Target class: ducted fan tail rotor Context triple: [Fenestron, instanceOf, ducted fan tail rotor]
-
A.
tandem-rotor helicopter
A tandem-rotor helicopter is a rotary-wing aircraft featuring two large horizontal rotors mounted one in front of the other, rotating in opposite directions to provide lift and directional control without the need for a tail rotor.
-
B.
turbine-powered helicopter
A turbine-powered helicopter is a rotary-wing aircraft that uses one or more gas-turbine engines to drive its main and tail rotors, providing lift, thrust, and control.
-
C.
piston-powered helicopter
A piston-powered helicopter is a rotary-wing aircraft whose main rotor is driven by one or more reciprocating (piston) engines, typically used for light-duty, training, or private operations due to their lower cost and complexity compared to turbine-powered helicopters.
-
D.
bladeless electric fan
A bladeless electric fan is a modern air-circulating device that uses hidden impellers and aerodynamic channels to produce a smooth, continuous airflow without exposed rotating blades.
-
E.
rotorcraft development program
A rotorcraft development program is an organized, multi-phase effort to design, test, certify, and field new or improved rotary-wing aircraft to meet specified performance, safety, and mission requirements.
- F. None of above. chosen
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.
