    On July 19, 2006 Rocketdyne announced that the demonstrator engine front-end had been operated at full capacity. [3]According to NASA, the Integrated Powerhead Demonstrator project was the first of three potential phases of the Integrated High Payoff Rocket Propulsion Technology Program, which was aimed at demonstrating technologies that double the capability of state-of-the-art cryogenic ...

    This combination is widely regarded as the most practical for boosters that lift off at ground level and therefore must operate at full atmospheric pressure. LOX and liquid hydrogen. Used on the Centaur upper stage, the Delta IV rocket, the H-IIA rocket, most stages of the European Ariane 5, and the Space Launch System core and upper stages.

    Parsons (dark vest) and GALCIT colleagues in the Arroyo Seco, Halloween 1936.JPL marks this experiment as its foundation. [22] [23]In hopes of gaining access to the state-of-the-art resources of Caltech for their rocketry research, Parsons and Forman attended a lecture on the work of Austrian rocket engineer Eugen Sänger and hypothetical above-stratospheric aircraft by the institute's William ...

  7. Spacecraft propulsion - Wikipedia

    en.wikipedia.org/wiki/Spacecraft_propulsion

    For rocket-like propulsion systems, this is a function of mass fraction and exhaust velocity; mass fraction for rocket-like systems is usually limited by propulsion system weight and tankage weight. [ citation needed ] For a system to achieve this limit, the payload may need to be a negligible percentage of the vehicle, and so the practical ...

  8. Reaction engine - Wikipedia

    en.wikipedia.org/wiki/Reaction_engine

    A reaction engine is an engine or motor that produces thrust by expelling reaction mass (reaction propulsion), [1] in accordance with Newton's third law of motion.This law of motion is commonly paraphrased as: "For every action force there is an equal, but opposite, reaction force."

  9. Pulsed plasma thruster - Wikipedia

    en.wikipedia.org/wiki/Pulsed_plasma_thruster

    A pulsed plasma thruster (PPT), also known as a Pulsed Plasma Rocket (PPR), or as a plasma jet engine (PJE), is a form of electric spacecraft propulsion. [1] PPTs are generally considered the simplest form of electric spacecraft propulsion and were the first form of electric propulsion to be flown in space, having flown on two Soviet probes ...
