Hi Maveric!

Model 1098---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.
Hiller Model 1067 (transport/rescue)
Hiller Model 1084 (multipurpose-transport)

... these proposals based on the X-18.

SOURCE: X-Planes by Jay Miller (1st edition, page 140)


Hiller Model 720 (combination of two Model 360)
Hiller Model 1005 (crane helicopter)
Hiller Model 1059 (deflected slipstream STOL aircraft)

SOURCE: One Way Up by John F Straubel

Of course, all of them were unbuilt projects ...
Thanks boxkite and nugo...

...any drawing and technical data?

To get an impression of the Model 720 ...

found only Model 1091 (CAMEL), without any details ???

Servus Maveric

the Model-1048 was based on X-18 as civil transport aircraft project.
Please read the remark by Andreas Parsch...
My dear lark,

the source is the X planes X-1 to X-29,by Jay Miller (book).

1108 was tip turbojet-powered very heavy-lift helicopter.

NOTE: a page of this forum shows a flying crane model "to perform midair recovery of the first stage of the Saturn 5" which is given erroneously as the Model 1045.

*asterisk indicates projects identified as Fairchild-Hiller
My dear Stargazer2006,

I suggest that the Fairchild-Pilatus PC-6 Porter was the design FH-1117.
Thanks, hesham! Any document or link to back up that piece of information?
My dear Stargazer2006,

I think that report spoke about many little known aircraft and projects,
they mentioned the Hiller Model-1117,so I suggest only it was Fairchild-
Pilatus PC-6,and I am not sure.
Ok, then I already had that source and didn't know what to make of it. Perhaps allocating this to the Pilatus Porter is jumping to conclusions a bit too fast... I'll continue to investigate the matter, anyway. I'll also update the Hiller list a second time soon, there's a lot more to that name than the UH-12 series!
My Hiller list on page one has been updated.

Here is a list of as yet undesignated Hiller projects (photos provided when *):

- "FLYING SHOES", the first Zimmerman flying platform*
- Hiller autogyro*
- BARC (Besson's Aerial Railhead Crane)
- SKYBUS, a large forty-to-fifty passenger civil ram jet transport helicopter project*
- mixed-propulsion aircraft project, apparently for COIN missions* (perhaps same as Model 1059?)
- shrouded rotor VTOL proposal*
- transonic VTOL project*
- FLYING JEEP four-duct proposal for Army*
- AERIAL SEDAN four-duct personal flying car project*

Not a single forum member to identify the above designs more accurately? Ah well...

An addition to the list: Model 1051 is given as the X-18 PROPELLOPLANE, although this already appears as Model 1085. The difference between the two is unknown to me, though I can speculate the former may be the paper project while the latter was the finished product.

Concerning Model 1117, it is mentioned as a "rotorcraft", so it's definitely NOT the PC-6 Porter.
From the Bernard Lindenbaum Vertical Flight Research Collection:

1031-B............variant of PAWNEE flying platform, no details [possibly the later deep-duct version] (1957)
1051...............initial designation of X-18 [System 451L]; became Model 1085 after modifications [System 607A]
1069...............rotor-prop convertiplane project
1082...............Multi-Purpose Turbine Powered Helicopter proposal (1958)
1099A.............TEN99A Missile Site Support Helicopter proposal to USAF (1962)
1117...............Light Armed Reconnaissance V/STOL Aircraft (1964)
Hiller ad with small drawings of models 1048, 1067 and 1084.
Also an ad for a large heavy lift helicopter, don't designation or if this design has been posted before.

It's Model-1108 as I think.

No, it's actually the Model 1089, proposed circa 1961. Do you have the date of publication of the second ad, RAP?

The FH-1108 was a 1964 derivative of it, apparently a Hiller-Continental project for a tip turbojet-powered very heavy-lift helicopter.

Hi guys. I would like to scratch the subject of Model 1100 a bit. I dig out its FAA type certificate (>>H2WE<<) and there is clear distinction of models as follows:
  • Model 1000: 4 person helicopter powered by Allison 250-C10
    • also kind of includes US Army OH-5A (engine named as T63-A-5)
  • Model FH-1100: 5 person helicopter powered by Allison 250-C18 or Allison Model 250-C20B (after certain mod.)
Interesting is Note 5: If I am understanding it correctly, it says that Model 1100 as an ARMY OH-5A is actually bit different, and could be converted later to the certified state.

So, for me, there were three different variants: OH-5A, Model 1100 and Model FH1100.

I guess that model 1100 was still envisioned before Hiller was taken over by the Fairchild - that happened on May 7th, 1964, and the type certificate was granted on May 22nd, 1964 - clearly it was process of at least dozen of months of duration at that time.

Then, following this line of thought, the FH-1100 was a Fairchild's push to increase its performance (one more person on board).

Now I am trying to identify those variants on pictures. It is easy for FH-1100 - as several of them were built. Also well known is form of the OH-5A (or rather YOH-5A), as it is documented on pictures from its Army trials. Problem is with the Model 1100 as a civilian helicopter. So far I found one picture most likely showing that model, but described as FH-1100. Yet another picture clearly shows similar (or very same) helicopter, just with slightly modified cowling and writing FH1100 on it (although it is S/N 2).

I compiled a little chart with visual differences per variant as I perceive it right now (attached).

Am I right?

The French Aviation Magazine briefly mentions the 1098 again in 1963. Or maybe this is not even the 1098. Hiller was really designing a lot of models at the time
