How this entity was disambiguated

This entity first appeared as the object of triple T1109944 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07

Target entity: Rolls-Royce Conway engine
Context triple: [Rolls-Royce Limited, notableProduct, Rolls-Royce Conway engine]

A. Rolls-Royce Nene engine
The Rolls-Royce Nene engine is a pioneering late-1940s British centrifugal-flow turbojet whose powerful, compact design significantly advanced early jet aircraft performance and was widely exported and copied worldwide.
B. Rolls-Royce Avon engine
The Rolls-Royce Avon engine is a pioneering British axial-flow turbojet developed in the late 1940s that powered numerous military and civilian aircraft, including early jet airliners and fighters.
C. Rolls-Royce Griffon
The Rolls-Royce Griffon is a powerful British liquid-cooled V12 aero engine developed during World War II, best known for powering later, high-performance variants of the Supermarine Spitfire and other Royal Air Force aircraft.
D. Rolls-Royce Pegasus turbofan
The Rolls-Royce Pegasus turbofan is a unique vectored-thrust jet engine that enables vertical and short takeoff and landing (V/STOL) capability in aircraft such as the Harrier family.
E. Rolls-Royce Adour turbofan
The Rolls-Royce Adour is a family of low-bypass turbofan engines developed for military trainer and light attack aircraft, noted for their reliability and widespread use in jets such as the SEPECAT Jaguar and BAE Systems Hawk.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
