Target predicate: hasTypicalSpecificImpulse Context triple: [Hall-effect thrusters, hasTypicalSpecificImpulse, 1000–2500 s]
-
A.
specificImpulseSeaLevel_s
Indicates the specific impulse of a propulsion system, measured in seconds, when operating at sea-level conditions.
-
B.
specificImpulseVacuum_s
Indicates the specific impulse of a propulsion system when operating in a vacuum, expressing how efficiently it converts propellant into thrust under vacuum conditions.
-
C.
specificImpulseVac_s
chosen
Indicates the vacuum specific impulse of a propulsion system, expressing its efficiency as thrust produced per unit of propellant flow in a vacuum environment.
-
D.
specificImpulseSeaLevel
Indicates the specific impulse (thrust efficiency per unit propellant flow) of a propulsion system when operating at sea-level atmospheric conditions.
-
E.
specificImpulseVacuum
Indicates the specific impulse of a propulsion system measured under vacuum conditions, representing its efficiency in producing thrust per unit of propellant flow in space.
- F. None of above.
Provenance (3 batches)
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.
