ramjet

音標發(fā)音

Ramjet engines have traditionally used liquid fuel which is mixed with atmospheric air and burned to provide thrust for high-speed flight.
傳統(tǒng)的沖壓噴氣發(fā)動機使用液體燃料并與大氣中的空氣混合燃燒，以提供高速飛行的推力。
In order to study the fuel mass flow rate regulation characteristics of tube-in-hole for solid fuel ramjet, the flow field of turbulent combustion was numerically analyzed.
為了研究固體燃料沖壓發(fā)動機內部套管結構調節(jié)燃料流量的特性，對某模型發(fā)動機的湍流燃燒流場進行了數(shù)值分析。
A new supersonic combustion ramjet, or scramjet, engine gets put through its paces at a NASA research center in a ground-based test that simulated Mach 5 conditions in 2008.
在美國宇航局研究中心，一個新的超音速燃燒沖壓噴氣發(fā)動機（scramjet）通過了模擬2008年5月5日環(huán)境的地面測試。

X-43A, which is pilotless, four metres long, and has a nose made of solid tungsten, will be the first working aircraft to be powered by a scramjet—a supersonic-combustion ramjet.
ECONOMIST: Jet propulsion
Unlike the more familiar turbojet, which uses a turbine-powered fan to compress the incoming air before it is mixed with fuel, a ramjet compresses air by forcing it down an ever-narrowing funnel.
ECONOMIST: Jet propulsion

a type of jet engine in which fuel is burned in a duct using air compressed by the forward speed of the aircraft
an aircraft powered by such an engine
