Bellatrix Aerospace highlights that the majority of propulsion failures originate not in the thruster itself but in the supporting subsystems such as tanks, valves, feed lines, and power electronics. These subsystems form a chain of critical components where the structural integrity and pressure are paramount.

If any element in this chain is outsourced, mismatched, or poorly integrated, the propulsion system inherits external tolerances, delays, and failure modes which can compromise mission reliability.

Bellatrix adopts a fully vertically integrated approach where every subsystem is designed, manufactured, and tested in-house. This approach eliminates dependencies on external vendors and black box parts, enabling a unified engineering stack and an end-to-end data model to maintain a consistent performance baseline.

Vertical integration thus goes beyond a branding statement; it offers a tangible reliability advantage by ensuring tight control over the entire propulsion system.

The integration of subsystems under one roof allows Bellatrix to manage the system holistically, maintaining control from tanks through to thrusters. This reduces complexity and risk related to incompatible components and supply chain delays.

It also demands rigorous evaluation of not just part specifications but also the capability, load management, internal culture, and long-term stability of any vendor, factors not typically found in datasheets but crucially evident in orbit.

Bellatrix’s propulsion technology portfolio includes green chemical and electric propulsion systems tailored for small satellites, underlining their capability to innovate while maintaining strict quality standards.

Their in-house design and manufacturing capability facilitate agile deliveries and a shorter lead time compared to industry norms, offering satellite manufacturers compact, customisable, and cost-effective propulsion solutions.

This comprehensive control over the propulsion chain reflects Bellatrix’s strategic focus on eliminating subsystem vulnerabilities to achieve mission success. Controlling every subsystem empowers them to reliably control the entire mission, underscoring the importance of end-to-end system integrity in modern aerospace propulsion systems.​
