The SHOCKING Reason Why Single Propeller Engines Aren't Straight! Ever noticed that the engine on some small planes looks slightly crooked? It's not a design flaw - it's pure aerodynamic genius! Propeller engines are intentionally mounted at an angle (a trick called engine offset) to counteract something called P-factor...

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.

How Powerful Are Jet Engines? A modern commercial jet engine can generate 200-500 kN (45,000-110,000 lbf) of thrust, allowing aircraft carrying hundreds of passengers to take off safely. Military fighter jet engines are built for extreme performance. A single engine can produce 70-190 kN (15,700-43,000 lbf) of thrust, while advanced afterburners dramatically increase power for supersonic flight, rapid acceleration, and high-speed combat maneuvers. Jet engines don't create "horsepower" like car engines-they produce thrust, the force that pushes an aircraft through the sky. Their incredible engineering makes modern aviation possible.

Gnome Omega (1909) - The Engine That Spun Aviation Forward In 1909, the Gnome Omega became the first mass-produced rotary engine, marking a major breakthrough in early aviation. At a time when aircraft struggled with heavy, unreliable, and overheating engines, Gnome introduced a radical solution: instead of the crankshaft turning, the entire engine-cylinders and all-rotated around a fixed crankshaft. This spinning design dramatically improved air cooling, eliminating the need for complex radiators, while also delivering an excellent power-to-weight ratio-a critical advantage for the fragile aircraft of the era. The Omega quickly powered some of the most important pioneers of flight, including aircraft used by Louis Blériot during the early days of aviation, helping push the limits of what was possible in the sky. Rotary engines would eventually be replaced by more efficient inline and radial designs, but for a crucial moment in history, they were the cutting edge of flight technology.

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.

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

Redundancy isn’t a backup plan. It’s the plan. During our Q1’25 operating and financial results call, Archer CTO, Tom Muniz, referenced this flight test from last year—Midnight flying smoothly with an engine out. With 12 electric motors, Midnight is designed to handle the unexpected. As detailed by Tom, this is a powerful demonstration of the “safety-by-design” approach that is core to our aircraft. Watch the test flight. See the benefits of our proprietary 12 tilt 6 design in action.

#WATCH | Air India Plane Crash | Noida, UP: Former Pilot Ehsan Khalid says, "... The Flight Data Recorder, Cockpit Voice Recorder and the ACARS data will tell exactly what may have happened. The visuals show that the aircraft went down while flying. Which means there was no mid-air explosion... The visuals show that the aircraft faced a loss of power... The loss of power can be due to engine malfunction, but it is very unlikely that both engines would lose power simultaneously... It is a very big engine, and it is rare that both engines lose power due to a bird hit in a one-minute duration... The pilot gave a mayday call. This means that the failure was seen in the cockpit... They went airborne while combating that failure... I don't understand why the landing gear was still down... The landing gear is raised as soon as the flight takes off... Since the landing gear was down, it is possible that a loss of engine was detected beforehand... There are many variables, and any speculation would be unjust... The biggest question is why the landing gear was not up. The flight was at a height of 600 feet... Whether it was one problem or multiple problems, no one can say anything yet..."

🚨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

.Bob Allen practicing a V1 cut in our Westwind II today. There’s only one 1124 sim in the world - so we do our training in the actual plane! A V1 cut is an engine failure after V1 (takeoff decision speed). It means we’re past the point where a rejected takeoff is safe or possible, therefore we must take-off on the remaining good engine. All pilots practice V1 cuts on large multiengine aircraft, but usually in a simulator. We do it as part of every recurrent Checkride on the big jets, but it’s extra trippy doing it for real! That said, the “failure” is really just one engine being pulled back to idle thrust, so it’s available IF necessary. Notice - it’s barely even an event in the hands of a skilled professional pilot. Rudder is applied to the side of the good engine, directional control is maintained, and the aircraft is rotated into a climb at V2 while the non-flying pilot retracts the gear and the flaps. The “issue” and subsequent troubleshooting/shutdown procedures are delayed until the aircraft is at a safe altitude.

