust reverser modifications, the company told the FAA in a regulatory filing.

Apr 26, 2006 · In fact the engine nacelle is, I believe, the same on GE90- 76, 94, and 115B. It is in fact the fan that is slightly larger. Because of the composite blades used in the 115b they are able to use a closer fit in the nacelle.

The 777 is the widest, most spacious airplane in its class and includes improvements in airfoil technology, flight deck design, passenger comfort and interior flexibility. Its greater payload and range capability result in lower operating costs to airlines, and its standard equipment includes many features that are optional on other airliners.

The Model 777 was the first jetliner to be 100 percent digitally designed using three-dimensional computer graphics. Throughout the design process, the airplane was preassembled on the computer, eliminating the need for a costly, full-scale mock-up.

Jul 24, 2016 · Vortex generated by the nacelle strakes on a Boeing 777-300 ER engine during takeoff from New York. This vortex helps in maintaining lift under high angle of attack and low speed scenarios faced...

Figure 19 Nacelle Inlet External Flow Environment For the 777, the nacelle was designed to satisfy stringent engine-inoperative criteria for takeoff and ETOPS conditions. The criteria used were to minimize engine-inoperative spillage drag at second-segment climb conditions to provide maximum performance

Jan 4, 2019 · That engine has exclusively powered Boeing’s 777-300ER since it entered service with British Airways in November 1995. With a maximum engine pod diameter of 166 inches, the GE-90 was...
