Quick answer: Of the air entering a turbofan engine, some passes through the entire engine (the core); it is compressed, mixed with fuel, burnt, passes through a turbine, and exhausted. Some just passes through the fan; it is accelerated rearward and exhausted. The ratio of the two is the 'bypass r...
Jump to postA jet engine is a reaction engine. The amount of force (thrust) that it develops is directly proportional to the amount (mass) of air that it expels rearward or the acceleration it imparts upon that air, or both the mass and the acceleration. F=MA. It turns out that it is much more efficient to mov...
Jump to postAs big an avgeek as I am, I know very little about engines beyond the basics. I was reading about the new engine for the 77X, and I understood some but not all, and the bits I am missing seem critically important features and innovation.

Jump to postUnited needs more airplanes ASAP.... Yes, but what can they do asap? They seem to be at the mercy of the 2 big manufacturers and airframe/engine types. They will be getting more this year but it doesn’t seem like enough soon enough. Even if they bit the bullet and ordered 77X’s, when would they eve...

Jump to postEven the 737-900ER is a better CASM performer than the 757-300, though it's pretty close. On a pure operating cost basis, the A321neo and MAX9 handily beat it. In key markets at heavily banked hubs there is value to moving 234 pax at once (vs. 179-199 with the 321/739/7M9) but at this point the cos...
Jump to postAnything a 764 can do, a 788 can do better. Anything a 77L can do that involves UA’s network, a 789 can do much cheaper. We all know that most of the potential 748 customers spurned it for the 77W. The out-of-production aircraft that really isn’t replaceable yet is the 753, and I bet that if UA cou...

But you left off the 753, which I think DL or UA should order 20 of tomorrow if they could.

The following, silly hypothetical would potentially highlight what UA needs most even if they were old types. Say Jeannie (I dream of Jeannie) made Kirby a...

Jump to postI find so many problems with this suggestion. 1. United needs their 772ER for international ops as mentioned before. 2. The 772ER were retrofitted with nice interiors very recently. Why spend more on CAPEX? 3. Which "leisure business" class are you going to put on it? The 2-4-2 one they h...
Jump to postDelta's strategy is to consolidate older, less efficient aircraft (i.e., 717, 757-200) at fewer hubs and use them on shorter legs where the lower fuel efficiency has less impact, while the newer, more efficient aircraft (i.e., A220, A321neo) fly the longer routes. I wonder if this could strategy co...

Jump to postOn domestic routes, including Hawaii, which of the airlines that have flat seats up front have the most bed seats flying on any given day?
I would think perhaps UA given the HD 772’s with the old ITPE flat seats, but I really know nothing about what DL and AA do (or even JetBlue)
Thanks
I'm curios if the UA expansion is more focused on domestic or international? I mean for domestic, why not start converting the entire 772s into the high seat 360+ configurations? 70 strong domestic 772s on main sites can do a lot to relief the NB now to other domestic choices. I'm betting that is p...

Jump to postThe Instagram video United posted about these new routes ends with “The World’s Largest Airline”. On what measure or measures is United using to make that claim? I don’t think their fleet is the largest…yet, but will be.
Is it the number of destinations? Passengers flown?
Thanks!
The 777-300ER, 772LR (basically a 77W-SP with more characteristics of the 77W vs. 772ER) and the 777F all have the raked wingtips that make the wingspan 13 ft longer. Maybe there wasn't enough interest to build and certify 772ER winglets and I believe the 772ER wing isn't beefy enough for the raked...
Jump to postMay I ask a not so related question? I don’t know what thread to put it in, but given United’s huge fleet of 772’s, I’ll just throw it out there: Why didn’t the 772 ever get a winglet? If they genuinely save fuel, and UA has 74 of them, there must be a logical reason. She’s the only bird I can think...
