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

The General Electric GE90 is one of thr most powerful jet engines ever built. Powering aircrafts like the Boeing 777. During start up, compressed air spins the massive fan and internal compressor stage, gradually bringing the engine to life before the fuel is introduced and ignition occurs.

The Boeing 777 was the first Boeing commercial airliner to feature a full digital fly-by-wire (FBW) flight control system. Powering this 777-300ER are the GE90 engines—the world's most powerful commercial jet engines. Each engine has a fan diameter so large that it is wider than the fuselage of a Boeing 737. After engine start, the hydraulic systems come to life, and the flight crew performs the flight control surfaces check. You can see the rudder, elevators, slats, and flaps moving before being configured for takeoff. Once both engines are running and supplying electrical and pneumatic power, the APU is shut down, causing the APU air intake door to close. B777-300ER (5Y-KZX) KQ100 Nairobi to London 8½ hrs.

Inside Pratt & Whitney PT6A-67B engine, two turbine systems spin in opposite directions at tens of thousands of rpm, yet they aren't mechanically connected at all. The gas generator spool reaches roughly 37,500 rpm. Its hot gas drives an independent power turbine at nearly 30,000 rpm, producing up to 1,200 shp. Then there is the gearbox. A compact two stage reduction system has to take that 30,000 rpm input and drop it all the way down to just 1,700 rpm at the propeller, while transmitting roughly 5,000 Nm of torque reliably, flight after flight under all kinds of loads and conditions. All of this happens inside an engines that weighs only about 235 kgs, with interstage turbine temperatures reaching roughly 800°C during takeoff. That combination of extreme speeds, temperatures and mechanical simplicity helped make the PT6 one of the most successful turboprop engines ever built. More than 64,000+ engines have been built and they have accumulated more than 500 million flight hours so far. Whether it is a jet engine or almost any other machine, the really successful designs tend to have one thing in common, the materials, mechanics and overall design work together so well that something incredibly complex ends up looking almost simple.

This is not a model engine pretending to be a jet engine. It is actually a complete gas turbine shrunk onto a test bench. Inside this small machine are a compressor, combustion chamber, turbine wheel, fuel system and digital engine controller, the same basic physics used in aircraft engines. At full power, this turbine reaches nearly 98,000 RPM over 1,600 revolutions every second while producing 280 N of thrust, equivalent to roughly 28 kg of pushing force. At nearly 98,000 RPM, even a tiny imbalance can destroy the turbine. The combustion chamber must survive exhaust temperatures approaching 700°C, while the fuel system continuously manages a core flame powerful enough to create 280 N of thrust without losing combustion stability. A high-end RC turbine can cost $7,000-20,000+, despite fitting on a workbench. It is nowhere near the complexity of a modern military turbofan with thousands of components, afterburners and advanced cooling systems. But that is what makes it fascinating, engineers have compressed the core mechanisms of a jet engine compression, combustion and expansion, into a machine small enough to hold. 📹 RC hobby

🚨People watching this think it looks fake… It isn’t. That is a real F-22 Raptor performing an unrestricted climb. This maneuver is something only a handful of aircraft on Earth can do. When the pilot rotates and goes straight up like that, the aircraft is converting pure engine thrust into vertical climb. The reason it can do it comes down to the engines. The F-22 is powered by two Pratt & Whitney F119-PW-100 turbofan engines. Each engine produces about 35,000 pounds of thrust with afterburner. Combined thrust: About 70,000 pounds. Now compare that to the aircraft’s weight. Typical combat weight: ≈ 64,000 pounds That means the Raptor has a thrust-to-weight ratio greater than 1:1. In simple terms… The engines produce more thrust than the aircraft weighs. That allows the jet to accelerate vertically. And it gets even crazier. The engines use two-dimensional thrust-vectoring nozzles, allowing the exhaust to tilt up and down to maintain control even when airflow over the wings is minimal. Top speed ≈ Mach 2.25 (about 1,700 mph) Supercruise ≈ Mach 1.5 without afterburners Service ceiling ≈ 65,000 feet Only about 183 operational F-22s were ever built. Which means when you see a Raptor do this climb… You’re watching one of the most advanced air-dominance fighters ever created. #SilentMajoritySpeaks #AStoneGroove

MIG31 Engines The MiG-31 was a monster in its era. The two Soloviev D-30F6 reached around 3,000 km/h (Mach 2.83). No other aircraft came close in terms of power. It was far superior to everything that existed at the time, such as the F-14 Tomcat and F-15 Eagle, and compared to the Tornado it had roughly double the thrust. Only with the arrival of the F-22 did the West finally field something slightly superior to the MiG. Even when compared to modern fighters today, this beast still demonstrates its power, with roughly double the thrust of the Rafale and nearly 40% more than the F/A-18.

