Missile Projects / Re: Turkish Missile/Rocket Projects
« Last post by ocay on Yesterday at 02:10:31 pm »
Some air defence projects:

1. HISAR-A Short Range Air Defence Missile, around 15km range, IR Guided for Army
2. HISAR-O Medium Range Air Defence Missile, IR Guided, 25+ km Range for Army
3. HISAR-U Long Range Air Defence Missile, Radar Guided, Under Concept Design Phase
4. HISAR NOKTA, Air Force Derivative of HISAR to replace HAWK Missile
5. HISAR NAVAL, Navalised version of HISAR Missiles, probably RF  Guided
6. MANPADS, To be operational around 2017-2019 no infotmation available
7. SAPAN Air Defence Missile, A Navy Project, might be CIWS
8. Göktuğ Air to Air Missile, Turkish Medium Range Air to Air Missile, there are two version IR and Radar guided
9. Air to Surface Göktuğ, possible derivative of air-air missiles for Army and Naval use
10. ŞAHİN, A short range air-air missile probably similar to AIM-9X and ASRAAM

Previously Turkey locally produced Rapier Block-II missile and Stinger Block-I missile. Also developed various Stinger based VSHORAD Systems like ATILGAN-ZIPKIN-BORA..

ASELSAN also started to produce KORKUT SPAAG system, as well as NAVAL-CIWS derivative KORKUT-D

Duncanson patented his tubular spar system in 1928
Gloster High Speed Mail Carrier is in part 2 of an article "Folland's forgotten monoplanes" in The Aviation Historian, Issue 10

Thank you, that is most interesting. Vogt is said to have brewed up his system while on his flight back to Germany from Japan in 1933, to take up his new job at Hamburger Flugzeugbau. It sounds as if Duncanson beat him to it, not only in conception but also in first flight - the Ha 136 didn't fly until the Autumn of 1934, some months after the Segrave II.

I can't find any online info about the Gloster high speed mail plane project. Do you have a link by any chance?

Duncanson developed his tubular monospar system while employed by Goster and it featured in their High Speed Mail Carrier project in 1932. Unfortunately the poor financial state of Gloster led to many of the design staff quitting and Duncanson left to join Blackburn. After the spar was proven in the modified Seagrave it was developed further for the Blackburn HST10 transport. Unfortunately this failed to find a market and when Duncanson was killed in a car accident in 1936 his spar system was not taken further.
Thank you my dear Arjen.
As the French caption explains, the lower profile shows the Turbinlite-Havoc.
Text and first image from wiki:
The Helmore/GEC Turbinlite was a 2,700 million candela (2.7 Gcd) searchlight fitted in the nose of a number of British Douglas Havoc night fighters during the early part of the Second World War and around the time of The Blitz. The Havoc was guided to enemy aircraft by ground radar and its own radar. The searchlight would then be used to illuminate attacking enemy bombers for defending fighters accompanying the Havoc to shoot down. In practice the Turbinlite was not a success and the introduction of higher performance night fighters with their own radar meant they were withdrawn from service in early 1943.
The caption further mentions a 'Pandora' variant which would suspend a bomb on a line in front of approaching bombers. Blam - or so it was hoped.
Second image found here:
From Le Fana No.14,

a strange variant ?.

Great find my dear Sundog.
Ditto - amazing the number of iterations for this platform.

here is a drawing to tandem helicopter Project of 1906,for Henri Coanda;
