For sure, the Honeywell's heating installation in my house works better than this engine probably would, since the animation indicates the fan rotating the wrong way round...
The TFE731 engine is a geared turbofan design. The fan rotates in the CCW direction at 11,667 RPM. The N1 and N2 core stages turn in the CW direction on separate shafts at 21,000 and 31,173 RPM respectively (TFE731-40). All these speeds are at 100% RPM. The fan is connected to the N1 stage through a planetary reduction gearbox with a gear reduction ratio of 0.555. The animation is incorrect with respect to the fan rotation direction. (CW = CLOCKWISE, CCW = COUNTER CLOCKWISE, AFT LOOKING FORWARD)
hello brother.can you please solve me this question that tfe731-2a-2a gives us 3600 pound thrust .including core+bypass thrust. my question is that why fan rotates counter clockwise while the whole compressor section and turbine section rotates clockwise?
@@mrpiplanofficial The TFE731 series engine employs a novel feature…a geared fan. The fan is driven through a planetary gearbox and thus rotates in the opposite direction to the N1 and N2 core stages.
@@mrpiplanofficial Sorry, I hadn’t had my morning coffee yet (LOL). Gearing the fan allows it to operate in cruise at a slower RPM (about 1/2 the speed of the N1 rotor) and a higher efficiency. Thus the core and the fan can each operate near their peak efficiencies which results in a better TSFC (Thrust Specific Fuel Consumption). Pratt & Whitney uses the same technology in their geared fan engine. I hope this answers your question.
The entire hot section is turning backwards with the front fan🤷♂️I think. I’m no aviation expert but it looks like the front fan and turbine hot section should be counter rotating to the cold side compressor
Spinning backwards at first I was hopping that the front fan was held on with right handed threads and they where unscrewing it to show exploded view 🤣Lol Rolls Royce had a animation wrong also where the thrust was exiting the engine where the rear spike was located instead of the annular ring around it.
DONALD TRUMP... Should know that in the last six years Honeywell has layed off all the machinists who actually have the expertise to make these engines at 99% quality success. Mexico and the Czech are about 50% success, and a 3x delivery schedule

I like watching this video keep going 🤠 greeting from Morocco*@
Well... Wouldn't it technically be a 4 stage axial (LP) compressor and a single stage centrifugal compressor (HP)?.....
This is Honeywell turbofan engines .
It is turning backwards

i know about this that fan gear box makes its direction opposite but what is the advantage of making its direction opposite?
will it not produce the max thrust if it move in the same direction?

ฉันคิดว่าใช้คลื่นไมโครเวฟแทนการจุดระเบิดแบบเก่าๆน้ำมันมันจะสะอาด
สมองกล..กลศาตร์.
That animation and editing effects don't work and are bad taste

Help Honeywell Engines Donald Trump. (you're our only hope)
Honeywell engines are shit they are made in the check republic and are excepted to a Lower standard.
Hahahahahaaa I have 1000's of worry free hours with these motors. Obviously you have no clue what you are talking about
