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 an RDRE engine to date. Watch it fire:

Ship 40 has performed its first Static Fire test in preparation for the lucky Flight 13. This appears to have been a single engine test, but came after a hold of nearly 20 minutes. Assuming they were intentionally allowing the propellant to warm up. This may have been the first realistic simulation of an in-space relight burn that SpaceX has ever conducted during ground testing. 🎥: Avid Space

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

One of the biggest challenges in hypersonic warfare is heat. At extreme speeds, temperatures around a missile can rise so high that the engine itself risks melting. And now, India may have achieved a major breakthrough in solving that problem. DRDO’s Defence Research and Development Laboratory has successfully completed a long-duration test of an advanced actively cooled scramjet combustor, with the engine reportedly operating for more than 1,200 seconds. In this video, we break down how scramjets work, why hypersonic weapons are becoming central to future warfare, and how India is rapidly advancing in one of the world’s most competitive defence technology races. #DRDO #hypersonic #HypersonicMissile #scramjetengine #iran #IranWar

Canada's first orbital-class rocket engine is now being manufactured! Our patent pending Hadfield-150 engine is the largest and most powerful rocket engine ever built in Canada, and the first known Canadian orbital-class engine to make it to this stage. The Hadfield-150 builds on everything we learned after years of painstakingly designing, manufacturing, and testing the Hadfield-10 series, our first regeneratively cooled and additively manufactured liquid rocket engine. Every engine test, both successful and unsuccessful on our Darkhorse test stand at Area 66, retired risk that's now carried straight into Hadfield-150 and sovereign orbital launch for Canada. A few details about the Hadfield-150 engine series: ✅ Designed to power Tundra and Tundra+, our light and medium-lift launch vehicles, and built to scale to Tempest, our larger reusable medium lift vehicle ✅ Manufactured entirely in-house, from design to print to test, for true sovereign launch capability ✅ Produced at Rocket Factory 1, on our expanding fleet of metal additive manufacturing systems at the AMA Lab, including the largest known metal 3D printer in Canada ✅ Designed for reusability and medium-lift scale from the outset, and built to significantly cut the time, infrastructure, manufacturing and cost iterative engine testing usually requires, with room to scale to even larger engines by leveraging the same design ✅ Capable of engine-out functionality, so losing one on an early flight doesn't have to mean losing the mission ✅ Optimized for Canada's Launch the North initiative, to deliver sovereign operational capability in a time and cost efficient manner Initial testing starts later this year at our new Blackhawk orbital engine test cell at Area 66, our private test range in Ontario. Stacked, integrated vehicle testing comes later at the Atlantic Spaceport Complex, our spaceport in Newfoundland and Labrador. Stay tuned for some exciting and fiery milestones ahead! 🚀🇨🇦 National Defence Defence Research and Development Canada Canadian Space Agency Transport Canada NGen Canada

India’s indigenous Kaveri dry engine has reportedly achieved 48.5 kN of thrust during high-altitude and flight trials in Russia, exceeding its 46 kN target. Developed by DRDO’s GTRE, the engine was tested at Russian facilities including CIAM and the Gromov Flight Research Institute, including trials on a modified Il-76 flying testbed. The dry Kaveri is being developed to power India’s Ghatak stealth UCAV. Testing evaluated the engine under different pressure, speed and thrust conditions, including high-altitude environments. The reported 48.5 kN result is an important milestone, but it does not yet mean the engine is fully certified for operational use. The next major step is certification and integration. CEMILAC will review the test data before the engine can move toward airworthiness clearance and prototype integration. If those stages are completed successfully, Kaveri could become a major step forward for India’s indigenous military aviation engine programme. #kaveri #KaveriEngine #amca #Ghatak #drdo

🚀 Every ballistic capability starts with a demonstration. Discover for the first time the firing video of the ballistic munition FLP-t developed by ArianeGroup and Thales Group! The successful test in May with the support from the Missile Testing Division of the French Defense Procurement Agency (DGA) confirmed much more than the performance of a new rocket that represents the upper echelon of artillery systems with a range of 150 km. It marked a first building block for a new conventional ballistic strike capability that addresses a broad range of operational requirements in an evolving strategic context. Developed in less than 18 months for the versatile and interoperable Thales X-Fire launcher, the rocket munition validated ArianeGroup's ability to rapidly design, build and fly a new sovereign ballistic system while demonstrating the accuracy and reliability of its technologies The test has underscored both ArianeGroup’s ability to master the physics of long range flights with high altitude ballistic trajectories and our industrial expertise, paving the way for the B-Strike line-up that encompasses ballistic missiles ranging up to 2500 km. At ArianeGroup, this is how we build our vision for sovereign deep-strike capabilities. #RocketMakers #Defence #BStrikeLineUp

I have something very special to share today! This is a hardware capture of maximqad's port of the Xash3D engine--which is compatible with the Half-Life engine--running on the Sega Dreamcast... ONLINE! Keep in mind this is EXTREMELY early in the days of the port, with no DC-specific graphics optimizations or hardware accelerated math routines yet, so performance still has a lot of room to drastically improve. Audio was literally just barely moved to the SPU for the first time just the other day too, so this is still all very incredibly new... ...but here it is! The engine that wouldn't even run without being on an emulator that also needed to emulate the extended 32MB RAM modification... now running on a stock Sega Dreamcast with online multiplayer connectivity and mouse and keyboard support! Fantastic work from maximqad! I really believe as this engine matures, it will be an incredibly powerful tool for Dreamcast developers and will potentially bring a lot of new software to the platform in the form of Half-Life engine mods!

