Vehicle Architecture
Fuel and Oxidizer
Fuel and oxidizer are chosen to provide the simplest, most accessible, and least costly liquid propulsion system.
Interfaces
The standard method for integrating standard Half Cat style rockets provides a robust, reliable structure. Critical interfaces include:
2x2 attachment of thrust chamber to propellant tank
Clean airframe mating to propellant tank
Motor Design
Liquid bipropellant rockets can be easily scaled and customized to a degree largely unattainable by other propulsion systems. To aid in this process, Half Cat Rocketry has laid out guidelines and recommendations, and developed a simulation program to streamline standard liquid rocket design.
O-Rings and Gland Design
O-rings are a common type of seal in rocket motors. Based on years of experience, Half Cat Rocketry has simplified O-ring selection and gland design for standard liquid rockets.
Ports and Fittings
Fittings provide sealed unions between parts. Broadly, these fall into the categories of pressure ports and tube connections.
