    Any thoughts?

    Wasted money and research....inefficient and rather pointless beyond cleaning a furnace.

    Pretty neat though.

    Russia first to test clean pulse-detonation rocket engine

    In a breakthrough move, Russian scientists have become the first ever to successfully test a pulse-detonation rocket engine (PDRE) on clean fuel, claiming this will be the future of space travel.

    The tests were run in July and August, but the announcement was only made on Friday on the homepage of the Russian Advanced Research Foundation (FPI), which is in charge of the project.

    The scientists say they have built and tested “the world’s first full-size pulse-detonation rocket engine demonstrator” that uses clean fuel, namely an oxygen-kerosene pairing.

    The current liquid fuel engines used by rockets to get to space have reached their maximum capabilities, according to the FPI. Instead, a pulse-detonation engine that uses high thermodynamic efficiency will allow spacecraft to reach previously unattainable performance.

    It would also result in additional workload for rockets and the reduction of cost for orbital deliveries.

    “We took up the challenge – to prove the possibility to create a detonation in oxygen-kerosene rocket engines. And now we can firmly say that this is possible, and we know how to do it,” Igor Denisov, the FPI’s deputy director, said in comments on the successful tests.

    Russia is a leader in developing PDRE technology, and the current project was launched back in 2014 under the auspices of Energomash, one of Russia’s key companies in space research.

    “The experimental studies have clearly confirmed the theoretical possibility of creating a national PDRE for a new generation of missile technology,” said Boris Satovsky, the chief of the project.

    “Many leading countries are involved in the development of detonation engines, but no one has so far yielded any serious results,” he added.

    The initial idea for the principles of the PDRE was thought up by Soviet scientists in the middle of the last century.

    Apart from Russia, the US is also involved in developing the technologies of pulse-detonation engines (PDE).

    Back in January 2008, it reportedly became the first to have tested a pulse-detonation engine, though powering a plane and not a rocket. The project was run through the US Air Force Research Laboratory, and the aircraft was then moved to the National Museum of the United States Air Force.

    The US used one in an aircraft in 2008.

    I am aware of the concept and technology to an extent, there is however a good reason it was shelved. Thus my commentary regarding the waste of time and resources. There is a reason the United States did not continue the program and instead gave away the prototype to a museum.

    Likely tests have been active in skunk works that no one will ever know about that led to our testing and dismissal.

    I think that it is one sides to believe that this technology is a waste of time just because US shelved a jet version of this project.

    Remember NK-33?

    It was developed by the Russian in the 70s. When they were discovered by more than 20 years later, these old soviet engines were shown to be smaller, more fuel efficient, and surpassed anything the west had at that time or was developing.

    Even 30 years later, this rocket engine surpassed anything new and was frequently used by NASA

    Taking history in to account; to use US as a measuring stick of whats possible or not and what is worth investing time in or not is very misguided.

    Its obviously not anywhere near as bad as you say if Russians are planning to use these engines

    Its obviously efficient enough for what the Russians have in mind for it

    And thats what we are looking at. Purpose

    This engine is not designed to send people to Mars and thus it doesn't need to be super fuel efficient.

    To quote RT.com
    It sounds like this engine is designed to make cheap orbital deliveries while delivering more at once.

    So with this engine, Russia could send more stuff into space for a cheaper cost. And as Satovsky pointed out, theh are looking to use this technology for missiles too. ICBM armed with this engine could carry more warheads.

    Its a true breakthrough since it could get more stuff in space for cheaper the cost. Orbital ship or satelite building might even be a possibly as it could actually become affordable.

    So while Russia is working on this breakthrough short ranged engines to easily get payloads into orbit, its also developing a nuclear rocket for longer range travel.

    Planned to be tested by 2018, it could get humans to mars in just 4 to 6 weeks.

    Yup....Russia seems to be great at "Planning" and saying it intends to do this or that. Not so good at actually doing any of those things though.

    There is no evidence for that. So far russia has been relitavely good at setting deadlines and meeting them

    S400
    S350
    T50
    Armata
    Hyper-sonic mussiles
    Etc

    The plans for a nuclear rocket was first announced in 2010.

    In 2010 they said that plans would be drafted by 2012. That deadline was also met.

    The fact that they did an update in March earlier this year means that everything is still going according to schedule. At least the dead line fir the testing announced back in 2010 is still the same.

    The fact that the deadline hasnt changeg from back in 2010 provides substantial evidence that everything is on track so far.

    That being the case and with the recent history of Russia meeting their dedlines, Id say that it would be baseless to say that they wont in this particular instance.

    Very funny to look at forumnyh talkers who do not have technical education ...
    ------------------------------------
    Boys, you first learn in Physics:
    - What is the "liquid fuels for rockets"
    - What is the "solid fuel for rockets"
    =========================

    Only fundamental physics ..
    Nothing personal

    Russian girls say in such cases:
    I get (*)(*)(*)(*) tea leaves from tea ..
    :smile:

    You'd better talk with Russian girls..
