I have developed similar material spar structure for a wind turbine ( VAWT ) . I wonder if the Napier-Heston plans are still somewhere ?

If memory serves me correctly, Tim Moore of Skysport, was looking into building a replica, but unfortunately, he couldn't find anyone to fund the build.

Great info Bob T,

If Tim Moore is reading this ( or reachable via you ) tell him that I have managed to produce 1400 kg/m3 dense wood composite with fairly simple method ( 2015-2017 ). Wood composite is lot stronger than aluminium...and some even as strong as steel...and 1/6th of the weight.

Wood has been used as a composite in motorsport for many years - the trade name 'Mallite' was used in a number of moncoque applications in the same way as it was on the DH Mosquito.

Mallite and Dh Mosquito composite is different..those are not compressed in high heat. Howard Hughes did use some compression in the HK-1 birch wood sheets. It was called Duramold; https://www.buildtheenterprise.org/the-spruce-goose-a-modern-composite-aircraft/

Aren't Jablo propeller blades an example of this type of technology?

These are similar yes...and relatively easy to make in a mold ( I assume ); https://www.mt-propeller.com/en/entw/pro_blades.htm

Also the newly restored Twin Mustang has those !

Usually word compreg is mentioned if it is compressed instead of just laminated.

Compreg comes from impregnated and compressed; https://www.jstor.org/stable/44467948?seq=1#page_scan_tab_contents

So is anyone interested to buy this wood composite ( 30 X stronger than wood ) that enables you to build a wing ( spars for instance ) thin like in F-104 and stealthy like in Horten H-229 and superlite like in Libelulla ?

It was used in Heston J-5 and HK-1, but is twice as strong now.

The problem is that I don't actually have a product to sell.

But if there was interest just maybe I could start a company that could start to produce this stuff.

I refrase my question ( if you don't mind ); Do you ( a reader ) have a certain itch to get a better aviation "lumber" that is available today ?
