Metropolitan-Vickers F.2
aircraft engine model
The Metropolitan-Vickers F.2 is an early turbojet engine and the first British design to be based on an axial-flow compressor. It was an extremely advanced design for the era, using a nine-stage axial compressor, annular combustor, and a two-stage turbine.
It first powered a Gloster Meteor in November 1943, outperforming contemporary models from Power Jets. Despite this excellent start, it was considered unreliable and did not see use during the war. In the post-war era, newer engine designs provided much higher performance, and interest in the F.2 waned.
The potential of the engine and the investment did not go to waste, however; the design was passed from Metropolitan-Vickers (Metrovick) to Armstrong Siddeley when Metrovick left the gas turbine business. Armstrong Siddeley produced a larger version as the successful Sapphire.
Development
Alan Arnold Griffith published a seminal paper in 1926, An Aerodynamic Theory of Turbine Design, that for the first time clearly demonstrated that a gas turbine could be used as a practical, and even desirable, aircraft powerplant. The paper started by demonstrating that existing axial compressor designs were "flying stalled" due to their use of flat blades, and dramatic improvements could be made by using aerofoil designs instead. It went on to outline a complete compressor and turbine design, using the extra exhaust power to drive a second turbine that would power a propeller.
Begin with the source’s own compact description: “Metropolitan-Vickers F.2” is aircraft engine model. The dossier treats that line as a proposition to test through Metropolitan-Vickers, aircraft and engine, not as a finished interpretation.
Why this record matters
The phrase “aircraft engine model” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Dec 21, 2025. The linked authority identifier is Q3855741. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1943 and 1926.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
