Hi,

in Flightglobal site I read about the Lockheed CL-379 tilt-wing research
aircraft project,which was selected from more than 30 design-studies,
and more Info or drawings,please.

Here's an artists impression of the CL-379 "in action":
(from FlugWelt 1959)

And it's cheap!
 
umm how can it stand on the ground with props forward as they touch the ground? Something's wrong.
 
looks like the wing tilts. It probably can't have the wing in the horizontal position while on the ground for the reason you mentioned.
 
The same principle obviously found favour again in a Saro project from
1967, the Saro P.5.39, although here ground clearance would have been
sufficient to allow for take-off with the wing not tilted. Question to me is,
would it really have been a VTOL, or just an ultra-STOL ? AFAIK, prototypes
actually built using this principle (Fairchild Fledgeling, Ryan Vertiplane) never
achieved true VTOL

You can probably achieve takeoff within a fuselage length (I think this was quoted for the VZ-3), but no VTOL
