Boeing Says It Could Halt Production Of 737 Max After Grounding

The title of this post is the same as that of this article on the Guardian.

This is the first paragraph.

Boeing said it could halt production of the 737 Max jet on Wednesday as it reported the company’s largest ever quarterly loss following two fatal accidents involving the plane.

To my mind, this is a self-inflicted problem caused by trying to stretch a 1960s design too far past the end of its design life.

Boeing realised that they needed a new larger plane and developed the fuel-efficient Class 787 Dreamliner to replace 747s, 767s and 777s.

It was total management failure to not planning to replace the 737 with a smaller plane based on Dreamliner technology.

Will Boeing Solve The 737 MAX Problem?

Compare it with the Class 710 train, that also had software problems that delayed the launch.

  • The Class 710 train is a totally new train, with masses of new features, liked by operators, staff and passengers.
  • The Train Management and Control System of the Class 710 train was very challenging to design and program.
  • If a train fails, it only comes to an embarrassing stop.

On the other hand, the following can be said about the 737 MAX..

  • The 737 MAX is an update of a 1960s design.
  • The mathematics of the 737 MAX must be challenging.
  • The computer system hasn’t been properly designed, programmed and tested.
  • If a plane fails, it’s a lot more than an embarrassing stop.

Boeing seem to have made a tragic mistake for airlines, passengers and them,selves.

Engineers will probably solve the software problem,but will that be enough to save the plane?

How To Buy Airliners

I found this article entitled Ryanair Orders 175 Boeings, but CEO Wants More Seats, Less Baggage, whilst looking for an article about baggage.

It really does show how Boeing and Airbus are not providing airlines with what they want.

I wonder how long it will be before we are all weighed with our baggage before we go on an airliner. I wouldn’t object, but it would probably make flying just that little bit cheaper.

The Rivetted Wing

This picture of the wing of the 747 shows the rivets that hold it together.

747 Wing

By the way, the upturned end of the wing is an aerodynamic device to increase efficiency.

If you are on Airbus as opposed to a Boeing, you’ll see differences. 

For a start the Airbus uses a different end to a wing in that they have more of a sideways delta at the end.

But the main difference is that Airbus glue their wings, whilst Boeing use rivets.

Glue?  You  might ask.

But they have doing it for years.  In fact the technology was first started by de Havilland and was applied very successfully to the Mosquito of World War II fame.  They then applied it to the Comet and Trident airliners before using it on all Airbus wings.

The advantage is that glue carries the loads between the parts of the wing continuously, whereas with rivets the stresses are carried only at points, which have been weakened by the rivet holes.  This means that it should be possible to have a lighter wing for the same strength with glue.

Some technologies may seem strange, but don’t know them if they work.
