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

A louder rumble in Rocket City! We just completed our first BE-4 engine hotfire test at the historic Test Stand 4670 in Huntsville. We also continue to test BE-4 engines at our Texas facility. The BE-4 engine produces 550,000 pounds of thrust and is our most powerful engine yet.

Elon Musk: Raptor 3 is alien technology. “Raptor 3 is a massive increase in payload capability, in engine efficiency, and in reliability. This is really a revolutionary engine. Raptor 3 is really kind of an alien technology rocket engine. Even industry experts, when we showed a picture of the Raptor 3, said, that engine is not complete. Then we said, here's the engine, not complete, firing at a level of efficiency that has never been achieved before. That is one clean engine. 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, frankly.” From: SpaceX Update, May 27, 2025

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.

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."

🚨#BREAKING: Nearly 300 passengers on a Delta Airlines flight were forced to evacuate after an engine fire broke out 📌#Orlando | #Florida Watch as footage captured by a passenger at Orlando International Airport shows a A330 Airbus Delta Airlines flight from Orlando to Toronto experiencing an engine fire. The incident prompted an emergency evacuation of all 300 passengers on board. Emergency crews quickly responded and were able to extinguish the fire. The cause of the fire is currently unknown, but fortunately, no injuries have been reported at this time.

Jet engine Thrust test✅🔥🚀: Finally we have the data we need, at 100% throttle alone, the engine generated thrust of 7.2KG to 7.8KG (76.5 Newtons) At 100% throttle plus Afterburner it soared to 14KG to 16KG, I saw it peak at 18KG, but we'll take the average at 16KG thrust (157 Newtons) For this scale & build, I am a bit satisfied with the performance, although if I ditch the cooling design on the exhaust the thrust will increase significantly, but the exhaust will glow red hot, so we had to trade some thrust for better cooling for the engine. All the same, I am satisfied with the engine performance at this scale. I look forward to our runway tests⚡️ #Zedora #madeinEbonyi #madeinNigeria 🇳🇬

#WATCH | Shirdi, Maharashtra | NIBE CTO and Strategy Header Balakrishnan Swamy says, "Suryastra is a rocket launcher system with the capability to fire 150 kilometer and 300 kilometer rockets. Last week, we had a demonstration in Integrated Test Range (ITR) Chandipur where we were able to fire 150 kilometer with a CEP (Circular Error Probable) of less than three meter. Similarly, 300 kilometer rocket launcher and the rocket was also fired with a CEP of less than three meter. Today we have got an order from Indian Army under emergency procurement for the system, under which we have to give them two launcher vehicles procurement. one battery command post, and one loader vehicle...

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.

Stoke Space is developing a fully reusable rocket designed to reuse both its first and second stages. The first stage lands like Falcon 9, while the second stage returns to Earth after delivering its payload using a unique engine with 30 thrust chambers. Its actively cooled heat shield uses cryogenic fuel to protect the rocket during the intense heat of re-entry.

A Pratt & Whitney F100 turbofan is one of the most successful fighter jet engines ever built. First run was in 1972, it still powers the F-15 and F-16 more than 50 years later. Over 7,200 engines have been built, collectively logging 32+ million flight hours. At full afterburner, it produces up to 129 kN or 29,000 lb of thrust while burning roughly 800-900 litres of jet fuel every minute. The afterburner, it's a second combustion stage that ignites fuel in the exhaust stream to generate maximum combat thrust. This test cell isn't checking if the engine starts. It's measuring vibration, temperatures, pressures, fuel flow, and thrust while a machine producing 29,000 pounds of force is bolted to the ground. What here looks like a routine engine test is actually one of the most demanding demonstrations of precision engineering in aerospace, Each brand new F100 engine is worth roughly $5-8 million, reflecting five decades of continuous refinement in fighter propulsion. 🎥kaydenh0dge
