What is the long thing that sticks out between the Su-35's jet exhaust nozzles and what does it do?

The long thing has RWR (Radar warning Reciever) on its sides and has a drogue parachute in the middle. This image shows the rear part open after deployment.

Incidentally, the aircraft serial number is 901, while the one in your image has a number 902.

  • Does the Radar warning Reciever do the same job that Hawker Siddeley Nimrod tails, with electronic warfare (ESM) sensors, do? – Revolucion for Monica Nov 03 '16 at 20:00
  • @Marine1 the Nimrods tail is a Magnetic Anomaly Detector, designed to detect a submerged submarine as the aircraft flies over it - its positioned in such a way because it has to be clear of the aircrafts magnetic field distortions. The RWR on SU-35 and other aircraft merely detect when the aircraft is being hit by radar. – Moo Nov 05 '16 at 10:52

If you are speaking of the grey volume, according to this cutaway by Alexey Mikheyev, it contains a Radar Warning Receiver/Electronic Intelligence System. Basically a system designed to detect if an hostile weapon system is locking/has locked on you.

    You have copied the cutaway from its source to Stack Exchange's imgur.com server. It would be best to provide attribution of the source for the image in your answer. In addition, if the cutaway has a license that makes it reasonable to put on Stack Exchange's imgur.com server to share in your Answer, then the answer would be better if you display the image in your answer rather than just link to it. – Makyen Nov 02 '16 at 14:52
  • @Makyen I agree, but none of this was available. The image was on pinterest with no attributable source except the one in the top left corner of the image (that I left untouched). If you have found any linkable source I will be happy to include it. – Federico Nov 02 '16 at 15:08
  • Then it would be better to have the link in your question be to the source, rather than a copy. Moving a copy to Stack Exchange's imgur.com server introduces copyright issues to your question. Having, instead, a link to the page where you found the image leaves the copyright issues on that site. – Makyen Nov 02 '16 at 15:17
  • @Makyen but in turn not copying to imgur introduces the problem that the link might go dead. – Federico Nov 02 '16 at 15:26

    That is one of the risks of complying with copyright. You can mitigate this risk by finding an archive of the site, or having an archiving site create an archive. – Makyen Nov 02 '16 at 15:32
  • @Mayken we've discussed in chat. The outcome is that, as the author does not seem to have a website we can direct to, and his name is in the image, pointing to random 3rd party websites would not help him. I will report his name in the post. – Federico Nov 02 '16 at 19:00
