Business Plan
By utilizing hybrid rocket technology that employs a solid fuel and a liquid oxidizer, and using plastic as the fuel, we aim to develop a propulsion system that offers thrust comparable to that of liquid propulsion systems, while eliminating the risk of explosion. This results in a safe and high-thrust solution. By addressing the issues of explosiveness, danger, and high cost inherent in existing engines, our mission is to develop cutting-edge engines for fast and safe space travel.
Research Outline
In the initial market, the goal of this project is to conduct a subscale space demonstration, with the aim of eventually providing a propulsion system for maneuvering in space that enables safe orbital transfers. This system will initially target small spacecraft with a mass of 200 kg or less, and later expand to support larger spacecraft exceeding 200 kg.
