Target class: marine gas turbine engine Context triple: [Rolls-Royce WR-21, instanceOf, marine gas turbine engine]
-
A.
gas turbine engine
chosen
A gas turbine engine is a continuous-flow internal combustion engine that compresses air, mixes it with fuel, burns the mixture, and expands the hot gases through turbine and nozzle stages to produce mechanical power or thrust.
-
B.
military aircraft engine
A military aircraft engine is a high-performance propulsion system designed to power combat and support aircraft, optimized for thrust, reliability, maneuverability, and operation under extreme conditions.
-
C.
steam turbine-powered ship
A steam turbine-powered ship is a vessel propelled by one or more steam turbines that convert high-pressure steam energy into rotational motion to drive its propellers or waterjets.
-
D.
turbofan engine
A turbofan engine is a type of air-breathing jet engine that uses a large fan driven by a gas turbine to produce thrust through both accelerated bypass air and exhaust gases for efficient high-speed propulsion.
-
E.
gas turbine–powered car
A gas turbine–powered car is a road vehicle that uses a gas turbine engine, rather than a conventional piston engine, to convert fuel into mechanical power for propulsion.
- F. None of above.
Provenance (1 batch)
The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
