In a recent hotfire our BE-3U engine reached more than 211,500 lbf thrust. That makes BE-3U the highest thrust-to-weight hydrogen engine in history, at more than 90! Here is the video of that test for your enjoyment.

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.

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.

#WATCH | Delhi: On Kaveri engine development, DRDO Chairman Samir V Kamat says, "Kaveri engine, in its original form, has not delivered the thrust that is required for the LCA. The engine is working very well, it has given us a thrust of 72 kilonewton. But the LCA needs a thrust of 83-85 kilonewton. So, it's not going to be used in the LCA but we are using the derivative of the Kaveri engine for our unmanned combat aerial vehicle. So, without the after burner, the Kaveri engine will be used in our unmanned combat aircraft..."

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’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.

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:

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

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.

We are back at it with forward module testing, gearing up for New Glenn’s second flight. Part of this testing campaign is to activate the hydrogen peroxide system that fuels our Reaction Control System, or RCS. The GS1 RCS provides 20,000 lbf thrust in any direction, allowing the first stage to reorient itself in space before re-entry and to precisely target Jacklyn in high winds during landing. To give you an idea, a single F-18 Super Hornet F414 engine provides a similar amount of thrust at 22,000 lbf, so you can see how powerful this system is. The RCS performed nominally during our NG-1 flight and successfully reoriented GS1 to within 0.5 deg of our target attitude during exo-atmospheric flight.

🌕 Tested on Earth. Bound for the Moon. The BE-7 engine for our Blue Moon MK1 lunar lander just completed acceptance testing. Two 290-second tests exposed the engine to its full range of thrust and mixture ratios to verify engine performance. The engine is now off to Florida for integration with MK1.
