Thank you Aviation Week for the award in recognition of our full-scale precooler testing with the @prattandwhitney F100 engine! These tests were a major propulsion milestone for our next aircraft, Quarterhorse Mk 2, and pave the way for our full-range, air-breathing hypersonic engine which combines a turbine with a ramjet.

Another day, another Zenith engine hot fire... Here we conduct a chirp test of our thrust vector control system - gimbaling the engine at increasing frequency to demonstrate control bandwidth (how fast we can respond to commands in flight). 📈

10 years. +10,000 engines delivered. +100 million flight hours. A decade ago, the #CFMLEAP engine entered commercial service. 10 years later, reaching these milestones is a testament to the journey we’re building together with our 150+ airline customers and airframers. Maturing a new engine program at this scale comes with continuous effort. Every hour logged and every engine delivered represents the daily hard work of our teams Safran and GE Aerospace, working hand-in-hand with operators worldwide to support their fleets and improve reliability every day. Thank you to our customers and partners for their trust and collaboration as we keep working to support the fleet. ✈️

Our first test flight is just the beginning! Behind the scenes, we are focused on up-scaling and improving our technology. We are excited to announce that we have successfully tested the central subsystem of our Helix 2.0 oxygen-rich staged-combustion engine: the powerpack. We have performed two successful hot-fire tests in which we have shown steady-state operation and cavitation limits. The powerpack incorporates the turbopump and pre-burner(s). It is the most complex as well as the most mechanically and thermally stressed subsystem of a staged-combustion engine. This milestone validated key technological challenges, such as the simultaneous ignition of multiple pre-burners and turbopump cavitation performance. The results are in-line with the predictions from our design models. The closed-cycle architecture of Helix allows us to push the performance envelope further: Helix 2.0 is designed to deliver double the thrust (200kN), while mass, production technology and costs remain comparable to Helix 1.0. The result for our customers: more payload for a lower budget! Excited about this news? Check out our career portal for employment opportunities and help us to elevate our Helix staged-combustion engine technology to the next level! ➡️

Stage 2 testing is officially underway at NASA Stennis 🚀 The campaign kicked off with successful cryoproof, loading the stage with cryogenic fluids and pressurizing it beyond expected flight loads to validate its structural integrity, followed by COPV manifold proof testing to verify the high-pressure system that will pressurize propellants during flight. These tests also marked the activation of A2, bringing together the infrastructure, flight hardware, ground and vehicle software, and the integrated team of test, launch, and vehicle engineers. Next up: hot fire capable assembly work, then back to the stand ahead of stage hot fire testing. 🔥

The NTSB released the security camera video showing the engine separating from the UPS MD-11 moments before it crashed. The docket also includes the inspection of the engines and in particular, engine two which showed a few performance blips prior to the crash but with recovery to commanded speeds. So, I don't believe there's evidence that debris were ingested into engine 2, instead the performance problems were related to the flames from the wing entering engine 2. Some of the footage appears to support this.

BMW M5, E60. This is what made it special. The engine. V10 in a family saloon, what was BMW thinking or snorting back then? 500 hp from the S85B50 V10 engine, high revving and one of the best sounding V10's ever and the best sounding BMW of all time. Nothing else matters as much. Of course, there are downsides. Reliability isn’t great. This is not a simple car to own. But that’s part of it, high risk, high reward. You take care of it, and it gives you that V10 sound. Some even converted them to manual to ditch the SMG gearbox and USA even got the manual from factory. And there’s a Touring as well, even more added insanity.

Our community hasn't just been stress testing Devnet -> they've been finding bugs, flagging edge cases, and making real contributions to the Percolator risk engine. That feedback loop is why we ship better. And while all of this is happening -> we've been quietly testing Mainnet flows. Toly built the Percolator risk engine. We're building the infrastructure on Solana that brings it to life. First look at the Mainnet trade UI 👇

GE9X Water Ingestion Test - Proving the World's Largest Jet Engine Can Survive Extreme Rain The General Electric GE9X, built for the Boeing 777X, must pass brutal certification tests before entering service. One of the toughest is the water ingestion test. What Is the Water Ingestion Test? This test checks if the engine can continue operating safely during extremely heavy rain. During the test: Large amounts of water are sprayed directly into the engine intake The engine runs at high power Engineers monitor performance and stability How the Test Is Performed In a specialized test facility: Water nozzles simulate intense rainfall Thousands of liters of water are injected into the airflow The engine operates at different thrust levels Sensors monitor: Combustion stability Compressor performance Temperature and pressure changes What Engineers Are Checking The engine must prove that: No flameout occurs No compressor stall happens Thrust remains stable Internal components are not damaged Even with massive water flow, the engine must keep running smoothly.

You thought the sky was the limit? Wingbits is going to space 🚀 thanks to a strategic partnership with Spire, leader in space-based data and operator of the largest multipurpose satellite constellation. 🛰️ Together we’re launching a new satellite that will act as a validator of Wingbits’ ground data, increasing the security and reliability of our global flight tracking network. The satellite is scheduled for launch on the SpaceX Transporter-13 mission.

Great news from our team to start the week: positive Phase 2 results for a potential first-in-class medicine discovered and developed entirely in-house at Pfizer Inc.. It has the potential to work differently from anything available today, targeting three drivers of inflammation in a single treatment. This could make a real difference for millions of people living with conditions like atopic dermatitis, COPD, and asthma. We're accelerating toward Phase 3 and excited about what lies ahead. This is the kind of innovation our pipeline is built to deliver. More:
