# Gas Turbine Cycle Analysis Skill

## Purpose
Provide comprehensive gas turbine engine thermodynamic cycle analysis capabilities for turbofan, turbojet, and turboprop engine design and optimization.

## Capabilities
- NPSS and GasTurb model setup and execution
- Component matching and off-design analysis
- Turbofan, turbojet, turboprop configuration
- Performance map generation and interpolation
- Bleed and power extraction modeling
- Transient performance analysis
- SFC optimization studies
- Engine inlet and nozzle integration

## Usage Guidelines
- Select appropriate component models based on engine configuration
- Validate component maps against available test data
- Consider off-design performance across the flight envelope
- Account for bleed and power extraction in system-level analysis
- Optimize cycle parameters for specific mission requirements
- Document assumptions and limitations for each analysis

## Dependencies
- NPSS (Numerical Propulsion System Simulation)
- GasTurb
- MATLAB

## Process Integration
- AE-004: Gas Turbine Cycle Analysis
