    Most Beautiful Aircraft Ever Built

    First time I saw Porter, about 1962 or 3, I though it resembled a rat with that long nose and what I remember as a 5 bladed prop. It sure could land and take off in a super short distance, though.

    Most Beautiful Aircraft Ever Built

    I don't see any such listing in Wiki, Blackburn Aircraft - Wikipedia, Not that Wiki is the be-all and end-all. But it does show the Blackburn R1 Blackburn as noted in #624. OK, after re-reading, it looks like I missed your point. Senility is slowly setting in. And yes, it certainly resembles a...

    According to Wiki (Blackburn Blackburn - Wikipedia), it is a Blackburn R1 Blackburn. So good that they named it twice.

    Celera 500l Progress

    I remember this guy. My wife and I would watch him whenever we needed a good laugh. Didn't know about the 747, but am not surprised he had one.

    Yet Another Airborne Camper

    The thing sticking out of the nose looks a lot like an air-to-air refuelling probe. You never know when you might need gas.

    Concepts only: Doodles without numbers

    Think Beech 1900. It must hold a record for added fins, strakes, et al.

    Round number for heat treatment?

    I agree with what you have said here, but here is the rub; making parts out of 2024-T3 requires a larger bend radius than parts made from O, depending on the material thickness, which may or may not be a deal breaker depending on where the piece fits into the puzzle.

    Round number for heat treatment?

    If you are solution heat treating 2024 you need 919F and for annealing 2024-T3 you need 775F, as per Aluminum 2024-T3. A little outside of the range of your standard oven. You would need a proper kiln, plus precise controls. And then be able to check the hardness in order to ensure that...

    Round number for heat treatment?

    Ribs , or any other part, that is made of 2024-O, when heat treated will be immediately quenched when coming out of the oven. This is what causes them to resemble pretzels. It is then aged for 96 hours during which it reaches temper. After quenching it is still soft, it is W condition, and can...

    Round number for heat treatment?

    This is how the OEM that I used to work for made most of their 2024 parts.

    Round number for heat treatment?

    Testing is actually pretty easy, one way is with a Rockwell tester, which checks the hardness of the aluminum. Five minutes per part, max. You just need the tester, which I'm sure isn't cheap.
