Aviation Geeks unite?! Anybody else care about planes here?

My amateur and probably poorly informed suspicion is fuel system controller (FSC) shutdown due to thermal stress, starving the engines and leading to electrical failure and RAT deployment. However, I would have thought that such a vital controller would be multiply redundant against failure.

Here's another possible cause of engine starvation discussed - vapour lock - again due to thermal stress:

Great channel for learning about such things.

Yeah great channel. I posted one of his videos on the previous page. Very interesting stuff indeed

He was lagging a bit on some of the information that was available, but he seems to have caught up.

starting about 5 minutes in a technical look at the systems on the 787-8 that people are attributing to the Air India crash.

last section is the RAT and the causes for it to auto deploy as it's unlikely the crew deployed becasue they would have had to run through the checklist first and there simply wasn't time.

first part of the video covers changes that Airbus has made to the Neos regarding drain masts

Cool video I found. I love the 747

Another really interesting video. Pilots using varying thrust from one engine to steer the plane and perform a landing in the most adverse and critical conditions

Next time do provide a little more information, like what topic it is actually about, so kinda like "Another really interesting video about duck feathers being used in the heat shields of satellites!"

Yes I edited my post

Thank you!

FAA has lifted the ban on supersonic commercial travel over the US. That will make investment in Boom a little easier to justify.

Now to see if anyone wants to go down that road again with them.

Now to see if anyone wants to go down that road again with them.

For Boom's Overture SuperSonic AirLiner, they already have a very decent OrderBook.
They have 35 Confirmed Orders & Option for 146 Aircraft.

That's all Pre-Orders from some of the largest Airlines in the world.
- Virgin Group
- Japan Airlines
- United Airlines
- American Airlines.

They already have customers lined up with Pre-Order money taken.

And Overture's Seating Capacity is decent at 64-80 Passengers.
Every Single Seat is Domestic 1st Class with a Window & Aisle for each seat.
Ticket Prices are expected to be Business Class Pricing.

As of January 2022, the Overture's first flight is planned for 2026 with introduction into service expected in 2029

I don't think that 2026 date will hold, but people have written Boom off over and over only for them to keep returning. It's interesting how little their test plane actually did before the finished tests. I guess the fluid dynamics and the other stuff can be modeled so well by simulation now, they mostly just needed XB-1 to prove to everyone it could fly relatively quietly supersonic.

Regardless of when their "Actual Date" of completion is compared to their initial public projections, as long as they're making steady progress, I'm happy.

I think their Test Plane really was only to validate their Fluid Dynamics model and the AeroDynamic Features they require for Overture.

After that, go make the initial ProtoTypes of Overture and test & certify that sucker.

So if Boom is successful do you think SSTs will become fashionable again?

So if Boom is successful do you think SSTs will become fashionable again?

If they meet all their promises, very much so.

It's going to change commercial civilian aviation.

Slowly, all Airlines will split between "Premium Seats" on the Overture which goes SuperSonic.
Regular Planes will be slowly converted to "Regular Seats" that replace the wording for Economy Seats.
There will be only Regular & Regular+ (Exit Aisle) Seats on Normal Planes.

EveryBody will move their "Premium Customers" (First Class, Business Class, anything more expensive than Economy & Economy+) into the Overture.

Being able to get to the destination and back within the same day 2x is going to be "Game Changing".

I wonder if it is possible to fast rope under auto-rotation—rope winched back at same rate of descent for a quiet way to put soldiers down—then crank up once they hide. That might explain the tail damage.

I wish the Commanche became a Operational Helicopter.

Oh blended wing body. Video about Jetzero concept plane, blended wing body, engines on top

I can see the US Military buying into it for a Tanker or Cargo Transport.

The regular Airlines wouldn't be into it due to "Logistics".

The Cost + Maintainence + Training difference wouldn't off-set the benefits.
