Bypass 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 … Wikipedia
high-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) … Aviation dictionary
high-bypass — An engine with a bypass ratio in the region of 15:1. These engines may be used for reverse thrust. This type of configuration is known as a cold reverse thrust as opposed to a hot reverse thrust, which is provided by hot exhaust gases … Aviation dictionary
very high bypass — An engine with a bypass ratio in the region of 15:1. These engines may be used for reverse thrust. This type of configuration is known as cold reverse thrust, as opposed to hot reverse thrust, which is provided by hot exhaust gases … Aviation dictionary
Bypass 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… … Wikipedia
Engine 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,… … Wikipedia
Engine 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 … Wikipedia
Airbreathing 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 … Wikipedia
Variable Cycle Engine — In a Variable Cycle Engine (VCE) the engine cycle is deliberately modified from that which would occur under normal circumstances.The next generation of Supersonic transport (SST) may require some form of VCE. SST engines require a high Specific… … Wikipedia
Mixer (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… … Wikipedia
ultrahigh bypass — A bypass engine with a very high bypass ratio. Such engines are expected to have very low noise emission levels … Aviation dictionary
