DH.91 Albatross

In 1940, A.C. Kermode was evidently struck with the streamlined efficiency of the Albatross design, as was D.P. Davies with that of the Boeing 707 two decades later. Interesting that its total power was not much different from the DC-3**.

What a super photo (as always), evansb. Interesting cowlings for the inverted V12, air-cooled Gypsy 12s.





Ahhh, de Havilland... Perhaps we need an Albatross thread.

** [EDIT] There seems to be some confusion on the sea-level T/O power of the DH Gypsy 12: was it 425 HP or 525 HP? Another comparison with the 1100 HP Wright Cyclones or the 1200 HP Twin Wasps of the DC-3 might relate to the effectiveness of their respective superchargers at cruise altitude. I now see that, as well as having a longer fuselage and wingspan, the MTOW of the Albatross was higher than that of a DC-3 or civil-registered C-47. It was a lot faster, but the quoted range (always a bit nebulous unless a payload is quoted) seems a bit limited for trans-Atlantic ops.
