Science and technology, explained simply
Scottish engineers have shown a prototype of one of the rocket stages that burns itself for flight, which replaces up to 16 percent of its fuel. So far, the prototype has not been tested for flight, but only as a demonstration of the thrust that can be generated by the rocket’s self-immolation. However, in the […]
The ATHENA miniature engine, developed by a team led by Daniel Perez Grande of IENAI Spain, is ready for production. A distinctive feature of the ATHENA engine is its adaptability and its basis in nanotechnology with electrospraying. Each motor is equipped with seven emitter arrays containing 500 point emitters on silicon wafers. Electrically charged particles […]
NASA has tested the most powerful electric rocket engine in history. It is intended for the Lunar Gateway orbital station. Until recently, the most powerful electric rocket engine was a 4.5 kW propulsion system. Aerojet Rocketdyne’s solution was chosen for Lunar Gateway. The new electric rocket engine has a power of 12 kW. It was […]