Following the Delta A330-323(N813NW) engine failure after departure from São Paulo (GRU), many are asking: what actually happens if an airliner loses an engine just after takeoff? As passenger in the cabin watching this scenario unfold, the panic is understandable. Seeing flames from an engine is alarming. But this is exactly the kind of scenario pilots are trained for repeatedly in simulators. Modern multi-engine aircraft are designed to fly safely on one engine. In fact, losing one engine is a certification requirement during testing. Here’s what happens: At liftoff, pilots target V2 speed—the minimum safe speed that guarantees the aircraft can continue climbing even with one engine inoperative. If an engine fails: • The MASTER FIRE warning light will illuminate in the cockpit and the fire warning bell will sound, alerting the pilots on the affected engine (they will close the fuel, hydraulic shutoff, and engine bleed air valves, and also discharge the related fire bottle to extinguish the engine fire). Of course, they will be careful NOT TO shut down the wrong engine (this has happened before). • Maximum thrust is applied on the remaining engine. • Rudder input keeps the aircraft straight (countering asymmetric thrust) • The aircraft climbs straight ahead for best performance (turns reduce climb rate unless required) Once above a safe altitude (typically ~1,500 ft / Minimum Flap Retraction Altitude(MFRA): • The aircraft accelerates • Flaps are retracted (“cleaning up”) • Crew assesses the situation and plans a return or diversion Even at very low altitude, the aircraft remains controllable by design. It may not climb aggressively, but it will climb. Bottom line: What looks catastrophic from the cabin is a scenario pilots are highly trained to handle—and aircraft are engineered to withstand. Hope this helps any nervous flyer. Flying is safe, and the chances of this happening have reduced due to lessons learned from previous incidents. And if you ever find yourself in this situation, trust that the pilots will act according to their training—because that’s their job.

This is one of the most punishing certification tests any airliner must survive Rejected Takeoff (RTO) For certification, Boeing accelerates the jet to just below V1 at around 775,000 lb (351 tons), then cuts thrust and applies maximum braking. The airplane has seconds to go from full power to a complete stop.

🧐🇺🇸🇸🇪 No American Engine, No Gripen. Sweden's Gripen is widely regarded as one of Europe's most capable fighter jets. But here's a fact many people don't know: Every Gripen ever built has flown with American engine technology. From the RM12, derived from the U.S. General Electric F404, to the latest Gripen E powered by the General Electric F414G, the jet's thrust has always come from the United States. Sweden built the aircraft. America powers it. It's a reminder that designing a fighter jet is difficult. Building a world class jet engine is even harder. Even one of Europe's most advanced fighters depends on U.S. aerospace engineering to leave the runway. The Gripen wears Swedish colors. Its heartbeat is American.

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.

India is pushing ahead with the next generation of its indigenous fighter engine programme—Kaveri 2.0. Developed from the experience gained through the original Kaveri engine, the new programme aims to overcome the challenges that previously prevented India from using Kaveri to power the Tejas fighter. The bigger goal is strategic: develop a powerful indigenous turbofan that can eventually support India’s future combat aircraft, including the AMCA. A successful Kaveri 2.0 could give India greater control over critical engine technology, reduce dependence on foreign suppliers and strengthen its ability to design and build advanced fighter aircraft. But developing a modern fighter engine is one of the most difficult challenges in aerospace engineering. From high-temperature turbine technology and materials to combustion, efficiency and reliability, Kaveri 2.0 will have to clear several major technological hurdles before it can become an operational fighter engine. #kaveri #KaveriEngine #amca #tejas #FighterJet

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

Raptor 3 is really kind of an alien technology rocket engine. Even industry experts, when we showed a picture of the Raptor 3, said, that engine is not complete. Then we said, here's the engine, not complete, firing at a level of efficiency that has never been achieved before. That is one clean engine. In order to make the engine like that, we had to simplify so many parts of the design, incorporate secondary fluid circuits and electronics in the structure of the engine itself so everything is contained and protected. It is a marvel of engineering, frankly.” From: SpaceX Update, May 27, 2025

