data_map = {"13p4": "Atmos_13p4_SubsonicLateralSideStepF16"}

Mapping from check case identifier to subdirectory.

FlightData

NESC flight simulation data.

Flight simulation data from an NESC atmospheric check case. This is a subset of the original data. Not all check cases contain the same variables and only variables relevant to InertialSim are loaded from the source data.

Attributes:

time	NDArray
attitude	NDArray
position	NDArray
velocity	NDArray
angular_rate	NDArray
gravitation	NDArray

load

load(
    directory: Path | str, check_case: str, simulator: str
) -> FlightData

Load NESC atmospheric flight simulation data.

Data is available from the NASA Enginering and Safety Center site (see link in module documentation). Data is organized by atmospheric and orbital categories. Only atmospheric data is supported. Each check case has several available simulators.

Source data is in US customary units and is converted to SI units here.

Parameters:

Name	Type	Description	Default
directory	Path | str	top level directory with NESC atmospheric check case data organized in subdirectories with original names.	required
check_case	str	Check case identifier (e.g. "13p4").	required
simulator	str	Simulator number (e.g. "02").	required

Returns:

Name	Type	Description
flight_data	FlightData	Simulated flight data from the requested check case and simulator.
