Piasecki / Vertol / Boeing Helicopters model numbers

[hesham]

we know Boeing-Vertol BV series (BV-107,114,143,145,147,165,
173,176,179,219,227,234,237,298,299,301,307,308,309,347,352,
360 and 414),and I am asking are there anther projects to this company?.

 

[boxkite]

A few Boeing Vertol additions:

76 (designation of Vertol 76 since 1960)
105 (mentioned in “aero” June 1959, no details – misprint?)
137 (tilt-wing transport, Tri-Service competitor)
189 (no details)

 

[hesham]

Yes boxkite,

but the models 59,63,71,76 and 105 were to Vertol only.
Boeing-Vertol -222 :tilt-prop project using the fuselage,tail,and undercarriage
of Mitsubishi Mu-2J,engines in wing tip,project not built.

do you have information about Boeing model-858 helicopter?.

 

[hesham]

Thanks my dear Jemiba,

for dear boxkite,some Vertol helicopters:
V.63 HUP-4 :was HUP-2 (PV-18) fitted with an 800 hp R-1820 engine.
V.71 (H-21D) :two H-21C re-engined with G.E. T58 turboshafts engines.
V.76 :was VZ-2 to the Army (well known).
V.105 :was Model-44 fitted with two 825 hp Lycoming T-53 turboshafts,
prototype only.

 

[elmayerle]

..and some more:

- model 301 flying crane
- tilt wing for 90 passengers
- Rotafix, with two single bladed rotors
- and the model 222, mentioned by Hesham

From what I've read elsewhere and the picture here, the Model 222 appears to use the long version of the MU-2 fuselage and tail. That would certainly simplify trying to model such.

It actually makes a lot of sense because the wing on the MU-2 is a one-piece wing that can be replaced without disturbing a lot of the aircraft systems.

 

[Stargazer2006]

The two giants Bell and Sikorsky often make people forget about the third large company that made the helicopter a reality back in the late 1940s: P.V. Engineering Forum, later known as Piasecki Helicopters and then Piasecki Vertol. The company's assets were purchased by Boeing in the late 1950s, and though it now carried the name Boeing Vertol, the model numbering system carried on from where Piasecki had left off.

Frank Piasecki then set up a new business under his own name and came up with the Model 16-H PATHFINDER helicopter, which unfortunately failed to attract customers. Today his name and vision are being avenged as the name Piasecki is once again, half a century after takeover by Boeing, back in the military procurement business for a SPEEDHAWK conversion of a UH-60 designated X-49A.

Here is a list of model numbers. The former part of the list deals with Piasecki models. The latter part presents the Boeing Vertol models.

Hi,

for Vertol PV.63 and V.105,I spoke about them and my dears Boxkite and
Jemiba spoke about PV.119 here;
http://www.secretprojects.co.uk/forum/index.php/topic,1010.15.html
and about PV.11 and PV.12 please see;
http://www.secretprojects.co.uk/forum/index.php/topic,898.msg8106/highlight,vertol+pv+11.html#msg8106

 

[Stargazer2006]

Thanks for the additions. I've also added a couple more things on the side from the links you provided.

 

[Stargazer2006]

A Wichita State University listing found on the web mentions a Vertol Model 90, stating that a 15% wind tunnel model was tested.

http://specialcollections.wichita.edu/collections/university_archives/record_groups/finding_aids/pdf/06-12-00-05.pdf

Another Vertol program I can find no designation for is this early tilt-wing six-prop sub-scale demonstrator. It carries the U.S. Army and N.A.S.A. logos, but I have never been able to properly identify it. I enclose a photo hoping someone may come up with some clues...

 

[hesham]

Hi,

the BV.143 was ACH-47A,an armed enemy suppression Chinook with
externally mounted 20mm cannon,nose turret with grenade launcher
and miniguns.
The BV.145 was CH-47D with T55-L-712 engines.

 

[Tailspin Turtle]

The 222 was a tilt-rotor, not a tilt-prop. It was proposed in the NASA competition that resulted in the XV-15.

 

[Stargazer2006]

Thanks! I've updated the list.

 

[Stargazer2006]

A very interesting list of all the Chinook-related model numbers directly for Aerofax Minigraph #27:

One small correction, it's Wichita State University, not University of Wichita. *chuckle* I should know as I did graduate work there (but for getting laid off by Learjet in the summer of 1982 and moving to California, I probably would've gotten my MSAE there).

 

[Stargazer2006]

Thanks, I've corrected the mistake!

[hesham]

Hi,

PA.101 was the Piasecki (PiAC) designation for sales and
manufacturing rights to the Agusta A.101G transport
helicopter in USA.

