These airliner engines are awesome. Excellent video! I've stood in about the same place and filmed one of our tests of the LM2500, which is basically a CF-6 without a fan and LP turbine. It is so much quieter and less threatening than this video. Possibly of interest: our LM2500 had a data plate stating its rated power was 34,800 Hp. The CF-6's in your video are undoubtedly newer, and likely making even more power!

The 'white smoke' which is actually water vapor is the product of the engines pulling the air into what is a venturi (basically a narrow passage). In the venturi, to maintain equilibrium the air must either travel faster or the pressure must increase. Due to a not perfect system the result is some of both which causes the intake air to rapidly cool for a short time as it enters the intake. The cooling of the air causes the water vapor to condense which creates 'smoke' or more accurately a cloud.

Due to Divergent construction of engine intake duct, the air hits the leading edge of the intake and then 3 things happen: 1: The velocity of the air is greatly slowed down, 2: Air is pressurized, 3: The Air temperature is increased. All this before the air even hits the engine. Just by the shape of the intake....

It's a Vortex - From Wikipedia - A vortex (plural: vortices) is a spinning, often turbulent, flow of fluid. Any spiral motion with closed streamlines is vortex flow. The motion of the fluid swirling rapidly around a center is called a vortex. The speed and rate of rotation of the fluid are greatest at the center, and decrease progressively with distance from the center. This engine is only demonstrating it's take off procedure. And does no harm whatsoever to the engine

@Wahlsen and @MikeyNCat Actually, the tips of the fan blades not only go transonic, they go supersonic at about 80-90% power. At full power, blades tips can go Mach 1.5. So a lot of the blade actually goes supersonic, not just the tips. Also, destructive shockwaves do not form because of the duct surrounding the fan and the number of fan blades. That only happens with propellers and unducted fans. You can tell when the fan blades go supersonic by the loud growling/buzzing sound they make.

@Jakeyboyshow Exactly. This is the same reason that engines being run when they have a guard on the front (such as say in a test facility) can only be safely run under certain constraints of temperature and humidity. Above a certain humidity, below a certain temperature, this process can cause ice to form on the front of the guard, eventually causing a semi vacuum behind it, and sucking the lot through the engine. Big, expensive bang.

The air pressure at the inlet of the engine is extremely low due to the displacement action of the compressor stages, relative to the surrounding atmosphere. As the water vapour in the air reaches this low pressure zone, it condenses to form visible water droplets. As the vapour is compressed, it evaporates and dissapears. The air must be very humid to create such a dramatic display. Probably the result of a recent rainfall, the results of which we can see on the ground.
@likeawhispr
15 жыл бұрын
simply air moving fast at such a rate that it's starting to condense, that is why you see the water vapor before the engine even has a change to "compress" it. Basically the same thing that happens when air moves quickly over an aircraft wing at high angles of attack :)

@david2371 You cannot convert thrust to horsepower because you need torque and rpm to calculate horsepower. A turbofan engine does not produce any torque other than the torque needed to spin its own fan and compressors. It's only used to move air. However, you could look at the turboshaft version of the CF6-80C2, which is the LM6000. It's basically this engine without the fan and with more turbines to get all the work possible out of the airflow. It's rated at 57,330 shaft horsepower!

the engine wasn't in TO power for all the vid, plus on an actual takeoff it would be in that setting for a longer time, companies that manufacture engines run their engines at TO power for much longer. The fence behind the jet is built to prevent jet blast from reaching other parts of the airport, so it's built for that kind of beating.

@nicolasdmg11 because as the speed of the engine goes up, the dynamic pressure also goes up, so the static pressure decreases a lot. At low pressures the water and almost all of other liquids boil al lower temperatures, so the water present in the air and in the ground around the engine is sucked and boil almost instantly. I hope you have understood. Cheers

thats true, and i think T/O power stands in the range of 80-90% but that could be higher if the plane might be close to or is at maximum take off weight. and yes you can blow a jet engine on a 767 just as easily as you can in your own street car by over revving the engine. only when a jet engine blows from high RPMs what youll see is alot of smoke, or worse the engine could explode violently

I wouldn't be that close, unless the person is far and zooming in. When we did our engine runs after balancing the N1 fan, we both were staring at the instruments, one guy at the controls and the other writing numbers down. If the airplane would have jumped the chucks we wouldn't have known for at least 2 seconds, then realize the airplane was moving, power back and brake. Enough time, I think not. Also the opposite engine must be at least 80% power to keep it from turning, jumping the chucks.

@ligerfly You said it! I'm an aerospace engineer and if you really know your stuff, you'll see that piston engines are a joke compared to jet engines. If you took the fan off that turbofan engine and attached it to a piston engine, you wouldn't be able to spin it at even half the speed because it would require so much torque at such a high speed, which piston engines are incapable of. It is actually physically impossible to build a piston engine that can match the power of a jet engine
