The beast of a creation that is the Sabre VII H24 sleeve valved engine. Napier’s design was not without its teething trouble. #warbirds #ww2 #ww2history #napier #sabre | Daniel J Wheatcroft

Sabre rattling - Napier Sabre H24 and Hawker Tempest V #ww2 #ww2history #napier #sabre #TEMPEST | Daniel J Wheatcroft

Napier Sabre H24 - the engine that succeeded where the Rolls-Royce Vulture X24 did not. The output of Carbon Monoxide from the Sabre’s 24 cylinders was considerable, and the design of the Typhoon eventually necessitated that aircrew use oxygen at all times, even during ground ops. Sadly lives were lost before the CO issue was fully understood, but the Sabre was nonetheless a vital engine in UK aircraft development.
