TECHNOLOGIES
ENGINE
ZERO is a bipropellant rocket that uses liquid bio-methane as fuel and liquid oxygen as an oxidizer. This represents Interstellar's first use of a gas generator cycle, where part of the propellants is burned in a gas generator to drive a high-speed turbopump. This turbopump operates at tens of thousands of rotations per minute, delivering fuel to the combustion chamber under high pressure. The rocket also employs regenerative cooling, utilizing the fuel to effectively cool the combustion chamber walls. The engine for ZERO has been named COSMOS by the development team, inspired by the COSMOS flower, the official flower of Taiki. The engine's pintle injector spray pattern resembles the petals of this flower, making the name a fitting tribute.
PROPELLANT TANKS
Design, manufacturing, welding, and testing of the tanks are done at Interstellar. High-strength aluminum alloy is used for the tanks that will store the liquid biomethane fuel and liquid oxygen oxidizer. A proof and a burst pressure test were done to ensure its capability to withstand design pressures and to gauge the pressure endurance limits.
GIMBAL MECHANISM
Gimbal mechanism controls the direction of each engine and consequently the launch vehicle trajectory and orientation. This allows engine adjustments mid-flight, improving safety for the missions. This technology has been demonstrated in our suborbital launch vehicle MOMO.
AVIONICS
The avionics system serves a mission critical role in ZERO as it holds the responsibility of monitoring and controlling the safety of the vehicle. The architecture, mechanical hardware, electronic hardware, FPGA, and software development of the avionics system of ZERO are all done in-house at Interstellar.
