Kaman K-... list

For all of you with an interest in Kaman helicopters, there is a list of K-... type numbers in “AEROPLANE Monthly” June 2006 (page 74/75). It begins with the K-6 and K-9 projects. The article also contains a nice picture of the K-16B, one of the more unusual Kaman concepts.

Hi boxkite.

If it is possible show us Kaman K-... list.

Yes, of course.

I'm looking for more details regarding the K-6.
I miss the K-820 "Sealite" in the list.

Further additions?

Hi,

I don't know K-820 Sealite helicopter ,except I see it in www.vrtulnik.cz/turbiny.htm
site.
anther two helicopter to Kaman:
K-244 :rotating-wing RPV.
k-894 Super tomahawk :developed from Seasprite helicopter.

K-140, with a striking resemblance to the Fairey Rotodyne and K-141
(From: BMP Vertical Take-off and Landing <VTOL> Aircraft, (Series of papers
... of a conference held on Dec. 10-12, 1962)

One must remember that Kaman had an agreement with Fairey to promote the Rotodyne to the US Marine Corps.
Had the Rotodyne been accepted into service by the USMC (the Sikorsky CH-53 Sea Stallion being the winner), Kaman would have produced it in the United States!

So this is probably the reason for the Kaman K-140 looking so much like the Fairey Rotodyne design.

Hi,

The K-820;in 1970 Kaman unveiled a full-size mock-up of its
proposed new advanced multi-mission helicopter,design called
K-820 Sealite,it was development of the Seasprite and Kaman
an entry in a USN design competition.It was to use the main
rotor blades,transmission,drive system,tail-rotor,tail-rotor gear
boxes of the SH-2D then in service,but would be 3ft shorter and
have 15in-wider cabin.The concept never proceeded beyond the
mock-up stage.
But I don't know what was the USN competition ?.

Hi,

by the way,the Kaman K-600 (HOK-1,HUK-1 and OH-43D)
was also called K-3,and the K-190B was a four seat version
of K-190A,single pilot and three seats.
In 1956 the USN issued a high demanding specification for a
fast amphibious utility helicopter,the comtenders were Kaman,
Bell,Sikorsky and Vertol,the Kaman won the contract but it
submitted two proposals,one single engined (K-20) and the
other had twin engined,I think it was K-19).

I don't know about the K-894 Super Tomahawk, but the original Tomahawk was a variant of the Seasprite, pitched to the US Army for the program which produced the Bell UH-1. Apparently, Kaman won the original competition, but Bell got the contract after Kennedy was assassinated, because Bell helicopters were manufactured in Texas, LBJ's home state.

Hi Jschmus,

please if you ask the Wikipedia you will find many sites
speak about it;

Hi,

K-747:the Kaman designed and began manufacturing the K-747
blade,the world's first production all-composite rotor blade for
the Bell AH-1 Cobra helicopter in 1976.

http://www.iasa.com.au/folders/Publications/pdf_library/ospreypdfs/The%20American%20Helicopter.pdf

A couple of documents entitled "List of Navy Aircraft Manuals in RG 287" mention a Kaman "K-255" helicopter and associate the designation "TD-31" to it... Any idea what this could be? A typo for K-225? Or a separate prototype? And what system would the "TD-" class belong to, since the Navy used this for Target Drones? A logical designation for a Kaman target drone should have been TDK, TD2K... not TD+numeral...

- Document 1

- Document 2

From the Bernard Lindenbaum Vertical Flight Research Collection:

K-15...............utility and liaison gyroplane proposal (1955)
K-120.............composite helicopter (1965)
K-190.............utility helicopter (1947)
K-800.............unidentified, undated proposal (brochure exists)

Please note that the Fairey Rotodyne as marketed by Kaman was simply called the Kaman Rotodyne.

K-800 was a project for an armed Navy helicopter with Seasprite fuselage, stub wings, pusher propeller, and twin-turboshaft engines. Possibly an entry to the LAMPS competition.

This is a bit off-topic, but I have seen video footage of the K-MAX being used as a UAV to move cargo in Afghanistan, with the unit VMU-1 apparently doing the work. At least two helicopters have been used, and at least one appears to have a U.S. insignia.

Does anyone know if a military designation has been applied to the K-MAX? I have found no record of one online to this point.

Where else can you see a photo Kaman K-1125 "Huskie III", I only saw three photos and one such

here two more photos to-1125 https://www.flickr.com/photos/28122377@N04/with/6083617408

Awesome gallery, thanks Mil!

Hi,


also the Kaman K-757 was a rotor blade;


http://www.dtic.mil/dtic/tr/fulltext/u2/a064159.pdf

Artist's concept shows Kaman K-800 Seacat armed helicopter, proposed to Navy as a high-speed aircraft for rescue and fire-support mrssions from seaboard. Helicopter uses many components of UH-2C. Air Force version would be called Firecat.

Hi,

the Kaman K-137 was a Radio-controlled drone based on the HH-43B.

https://sites.google.com/site/stingrayslistofrotorcraft/kaman-k-137

Just stmbled across this - the Kaman K-700

Proposed rescue helicopter for USAF based on K-1125 with two PT6A turboshafts, streamlined fuselage and large tail fin. Not built.

Intended as the ultimate H-43 design, the K-700's power would be derived from twin T-400-CP-400 turbo engines driv-ing the familiar intermeshing rotor blades. A stretched fuse-lage of nearly 12.5m would accommodate 14 passengers. Somewhat similar to the earlier proposed Huskie III, the K-700 was to have wheel landing gear, a "Vee" bullet-resistant windshield, self-sealing fuel tanks, provisions for external or internal auxiliary tanks, and an awesome array of armament, putting it on equal footing with contemporary gunships.

IMO the tail boom and fin look very flimsy for a combat exposed helicopter!

- To be continued

From this source,

and many clues that proofs Kaman made a various of credible
Projects,I make some speculations about Types K-7,K-10,K-11,
K-12 & K-13.

As I expected before,

the Kaman K-125,K-190,K-225 & K-240 were not their designations,but that
was their engine's power numbers,and they were gotten antoher sequences.
