# Overview of Micro Turbojet Design

In this course, you will learn how to model a fully parametric micro turbojet engine using nTop. By using custom blocks, you can create a modular workflow that can be easily reused in other notebooks. This approach leverages robust implicit geometry to enable rapid design exploration and performance optimization.

## Course Curriculum

The curriculum is organized into four lessons, each focusing on a key stage of the engine's development.

1. **Parametric Impeller:** Learn best practices for creating stable geometry using Signed Distance Functions (SDFs). This lesson covers vane generation, exponential twist rates, and robust trimming techniques.
2. **Combustion Chamber:** Explore the use of parametrized polylines and profiles. You will learn how to create complex cooling hole arrays and utilize list processing to manage multiple internal features.
3. **Parametric Bladed Disk (Blisk):** Focuses on modeling turbine wheels, including the precise control of blade curvature and the integration of aerodynamic profiles with the central hub.
4. **Parametric Housing and Component Placement:** The final lesson covers the assembly of all engine components. You will learn how to parametrically place modules and design the engine housing to complete the micro turbojet.
