The Napier Sabre represented the ultimate in piston engine technology, not only in the 1930s when it was conceived, but even by today īs standards. It was a truly remarkable engine, representing the ultimate in complexity, technology, specific power, and unfortunately .... problems. In retrospect it can be stated that many of the Sabre's woes were due the pressures in wartime England to get the latest technology into production as rapidly as possible, even though many of the "bugs", both design - and manufacturing-related, had not been work out. |
