Talk:SNCASO Trident

Number built?
From what I can work out there were two SO.9000s built, of the 10 SO.9050s ordered only six appear to have been built. Perhaps someone can confirm this, thanks. Nimbus (Cumulus nimbus floats by)    13:55, 7 April 2010 (UTC)

Wing area
There's a very different number (99 sq ft) in the 1957 Observer's Book of Aircraft, which agrees on all the other imperial dimensions. Green and Cross, in Jet Aircraft of the World 1955, agree with OBA. So 156 sq ft may not be right, but a quick measure of the g/a drawing suggests a little over 145 sq ft, in broad agreement with the bigger number.TSRL (talk) 20:32, 7 April 2010 (UTC) Thes numbers are all for the Trident I.TSRL (talk) 20:50, 7 April 2010 (UTC)


 * Just to confuse things more, the Complete Book of Fighters by Green and Swanborough has a wing area of 178 sq ft for the SO 9000 Trident and 156 sq ft for the SO 9050 Trident II! Nigel Ish (talk) 20:37, 7 April 2010 (UTC)


 * I did spot something amiss there as well, my Jane's experimental aircraft book gives 99.03 sq ft (9,2 sq m). From memory the F-104 is 22 ft span (same as the Trident not counting the engines) and has a wing area of 196 sq ft. Gunston says 156 sq ft for the Trident. Will have a look if there is any consistency in the other language articles. Perhaps it is just one wing?!! Nimbus (Cumulus nimbus floats by)    20:54, 7 April 2010 (UTC)


 * The other language articles all have different wing areas!! Did the Trident I and II have different wing spans? Bit of a mystery. Nimbus (Cumulus nimbus floats by)    20:58, 7 April 2010 (UTC)


 * According to Complete Fighters, both a shorter span and reduced chord.Nigel Ish (talk) 21:17, 7 April 2010 (UTC)


 * JAWA 56/7 gives a shorter span of 7.50 m (or 7.52 m if their imp 24' 8" is right (!)); they say it's the same for both Trident I and Trident II. BTW, the F 104 wing is quite different in plan at least, with marked taper.TSRL (talk) 21:34, 7 April 2010 (UTC)


 * Complete Fighters has a span of 7.57 m (24 ft 10) for the Trident I and 6.95 m (22 ft 9⅔ in for the Trident II.Nigel Ish (talk) 21:38, 7 April 2010 (UTC)

Engines
According to JAWA 1956/7, the Trident II rocket engine had four chambers, not two. OBA 1957 does say two, though.TSRL (talk) 20:59, 7 April 2010 (UTC)


 * There are some specs in the French external link, shows different wing spans and areas, seems to say that the early rocket motors had three chambers and the later ones had two (agrees with Gunston). Also notes the three different turbojets (Marbore, Dassault Viper and Gabizo) and a Trident III and IIIC variant. All good stuff. Nimbus (Cumulus nimbus floats by)    21:22, 7 April 2010 (UTC)
