Talk:Spiral slipstream

From Wikipedia, the free encyclopedia

[edit] Spiral slipstream

I assume this is a technical term used 'across the pond' as being UK-based I have never heard the term used here.

AFAIK, the UK term for the airflow produced by a rotating propeller is (or was) just 'Slipstream', the term originally referring to the airflow produced by the rotating propeller when the aircraft is stationary on the ground and the airscrew 'slips' rather than pulling the aircraft through the air. It's more often heard (possibly technically incorrectly) referring to the 'wind' that one feels when in flight when poking your head out of an opened cockpit.

A quick check of A. C. Kermode's The Mechanics of Flight:

The Slipstream

The propeller produces thrust by forcing air backwards, and the resultant stream of air which flows over the fuselage, tail units, and other parts of the aeroplane is called the slipstream.

I'll add in the opening line that in the UK the term is just 'slipstream'. Ian Dunster 16:46, 27 March 2007 (UTC)
