We fired a really cool rocket engine - and broke some records while we were at it. 🔥This Rotating Detonation Rocket Engine produced more than 4,000 pounds of thrust, and included a 300-second continuous burn, which is believed to have set the record for longest duration hot firing of... show more

300 seconds is serious duration for an RDRE. Always wondered how you managed the thermal cycling on the chamber walls. That unsteady heat flux usually kills these runs early.

@SciGuySpace What are the benefits of a rotating detonation engine over a more standard (albeit advanced) engine like the Raptor?

Astrobotic 的头像

Astrobotic5 个月前

RDRE's use continuous detonation waves instead of steady combustion to extract more energy from the propellant & potentially reduce fuel consumption for the same thrust. This would help lower weight and improve performance. In aerospace, every ounce counts! More ounces available = send more science!

What if you ribbed the spike, creating a tiered shockwave of knitted chakrams at one of the stable checkered pattern offsets? Like incrementally smaller cones amounting to same total length just you have a recessed ring/valley from which the next spike protrudes, creating a denser profile.

There’s a new rocket engine on the block 👀🚀 Astrobotic just announced that its newly developed “Chakram” Rotating Detonation Rocket Engine successfully completed its first test campaign. RDREs have long been theorized as a highly efficient form of propulsion, but only in the last five years or so have they started becoming reality. They work by sustaining supersonic rotating detonation waves inside the engine, helping improve efficiency across a range of operating pressures. Chakram produced more than 4,000 pounds of thrust and fired for 300 seconds during testing. Astrobotic

What’s hotter than a Texas summer? Our Miranda engine.🔥 We fired our Miranda engine at full power for 226 seconds— that’s almost 4 minutes! This endurance test verifies that the engine can perform beyond the nominal flight duration, meaning this engine is one step closer to being ready for flight. Seven of these Miranda engines will generate the thrust needed to lift our Eclipse rocket off the launch pad and propel it into orbit.

I've come to appreciate boring hotfires. Our BE-7 team recently completed a 2,500 second hotfire test at 10klbf on a development engine, setting the record for the longest-duration turbo pump-fed liquid rocket engine hotfire. This built on some of the most rigorous testing in the history of propulsion, with the previous record set by the RS-25 engine that powered the Space Shuttle. They recorded two 2,017 second tests in 1988. It's not lost on us that we're following a path those engineers blazed, and we're grateful for it. Grab the popcorn and enjoy watching 41 minutes of hotfire goodness.

🔥🚀 What if an engine could turn explosions into continuous propulsion? NASA is exploring rotating detonation engine technology, where a powerful detonation wave races around a circular combustion chamber instead of burning fuel in a conventional, steady flame. The result is an extremely rapid combustion process that can potentially improve propulsion efficiency and reduce engine complexity. It’s a radical idea: controlled explosions moving at incredible speed to push spacecraft and aircraft forward. 🌌⚡

Elon Musk on Raptor 3 Engine: "Raptor 3 is designed to require no basic heat shield, saving a lot of mass on the bottom and actually improving reliability, so that if there is, for example, a small fuel leak from the Raptor engine, it will simply leak into the existing flaming plasma and not really matter, whereas a fuel leak when the engines are contained in a box is a very scary thing indeed. It will be a massive increase in payload capability, in engine efficiency and in reliability. So this is really a revolutionary engine. Raptor 3 is really, I'd say, kind of alien technology, rocket engine. So in order to make the engine like that, we had to simplify so many parts of the design, incorporate secondary fluid circuits and electronics in the structure of the engine itself, so everything is contained and protected. It is a marvel of engineering."

$RKLB Neutron will be the largest carbon fiber structure to ever fly once it's completed. Some critics say it's not realistic because it would be the first carbon fiber structure of that size to fly, but I'd argue Rocket Lab is pretty good at firsts: "We were the first to 3D print a rocket engine and put it into orbit. We were the first to do an all carbon composite rocket and put it into orbit. We were the first to do all fiber optically networked avionics suite on a launch vehicle and put it into orbit." — Sir Peter Beck, Rocket Lab CEO

I've kept a pretty low (online) profile of what I'm building, but word's getting out. My company Astro Mechanica has invented a new kind of jet engine. Unlike any existing engine, it's efficient at every speed. Because it's efficient at every speed, we can use it in a new way: as the first stage of an orbital launch vehicle. The resulting platform will get payloads to orbit dramatically cheaper than all-rocket systems - among many possible applications. The key insight is to use electric motors to drive a compressor. That way we can make it spin at any speed, allowing it to "adapt" to it's airspeed and combustion cycle. One of the coolest parts: the video below is of a demonstrator my team and I built last year. We already have a new engine with 10x the thrust that will be complete next month.

With rocket engines, boring is good. To that end, please enjoy this 1,030-second (17+ min!) BE-7 engine burn. This test represents the Apogee Raise Maneuver or ARM burn for our Blue Moon Mark 1 Lunar lander, plus margin, the longest burn required by the mission to reach the Moon. You may have noticed that the engine for this test does not have a nozzle. BE‑7 is tested in both vacuum and atmospheric conditions. This test was at GEEx—our atmospheric test position in West Texas.
