The `_engine_` library serves as the core analysis tool for engine data within UNICADO. It provides access to all possible engine data for every tool in UNICADO. The data can be fixed for an engine or at a given operating point. The data output depends on various factors such as the scale factor and power and bleed offtakes from the engine. The primary objective is to establish a **single source of truth** for engine data retrieval.

## Role in `propulsion_design`
Within the `propulsion_design` module:
- Engines for the aircraft are selected, and their respective files are copied to the engine directory.
- The **scale factor** is calculated, determining how the engine's thrust is adjusted to meet aircraft requirements (refer to the `propulsionDesign` documentation).
- The **scale factor** is calculated, determining how the engine's thrust is adjusted to meet aircraft requirements (refer to the `propulsion_design` documentation).
The `engine` library applies this scale factor, ensuring that aircraft parameters can be accessed without further manual adjustments.
