The vortex is forming as the air travels just above the ground from every direction and meets right under the nacelle lip. The coriolis force makes the air lean right or left thus creating the circulation. It's close to the formation of a hurricane where you have low pressure at the center drawing in the air from every direction and pushing it upwards. The coriolis force pushes the air slightly off center cause the rotation. Other factors like wind direction and interaction with the aircraft/engine/exhaust play a part as well. As for the condensation, the high Mach through the inlet drops static pressure and temperature. Total temperature and pressure hold almost constant. As explained, the drop in static temperature increases rel. humidity to 100% and start the process. There are other factors that weren't mentioned that have an impact on the "cloud": you need particles in the air to start coalescing and form water droplets, and residence time.

Music to my ears

Wat een power!!!

People in the cockpit can get a rough ride if there is any wind during the run. The bouncing around is much worse in airplanes powered by large turboprops. Back in the day, running the Convair 580 up to power with any wind present led to a lot of turbulence around the propeller, which would have the airplane dancing on its struts. The gust lock had to be unlocked in order to advance the power levers, so the control wheels would be banging around unless they were firmly held. Under those conditions, even seeing instrument readings correctly, much less writing them down, was a real struggle. It was a two-person job, at least.

Music to my ears.

And this, in a nutshell, is why turbofan engines are awesome.....period.

Fantastic video! Am a massive fan of your videos MrIFixplanes, the information you post is great too and gives an excellent idea of how engines work. Quick question, when the HP turbine blade tips are at full throttle and spinning at 1200mph, how is it they are not damaged by supersonic shockwaves? Is it due to the blade being completely balanced?

@mrifixplanes1813

9 жыл бұрын

The speed of sound in dry air can be calculated using the equation below, it's not the most accurate equation, but will suffice to make a point . The formula shows that as temperature increase, the speed of sound increases. V = 331.4 + 0.6T m/s where V is the speed of sound and T is temperature in degrees Celsius If we take the temperature to be 500C at the HP turbine, not unlikely and I would expect it to be higher at full throttle, then the speed of sound would be 1425mph. So you can see that even though the tip speed of the HP turbine blades may be at 1200mph, the speed of sound at that point in the engine is higher and thus the tips are actually travelling sub-sonically. The Fan blades tips do travel supersonically however. Due to their design, the angle reducing towards the tip, and their construction, either hollow titanium with internal webs, or carbon fibre laminate, they are designed to withstand any negative forces. The Fan blade tips do suffer from a drop in efficiency by going supersonic, but that is traded off by an increase in efficiency towards the blade roots of the fan. The central part of the fan disc feeds the inlet to the core engine so the overall efficiency of the engine is maintained. Hope that answers your question, thanks for the positive comment, and thanks for watching.

@233kosta

Despite spinning that fast there are no shockwaves. The combustion products entering the HPT have the consistency of jam (really really REALLY hot jam :P). The mixture of fluids has been altered, so despite obeying the same rules of compressibility, the outcome is somewhat different. The speed of sound in an ideal gas (perfectly compressible, etc.) is given by the square root of gamma*R*T, where gamma is the ratio of specific heats, R is the specific gas constant given by the ideal gas constant divided by mean molecular mas, which for air is about 28.8, and T is the absolute temperature in degrees Kelvin. Gamma for air is about 1.4, but it's about 1.333 for combustion products. This serves to lower the speed of sound somewhat. However considering that the adiabatic combustion temperature of Jet A-1 is about 2500K and the HPT is pretty much directly behind the combustor, you're still looking at a speed of sound in excess of 900m/s (2000mph). The big problem with HPT blades is heat. You've got combustion products more than twice as hot as the melting temperature of the superalloy, which means you need excess air in combustion (like you get in diesel engines) to keep the turbine entry temperature at an acceptable level. This is a problem, because that excess air has to go through the compressors, have a load of work done to it, and then not burn, resulting in a loss of efficiency, thus having a higher TET automatically grants you higher efficiency. Three ways you can raise TET without wrecking the engine - run colder air (usually from the HPC) through the blade (and exhaust it through holes on the blade to form a film of colder air - known as film cooling), mess with the alloy to make it more stable at higher temperatures and coat it with a ceramic for extra insulation. Engine manufacturers usually employ all three, and still the engines run at the limit of the materials when you apply take off thrust. One could argue that at that point they're even running beyond their capabilities (hence time limits on take off thrust). Regardless, they do get damaged throughout the lifecycle of the engine and eventually need to be replaced (look on ebay for RB199 blades, they're likely at the end of their lifecycle. That's what a blade looks like once it's done its time in the HPT :P). Considering half the engine needs to be stripped to get to them, it's a good idea to replace other parts which are nearing the end of their lifecycle at that time as well. There's a video on youtube of an A330 suffering a failure of a single HPT blade due to fatigue (at take off thrust of course :P). The blade was contained, but the resulting mass imbalance bent at least two shafts and rendered half the engine unusable. The video has an attached AAIB report if you're interested in the full extent of the damage. LPC blades on Trent engines specifically are still made of titanium with a support matrix within (very interesting way of making them :P), though if you've been paying attention to RR's PR stuff, you'd know they're looking at producing composite blades with a titanium leading edge (which will probably end up on the Advance and UltraFan models). The shockwaves aren't that big a deal structurally (though they murder efficiency), so the titanium leading edge isn't necessary for performance as far as I'm aware, however it ensures that a regulation sized bird (2kg I think) striking the blade won't shatter it. Despite making the blades look really sexy, it's a compromise from a mass standpoint, which also makes them a slight detriment to dynamic performance (heavier blades mean the fan spins up slower), though still a significant gain compared to all titanium blades.
