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

[Marc]

I know a few 380's have been called back to life recently but it does seem like the airbus 350 and the 777-9 can pretty much do what airlines need, now, and with 777-9s folding wingtips it can fit well into current airports

I know QANTAS has done so but they've complaining cos it takes about 4500 man hours to resurrect one but at the same time a lot are still heading for dismantling and scrap (read this week that china southern have sent their 5 to the recyclers).

Though even the A350s might be too much for some airlines. SAS have terminated the leases on 2 A359s they had with the aircraft going to storage.

Pilot of an F-35 had to eject after a vertical landing went wrong.

Aircraft had touched down but then pitched forward as if the vtol engine spun up and began to pinwheel at which point the pilot decided to get the hell out of dodge.

wow. boom said it would have an announcement by the end of the year, and they actually did. GE additive can handle small scale manufacturing so they wouldn't run into the problems that RR had with the venture.

NICE! I'm so happy for Boom AeroSpace.

Sounds like a Avionics / Computer issue that triggered the VTOL engine to spin up after landing.

really fail to see how these or your previous post in here add to the discussion and are little more noxious link bombing.

Though for something that is more relevant we have a video on the conversion of an A330 (ex-Thai Airlines) from a passenger jet to a cargo freighter.

I've been enjoying going over copies of the WW2 "Army-Navy Recognition Journal" on the Internet Archive. It's wartime publication so not everything is accurate, but there's some really interesting aircraft stuff in it (plus ships and armored vehicles).

 

[Marc]

Boeing and NASA are collaborating to develop a passenger airliner design that could be the way of the future and making them 30% more fuel efficient than current designs.

the design combines a high wing design similar to that seen on military cargo aircraft with a very long and slender wing (think the U2) that would have struts for bracing.

Target market would be short haul which is the market 737/A220/A320/CRJ)

https://www.msn.com/en-ca/news/tech...vid=f4ab09d84a8a4f1d89a773770445d738#comments

Other than the BAe-146 I can't think of any other jet airliner that's used such a design - though there are few prop driven one such as the Dash-8.

Can see some issues they'd have to face - starting with the length of the wings which as noted in comment on the article was a major factor against the A380s.

The undercarriage would also need a radical redesign. There won't be a wingbox and wings to leverage. The Dash-8s for example have the gear retract into the engine nacelles but that's not practical on a jet engine. There's the pod/fuselage apprach used in military aircraft but they aren't carrying passengers and luggage in the same way - plus they tend to be fairly wide.

discussion on the F-35 crash abooard the U.S.S Carl Vincent 13 months after the release of the accident report.

Accident put down to the pilot error due an unfamiliarity with the type of approach which compresses the time frame for the landing checklist leading to mistakes including being too fast on final.

Recommendations are being made to procedures for the approach and working with manufacture for updates to the systems notifications.

The type of approach being flown has also been banned.

Pilot has been grounded but will keep his wings and two on the flight deck were injured in the crash, one severly resulting in a 500mile sea level flight on in a UH-60.

looks like the first of the 787-8 is heading the for the end of the road with a contract being awarded to a Scottish firm being award the contract to dismantle two of them.

At this point which aircraft are to be dismantled is unknown. The oldest is still flying with a Japanese carrier with American and Ethopian Airlines having jets of a similar vintage (2011-2012) and no indication that any of them are being withdrawn.

One thing about the 787s is none have been been scrapped show there no actual supply of second hand equipment and materials so what comes off these two jets will probably go quickly.


The other thing about scrapping the 787s is the carbon fibre in the fuselage and how that would be processed.

So you're you're next for scrapping?
