Re: The Chinese built my perfect airplane...

Carnot has left the chat. I didn’t quite understand his engine when I took chemistry. It would be fun to review. In the meantime [not_italics]we are planting soybeans. How are things with you at the water-splitting, carbon-reducing oxygen factory going? Carnot’s only going to be using a limited amo...

Who cares about DC-9s and 757s and 737-MXs?

What we really need is an airplane to haul windmill blades, and by golly aeroengineers are working on it!

Because it’s good for the climate to burn jet fuel to fly blades, one at a time, and they still have to be trucked to and from the runway.

Re: MCAS…

Evanie cites a need to reboot the computer occasionally. I guess Boeing didn't expect their aeroplanies to last 22 days , let alone 240. In all fairness, neither did I . Did you make a typo? 18 months is 540 days: our generally-agreed longevity estimate. Evanie’s no fly list? They handled this bett...

DC-9

BAC 1-11

ERJ 145, 175

CRJ

And I think I missed one or two.

Do you think it makes suction vortexes when powered up for takeoff?

Cousin-in-law.

I have a fourth cousin-in-law (something like that) who is an engineer (the train-driver type) who made two, share-worthy comments. 1. There is a pay bonus for fuel efficiency. I’m thinking that diesel electric locomotives have a pretty simple MPG procedure with engine speeds and controlled electric...

Re: Railroad Thread

My collection of very bold comments and displeasure with 3BS’s adjectives on this topic suggested an unrealistic view of the ability to improve it. I have been always amazed about how bad trains brake, and I don't understand why. Fixed. I answered the why (it’s as good as the brake engineers can ec...

Math….

Ass-uming constant deceleration, what is the deceleration rate of a train that takes a mile to go 60 to zero.

Don’t tell me, I’m going to get a pen and paper, and do some ciphering.

Re: Brake summary

I'd love to learn about that. I’d enjoy learning about it, too. You know that behavior of “we insiders know, and you outsiders don’t know?” It’s really strong in the RR world. You cited the Westinghouse air brake development, and that it was a long time ago. Since that time there has been rather li...

Re: Railroad Thread

I wonder if under the right circumstances, train brakes being more effective could make the rail move fore-and-aft?
It’s firmly connected to miles of rail each direction so it can’t slide too much.

There was a classic runaway train Swiss cheese automation fueled derailment in CA.
