TECHNOLOGY
ENGINE
Rocket engines often make up half of the total manufacturing costs. Introducing innovative manufacturing technology and design approaches, Interstellar's engines have been developed with remarkable cost-effectiveness compared to conventional rocket engines, while maintaining high-performance capabilities and facilitating mass production.
PINTLE INJECTOR
Overcoming the limitations of traditional pintle injectors, which often struggle to deliver sufficient performance, by reducing the number of components to one-tenth of conventional engines while achieving high combustion efficiency through design innovations.
WIRE-WRAPPING METHOD
An innovative manufacturing process ensuring short lead times and cost savings compared to conventional methods (patent pending).
TURBOPUMP SYSTEM
Developed in-house for cost efficiency, Interstellar's approach incorporates the latest technologies such as 3D printing into the components.
PROPELLANT
Interstellar's rockets employ liquid methane as a propellant, chosen for its high performance and affordability. With its manageable properties, methane offers excellent cost efficiency in both rocket production and operations. Additionally, the utilization of liquid biomethane from cow manure contributes significantly to carbon neutrality. This initiative not only addresses odor issues arising from manure in Hokkaido's dairy farming areas but also supports local energy self-sufficiency, enabling environmentally friendly development.
PROPELLANT TANK
Utilizing advanced aluminum welding technology, the fabrication of propellant tanks incorporates an in-house production process that encompasses design, manufacturing, and testing. This comprehensive approach ensures the achievement of cost reduction in the final product.
MECHATRONICS
The gimbal mechanism responsible for controlling the direction of the engine jets is a mechatronic component requiring advanced technology. This component is also utilized in Interstellar's suborbital launch vehicle MOMO.
AVIONICS
Interstellar's in-house production covers avionics hardware and software. Semiconductor technology from the automotive and general industrial sectors, combined with state-of-the-art technologies like 3D printing, enables lightweight and cost-effective component development.
