Various Sikorsky helicopter projects

armed CSAR. HH-3 ?

Interesting. These podded turrets were tested briefly by US Navy CSAR HH-3 Sea Kings, but ultimately not adopted.

Hi,

Great find! Thanks. I have always wondered why Sikorsky has never pursued a light helicopter. Not able to compete in a flush market?

Hard to break into a saturated market, unless you have something significantly better/different than whatever is there. Example: Tesla cars. Love them or hate them, they broke into the domestic car market and made pure EVs visible and viable. You'd need something that order of "better" to successfully break into the light helicopter market.

If the S97 has acceptable vibration characteristics, I could see it being wanted as an air ambulance. The extra speed is highly desirable from the medical POV.

Sikorsky designd a project from HH-3 (S-61) to resemble Mil Hind ?!.

That was for the National Training Center, like the VISMOD tanks built on M551 chassis.

Although I cannot be 100% positive it is a Sikorsky project, the following design appears amidst a 1990 series of Sikorsky-only photos and designs in the National Archives. Has anyone seen it before?

There was also this design, from the same artist "A. Whyte", which definitely looks like other Sikorsky ABCprojects we've seen before. Original image here: https://catalog.archives.gov/id/354533002

Whyte is/was Sikorsky "house" conceptual artist.

Thanks. I gathered that much after looking at more Sikorsky paintings.

Thanks, Robin. To think it was posted only last week and I hadn't seen it!

Okay, just to make it clear... This was NOT a real Sikorsky project! It appears alongside other Sikorsky images in the National Archives collections, and shows that engineers can also have a sense of humor!
( I wanted to post it in the "Aviation humor" thread, but because some people can't behave, it sadly has been closed... )

Andy worked down in PD and I liked to go down there and talk with him. He did the layout of the S-76, which I still consider the best looking helicopter ever. This is his book

It is too late to go w a fan-in-tail w all these uh-60s which will now be retained for some some tome?

Thank you Hesham, CARA is a favorite.

I recently came across this: its a light attack helicopter designed by Sikorsky for South Korea. During the 1990s, Sikorsky proposed a light attack helicopter design and produced mock-ups in response to South Korea’s light helicopter requirements. However, its design was not selected for the eventual light armed and civil helicopter program. South Korea ultimately chose the Eurocopter EC155 and developed into the KAI LAH-1 Miron, as the basis for a joint development program with Korea Aerospace Industries (KAI) and Airbus Helicopters.

Does anyone know if this ever earned a "S" number?