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.

Q: In Australia, George [Russell] told the media that he would have travelled with you. Have you spoken with him about their engine? Lewis Hamilton: *smiles* Q: What do you think their advantage is? Lewis Hamilton: "Difficult to say. I mean, I don't have all the information, so I don't really know too much, but of course I asked him about the engine. And yeah, I assume they could be more efficient, maybe they are able to charge more, maybe they have more crank power." "And so we've just got to, rather than worry about what others have, we just have to work harder to try and extract more from the package we have. But I'm really proud of Ferrari and the guys back at the factory who have done such a great job to build the car and the engine that we have, which has been reliable, and we'll continue to develop it."

BREAKING: Mayor Zohran Kwame Mamdani just announced COGE (Commission of Government Efficiency) and he takes a shot at Elon Musk in the process. "COGE, COGE, yes. Now, Elon Musk manipulated the fact that so many people across this country want to see a government that is more efficient. He used that as a justification to simply slash and burn so much of the services that Americans rely on. What we are speaking about is a sincere fulfillment of a vision that ensures that city government is operating with the same level of focus that a working class New Yorker is when they're trying to balance their bills. And that means looking at the processes we have, that means looking at the procedures of city government, and that means looking at anything we can do to deliver a more efficient and more excellent government... It's just the name and what it should have been. I think government efficiency, these are words that somehow have been understood as if they are Republican priorities when in fact they are the priorities of anyone who believes in the public sector. And yet Elon Musk took that language and used it to cut as many jobs that were as critical as possible for so many of the neediest people across the country and across the world. Ours is going to be a focus on actually delivering efficiency, not as a byword for cutting services, but actually a sincere commitment to efficiency."

This is the most powerful commercial jet engine currently flying on an operational airliner. The GE90-115B was built by GE Aerospace specifically for the Boeing 777-300ER. It weighs around 8.3 tonnes, has a 3.25 metre wide fan and produces up to 512 kN (115,000 lbf) of thrust from a single engine. To understand the sheer scale of that output, it produces roughly 2.7 times the thrust of the F135 jet engine powering the F-35, the most powerful fighter engine currently in service. The enormous fan at the front uses just 22 carbon fibre composite blades with titanium leading edges. At maximum thrust, it pulls in roughly 1.4 tonnes of air every second, with nearly 90% bypassing the core rather than passing through the combustor. At around 150 knots during takeoff, its 512 kn of thrust corresponds to roughly 39.5 MW of propulsive power, or in automotive terms around 53,000 hp from one engine. And it burns roughly 4-5 kg of jet fuel every second at maximum power conditions. Two of these engines are enough to power a fully loaded 777-300ER weighing more than 350 tonnes. Even if one engine fails after the critical point during takeoff, the aircraft is certified to continue the takeoff and climb on the remaining one GE90 engine. Each engine costs around $35-40 million. More than 2,500, GE90s engines have been built, and the GE90 family has accumulated nearly 130 million flight hours. And this is precisely why companies like GE Aerospace remain so difficult to displace in jet engines. There is never one breakthrough. GE spent roughly $2+ billion developing the GE90, chasing small gains across hundreds of systems, efficiency, materials, reliability and component life.

Denys Shtilierman Denys Shtilierman, co-founder and chief designer of the defense company Fire Point, on Ukrainian ballistic missiles: ▪️ "FP-7 - a range of up to 300 kilometers, with a warhead of up to 250 kilograms, depending on the distance." ▪️ "FP-9 - a range of up to 850 kilometers, with a warhead of up to 800 kilograms, also depending on the distance. Everything for the FP-9 is ready except the engine. Once the engine is finalized, we’ll have a clear understanding of the cost. This ballistic missile is expected by mid-year." "850 km-range ballistic missiles fly farther, carry more, and are cheaper than Iskanders. Their impact speed is one and a half times higher than that of the Iskander." On a massive strike on Moscow: ▪️ "I would certainly carry one out. Everything there is in very poor condition. And they [Russians] are still learning during the war. They have not yet intercepted ballistic missiles. They have never done it before. They have nothing to learn from. They will eventually learn to intercept ballistic missiles, but that will take time."
