The Great Ongoing Aviation Thread (general and other)

Def. Louder than my fridge

A friend of mine had significant hearing loss on one side thanks to a wrong place, wrong time incident involving an Allison V-12 startup.

Merlins were the preferred engines in unlimited hydroplanes for years, leading to the term “thunderboats”. They’ve been using turbines a few decades, and I still see complaints sometimes about the lack of noise, now.

Don’t forget the Bentley Meteor, a one-off bespoke car featuring a Merlin engine on a Rolls Royce chassis. Top Gear tested it back in 2012 against the even more absurd Brutus, which has a 47 litre BMW aero engine: Bentley Meteor | Top Gear Wiki | Fandom

I could imagine some turbine-electric machine that delivers 2K horsepower to each of 4 wheels.

Zero to warp speed in 0.0001 seconds.

You’ll need to divert a portion of that power to a large fan that sucks it down to the track. Gonna be traction limited otherwise, at least at low speed.

Depends on how many yards / meters wide your tires are. :wink:

It only slightly depends on that! Double the contact patch, halve the ground pressure. Partially balances out.

There are some non-linearities, and something like a dragster can be literally glued to the surface, so it’s not quite as simple as that. But without special preparation, it’s gonna be hard to deliver 8000 hp to the wheels. Top Fuel dragsters manage it, but not much else. But that’s without fans! With active downforce, you can do a lot more.

Isnt there an EV with succión fan that has crazy tracción?

This is the only one I know about:

0-60 in 1.55 s is pretty good. But they could do better…

How about under one second?

D’oh! :man_facepalming:

Thank you.

59 years old seems very young, especially when pilots are subjected to stringent medical examinations.

Presumably Boeing can’t be blamed for this one.

The incident occurred in an Airbus. Unless… Boeing engineered it to shift scrutiny from themselves! (♫ DUH-duh-duh ♫) :wink:

So it is Boeing’s fault, I knew it!

As the docs will corroborate, in about 25% of cases in the general public the first sign of coronary artery disease is the sudden cessation of living. Screening catches some high risk patients, but not all.

There’s always the question of how thoroughly the docs are looking. I don’t mean to cast aspersions on the airline or authorities. But a professional pilot with an inkling of a health issue faces the ticklish decision to vigorously pursue the testing needed for diagnosis and treatment and perhaps end their lucrative career. Or look the other way at whatever symptoms they may be experiencing and hope for the best. Everywhere I’ve ever worked there were lists of which docs would pass you as long as you were strong enough to sign the credit card chit. I personally never subscribed to that approach, but some folks did/do.

Human nature being what it is, at least some pilots choose option B.

Nah - if we’ve learned one thing, it’s that they can’t engineer shit.

The recent incident in Las Vegas by Frontier is confusing. Initial public reports were smoke in the cockpit, no communication with pilots and then very hard landing. I assume tires blew from stress of hard landing but does anyone know what caused original issue with smoke?

Just a curious layman.

I haven’t heard anything about an incident with Frontier in Las Vegas. Can you provide a link?

But generally speaking, if this was very recent it’s likely too soon to know the exact cause.
