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

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

Alastair Crooke: The US🇺🇸 may have signalled that it will resume nuclear weapons testing because Trump misunderstood a Russian missile test as a nuclear test ‘It seems to be based on a misunderstanding. Allegedly, Trump has proposed the idea of nuclear tests in response to Russian nuclear tests. But there hasn’t been a Russian nuclear test. The Burevestnik missile, that was publicised these recent days, like the Oreshnik. But this one has a nuclear power. It has got a propulsion system that is nuclear-based. Its warhead isn’t. There isn’t a nuclear warhead on it. It is a conventional warhead, but it is just instead of having a rocket propulsion, it has a nuclear drive that propels it. And this is why it’s able to stay aloft for a very long time, and in fact traverse the whole globe. But it’s nuclear propulsion, not a nuclear weapon. Did Trump understand that? Or did he just think this was a new nuclear weapon that Russia was testing? He probably didn’t understand that it wasn’t. It was just its propulsion mechanism that is nuclear, but not its warhead. Did Trump understand that? Or did he just think this was a new nuclear weapon that Russia was testing? He probably didn’t understand that it wasn’t. It was just its propulsion mechanism that is nuclear, but not its warhead. Now, whether the Russians have been testing underground before, I doubt it…I’m sure they would have taken every opportunity to say it if they thought they had detected Russian or Chinese underground tests.’ -Alastair Crooke, the former Middle East Advisor to the EU Foreign Policy Chief, on the latest episode of Going Underground FULL INTERVIEW BELOW IN THE REPLIES👇

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.

Success! 🚀 🇨🇦 At 3:45 PM EDT on Friday May 16th, 2025, we successfully tested both our new orbital Darkhorse engine test cell and our new third generation 3D printed Hadfield liquid rocket engine for the first time, marking a significant step towards Canada’s first commercial space launch. The test ran for 7 seconds at our propulsion test range, a company-owned secure site in Northeastern Ontario, successfully delivering nominal thrust, active cooling, and impulse results. This major test of the Darkhorse test cell and Hadfield Mk III engine lays the groundwork for NordSpace's Tundra orbital rocket, as the test cell is specifically designed to integrate with our turbo pump assembly in the next phase of propulsion development. Long duration tests are scheduled for the coming days, along with refinements to fuel mixture ratios and higher-pressure scenarios to test the limits of Darkhorse and our new engines. Minor upgrades and fixes to address a harmless leak in the cryogenic liquid oxygen line and design changes to our experimental control rods have already been made. Hot on the heels of our successful integrated test of our Taiga sub-orbital launch vehicle back in January, rapid developments and approvals at our spaceport in Newfoundland and Labrador, announcement of the SHARP (Supersonics and Hypersonics Applications Research Program), hosting the inaugural Canadian Space Launch Conference in Ottawa, and more - NordSpace is strengthening its position every day to ensure sovereign space launch is not just possible, but probable for Canada. Our historic first experimental flight is scheduled for 2025 from our spaceport, Spaceport Canada. NordSpace's CEO and founder, Rahul Goel, said “This successful test is not only a testament to NordSpace’s unmatched technical competency, but also to the success of our new project management framework, design philosophy, and engineering mindset used to deliver results for complex projects on time and within budget. Success on the first try with countless potential sources of failure is not common in the development of complex rocket systems, but our team succeeded by prioritizing first principles engineering. This test confirmed that we do have the right stuff, and that we will deliver this incredibly important sovereign launch capability for all Canadians. Like the land, air, and sea, space is no longer some final frontier for Canada. Space is an essential domain we must unlock, and launch a capability we must own. Without it, we are jeopardizing not only our security, sovereignty and economy, but are also relegating Canada to a participatory instead of a leadership role on the world stage. We must not let this happen.”

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."

There is a long checklist of items to go through before you get to hit the starter, so this clip is just the fun part. The engines are labeled engine #1 (left) and engine #2 (right). The first engine is started off the 24volt battery of the aircraft and the starter is released one the compressor reaches 55%. Once the first engine is up and running with the generator turned on, it makes the second engine spool up much quicker, as is has very little load to work against with the blades already turning at 85% rotor speed by this point. On odd calendar days we start engine number 1 first, and number 2 on even days. This is done to lessen the chance of us wearing out one engine more than the other. B212’s are intensive on maintenance, so each machine is dispatched with an engineer to oversee the maintenance. They will walk around the machine and check for (no) leaks for the first start of the day. 📸 by ig/bushpiloting Not an ad

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."

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."

