    NEOL.world - anyone tried it yet? Copper to replace ZDDP

    Copper additive chemistrys are nothing new as RLI used them years ago in their bio-oil formulations. Where is the data that shows that copper chemistry mitigates hydrogen embrittlement in Fe alloys? I am not sure if this post was meant to be a discussion of copper additive chemistry or a...

    2020 Ford Ranger Mercon ULV 36k mi

    @Brian26 For the relatively low mileage on the fluid, the Ford Mercon ULV sheared somewhat. I would think HPL's ATF Teal would serve you better. file:///C:/Users/Phil/Documents/Formulation%20and%20Automotive/ATF%20and%20PSF/HPL%20ATF%20Fluids.pdf If this shows anything, I think it shows, on...

    Well, not all of the 18+ chemistries in an ATF are visible in a conventional analysis.

    Air India Flight AI171 (Boeing 787-8) Crash

    That is the most irresponsible conspiracy theory I have seen so far, and has never been put forth in the popular press as a valid theory. Once the FDR data is written, it can't be faked. Neither can the FADEC logging data. If you have ever heard of the FADEC, it stores engine parameters. FADEC...

    MolaKule Q&A on Aircraft Structures VII Engines

    Yes, the GE9x with 110,000 lbs of thrust will power the Boeing 777X.. "The General Electric GE9X is a high-bypass turbofan engine that has been developed by GE Aerospace for the Boeing 777X. The engine first ran on the ground in 2016 before being tested in the air for the first time a couple of...

    Air India Flight AI171 (Boeing 787-8) Crash

    After 16 pages and no definitive data from the Indian or NTSB groups, we still have no probable cause, etc. So let's take a break shall we?

    Anti-Wear Additives

    I am unsure by what you meant by, "compromises." A formulated motor oil is a balanced mix of various base oils and various chemistries. There can be a combination of antiwear and other chemistries in the formulation as long as they are synergistic and do not conflict with one another. The zddp...

    Right, so that is an average of ~ 0.3L/hr per engine. Aviation oil system: https://www.aircraftsystemstech.com/p/air-oil-coolers-two-basic-types-of-oil.html

    MolaKule Q&A on Aircraft Structures VII Engines

    We know from previous BITOG discussions that a specially formulated POE oil of ~5 cSt is used to lubricate the engine's bearing cells. Bearings support the drive shafts: "Bearings are lubricated inside a bearing sump [cell], which is sealed. Often labyrinth type seals are used together with...

    MolaKule Q&A on Aircraft Structures VII Engines

    Take for example the P&W4000 as used on the B767 and Airbus models: https://en.wikipedia.org/wiki/Pratt_&_Whitney_PW4000 Bypass ratio = 4.8 Two-Spool Design (two drive shafts) with high and low pressure turbines Inlet (fan tip) diameter = 93.4 inches Thrust range is 50,000 to 65,000 pounds...

    MolaKule Q&A on Aircraft Structures VII Engines

    According to Newton's Laws., any jet engine develops thrust by imparting Momentum to the fluid passing through it. I.e., Momentum - Mass of air X Velocity of the air. The sum of the momentum of the bypass air + the momentum of the exhaust gas gives rise to the total thrust of the engine.

    MolaKule Q&A on Aircraft Structures VII Engines

    THRUST: The force that a jet engine develops and the one that drives the plane forward in normal flight, is called "THRUST." The engine thrust is transmitted to the pylon, then to the wing spars or empennage, and then to the fuselage. Supply the missing word: According to Newton's Laws., any...

    How to become a regional airline pilot ?

    You're highly misinformed. You missed the info in post #3. @Dave Hess Getting a degree helps if you cannot find a pilot's job right away. https://erau.edu/hub-spoke/stories/how-to-become-a-pilot https://erau.edu/degrees

    AGAIN...what's the 'best' engine oil for me?

    i think the HPL 10W30 No VII oil would be a good choice.
