Do I recall correctly that the Merlin never achieved civilian certification?

No, you don't.
Avro York, Avro Tudor, Canadair North Star... I assume Haltons and Lancastrians were on the civil register too. |

Re civvy Merlins, from Wikipedia...
With the end of the war, work on improving Merlin power output was halted and the development effort was concentrated on civil derivatives of the Merlin.[22] Development of what became the "Transport Merlin" (TML)[23] commenced with the Merlin 102 (the first Merlin to complete the new civil type-test requirements) and was aimed at improving reliability and service overhaul periods for airline operators using airliner and transport aircraft such as the Avro Lancastrian, Avro York (Merlin 500-series), Avro Tudor II & IV (Merlin 621), Tudor IVB & V (Merlin 623), TCA Canadair North Star (Merlin 724) and BOAC Argonaut (Merlin 724-IC).[24] By 1951 the time between overhauls (TBO) was typically 650–800 hours depending on use.[25][26] By then single-stage engines had accumulated 2,615,000 engine hours in civil operation, and two-stage engines 1,169,000.[27] |
In the absence of news about the Sywell Tempest, an update on the P&W powered Canadian aircraft
|
|
What mind?
|
Hurricane is just a Spitfire; your go...
|
Is a Tempest with a P&W still a Tempest...?
|
A handicapped Tempest?
I still want to see it fly, no matter whether there's a P&W or a Bristol in there. |
