Looking for info about Whirlwind-James Clavell

Hello,
I bought some time ago a James Clavell's Whirlwind cover but this one is
different of the Whirlwind book I have seen.
I would like to know if someone know about this book, publisher, year,
edition...
This is a beautiful cover drawn by the artist Sanjulian, it had a lot of
helicopters, the Khomeni face...

You can see at:

Thank you.