 

[hesham]

Very strange,

in the DTIC report which was discovered by the member
Triton;
http://www.dtic.mil/cgi-bin/GetTRDoc?AD=ADA085290&Location=U2&doc=GetTRDoc.pdf

about the Boeing Vertol HLH helicopter,they wrote
that;the report number D301-10323-1,and in that report
you will find the Model-301 as the meaning of D301,but
in the two NASA reports which I discovered them about
the same company we will find that;

1-Report No or number D210-10873-1
2-Report No or number D238-10000-3

And we refused to call them Model-210 and Model-238,
why,give me a good reason for all and not only for the last
two reports.

http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19750022072_1975022072.pdf
http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19770010060_1977010060.pdf

 

[Stargazer2006]

And we refused to called them Model-210 and Model-238,
why,give me a good reason for all and not only for the last
two reports.

First of all, I don't think anybody here REFUSED to call any design anything... I have no problems with D210 and D238 meaning D-210 and D-238 if the rest of the clues are consistent (dates, etc.). All that I and other members said was that we must be cautious with drawing hasty conclusions as you often do. I myself resort to the same kind of deductions as you do but I don't assert them as fact, and most of the time I only write about them when they are confirmed.

Secondly, your use of the word "Model" is definitely wrong. The "D-" series applies to designs, not models. The model numbers constitute a separate numeral list from the D- numbers.

 

[hesham]

Hi,

a reference to Boeing Vertol Model 170-544P V/STOL aircraft
is here;
http://www.dtic.mil/cgi-bin/GetTRDoc?AD=ADA088833&Location=U2&doc=GetTRDoc.pdf

with two unidentified drawings.

 

[Stargazer2006]

Interesting find, hesham, but I'd be cautious before drawing that conclusion about this design. Indeed, the brochure is about a program called VASCOMP II (V/STOL Aircraft Sizing and Performance Computer Program II), and the image is simply what the caption says: "Typical Aircraft Geometry", serving as a generic reference for what V/STOL aircraft should look like. The manual contains only this aircraft illustration, the rest is full of technical computing diagrams. Now maybe Model 170 was allocated to that generic study model, maybe not. I don't think we have enough elements here to decide that the image is it, though.

 

[hesham]

http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19770010060_1977010060.pdf

That again,I think I was right;


in DTIC document,we find this reference;


4- Investigation of the Performance of Low Disc Loading Tilt Rotors in Hovering and
Cruise Flights. (NASA Contract NAS2-5025) Boeing-Vertol Division Report
D160-10013-1, March 1971.


and we find again the report D160-10013-1 means Model-160 as we know it here;
http://www.secretprojects.co.uk/forum/index.php/topic,7005.msg128188.html#msg128188


so I think that;


D210 means Model-210
D238 means Model-238


and we consider also;


D180 means Model-180


the source for my evidence ;


http://www.dtic.mil/dtic/tr/fulltext/u2/757267.pdf

 

[Stargazer2006]

I think we need more evidence before we can jump to such conclusions. Please be careful, you have made mistakes in the past (and so have I) trying to find logic in report numbers, so let's not turn hypotheses into false certainties.

 

[hesham]

No,


I didn't mean this,but my theory is; the first number allocates for Designation
and the second number allocates to report number.

 

[hesham]

Hi,


the third evidence,in two NASA reports,there is the same conclusion,
D222-10062-1 was also called Boeing-Vertol Model-222,and the second number
was for report.


Also in the second report,D222-10060-1,was also Boeing Vertol Model-222
and the second number was for the report,but there is many reports,so
one called 10062-1 and the second called 10060-1.


And D222 meant Model-222.

NOTES:
- Some of these designations carry the prefix BV- while in others it was omitted.
- The hypothetical ones are derived from the report numbers which are preceded by the letter D (e.g. D180, D210).
- Not all D* report numbers concern aircraft or helicopters, which leads one to think that probably NOT all BV- numbers exist, only those where a study becomes a true project.

 

[hesham]

Also;


238 was tilt-rotor aircraft project.


http://www.secretprojects.co.uk/forum/index.php/topic,5301.15.html

PV-45 was XH-27 designation as in;

with two unidentified drawings.

Anther evidence for D and a number after it,was the design number;


a reference D170-10039-1 means Model-170 as in the same source;
http://www.dtic.mil/dtic/tr/fulltext/u2/734236.pdf


The Model-170 was a tilt-wing V/STOL aircraft.

 

[hesham]

I found this report from DTIC,spoke about Boeing Vertol SK142,
and may be (only my suggesting),it was Model 142;
http://www.dtic.mil/dtic/tr/fulltext/u2/622586.pdf


And as you see in Boeing Verol Model 215 report,they wrote on
the drawing SK215 also;

Hi,

the BV.177 was accommodated 94-seat.

 

[boxkite]

...

Here is a list of model numbers. The former part of the list deals with Piasecki models...

...
PH-/PV-42 USAF H-21A WORKHORSE military transport helicopter (AV 166)

Checking old issues of the American Helicopter Magazine (thanks to @vstol ), I found these pictures in # 8/1955 (p13), labelled as Piasecki PH-42 (= commercial version of H-21).

 

[hesham]

Nice find my dear Boxkite.
