this thing is INSANE…
Check out this test which may be used in future space missions by NASA. In the last year or so, NASA has made a lot of headlines with the discussions and tests of new kinds of propulsion systems. They even tested an EM Drive propulsion successfully which is a “microwave” based system although don’t use it to make popcorn 😉
Here is an intro on the XRS-2200:
This engine was designed to be modular and was going to power the long since cancelled X-33 Venture Star. I knew I had seen a video of this before but I couldn’t find it anywhere. Found it finally through a dead hotlink to a Marshall Space Flight Center (MSFC) news release still on their server but it doesn’t turn up under any Google or NASA site searches for Aerospike. This video is property of NASA so if they request it to be removed I will do so. It was filmed in late 2000 or early 2001 and I believe this is 80% of max thrust.
Let’s watch them fire this thing up in the video on page 2
Pretty neat!
Right
Research programmable magnets…see if you can find anything about them or how bad the navy wants them.. you’re welcome
Aerospike engines use less fuel/thrust than traditional bell nozzles. As for the test frame, any flex would be a very bad thing for the frame during a hold down test.
Realism
Rocketdyne did extensive aerospike testing in the 60s. The XRS-2200 was to be used on the X-33, and was cancelled in 2001. Nothing new.
LH2 and LOX aren’t fossil fuels….
I find that it being tested and had some modifications is definately new and interesting. It was cancelled, so it wasn’t used. Now it is.
Because of control/power issues… Or just an overall cost decision
This has been around since the 80s
There wasn’t enough testing to use on the space shuttle program at the time
Wow
It was dropped then when STS stopped being an SSTO. Rocketdyne, who did the initial aerospike research for the USAF Project Isinglass, was also the SSME contractor.
The linear aerospike above was developed for the X-33 (which was also an SSTO) which was cancelled in 2001. The construction techniques being used for the fuel tanks made it too heavy.
Thank you.
Always nice to learn… Just hope the money that was invested into the scrapped project was with the knowledge they gained producing it.

Pretty badass!
I’m glad all of you read. Think about a rechargeable fuel in space. Solar powered microwave jet compulsion engines.
Jim You’re no alone. You & I have a theory. We can prove it.
Josh Young it makes sense to me…
The what?
Whoop-de-doo! Designs been around since the 60s. It’s just a more efficient rocket engine. Still runs on rocket fuel. Sad big oil and powers to-be got everyone by the balls and this is all they will release after 60 years.
Indeed
Yea.. lack of proof.. except for every rocket ever launched. Especially since cameras of all types have been on rockets since the mid-80s. Also high altitude balloons, the ISS, anyone with a telescope, or half a brain. Don’t confuse your ability to shove your head in the sand as a lack of proof.

Show me 1
This thing is actually pretty old, was gonna power the real replacements for the Shuttle, the Venture Star. Cool idea, too bad the program got squashed due to funding issues

