Post-winter servicing test run of a Rolls-Royce Merlin - with flames

Описание: Winter maintenance is now complete, and the engine was tested over a series of test runs (see previous years videos to show what is covered).

This was a special short run for the camera, our first HAE event is on March 5th, 2026 to mark the 90th anniversary of the first Spitfire test flight. A suitable spitting fire engine start :-)

It is not something I do if I can avoid it. Flamey starts can be a sign of poor priming judgement. This was done on purpose.

This Merlin is a single stage, two-speed supercharged, T24-2 spec engine rated at 1,620hp at +18psi supercharger boost pressure. The propeller is a fully functioning Hamilton Standard 23EX, with constant speed and feathering functions, and has been cropped to 8 feet diameter from its original 13 feet. Maximum display power is typically 2,300rpm at -2psi boost (approximately 500hp).

Original manufactured as a Merlin Mk22 in June 1943 at the Rolls-Royce Derby factory in England, probably for an Avro Lancaster Mk1. Upgraded in 1945 to a T24-2 engine for an Avro York used by RAF Transport Command. In the early 1950s the engine was renumbered and sold in a batch of 400 Merlins to CASA in Spain for use on the CASA 2.111 bomber. Obsolete by the mid 1970s and returned to the UK for use in a research wind tunnel until being acquired as a core engine by David in 2007.

The Historic Aero Engine is a Facebook group of aero engine enthusiasts from a variety of engineering and technical backgrounds, who share a common interest in researching, restoring, and preserving our aero engine heritage. Some of the engines are restored to ground running condition, and when invited, can display these at public events as a means of celebrating our heritage and inspiring the next generation of young engineers.
