Stoke Space raises 1 billion dollars to continue with the development of its Nova launchers
Article excerpt
It includes plans for the unprecedented Nova Block 2 rocket, a more powerful system designed to transport up to 15 tons to low Earth orbit (LEO). The Nova Pathfinder is Stoke's first orbital launch vehicle. It is based on the same technologies that Stoke is incorporating into its Block 2 design. Both two-stage vehicles are being manufactured with total and rapid reusability in mind, with the Pathfinder serving as a testbed for this architecture. The Pathfinder's first stage is powered by seven Zenith engines, designed by Stoke. They use a full-flow staged combustion (FFSC) cycle and run on liquid oxygen and liquefied natural gas (LNG). The Nova Block 2's first stage will feature 14 Zenith engines. Stoke describes the FFSC cycle as “perhaps the most difficult to develop in rocket engines”. However, it highlights its advantages. The technology generates less waste (such as soot) around the engines and reduces maintenance needs between flights, according to the company. The upper stage of both rockets represents an unconventional approach to spacecraft design, compared to other vehicles in their category. The rear of Nova's second stage incorporates a heat shield to protect the vehicle during re-entry into Earth's atmosphere. It does not use the ceramic tiles historically used in the heat shields of previous spacecraft. The domed structure at the base of Nova's upper stage is...
