Rapidly Attachable Fluid Transfer Interface
Rapidly Attachable Fluid Transfer Interface (RAFTI) is a standard interface for transferring fluids, e.g., propellants, in space. It has been defined by a group of 30 companies. The interface specification has high and low pressure variants, both for operation between -40 °C and 120 °C. A first implementation is planned to be tested in space in 2021 as part of a prototype fuel depot. A free flying orbital demo was launched in June 2021 to test transfers of high-test peroxide.