One of the most extreme piston engines ever built is the Pratt & Whitney R4360 Wasp Major. A 28 cylinder, four row radial engine producing 3,000 Hp in early variants and over 4,000+ Hp in later iterations from 71 liters of displacement. R-4360 Wasp burnt 25.5-26.5 liters per minute per engine at takeoff It was developed during World War II for long range heavy bombers, but by the time it reached full operational maturity, the war had already ended. Instead of CAD or computational simulation, it was designed entirely using slide rules, hand drafted blueprints, and physical prototyping, where every thermal and structural constraint was solved experimentally. This Engine costed $35,000 - $50,000 per engine back in 1944-45 USD. This engine marks the final peak of piston propulsion, built at the edge of manufacturable complexity before the jet age made it obsolete. Video Source :- MaxwellDebun

For today's maintenance reel: a little moment with the Boeing 777-300ER and the mighty GE90. Biggest commercial engine out there and yes, you actually need a platform truck just to reach the oil tank. Once you're up there, it's honestly just another engine servicing, nothing dramatic. No sight glass to help you out and it takes its sweet time sipping oil, but you eventually get it done. And that smoke in the video? That's just the mix of body heat meeting Canadian cold. Classic winter apron life. Enjoy this quick look at GE90 oil servicing in the wild. 📸 by ig/only_fancowl . Go follow him for more ✈️

The name on one of the crew might ring a bell... June 19 1947: Pan Am Flight 121, a Constellation, crash-lands in Mayadine (Syria). 14 of 36 aboard die. In flight, the #1 engine failed due to a mechanical issue. Attempting to divert to an alternate airport, the #2 engine also failed. The crew made a belly landing in the desert, where the aircraft caught fire. Among the survivors was a dead heading 3rd officer named Gene Roddenberry, who would go on to create the iconic science fiction television series “Star Trek”. This was Roddenbery´s 2nd major plane crash, having survived another major accident during his service in the Pacific Theatre, during WW2 Accident description from ASN (One of many period accidents where an engine failure led to a fatal crash. Nowadays, an engine fail is nearly routine and at worst it causes a diversion...) "The Constellation, named "Clipper Eclipse", was cruising at FL185 when the no. 1 prop had to be feathered due to engine problems. The remaining three engines overheated, forcing the crew to reduced power. This resulted in a gradual descent. The crew elected to continue to Istanbul instead of landing at the nearby Habbaniya RAF Station in Iraq. While descending through FL100 a fire broke out in the engine no. 2 nacelle. A rapid descent was started during which the no. 2 engine separated from the wing. With the left wing on fire a belly landing was carried out in the desert. It appeared the no. 1 engine failure was due to a broken exhaust rocker arm on the no.18 cylinder. The no. 2 engine failure was due to a failure of the thrust bearing which in turn resulted in blocking the passage of oil from the propeller feathering motor to the propeller dome. PROBABLE CAUSE: "The Board determines that the probable cause of this accident was a fire which resulted from an attempt to feather the No. 2 propeller after the failure of the No. 2 engine thrust bearing."

This was Roddenbery´s 2nd major plane crash, having survived another major accident during his service in the Pacific Theatre, during WW2 Accident description from ASN (One of many period accidents where an engine failure led to a fatal crash. Nowadays, an engine fail is nearly routine and at worst it causes a diversion...) "The Constellation, named "Clipper Eclipse", was cruising at FL185 when the no. 1 prop had to be feathered due to engine problems. The remaining three engines overheated, forcing the crew to reduced power. This resulted in a gradual descent. The crew elected to continue to Istanbul instead of landing at the nearby Habbaniya RAF Station in Iraq. While descending through FL100 a fire broke out in the engine no. 2 nacelle. A rapid descent was started during which the no. 2 engine separated from the wing. With the left wing on fire a belly landing was carried out in the desert. It appeared the no. 1 engine failure was due to a broken exhaust rocker arm on the no.18 cylinder. The no. 2 engine failure was due to a failure of the thrust bearing which in turn resulted in blocking the passage of oil from the propeller feathering motor to the propeller dome. PROBABLE CAUSE: "The Board determines that the probable cause of this accident was a fire which resulted from an attempt to feather the No. 2 propeller after the failure of the No. 2 engine thrust bearing."

⚡️‼️🇷🇺The Russian side has effectively confirmed for the first time that the "Orion" (also known as "Inokhodets") drone is a carrier for the small-sized cruise missile "Banderol." Ukraine designates this missile as S-8000. According to reports, the munition is capable of hitting targets at a maximum range of up to 500 km. The "Banderol's" cruising speed is 520–560 km/h, with a maximum speed of up to 650 km/h. The warhead weighs approximately 114–150 kg (with a net explosive weight of around 50 kg). It appears that the "Orion" is capable of carrying only one such missile. The most interesting aspect is the model and manufacturer of the jet engine. For a long time, a Chinese commercial engine, the Swiwin SW800Pro, was used on these missiles.
