Ulster Rocketry: 100,000+ people introduced to rocketry and 500+ members and associated students in three years.
02 / The broken loop
Motor development still takes months.
Tooling, casting and curing make traditional development slow and expensive. The delay carries through the entire customer programme.
Long delivery times suppress iteration across launch, test and defence programmes.
03 / The iteration advantage
Speed is set by Design to Doorstep
To fail fast, customers need the full cycle to move faster: specification, engineering, manufacture, test and delivery.
SIRITH is building the integrated loop—not a standalone printer or another fixed motor catalogue.
04 / From profile to propulsion
SIRITH turns customer constraints into a custom motor geometry.
Physics-constrained automated design and proprietary low-temperature 3D printing remove tooling delay while preserving 3-dimensional variable geometry.
Input
Customer specifications and mission requirements.
Design engine
Physics-constrained automated motor design.
Print-cast
Integrated additive manufacturing process.
Learning loop
Feed test data back into the next design.
