The whole interstage (a/k/a transfer compartment) issue is new to me; apparently, the interstage is the responsibility of either the payload provider or the upper stage provider. So, RSC Energia seems to provide the transfer compartment for Progress and Soyuz, whereas Lavochkin handles the interstage for launches using Fregat, and TsSKB for launches using their payloads.It would be interesting to see the index numbers for the interstages, and also if there are any other providers besides those mentioned above.
Now to launch Resurs-P № 2 on a Soyuz, it was decided to use the larger 81КС fairing. As that launch did not require a Fregat, which would have come with a PKhO, RKTs-Progress supplied one instead. It was referred to as 196КС.
It is possible 196КС is a complete SZB too; it includes an 81КС GO.http://novosti-kosmonavtiki.ru/forum/messages/forum14/topic12755/message1316921/#message1316921I think 81КС is just the GO.
По Договору застраховано следующее имущество: Головной обтекатель 81 КС (ГО 48/134) и Переходный отсек 196КС (ПхО 48/134) для КА "Ресурс-П" №2. (далее по тексту ГО 48/134 и ПхО 48/134 -"Груз") .
Which is the pipe? Are those things wrapped in silver plastic telemetry antennas?
Not the best thread for this, but I didn't want to necrobump. How can the baikonour range support launches by two different vehicle types on consecutive days?
