high-bypass-ratio turbofan engine
1Bypass ratio — The term bypass ratio (BPR) relates to the design of turbofan engines, commonly used in aviation. It is defined as the ratio between the mass flow rate of air drawn in by the fan but bypassing the engine core to the mass flow rate passing through …
2high-bypass turbofan — A turbofan engine with a bypass ratio of 4:1 or higher (i.e., four or more times as much air flows across the fan as across the core engine) …
3Turbofan — [ CFM56 3 turbofan, lower half, side view.] A turbofan is a type of jet engine, similar to a turbojet. It essentially consists of a ducted fan with a smaller diameter turbojet engine mounted behind it that powers the fan. Part of the airstream… …
4Bypass duct — A bypass duct is an annular passage that allows some of a turbofan s airflow to bypass the engine core, or gas generator. If the turbofan is unmixed, the bypass duct will terminate at the bypass nozzle. In mixed turbofans, the bypass duct leads… …
5Engine Alliance GP7000 — The Engine Alliance GP7000 (known as the GP7200 for a brief time period) is a new turbofan jet engine that will incorporate advanced technologies of proven wide body products, originally from the world s No.1 and No.3 aero engine manufacturers,… …
6Engine indicating and crew alerting system — An example of information found on a EICAS Engine Indicating and Crew Alerting System (EICAS) is an integrated system used in modern aircraft to provide aircraft crew with aircraft engines and other systems instrumentation and crew annunciations …
7Mixer (engine) — Turbofan engines often feature an exhaust mixer, where the bypass (cold) air is mixed with the core (hot) exhaust gases, before exhausting to atmospheric pressure through a common (mixed flow) propelling nozzle. Benefits The mixer reduces the… …
8jet engine — an engine, as an aircraft engine, that produces forward motion by the rearward exhaust of a jet of fluid or heated air and gases. Also called jet, jet motor. [1940 45] * * * Any of a class of internal combustion engines that propel aircraft by… …
9Jet engine — For a general overview of aircraft engines, see Aircraft engine. A Pratt Whitney F100 turbofan engine for the …
10Airbreathing jet engine — An airbreathing jet engine (or ducted jet engine) is a jet engine propelled by a jet of hot exhaust gases formed from air that is drawn into the engine via an inlet duct. All practical airbreathing jet engines are internal combustion engines that …
