@NASAStennis You're using a near-stoichiometric propellant ratio?

@NASAStennis > but it also serves as undeniable proof of the 99%+ combustion efficiency achieved in this test. Because there are few to no little-bitty carbon bits left over to glow orange? Is that it?

@NASAStennis Wow, that’s a good lookin’ plume

@UCS_Mark @fakecarlsagan @Mayo_Mingzi @launcher @NASAStennis Oxygen rich staged combustion just means that the preburner and turbines are running oxygen rich. The main combustion chambers are always slightly fuel rich, which actually benefits ISP due to lower molecular mass of combustion products vs stoichiometric or ox-rich combustion.

@NASAStennis The plume is great, but I always like the shots inside the nozzle itself. It looks shiny!

@NASAStennis What kind of injector is E-2 using?

Noah Psiharis 🇨🇦2 years ago

@JaxLR07 @NASAStennis Woow 😍😍 blue flame for the win.

@NASAStennis What was the temperature under the sustained load? Also, were there other interesting results recorded during the test?

dotty2 years ago

@NASAStennis Nice example of stoichiometric combustion , maybe efficient but thrust and ISP depends on the combustion products as well

E-2’s first 90-second test fire was a success! It performed at 55% power with a low conservative 1.6 mixture ratio as planned. The hardware appears in perfect condition ready for more tests. This is an exceptional result for a first test article (E-2 SN1). The test was also a key milestone for our US Space Force TACFI contract. We’ve wrapped up this test campaign and will be back in January with an updated injector featuring lower LOX passage pressure drop to allow us to increase the LOX mass flow and in turn reach full thrust and high performance O/F mixture ratio of 2.62. We thank our team and partners for making this possible - especially Stennis Space Center and their team. We would also like to thank the @SpaceForceDoD for their TACFI contract support.

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.

January’s GS2 performed remarkably during our inaugural New Glenn launch, delivering our payload to orbit with less than 1% deviation from the target. Today, we completed a full duration 15-second hotfire test of the upper stage for our NG-2 mission. This time, we achieved enhanced performance from the BE-3U engine, increasing the maximum thrust from 173,000 lbf to 175,000 lbf per engine, further expanding New Glenn’s capabilities for our customers.

Good news on the jet engine project ✅: I redesigned the exhaust system again to prioritize cooling, thrust & the afterburner sequence all together, it now works better✅, no red hot situation on the exhaust at all✅ The new design also reduces pressure on the turbine on AB mode✅ This test was done with gas for the main engine running at 50% power, then liquid kerosene for the AB🔥. I wish to change the fuel nozzles on the main burner to a more powerful one next week, then we'll do this test again close to 100% power which will be louder & much more violent ⚡️ After that, we'll go straight to a runway & let this beast run🚀 #Zedora #madeinEbonyi 🇳🇬

This was just a brief test as it was already late. Huge improvement on engine power. Don't forget, this prototype is actually big; With an 8ft wingspan and weighing about 60kg, this is no toy⚠️ There's no space in this compound anymore for this project It is now too loud, too fast & too powerful for this place (I don't want my neighbors to make me a topic at the next estate meeting🥲) Also don't forget, every time we do a full test, the engine burns about ₦30k worth of kerosene ⚠️ R&D is no small thing This is the update on our indigenous aerospace project development. Work on the control computer system & further testing continues #Zedora #madeinNigeria 🇳🇬

This rocket is eating itself! Currently, most of the mass of space rockets is fuel. But what if we used not just... well, fuel... but also the rocket body itself as fuel? That's exactly what you're seeing now. In addition to burning liquid fuel inside the test rocket, the rocket's walls, made of a special plastic, are also burned, effectively adding a little more fuel. The idea itself isn't new, but the key is that in this case, researchers from the University of Glasgow managed to create a setup in which the body would remain stable, rather than warping, during combustion.

Advancing LOX/LCH4 Dual-Propellant Cooling for HANBIT-Micro INNOSPACE has successfully completed a series of combustion tests for its upgraded 4 kN-class liquid-methane kick-stage combustor for HANBIT-Micro. 🚀 Building on the 237-second long-duration ground test in May 2024, the combustor has been advanced with a Dual-Propellant Regenerative Cooling scheme. 📈 ⚙️ Unlike conventional single-propellant regenerative cooling, this approach utilizes both fuel and oxidizer as coolants, enabling: 🔹 Reduced feed pressure requirements 🔹 Lighter propellant tanks 🔹 Lower overall kick-stage mass 🔥 By preheating and vaporizing both coolants, the system also achieves: 🔹 Improved mixing efficiency 🔹 Shorter ignition delay 🔹 Enhanced combustion stability and efficiency 💡 Overcoming High Technical Barriers Most notably, the recent test validated stable regenerative cooling under low-pressure, subcritical conditions — a technically demanding regime — and mitigated the risks associated with using liquid oxygen (LOX) as a coolant. The application of a gas–gas swirl injector further demonstrated improved mixing performance. With this milestone, INNOSPACE continues to advance methane propulsion technology and enhance the maturity of the HANBIT-Micro kick-stage system. Please stay tuned for the next phase of development. 🙌 #SpaceInnovation #HANBITMicro #KickStage #MethaneEngine #RocketEngineering #SpaceTech

STARSHIP V3 SHIP 39: THE REUSE AUDITION BEGINS Everyone watches launches. Engineers watch the tests before them. Ship 39 just rolled from Mega Bay 2 to Massey’s test stand – engine bay empty on purpose. The Test Ladder: * Rollout complete – Ship 39 now sitting at Massey’s dedicated test stand * Cryo proof testing – tanks filled with liquid nitrogen to simulate brutal flight conditions * Pressure cycles – checking domes, tank walls, thrust structure and leaks * Structural stress – proving the ship can survive real propellant loads Pass that test and the real fun starts: * Install 6 Raptor 3 engines * Move to Orbital Launch Pad 2 * Full propellant load – liquid oxygen + methane * Static fires – first single engine, then all six This one is different. Ship 39 is the first flight-ready Block 3 Starship – taller, stronger, and built for reuse. If testing holds, it flies with Booster 19 on Flight 12. Target: March 2026. Source: Grok SpaceX

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

Azhar’s Masterclass! #OnThisDay in 1993, Mohammed Azharuddin smashed 182 v England at Eden Gardens, Kolkata. Azhar’s 182 came off just 197 balls (12x4, 1x6). India won the test by 8 wickets. This was Gooch’s 100th test & Venkataraghavan’s first test as umpire. Azhar was made captain for only first 2 ODIs and 1st test against England in 1993. Azhar not only retained his captaincy but also became the first Indian captain to win all 3 Tests of a series.