49 years ago today: America´s worst air disaster May 25 1979: American Airlines Flight 191, a DC-10, crashes on takeoff from O'Hare (Chicago, US). All 271 aboard plus 2 on the ground die, the deadliest airliner crash in US, a figure only surpassed by the 9/11 terrorist attacks. On take-off, the engine separated from the wing due to improper maintenance, damaging hydraulics, and causing loss of control, as detailed below. Specifically, it was determined that during takeoff rotation, the No. 1 (left) engine separated from the left wing, flipped over the wing, and landed on the runway. The separation severed the hydraulic lines that lock the leading-edge slats in place and damaged a 3-foot (1 m) section of the left wing’s leading edge. Aerodynamic forces then caused an uncommanded retraction of the outboard slats. As the aircraft climbed, the damaged left wing generated substantially less lift than the right wing, whose slats remained deployed, and the engine provided full takeoff thrust. The resulting aerodynamic imbalance produced an abrupt left roll to a 112° bank angle—partially inverted—before the aircraft crashed in an open field adjacent to a trailer park near the runway’s end. The engine separation was caused by structural damage to the pylon, resulting from improper maintenance procedures at American Airlines, which are detailed in the thread below 1/6 ⬇️ 🧵 Video – Plane N´ Boom (animation from Mayday ACI series)

A car owner used to service his own car to save money on service costs. After some time, his car’s engine started overheating again and again. Even after driving the car a short distance, the engine would become extremely hot and problems started developing in the engine, even though he was also putting coolant in his car. When the engine finally got damaged, he took his car to a mechanic. When the mechanic checked the car, he found that the owner had filled the engine coolant into the wrong tank instead of the coolant tank. He had filled it into the tank where the water for cleaning the car’s front windshield is kept. Then, when he turned on the wipers, all the coolant was sprayed onto the car’s front windshield through the pressure of the water motor. This was the reason his car kept overheating and the engine got damaged, because the coolant had been sitting in the windshield-washer tank instead of the coolant tank. When the mechanic checked the engine, he found that it had been completely damaged due to repeatedly overheating. Now, the car owner will have to spend a huge amount of money to get the engine repaired. The car owner wanted to save a little money by servicing his car himself, but because of that, he ended up damaging the entire engine of his car. That is why you should never do something without knowledge. You should not try to become an expert at everything you have never done before, because it can lead to a huge loss.

Cathay Pacific A330 aborts its takeoff in Kaohsiung after a loud bang and what appeared to be flames from one of the aircraft’s engines. A video posted on Facebook of the incident shows the airplane suddenly decelerate after a bang is heard and a flash of flame is seen coming out of one of its engines. The aircraft veers off course slightly before correcting and safely taxiing back to the terminal. A Cathay Pacific spokesperson said CX431 was aborted “due to an engine technical problem”. The spokesperson apologized for the inconvenience that may have been caused by the incident, and said safety is a priority for the airline.

Humbled to announce the successful firing of our single piece Agnite engine. Agnite engines power Agnibaan’s booster stage. These engine chambers are a full meter long, fully 3d printed as a single piece of hardware and made of Inconel. Agnite engines are driven by pumps that are controlled and operated by electric motors. Thanks to ISRO & IN-SPACe for their constant support and to IIT Madras for being our home turf from which this kind of technology is built. This Agnite engine was printed, depowdered and post processed in the same machines that we inaugurated as a part of our Large Format Additive Metal Manufacturing facility (LFAMM) towards the end of last year. This milestone is also significant for us because it completes one end-to-end cycle of design, manufacturing, assembly and testing of our larger engines, in-house. Amazing work by the team in pulling off a few world firsts here. - world’s first single piece engine of this size being fired - world’s largest inconel only engine - world’s only electric motor fed, semi cryo engine of this size and the list continues. However, this is not a race to be the world's first, it is a race to be the world's best & to be the world's most useful technology for launching small satellites to orbit. This comes right after firing a cluster of 3 semi cryogenic engines that happened last month. Honoured to be working with a team that truly believes in building world class, original space technology for the world, from India.

