That image corresponds one of the not built variants of the XH-59.
Here an outline of the possible developments of the XH-59 proposed by Sikorsky and that they would share the same group propeller.

Here is a picture showed CARA of US.
The VTOL aircraft fitted with retractable Roto on dalso and tail for VTOL, while needing level fly, the roto will autometically retracte and stored in airframe for reducing drag. The power mianly rely on one Jet and fan engine each side.

Here the S-57 looks more then a "flying pancake", than as a delta, as it was shown
for example in FlugWelt I/60 :
Nevertheless an interesting design ! Slightly OT, was their ever a single blade rotorcraft,
that actually took to the air ?

Couldn't find any other drawings of this design, so I had a quick attempt for
a simple drawing on my own. Problem, due to lack of sufficient informations
is the fuselage width and shape, I used the XH-59 and S-72 as a pattern.
So, careful please, speculative guesswork only !
I've attached the cdr-file (zipped), too, so those of you, who have CorelDraw,
or another software, that can handle such files, can make corrections on their
own ! ;)

Excellent work!! Just what I needed. What size did you use? I have calculated the main rotor of the "CH-44B" from the earlier posted link as being about 17 meters (56 ft) in diamater (this based on the size of the Marine at the rear of the rotorcraft.

Assuming that the drawings of the ABC concepts are at least roughly to the
same scale, the fuselage length would be nearly identical to the XH-59A,
that means 40' 9" ( 12,4m ). Rotor diameter seems to be larger, around 40' 8"
( 13,6m ), compared to 36' ( 11m) for the XH-59.

A couple of unidentified projects from RAF Flight Revue 1962 issue.
You mean "RAF Flying Review", right? ;)

Pome, the lower aircraft is your posted image appears to be a modified Grumman Mohawk, or at least to use the fuselage and tail of one...


cheers,
Robin.

Hi,
from Sikorskyarchives,you can find a group of V/STOL and VTOL aircraft,some are
known for us and some are new
.
Please define "us". All these designs have been seen before as far as I'm concerned.

You don't have to feel obliged to include others in your posts. Saying "Some of these designs are new to me" is enough...
