Hiller designation list

- Model-1058 A tilt-duct design in a Hiller study for the Navy Bureau of Aeronautics which compared several VTOL and STOL concepts. Ultimately, the tilt-wing concept was confirmed as the most advantageous to develop and build. In 1956, a tilt-wing (the 1058??) was submitted in a competition held by the Office of Naval Research. It was defeated by Vertol's lower-cost aircraft.

What was this competition ?,which won by Vertol ?.
 
I think the Vertol concept is this one,V-90 ?.
Where did you get the notion that this photo represents the V-90?
I thought the same at some point, but I would like a reference for that, because I couldn't find any in my files.

I got it from Internet,but many sites are shut down now,but you are right and they
are wrong,here is the Vertol 90.

- Storc Another advanced look at logistical solutions was proposed in the STORC, a tip turbojet helicopter the rotor of which would be inverted and locked in position, transforming the aircraft - on the ground - into an airplane. Ferrying itself at high speed overseas to its operational theater, STORC would be free of ships and transport planes, and complexity of re-assembly. See image at top. Circa late 1950's/early 1960's (?).

Also may this STORC in a competition,we saw a similarity of it,could
be from Lockheed ?.
 
I meant a competitor from another company,I guess Lockheed.
Around the time of the Hiller STORC, Lockheed had indeed a Heavy Lift Helicopter, but it's drive was conventional turbine on the shaft and not turbine tipped on the blade. See the 1964 Aviation Magazine images published. I believe it was part of the CL-875 design series but not 100% sure.

The only one that comes close is the 10 years earlier Hughes XH-17/28 models which requires no introduction to this audience as we all know them well.

To me it looks rather like a direct competitor to the Sikorsky S-64B, also sometimes called the S-63.
