Having an FB account sometimes pays off when you lurk the rare warbird groups. This is a J29 and a lot of veteran pilots have joined for anecdotes and sweet stories to share just this year. Feels like it's my dutch angle. One user recalled how he visited a certain army base with friends a certain day in the 1960s and how one J29 pilot impressed the whole gang by flying low and buzzing treelines, how he got seriously into planes that day. That very pilot replied later in the evening, mentioning there was a group of kids looking awed spectating

I wouldn't swim at maho beach personally, because of what leaks out of airplanes. The French side is quiet and undeveloped. If you rent a scooter, never let it leave your sight. Scooter theft there is a racket by the rental places to fleece money out of tourists and backed up by bent cops.

Did they go wrong by contacting the tower for "instructions" rather than "clearance for an emergency landing"?

Siemens appears to be no better. This page is light on technical details but at least has a list of our current products. I also found the similar page for Siemens.

It's entirely possible that there might not be any details until you've started talking to a sales engineer about what you need, and they've started going through the motions of figuring out if it can even be built. That, plus they might not think they'll lose sales by not making a website for these one-off products.

This is the sort of product that .. if you read the brochure... has something like a 10 month delivery and installation time. Products like that are bought after months, or even years of negotiation. .... I work in an industry where the core equipment can be the same sort of thing. This may just be the mark of the "more than a million dollars" market. Delivery times go up, prices stop being fixed, and corporate sites for the products start being pretty and more or less content free.

Yeah, I know a similar industry - when there's basically one or two suppliers to buy from, it's expensive enough to have incredibly low production volume, and all the equipment is so specialized as to be unique-build per unit, well, what's the point of even pretending there's a standard model to sell?

I deal with engineered products literally all the time and in my industry there is typically a standard "design" (albeit might have several "sizes" of each design) which will be the basis of the unit which will then be modified/customized, sometimes incredibly so, for each application. It's not really cost effective to reinvent the wheel for each item. A lot of time data is not published because they don't want to give competitors any information at all or, more commonly, be pigeonholed into something when they shouldn't be so it's just best to talk to sales/engineering to see what they can do.

That reminds me of something I wondered years ago, how different are industrial units from aero-propulsors? As in could an industrial producer create a competitive jet engine (if they made a serious effort) (and were as stingy with money as the US Senate is to LockMart)?

It's extremely expensive/laborious to redesign for weight and packaging, so I don't really see the point. Going the other way is kinda cool because you end up with easily transportable units.

That's a good question. They probably don't have any facilities for driving accessories. And then the industrial producer would need to sort out aviation quality accessories. Though.. GE is already an aero engine producer. And it appears that Siemens sells some engines that had aero lineage. I can't imagine the engineering that would be needed to get the weight out of the industrial units. Those things seem to have "beds" versus casings. And from what I can see, their combustor and injector setups aren't exactly slim either, so the deck is quite stacked against that sort of conversion.

Pretty sure Siemens recently purchased the aero-derivative unit from Rolls-Royce. They didn't offer those sorts of solutions until pretty recently. I believe most of the customization with large frame turbines comes in with the plant design. I'm just a turbine guy so I don't really know much about specing out plants and MrYenko posted:Industrial combustion turbines are also a LOT less sexy then aeronautical jet turbines... this is mostly true. Aviation pays my bills so I know way more about their stuff. However, I've been working a little bit more with Power recently and have gained more appreciation for these giant machines. Something that has the footprint of a few (like... 20?) shipping containers can produce almost 430 MW of power. That's really pretty impressive. But there's not a huge plume of fire and noise coming out the end, so maybe it's only interesting to dorks like me. Power and Aviation engines have some pretty different design requirements. For example, historically power generation cared a lot more about emissions than jet engines. They also try to run for months or years without shutting down, where even a long-haul Aircraft engine gets turned on and off a lot. But as you've both pointed out, weight and packaging are probably the biggest differences. Power engines do still worry about packaging inasmuch as they have to actually be able to deliver these things somehow, but that's not the same as trying to make the engine fit inside a 737 sized engine nacelle without pulling the wings off. And weight only really matters in the rotating components, and as a materials cost. Nickel is expensive. Anyway, this is why those are separated into two separate businesses within the larger GE umbrella.

Apparently when you fly to an airport and then wander around a bit you hear things like 'hey want to come take a look?' instead of 'you're not supposed to be here I'm calling security' like when you drive there.

It still had new plane smell. Also, this is my second time in a big amphib (first was a PBY Catalina) and flying boats really are flying boats and not floating airplanes. No idea what's in the bins but that white box is some oil system monitoring thing that even has remote magnetic pickups/sensors to detect metal shavings in the oil. They apparently had issues with metal in the oil at first because the can opener they were using to open the cans made a mess of things.
