Target class: cryogenic wind tunnel Context triple: [National Transonic Facility, instanceOf, cryogenic wind tunnel]
-
A.
wind tunnel
chosen
A wind tunnel is a controlled testing facility where air is driven past stationary objects to study aerodynamic properties such as lift, drag, and flow behavior.
-
B.
cryogenic instrument
A cryogenic instrument is a device designed to operate at extremely low temperatures to measure, manipulate, or observe physical phenomena with minimal thermal noise.
-
C.
liquid-cooled aero engine
A liquid-cooled aero engine is an aircraft powerplant that uses a circulating liquid coolant, typically water or glycol, to absorb and dissipate heat from the engine, enabling higher performance and more consistent operating temperatures than air-cooled designs.
-
D.
liquid-cooled aircraft engine
A liquid-cooled aircraft engine is a piston or reciprocating powerplant that uses a circulating liquid coolant, typically water or glycol, to absorb and dissipate heat from the engine cylinders and heads, enabling efficient temperature control and reliable operation in flight.
-
E.
ablative thermal protection system
An ablative thermal protection system is a heat shield that protects a spacecraft by sacrificially charring, melting, and eroding material to absorb and carry away extreme reentry heat.
- 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.
