test_FD001: NASA Turbofan Engine Degradation Simulation Test Data (Subset FD001)

Description

Truncated time series data from turbofan engine degradation simulations, generated using the C-MAPSS (Commercial Modular Aero-Propulsion System Simulation) model. This test dataset contains operational sensor data up to a point before failure, intended for validating prognostic algorithms that estimate Remaining Useful Life (RUL).

Arguments

Format

A data frame with multiple observations (rows) on the following 24 variables (columns):

unit: Engine unit number (identifier)
t: Time in cycles
T2: Total temperature at fan inlet (°R)
T24: Total temperature at LPC outlet (°R)
T30: Total temperature at HPC outlet (°R)
T50: Total temperature at LPT outlet (°R)
P2: Pressure at fan inlet (psia)
P15: Total pressure in bypass-duct (psia)
P30: Total pressure at HPC outlet (psia)
Nf: Physical fan speed (rpm)
Nc: Physical core speed (rpm)
epr: Engine pressure ratio (P50/P2)
Ps30: Static pressure at HPC outlet (psia)
phi: Ratio of fuel flow to Ps30 (pps/psi)
NRf: Corrected fan speed (rpm)
NRc: Corrected core speed (rpm)
BPR: Bypass Ratio
farB: Burner fuel-air ratio
htBleed: Bleed Enthalpy
Nf_dmd: Demanded fan speed (rpm)
PCNfR_dmd: Demanded corrected fan speed (rpm)
W31: HPT coolant bleed (lbm/s)
W32: LPT coolant bleed (lbm/s)

Details

Key characteristics of this test dataset:

Simulates progressive degradation in the High Pressure Compressor (HPC) module
Time series are truncated prior to failure (true RUL values not included)
Includes realistic measurement noise and unit-to-unit variability
