Yankee Blackhawk in the Afghan
Our esteemed General Sir Richard Dannatt was thankfully flown around the various places he needed to be courtesy of our American Brothers in Arms, whilst the big bird was landing just to rear of the front engine air intake there seemed to be a springloaded flap that was flipping (not like an English MP) open and closed it seemed to be about 6" x 6", would this be taking in additional air or dumping it, for when under full power I cannot recall seeing this flap opening, can anyone explain this?

My guess is that it is taking in additional air.
The shroud on the inlet has a springloaded flap that can swing inwards. Not sure why it is only present on the bottom though as there are 2 ducts under the shroud.

That panel the door is on is part of the Hover Infra-Red Supression System (HIRSS) kit. It is a shroud that covers up two engine bay air intakes on the engine inlet that were put on to keep the engine bay ventilated and cool, but provided a clear visible shot to the hot engine for an IR guided missile to seek on. At a hover, the flap opens (and closes) to allow the vents to do their purpose (a bit), and during forward flight it springs closed and provides the absolute minimum direct view of the hot engine.
It's also a handy way to check the engine oil!