No, it mentioned the EM drive which is a microwave based drive. The engine being tested in the video is not the EM drive and still runs on rocket fuel. Not trying to be a know it all, I simply saw an error in your statement suggesting that you misread the article.
Joshua Dupree Sr. Judging by your chosen use of the word “firmament” I have to assume that you are a Bible believer. More to the point, because your religious affiliation does not necessarily dictate your cognitive ability, your statement suggests a level of profound ignorance and self deception.
More than likely, you believe that scientific advances are simply “lies of the devil” or some other similar nonsense. If that is the case, why are you utilizing these advances (i.e. your smartphone or computer that you use to access the internet). Which brings me finally to the proof you so greatly desire. You hold proof in the very palm of your hand. (assuming you have a smart phone). You have a device that allows you to connect to a global network, it can provide you with gps coordinates of your exact location on the planet using satelite technology that lies IN ORBIT around the planet, IN space. You cannot, if you are to be honest with yourself, continue to deny the world around you. In fact, it takes a strong act of willful ignorance to claim what you do. I do not even know if you will ever read this, nor do I believe that you will care what I have to say, but it had to be said. Ignorance cannot go unanswered. It cannot be ignored. I hope you at least think about what I have said instead of dismissing it out of hand, as you are likely inclined to do. Perhaps you will be able to broaden your horizons. Good day.
Um don’t? Or doesn’t lol
^^^ beautiful response !
Which part of your statement are you open to hearing you’re wrong about. I’ll start with satellites. They do not exist. I challenge you to go to the NASA or USGS and get me a picture from them that isn’t tampered with. You will not find one. I am by no means religious. I use the word firmament because that is the best way to describe it. Everything we have been indoctrinated to believe is outright false. How is it with all these satellites in orbit, NASA cannot provide 1 unaltered image of the earth? The scientists that you cling so desperately to claim that earth is not a perfect sphere yet every picture we have of earth shows a perfect sphere. Explain
As I suspected, you fail to see logic. And I think I am beginning to understand where your stance comes from. I’m not sure what sort of life you have lived to induce such paranoia, but I suggest getting some sort of counselling. And I do not cling to scientists, only sound science and reason. What you failed to understand about my first point is that the systems you use today would be impossible if we did not have a satellite network. I believe someone mentioned earlier that you can even see satelites and the international space station when they pass overhead. This is true. You can see them much easier with even a small teliscope.
As to your perfect sphere claim, I would like to first point out that a 2 dimentional image taken from orbit from any orbiting body would make it apear as a sphere because of perception.
Second, you are aparently not aware of the effects of gravity on our planet. Understand that when a teacher or scientists explains that the earth is not a “perfect sphere” that doesn’t mean you should expect pictures of it to look like an egg. These changes are so slight it is easy to just look at a picture and say “well, looks round to me” and call it a day. That is not only the height of ignorance, but of arrogance.
The reason the earth is not a perfect sphere is because as the earth occupies its place in space and is acted on by gravity, which pulls hardest at its equator. Earth has a degree of plasticity to it. Imagine holding a rubber ball between your thumb and index finger. Now press on the top and bottom slightly, the top and bottom signifying the poles. Do this until the ball is just slightly mishapen. At first glance, the ball appears to be a sphere, but if you were to examine closely you would see that it was bulging slightly on its sides or at its equator.
Now apply this mental image to the earth, except understand that instead of pressure, gravity is acting upon it. And instead of being pressed together, the earth is being tugged at the equator so that its mass slightly buldges there. Notice I said slightly. It doesn’t matter if this bulge is only a few centimeters, I can no longer say that the earth is “perfect” if I am to use exact terms. And that’s the beauty of the thing, really. Ever heard the term “down to a science”? There is a reason that science is associated with precision. So instead of being nitpicky, and focusing on the fact that a scientist said the earth wasn’t a perfect sphere, why don’t you do an actual thought experiment and ask WHY they said what they said. Don’t just be satisfied with “well, looks round to me”. This is at the very nature of scientific inquiry, something you do not seem to understand. You might as well be a flat earther from where I stand, because your logic follows the same incongruous route as theirs. I could show you the numbers, show you the science. I could explain to you all day why your arguments are faulty, but I won’t because in the end your willful ignorance will win the day. As I said previously, good day. I hope you never teach a science class.
I’m still waiting for your proof
Then why are all NASA pictures showing a perfect sphere Phillip Powell?
A 2 dimensional pear on a counter still looks like a pear in a photograph. Doesn’t magically look like a sphere because of perspective
If all you have is to parrot what you’ve been told, then the fluoride has got you
You sir are an incredibly fascinating study of the willful suspension of disbelief. In no way will I argue with your ignorance despite the sick feeling in my stomach as I read your posts.
Phillip Powell Yes, I did misread the whole article. Thank you for letting me know this!! have a great day! Imagine if an engine were to be powered by electricity thought that could have enough power to go to the moon and safely land back.
Ignorance is bliss isn’t it Steven Teixeira
Ah yes… the areospike engine… here’s some good info on it — https://en.wikipedia.org/wiki/Aerospike_engine
Wow….seriously? Joshua you sir are a freaking idiot.
Why waste the gas and create pollution?
I’m not entirely sure you know what rocket fuel is made from. It has nothing to do with the petroleum industry.
That concept might work well incorporated into a wing how awesome would that be
it’s
It’s idiotic to believe we spin at 1000 miles an hour which keeps the water on this ball yet small fish can swim in the same water almost effortlessly.
It’s idiotic to believe in a plane flying west at 500 mph we’d reach out destination when our earth is spinning eastward at 1000 mph
