CODEM Partners with B2Space: Leading the Next Revolution in Small and Micro-Satellite Launch Industry

Introduction

The partnership between CODEM and B2Space marks a significant advancement in the small and micro-satellite launch industry. Leveraging B2Space’s innovative “rockoon” concept, this collaboration aims to provide a cost-effective and flexible launch solution for satellites, addressing the exponentially growing market for small and micro-satellite deployments.

The Challenge

B2Space’s satellite launch solution is based on a disruptive concept combining a rocket and a balloon—termed “rockoon.” This stratospheric balloon platform lifts the rocket to 35 km altitude, above 99.9% of the atmosphere, from where the launcher is deployed. The challenge was to create a robust and reliable “Launch Tube” to house and deploy the rocket effectively under these unique conditions.

The Solution

CODEM’s engineering and manufacturing expertise were critical in developing the “Launch Tube,” a vital component of B2Space’s launch system.

Rockoon Concept

• Stratospheric Balloon Platform: Lifts a self-operative platform to 35 km altitude, bypassing the densest part of the atmosphere.
• Three-Stage Rocket: Deployed from the balloon platform, dramatically reducing launch costs and providing greater flexibility for satellite deployment.

Launch Tube Design

CODEM manufactured the “Launch Tube,” ensuring it met stringent requirements for housing a 122mm diameter x 1,980mm projectile to be launched from approximately 30 km altitude on a sub-orbital trajectory.

• Load Transfer Frame: The “Launch Tube” is attached at key locations to this frame, which suspends during the mission.
• Fixed Angle of Attack: The tube is oriented at an angle ranging from 42° to 78°.
• Environmental Sealing: Utilises a “blast away” material fixed to an “End Cap” and a press fit with the subcomponent “Rocket Fairing” to ensure it remains sealed.
• Composite Materials: The body is made from non-flammable, extreme temperature-resistant composite materials.
• Thermal Management: Maintains a given thermal environment and prevents heat loss during the ascent stage at approximately 30 km altitude.

Benefits and Impact

Cost Savings and Flexibility

• Reduced Atmospheric Drag: Launching above 99.9% of the atmosphere saves significant costs by skipping the densest part.
• Customizable Orbits: Satellites can pick their orbits and control the launch schedule without design constraints as secondary payloads.
• Affordability: Provides a low-cost platform for developing new technologies, making space access more affordable.

Innovation and Reliability

• High-Performance Materials: Use of advanced composite materials ensures reliability and safety during the launch.
• Environmental Control: The “Launch Tube” design effectively manages thermal conditions and maintains the integrity of the launch system.

Conclusion

The collaboration between CODEM and B2Space exemplifies a revolutionary approach to satellite launches, combining innovation with practical engineering solutions. By developing a robust “Launch Tube” and leveraging the rockoon concept, CODEM and B2Space are making significant strides in providing flexible, cost-effective, and reliable access to space for small and micro-satellites.

This partnership not only addresses current market demands but also sets a new standard for future satellite launch solutions, highlighting CODEM’s role in advancing space technology and sustainable manufacturing practices.
