Wanted: Composite Aircraft Designer

[Foxxy]

I am looking to talk a project through with a good composite aircraft designer, that has the necessary tools to come up with a computer design and then a model etc.

Aircraft is a 2/4 seat a/c twin jet
prob williams/rolls, glass cockpit all that sort of stuff.

I would really appreciate your help, although i must stress a do not wish to throw a whole bucket load of cash at it.

All the best

I did a 1 day composites course at the ImechE last week to brush up my stressing and design skills.

It was profoundly depressing - there doesn't appear to be anybody with a good model to allow composite primary structure to be accurately modelled, and everybody is still forced into huge redundancy factors (currently I use 2.25, as compared to 1.5 for metal structures). The new fabrication techniques all seem to produce less strong structures than hand-layup, whilst their advocates wouldn't even venture that these techniques would increase consistency of manufacture enough to reduce the certification redundancy factors.

Having said that, I' am a composites fan and a CAA design signatory - but I wouldn't venture to computer model a new design with any great degree of confidence.

The best guys in the business I know are Slingsby, Angus Fleming at Aviation Enterprises, and Bill Brooks at Pegasus Aviation - it might be worth contacting them.

However, if you do want to do a computer analysis on a new design - you will have to throw a lot of cash at it.
