It notes that the clouds of volcanic ash can ablates jet engine blades and vanes as the so-called ash is composed of bits of pulverized rock ranging from millimeter size down to micrometer range. It states the consideration to conduct a research and development that will look for ways to ...

So I am sure that jet vanes are used for steering rockets and I was just wondering if the technology for making such composite material is related to the technology of making turbine blades? If there is any similarity in between, would the technical know-how as to make one imply the abili...

Older engines had stationary vanes in front of the moving blades. These vanes also helped to direct the air onto the blades. The air flowing into a turbojet engine is always subsonic, regardless of the speed of the aircraft itself. 【参考译文】在压缩机前面需要一个进气口或管道,以帮助将进入...

The turbofan has two counter-rotating fans (3, 5), and a low pressure compressor (7). The compressor has a downstream crown (18) of rotating blades (19) connecting the fan (5) to a drive shaft (6) of the fan (5). An upstream crown (40) of rotating blades (41) is connected to...

As the aircraft accelerates through Mach 3, the turbojet is shut down and the intake air is diverted from the compressor, by guide vanes, and ducted straight into the afterburning jet pipe, which becomes a ramjet combustion chamber. This engine is suitable for an aircraft requiring high speed...
摘要：This jet engine (1) is provided with: a fan (3, 31, 32, 33) having moving blades (3b1, 3d1, 3g1, 3i1, 3k1) in a plurality of stages; compressors (4, 5) which compress air fed from the fan (3, 31, 32, 33); a combustor (6) which generates combustion gas using ...
