How Much Does a Pound Cost?

I recently read an article on the cost per pound for dieting programs.  When you factor in the cost of food, counseling, gym memberships, etc., it works out to $70-$100 per pound.  Unfortunately, most people gain most of the weight back after a diet program so the actual cost per pound is much higher.  The diet industry is clearly operating on a self-recurring revenue basis.

In the Aerospace industry, we hear a lot about reducing the weight of systems.  Advantages in fuel efficiency, range, and cargo capacity are often cited as reasons why you should buy from a particular Aerospace OEM.  How much does an extra pound of weight actually cost in Aerospace?

I’ve scoured the Internet looking for answers and I get a variety of inputs.  In general, an extra pound is viewed by the Aircraft OEM’s as costing a few hundred to a few thousand dollars.  For the Space industry, the cost of an extra pound can be several thousand dollars.

Unnecessary weight in a system does cost money.  It costs the manufacturer in higher material and transportation costs, it costs the customer in higher operating costs which is then passed onto the consumer in some form.   When you cut to the chase, when you competitor can offer a lower weight system with similar performance and cost, you will lose.  Boeing recently admitted that the first 787 planes will be “a little heavy”. 

Altair has established a reputation in the Aerospace market of reducing weight through the use of our OptiStruct software.  In fact, at many customers OptiStruct has become a verb – “have you Optistructed that part?”  Over the years, Altair has had several papers presented at our HyperWorks Technology Conferences that demonstrate how our customers have used OptiStruct to reduce the weight of their Aerospace systems.  You can view some of these presentations in the links below.  Unlike people, when you reduce a pound of weight here, it should stay off.
