Introduction

We are embarking on an ambitious project to design a detailed 3D CAD model for the Iris-R2, a state-of-the-art, reusable rocket. The Iris-R2 is a revolutionary spacecraft that embodies cutting-edge technology, reusable engineering, and forward-thinking design principles. Our goal is to create a high-fidelity CAD model that serves multiple purposes: prototyping, technical simulations, visual presentations, and manufacturing support.

This model must represent the entire rocket, capturing both external and internal components with unmatched precision. We aim to utilize the model for functional simulations, aerodynamics testing, and as a visual tool to showcase the Iris-R2’s innovative features to stakeholders and engineers alike.

This proposal outlines the rocket’s dimensions, structural features, aesthetic choices, system functionality, and technical requirements for the CAD design process.

• Stage numbering on both stages for clarity.
• Safety labels and panel access markers.
• Heat Shielding:
• Hexagonal tiles covering the base of the first stage, designed for thermal re-entry protection.
• The heat shield pattern should include gaps for aesthetic realism but maintain seamless integration.
• LED Lighting:
• Subtle LED strips integrated near the grid fins and landing legs for visual enhancement during rendering.

2. Propulsion Systems

First Stage Engines:

• Details:
• Include intricate details such as turbopumps, injector systems, and nozzle cooling channels.
• Exhaust pipe routing and feed lines should be visible for realism.

Second Stage Engine:
• Type: Single vacuum-optimized engine.
• Design: Extended nozzle for high-altitude efficiency, with visible radiative cooling fins and throttle controls.

3. Structural Components

Landing Struts:
• Number: Four telescoping landing legs symmetrically placed.

• Details: Lattice-like design with visible pivot points for adjustment during descent.

Interstage:
• Material: Aluminum-lithium alloy, anodized silver.
• Purpose: Houses separation mechanisms, including pushers and stage connectors.
• Aesthetic: Visible reinforcements and cable conduits.

4. Payload Integration

• Design: No detachable fairing; payload housing is integrated into the second stage.
• Details for CAD:
• Internal seating or storage racks (optional, based on rendering requirements).
• A visible hatch for payload access with sealing mechanisms.

5. Materials and Texture Suggestions

• Body: Carbon-fiber composites with a matte finish.
• Engines: Alloy-based construction to withstand high temperatures and stresses.
• Grid Fins and Landing Legs: Titanium alloy for lightweight strength.
• Heat Shield: Ablative material tiles for lower stage protection.

Functional Features to Include in the CAD Model

1. Aerodynamic Considerations:
• Contours and surface smoothness to minimize drag.
• Proper alignment of grid fins for in-flight corrections.
2. Thermal Protection:
• Include heat shielding on the first stage, particularly around the engine section and the interstage joint.
3. Landing Mechanism:
• Dynamic modeling of landing strut deployment.
• Include shock absorber components for precision landings.
4. Separation Mechanisms:
• Detailed interstage design with visible push rods and connectors for stage decoupling.
