takeoff thrust

takeoff thrust

The jet thrust approved for normal takeoff and limited in the period of time for which it can be used. This period is normally 2½ min. This may not always be the case.

The aircraft with higher bypass ratio engine needs more engine takeoff thrust to meet the takeoff filed length and engine-out climb gradient requirements, which leads to increment in the aircraft weight and a higher DOC.
Through technology enhancements that provide greater performance, efficiency and lower environmental impact, the PW307D delivers increased takeoff thrust and improved fuel consumption compared to the PW307A engine.
In addition to fuel savings, the airline sees benefits from reduced engine takeoff thrust, reduced emissions, greater payload and range capability, and greater operational flexibility.
The PW4000 Series is a family of large-scale commercial aircraft engines with a takeoff thrust ranging from 52,000 to 98,000 pounds (lbs).
I then called for takeoff thrust, and away we went.
The engine was designed to deliver 115,000 lb of takeoff thrust to power Boeing's longer-range 777-330ER and--200LR aircraft.
In 1995, UT's aerospace and aviation research efforts paid off in the delivery of the Boeing 777, which uses P&W's 4084 jet engine - at 84,600 pounds of takeoff thrust, the most powerful ever in commercial aviation.
The two engines produce 172,000 pounds of takeoff thrust, equivalent to what the four engines of a 747 produced when it began service in 1970.
GE90 will be rated from 75,000 to 95,000 pounds takeoff thrust. It is scheduled for certification at 87,400 pounds thrust in 1994 and entry into service at between 70,000 and 75,000 pounds on the new Boeing 777 in mid-1995.
Finally, the optimized value of the engine takeoff thrust has also resulted in reduced fuel consumption.
