Chemical rocket performance is limited by the energy in the fuel (Is). Ion rocket performance is limited by the weight of its power source (а). An ion rocket can carry the greatest pay load provided it is permitted to operate longer than some critical time (tc) determined by а, Is, ...
The U.S. Air Force started the Upper Stage Engine Technology (USET) program to develop an affordable replacement for the RL10 hydrogen rocket engine. Development and production of the RL10, as well as other historical rocket engines, required large development teams with substantial labor costs ...
SpaceCAD lets you experiment with different design options to see how they affect your rocket's flight and stability. Try out different fin configurations, engine types, or recovery systems. Get ready for a level certification To fly larger and bigger rockets, you need a certification. This requi...
HYPROB aims at developing competences to consolidate the national background on rocket-engine systems for future space applications. Since nowadays liquid methane represents an innovative fuel in aerospace propulsion, one of HYPROB's objectives is the development of a simulation tool for the ...
Integration of computational fluid dynamics (CFD) for design and analysis of turbomachinery components is needed as the requirements of pump performance and reliability become more stringent for the new generation of rocket engine. A fast grid generator, designed specially for centrifugal pump impeller,...

The BE-4 engine is key to Blue Origin’s spaceflight ambitions. Besides building it for the likes of ULA, the booster will also power Blue Origin’s own reusable New Glenn rocket, which is currently in development. ULA’s Vulcan Centaur vehicle uses two BE-4 engines in the first stage...
Among them, the YF-102 is the country's first open-type liquid oxygen-kerosene engine, and made its maiden flight on April 2 as the engine used for China's first commercial liquid-fueled carrier rocket, Tianlong-2. The other two rocket engines are the YF-102V and the YF-209,...
