This tutorial aims to provide a comprehensive overview of the Neutron launch vehicle’s design, the significance of the Archimedes engine, and the production processes involved, making it essential reading for aerospace engineering students, industry professionals, and space enthusiasts alike.

1. Introducing Rocket Lab and the Neutron Launch Vehicle

Rocket Lab is known for its rapid innovation in the aerospace sector, primarily through its Electron launch vehicle. The Neutron is a medium-lift, partially reusable orbital launcher that enhances Rocket Lab’s capabilities for satellite deployment. With a payload capacity of 13,000 kg to low Earth orbit (LEO), it is optimized for the increasing demand from megaconstellation missions.

2. The Significance of the Archimedes Engine

The Archimedes engine is a pivotal element of the Neutron launch vehicle. Here’s how it stands out:

• Propulsion System: Utilizing a liquid oxygen (LOX) and methane propellant system, the Archimedes engine operates on an oxidizer-rich gas generator cycle, producing 1 meganewton of thrust and achieving a specific impulse (ISP) of 320 seconds.
• Configuration: The engine arrangement comprises nine units in the first stage and one vacuum-optimized version in the second stage, enabling high performance and efficiency in launch operations.
• Reusability Focus: Engine design emphasizes reliability and reusability, featuring many 3D-printed components for swift manufacturing and testing. This is expected to streamline the development process and reduce costs.

3. Overview of the Production Process

Rocket Lab employs cutting-edge technology and facilities to manufacture the Neutron and its components:

• Automated Fiber Placement (AFP): This technology enables rapid and precise construction of carbon composite structures at Rocket Lab’s Space Structures Complex in Maryland. AFP significantly decreases production time and increases efficiency.
• Engine Development Complex: Located in Long Beach, California, this facility is dedicated to the high-rate production of the Archimedes engine and ensures quality and reliability in engine manufacture.
• Assembly and Integration: In the Mid-Atlantic Regional Spaceport, Rocket Lab’s Neutron Assembly & Integration Complex facilitates the assembly of the rocket and refurbishment of returned first stages, preparing them for reflight.
