Talk:Sikorsky H-5

H-5?
Wondering what the reference is for the R-5 being designated as H-5? The only H-5 I can find recorded is the YOH-5. --04:07, 1 January 2007 (UTC)

I too thought this was odd. H-5 is the British name, yet it was a American design, and mostly sold to the American military as the R-5 Larek (talk) 17:02, 20 January 2012 (UTC)
 * Nothing to do with the British the H-5 was the American designation from 1948 onwards when all surviving R-5 aircraft were changed to H-5. MilborneOne (talk) 17:07, 20 January 2012 (UTC)
 * And I have reverted the move as clearly H-5 was the US designation which is all explained in the article, you will need to start a move request. MilborneOne (talk) 17:12, 20 January 2012 (UTC)
 * Only after 1947, R-5 is the common name, example United States Army Aviation Museum calls theirs a R-5, and current hits on google 'Sikorsky "R-5"' is 311K where 'Sikorsky "H-5"'is less at 278k, that alone should justify the original name.Larek (talk) 17:34, 20 January 2012 (UTC)
 * As the move due to it being a British name has been challenged you still need to gain a consensus for a move. MilborneOne (talk) 17:38, 20 January 2012 (UTC)
 * Just out of interest the United States Army Aviation Museum also has a H-5 . MilborneOne (talk) 17:49, 20 January 2012 (UTC)
 * As the move due to it being a British name has been challenged you still need to gain a consensus for a move. MilborneOne (talk) 17:38, 20 January 2012 (UTC)
 * Yes I admit to being wrong on the British bit, however I still think the move is justified, and as for consensus, isn't it currently 2 (me and '07) to 1 (MilborneOne)?
 * And There is constancy, both the R-4 and R-6 are named R-# even though R-6's re later renamed H-6
 * And The Museums listed call it a R-5 or the specific variant name like YR-5A or S-51, None on the list have a "H-6" on their wiki pages
 * And The Google count.... Which now says 810k for H-6 ???? I now lose this point Larek (talk) 18:11, 20 January 2012 (UTC)
 * You are correct on the United States Army Aviation Museum, good catch Larek (talk) 18:11, 20 January 2012 (UTC)


 * Keep at H-5; the R-4 and R-6 are at R-4 and R-6 because both models primarily served in the 'R'-designated period before 1948, whereas the R-5/H-5 is best known for its Korean War service, at which time it was H- designated. - The Bushranger One ping only 23:47, 20 January 2012 (UTC)


 * IIRC, the 'R' originally stood for 'rotary' winged as the helicopter had not been around long enough to warrant a separate category at the time. Previous 'R' aircraft had been autogyros such as the Kellett KD-1. Later the 'H' helicopter category was introduced, at which point the designations were changed for helicopter types already in existence. — Preceding unsigned comment added by 80.7.147.13 (talk) 09:37, 20 September 2013 (UTC)

Needs clearer distinction of original S-48 models from later S-51 models.
The original versions of the R-5, including the YR-5A, R-5A, R-5D, and HO2S-1, all came from Sikorsky's S-48 model, while the later S-51 model was the basis for the H-5F, H-5G, H-5H, and HO3S-1. There are distinct differences between these two models, the most obvious of which is the landing gear configuration: two forward wheels and a tail wheel on the S-48 models (with a small nose wheel added to the R-5D) versus two rear wheels and a nose wheel on the S-51 models. The window layout is also distinctly different between the two models. You can see the difference if you compare the infobox picture (a YR-5A at the USAF museum) with the other pictures in the article. I'll try to make the distinction a bit clearer in the article. --Colin Douglas Howell (talk) 19:27, 26 July 2016 (UTC)
 * OK, I think I've managed to better distinguish the S-48 versions from the S-51 versions. --Colin Douglas Howell (talk) 08:52, 27 July 2016 (UTC)

Carry me
Okay, the H-5 had greater payload capacity than the R-4. What was it? Since neither this page, nor the R-4 page, ever mentions it for either of them. TREKphiler any time you're ready, Uhura  02:55, 12 January 2019 (UTC)
 * Jane's All the World's Aircraft 1951/52 gives a "disposable load" of 1505 lb for an S-51 with composite, 58 ft diameter rotor blades, or 1695 lb with all metal blades (59 foot diameter) - the empty and loaded weights don't quite line up with those currently quoted in the specifications, although the 58 ft rotor diameter suggests composite blades.Nigel Ish (talk) 11:00, 12 January 2019 (UTC)
 * Thx. That looks like fuel, stores, & all. Polmar's Military Helicopters of the World (my go-to, because I have it ;p ) doesn't say anything... :(  TREKphiler  any time you're ready, Uhura  17:16, 12 January 2019 (UTC)
