Boeing brings back the 737 Max but also lays off thousands

ciaran

Re: They are to big to fail

Airbus has a "Airbus U.S. Manufacturing Facility" in Mobile Alabama, where they produce A320 family planes since 2016.

I believe that Northrop Grumman has a big hand in the Boeing fighter programs, so they could probably take over Boeing Defense. But I agree, the US fighters are in a dire situation between obselescence and disfunction, both causeing increased costs and lower availability. They should probably look to replace their older F-16s with the Gripen.

Re: "more than a dozen initiatives focused on enhancing workplace safety and product quality"

Airlines pay a deposit when they order, but they have a loan arrangment to cover the total cost of the plane when they receive it. So taking possession of the airplane is cash-flow positive - they get their deposit back, basically. Which for certain airlines is a very important consideration...

Re: !!!

Yea, I do agree, that's my upvote. Lets say "unfortunate" design choices and split the difference. I do think the Rafale is more polished, benefiting from the deep experience and single-mindedness of Dassault (at least at the time).

Re: Superiority

The US pours all its money into offensive weapons like aircraft and carriers, meanwhile Russia pours lots of money into missiles. Turkey bought the S-400 because its way more effective and way cheaper than anything the US has.

Missiles are defensive. Aircraft can be defensive or offensive. Therefore the US is scarier than Russia, amirite ?

Re: As a tax payer...

Thanks for the upvote!

I am consistently amazed at what fighter aircraft manufacturers will say! I have never seen one admit to a restriction or a liability. Sometimes they do leave in a kicker to stay honest, like "... when we get the budget".

Anyway, the Typhoon engine air intakes look "difficult" to make stealthy. They're rectangular. And I don't remember anyone saying that they have an "S-bend" to hide the turbine blades from direct radar illumination. On the other hand, in the Rafale backstory there is a phase when Saudi Arabia asked for "low radar cross section". That happened just as they were going from prototype to final design. The story goes that the final aircraft looks just like the prototype, but that "nothing is the same". Dassault markets the Rafale as a "Discrete Omnirole supersonic fighter". Discrete as opposed to being "Oh my Holy God" obvious.

Typhoon gets the message out about using RAM (radar absorbing materials) but doesn't really directly say anything about their cross section. Rhere's no official published radar cross section info from any the respective manufacturers.

The F-35 says its "really good" form in front - not so much from the back and sides. The Rafale has a huge flat tail that's probably easy to pick up from the side. Your milage may vary...

Re: F16 vs F-35

Both Boeing and Dassault say their planes are compatible with ski-jump aircraft carriers. In other words both want to sell to India and will do what it takes to make that happen.

ciaran

Re: !!!

Dassaut were producing "delta wing" fighter jets since a long time. The company building Typhoon was created from scratch. Typhoon and Rafale have a similar "delta canard" design. Which final design is probably the best?

Have you noticed any design faults on the Typhoon?

First the canards are so far forward that the pilot's view of the ground is blocked. OK for air-to-air, which was the Typhoon's original target.

Then the wheels fold up laterally into the wings, making it more difficult to put extra tanks and heavy weapons close to the centerline - on the Typhoon they're all mounted wayyy forward. The wheels on the Rafale fold up longitudinally.

The great one is how the Typhoon sales people have always criticized the Rafale for being designed to do everything from the beginning, whereas the Typhoon was specialized for air-to-air. But now they've stopped saying that because they're trying to compete as a multirole fighter

Re: It's welded solid.

I seem to recall The Register doing an article on that. The UK govt was "just asking for a friend" if they could share desk space with other fighters, like F18 or Rafale... The question coincided with a love-in between the UK and French militaries. BAE panicked, thinking the F35 contract was at risk, and used the UDP party line - Ulster says "NO" !

ciaran

Re: As a tax payer...

Or they're embarrassed about how much they cost to produce and maintain. They have great aerodynamics and best-of-class stealth, but terrible avionics.

The Eurofighter is easily a better airplane than the F22, but it like a lighthouse on radar unfortunately.

Either way, neither a F22 nor a Eurofighter will ever take off from an aircraft carrier, way too big.

ciaran

Re: F16 vs F-35

The F-35 prices are still a bit fictive, I won't put my money on the F-35A actually being useably produced for less than $100M. The F-16 "total cost of ownership" prices can be reliably forecast (although not by me).

However for a carrier aircraft, India is looking at either the F-18 or the Rafale, so best choose one of them.

Yes, in a shooting war, the AWACS, the Tankers, and the Aircraft Carriers will all be smoke after the first 36 hours. Still, an aircraft carrier without airborne early warning is a sitting duck.

'Software delivered to Boeing' now blamed for 737 Max warning fiasco

Re: Red herring

No, its clear that the pilots in the second crash tried to do what Boeing said. However Boeing gave incomplete information to the pilots. Once the MACS is "stuck", there are incredible forces acting on the control surfaces. So the "manual trim" procedure is basically impossible.

In the old, old days the Boeing flight manual gave a real procedure on how to recover the airplane, but it has been airbrushed from history. Expect it to come back in the court cases...

Many uses for a lighthouse

You'd think so, but actually lighthouses are just general navigation beacons.

You get big powerful ones that you can spot from far away as you approach the coast from the sea, these tell you basically which part of the coast you're approaching. Then you might get a smaller lighthouse to signal the clear water channel to approach a port. Any dangers they warn about are basically irrelevant to a boat of less than a ton.

Also many lighthouses don't illuminate 360 degrees. If only because then the local villagers can't sleep, but also to only cover a particular danger or channel. So even if it was working its feasible that it wasn't identifiable in the fog.

Reverse engineering is not forbidden by law. Your favorite breakfast cereal can be reverse engineered by your local discount supermarket. So you can look at an existing product, write down the spec of the value it provides, pass the spec to a team that will produce a lookalike, and iterate over the process untill you get a marketable product.

The law says that you can't copy. So the team isn't supposed to see the existing product. That's ensured via copyright protection. The law also provides patent protection, but no only for reverse engineered products.

I was told that 20% of products put to market fail because "they were only coping existing products", and I thought "that's excellent, lets do that!".

National ID cards might not mean much when up against incompetence of the UK Home Office

Some things the government should know..

I think the government should know all the people who are legally resident, if for no other reason than to tax them. So there should be government-issued cards with your name and face. From there you can bring along any other documentation to prove anything you need proving like your date of birth. I see no reason to put your age, sex, social status into the card.

The card should have an ID number which should mean absolutely nothing - it should just be an external key into a database, and it should change every time you renew the card. The card should have an expiry date, of course.

Frankly they are lucky that the older F35B are still usable.

Re: and Pigs might fly a.k.a F-35

In any case if you turn on your radar you're not stealthy any more.

No matter how much hi-tech jumping around you're doing, if you outputting 10's or 100's of watts of power, you will be detected passively by anyone in range.

ECM is a good approach. It helps if you're not built like a mirror, so having a small radar cross section is an advantage. How small is an economics calculation vs. the cost of the ECM. In this the french Rafale is a better design than the Eurofighter.
