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

There’s a new rocket engine on the block 👀🚀 Astrobotic just announced that its newly developed “Chakram” Rotating Detonation Rocket Engine successfully completed its first test campaign. RDREs have long been theorized as a highly efficient form of propulsion, but only in the last five years or so have they started becoming reality. They work by sustaining supersonic rotating detonation waves inside the engine, helping improve efficiency across a range of operating pressures. Chakram produced more than 4,000 pounds of thrust and fired for 300 seconds during testing. Astrobotic

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

Hyundai Rotem has released a video introducing the LRAAM missile. It is currently being jointly developed with LIG Nex1. The integrated ducted ramjet propulsion is shown briefly. ●The difference from the initially revealed LRAAM is the addition of strakes. ●Since South Korea's numerous air-launched strike missile programs are considered first and the existence of the MBDA Meteor, the development period is generous and is scheduled to end in 2032. ●The consortium is competing with Hanwha Aerospace. ●The SRAAM short-range air-to-air missile is being developed by LIG Nex1. ●The solid fuel gas generator generates fuel-rich gas through primary combustion. Air entering through the air intake is mixed with the fuel-rich gas and then combusted a second time in the combustor to generate thrust. ●Ducted ramjet or ducted rocket propulsion systems simplify the fuel supply system and are lighter than liquid-fuel ramjet propulsion systems. Liquid-fueled ramjets offer better fuel efficiency and fuel supply control. However, they require additional fuel handling and are more expensive and heavier. ●As part of the recent success of its ground-launched hypersonic cruise vehicle, Hyundai Rotem also released CG of an air-launched hypersonic anti-ship cruise missile. The disclosed information mentions the use of hypersonic cruise missiles on land, sea, and air, and Hyundai Rotem is considered to be leading the way in cutting-edge engine and materials technology. ADD and Hanwha Aerospace are also participating in this sensitive program.

🚨🇨🇳 WEST IN PANIC: CHINA JOINS ELITE CLUB IN ADVANCED TURBINE BLADE TECHNOLOGY If the aero-engine is the pearl of modern industry, the single-crystal turbine blade is the diamond atop it. China has now mastered the complete technology chain — from materials, Research and Development, and precision casting to full engineering application — joining just 5 nations total: US, UK, Russia, France, and now China. 🔸 China’s DD6 single-crystal superalloy features 100% domestic IP and matches or exceeds 2nd-generation Western alloys while delivering significantly lower production costs. 🔸 These blades now power advanced fighter jets, helicopters, and civil aircraft, providing higher thrust, lower fuel consumption, and superior performance under extreme temperatures and pressure. 🔸 The full manufacturing chain spans over 10 major core processes — each with dozens of precise sub-steps — all now fully indigenous after closing decades of technological gaps. 🔸 This breakthrough saves China massive strategic resources and establishes new benchmarks for engine reliability and service life. Do you think the West can stop China's technological progress?

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 #missiles #hypersonic #HypersonicMissile #Scramjet

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.