Impromptu test on the Mark3 turbojet engine😎😂: The Ear Muffs are arriving next week, but again, I couldn't hold back but to run the engine at mild power today😂. I am probably the first person in Nigeria 🇳🇬 & probably all of Africa to build a self sustaining turbojet engine 🔥🤔, please correct me if I am wrong tho🙏🏻, but I doubt. Incase u don't know what a turbojet engine is, it is the engine that powers most fighter jets🚀. The engine is self sustaining because once it gets to idle speed, it runs at about 35,000 RPM on its own without the starter motor & batteries, and can only be shut down if the fuel supply is shut off, as demonstrated by my assistant in the clips. We will do a full power test with the afterburner next week when the ear Muffs arrive😎, so we don't go deaf🤣😂. We built this beast in Ebonyi State, Nigeria 🛠️⚡️ #Zedora #madeinEbonyi #madeinNigeria 🇳🇬

As the CFM LEAP engine shuts down, you can hear the distinctive “whoosh” sound followed by a gush of air. That is the Reverse Bleed System (RBS) at work. During normal operation, a significant amount of fuel remains unpurged in the system after engine shutdown. This residual fuel, located near or within the hot section, vaporizes due to high temperatures and deposits carbon (coke) on the fuel nozzles. Over time, nozzle coking leads to several operational and maintenance issues, including loss of thrust, reduced engine efficiency due to incomplete combustion, accelerated deterioration of hot-section components (combustor and High-Pressure Turbine), engine start failures, potential engine stalls, and increased unscheduled engine removals. The Reverse Bleed System (RBS) prevents fuel nozzle coking by automatically introducing cool air from the core compartment into the engine core flowpath after shutdown. This effectively lowers the fuel nozzle temperature below the coking threshold. RBS can operate for a maximum of 1 hour, and its effectiveness depends on ambient conditions (especially ambient temperature) and the total duration it runs. The last flight of the day contributes the most to fuel nozzle coke accumulation because of the extended dwell time at the gate. By actively managing post-shutdown thermal conditions, RBS significantly reduces coking-related problems, improves engine reliability, and lowers long-term maintenance costs. Now, also coming soon to the CFM56

After years of development, testing and refinement, we are printing one of our last Hadfield-10 rocket engines, a bittersweet moment 🫡 More of our team is transitioning toward getting our much larger orbital-class Hadfield-100 engine ready for the test stand, and getting Canada to orbit for the first time with our Tundra rocket. The pressure-fed Hadfield-10 series has been the backbone of NordSpace's propulsion program since our earliest days. It's the engine that proved we could design, manufacture, test and fly liquid rocket engines from scratch, entirely in-house, at the pace necessary to reach orbit. It powered our first successful hot-fire tests, survived our most demanding qualification campaigns, and gave our team the hard-won knowledge that no textbook or simulation could provide. It also powers our Taiga sub-orbital vehicle, which is taking flight in a few weeks. Every experimental lesson learned in its development from combustion stability, regenerative cooling, additive manufacturing, and test operations lives on in what comes next. That knowledge now flows directly into our turbopump fed Hadfield-100 engine, the most powerful rocket engine in Canadian history. Designed to power our orbital Tundra rocket to deliver 500+ kg to LEO and scaling further to 1,100 kg LEO in the Tundra+ configuration. Architected from day one to grow to the thrust levels required for our reusable Titan medium-lift vehicle targeting 5,000+ kg to LEO while striking the right balance between performance, scalability, heritage, and speed of development to meet the Government of Canada's targets. The Hadfield-10's design will also form the foundation of our SHARP Sabre hypersonic rocket's M2S-HyRock engine. The full shift to the Hadfield-100 is a major milestone for us, and it's not just about more powerful engines. The infrastructure we're developing from moving to a much larger facility, acquiring much larger metal 3D printers, developing new test cells, and pursuing rigorous standards all feed in to this next phase of growth for our program. To everyone on the NordSpace team who designed, printed, tested, and refined these engines across so many late nights, early mornings and weekends, thank you. This chapter made everything that follows possible, and the next one starts now.

A ton of historic firsts last week. Our Relativity Space team proved more in this first launch than most companies (and even countries) ever have in their maiden attempt: ✅ first methane fueled rocket in the West to reach space, well over the 100km Karman Line (only other is China) ✅ first nearly entirely 3D printed rocket to fly and prove 3D printing is viable by passing Max-Q, the max stress on the rocket ✅ first methane orbital-class rocket to successfully complete stage 1 flight, main engine cutoff, and second stage separation in the West (only other is China) ✅ first-ever second stage ignition attempt during the vacuum of flight for a methane fueled orbital rocket in the West, collected first-ever flight data ✅ continuing data reviews, and will bring learnings to our future rocket including Terran R ✅ one really ecstatic launch viewing experience - here, as close as one can get to the launch pad. INTENSE 12 of 10, the reaction makes perfect sense when being there, surreal 🤯
