On p86 he says 'It followed the idea of multi-vane auxiliary air inlets into history."
Anyone know the story on these inlets?
They were an attempt to avoid the mechanical complexities of the prototype double hinged 'barn door' combined dump door/auxiliary intake by having several 'blow-in' vanes set in the door which were locked when the door was operated as a dump door.
Had their own set of mechanical problems and the idea was abandoned in favour of a single blow-in door (production solution)
