turbofan

核心释义

1. 1.

   涡扇发动机:一种涡轮喷气发动机,具有通常带涵道的风扇,驱动部分气流旁通涡轮喷气部分；在高涵道比类型中,大部分推力来自旁通部分而非涡轮喷气部分。

   A turbojet engine having a (usually ducted) fan that drives a stream of air that partly bypasses the turbojet portion; in high-bypass-ratio types, most of the thrust comes from the bypass portion rather than the turbojet portion, and this can be thought of in simplistic terms as that the turbojet portion drives the fan and the fan propels the aircraft.

2. 2.

   由风扇喷气发动机推动的飞机

   an airplane propelled by a fanjet engine

3. 3.

   装有涡扇发动机的飞机。

   An aircraft with such engines.

4. 4.

   一种喷气发动机,涡轮驱动的风扇提供额外空气给燃烧室并增加推力

   a jet engine in which a fan driven by a turbine provides extra air to the burner and gives extra thrust