Amazing work by the team in pulling off a few world firsts here. - world’s first single piece engine of this size being fired - world’s largest inconel only engine - world’s only electric motor fed, semi cryo engine of this size and the list continues. However, this is not a race to be the world's first, it is a race to be the world's best & to be the world's most useful technology for launching small satellites to orbit. This comes right after firing a cluster of 3 semi cryogenic engines that happened last month. Honoured to be working with a team that truly believes in building world class, original space technology for the world, from India.

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.

‼️🇺🇸Meet the Aircraft That Transforms From Helicopter to Airplane The Bell Boeing V 22 Osprey is one of the most unusual aircraft ever built. It lifts off vertically like a large helicopter, rising straight from the ground without a runway. Then its powerful rotors rotate forward, transforming the aircraft into a fast flying plane. This unique design allows it to combine the vertical takeoff ability of a helicopter with the speed and range of an airplane. That is what makes the V 22 Osprey so valuable for long distance missions where normal helicopters would struggle. One aircraft. Two flight styles. Helicopter when it takes off. Airplane when it flies.

Another ill-fated take-off over V1 (in this case, V2!) June 13 1996: Garuda Indonesia Flight 865, a DC-10, crashes in Fukuoka (Japan) 3 of 275 aboard die. On take-off, the jet had just left the ground when one of the engines failed. Crew opted to reject the maneuver; the aircraft was unable to stop safely and left the runway: landing gear collapsed, and the airplane caught fire. Inquiry noted pilot actions by aborting takeoff above V1, where SOP dictated pilots should have continued takeoff and deal with the engine later. More info below from Aviation Safety Network – Aftermath video is from Aircrashdaily (go give them a follow on YouTube) “The DC-10 accelerated for takeoff. The nose was raised, and at a speed of 158 kts, the first officer called "Rotate". It was 12:07:40. Three seconds later, at a radio altitude of 9 feet, a fan blade of the 1st stage HP turbine from the no. 3 engine separated. The N1 dropped to 23,7% within a few seconds. At 12:07:45, the flight engineer called "Engine failure number one." Takeoff was aborted at about the V2 speed, and the airplane contacted the runway one second later at a vertical acceleration force of 2.1 Gs. The thrust reversers were deployed and ground spoilers were extended. The DC-10 skidded off the runway through a ditch, fence and a road, before coming to a halt 620 m past the runway threshold. Investigation revealed that the turbine blade that failed, had operated for 30913 hours and 6182 cycles. General Electric had advised customers to discard blades after about 6000 cycles. Accident cause Although the Aircraft was well in excess of V1 and the aircraft had already lifted off from the runway, the takeoff was aborted. Consequently, the aircraft departed the end of the runway, came to rest and caught fire. It is estimated that contributing to the rejection of the takeoff under this circumstance was the fact that the CAP's judgement in the event of the engine failure was inadequate."

This guy stands right there on the edge of the runway in his white cap, phone raised to capture every second, as the colossal gray U.S. Air Force cargo plane fires up its four massive engines with a thunderous growl right beside a tiny white propeller plane that suddenly looks like a toy next to it. The ground seems to tremble while the giant slowly taxis into position, then unleashes its full power—accelerating hard down the long stretch of pavement, tires biting in and kicking up swirling clouds of dust and smoke. In one heart-stopping instant the enormous aircraft lifts its nose, landing gear still down, and climbs powerfully into the overcast sky with pure, majestic grace. What an incredible display of raw power and human ingenuity that reminds us how thrilling it is to watch something so massive soar with such effortless beauty. Have you ever stood this close to a giant plane taking off and felt that rush of pure awe?
