Turbine components redesigned by Evans (5)
I believe the answer is:
vanes
'turbine components' is the definition.
The definition and answer can be both man-made objects as well as being plural nouns.
Perhaps there's an association between them I don't understand?
'redesigned by evans' is the wordplay.
'evans' can be anagrammed to 'VANES'.
However, I am not sure how this is indicated.
Can you help me to learn more?
(Other definitions for vanes that I've seen before include "Blades of a propellor or windmill sails" , "They show wind direction" , "Blades of a windmill or propeller" , "Weathercocks" , "Blades of a windmill (5)" .)
