Su-35S: News #2

This is the reality in many crashes of twin engine planes, the apparent redundancy frequently does not avoid the complications an engine failure implies.

Good that the pilot is ok, this should be among the first losses of that type of aircraft.

That may be true in a catastrophic failure, or low speed failure, but they do recover quite often on one engine. Also an engine can be shut down or reduced to idle if it is acting up, not an option on single engines.

seems like the plane continued to fly after he ejected. I wonder if he panicked.

That's pretty incredible that it flew for a little while with just one engine and no pilot. I would think that it would need quite a bit of stick and maybe even rudder input to maintain a relatively straight flight path with one engine torqueing the jet to one side. Maybe its in-flight computer senses all these things and automatically corrects the flight surfaces for a little while? Possibly goes into auto-pilot mode for a short time. Wonder how far that distance was from when he ejected to where it crashed?

There was a case during the cold war where a pilot ejected from a single engined fighter whose engine would not restart... after the pilot ejected however the engine restarted and the plane flew for more than 20 minutes and eventually crashed into a house killing a boy I seem to remember.

The Su-35S plane crashed into the Sea of Okhotsk in the Khabarovsk Territory as a result of engine failure during a training flight, the pilot ejected and survived. This was reported in the press service of the Eastern Military District.


"On July 31, 2021, an engine failure occurred on a Su-35S aircraft in the Khabarovsk Territory while performing scheduled training flights. The pilot ejected, was quickly found by the search team and taken to the home airfield. There is no threat to the pilot's health" – the report says.


The press service noted that according to preliminary data, the plane crashed in the Sea of Okhotsk.


"The investigation of the incident is conducted by the commission of the Eastern Military District" – the VVO stressed.

The search team found the wreckage

Good to hear they survived.

With K36s, I would be surprised if they wouldn't, chap.

He. Su-35S = one pilot.

yes, it was just before the end of Berlin Wall

MiG-23 flew without the pilot from Poland to Belgium, almost 1000 km !!!! That was the first unmanned plane

There was also an Egyptian Su-7 during the 6th October War of 1973, I can't remember exactly what happened but it was either shot by ground fire or a missile exploded near the aircraft but the engine temporarily flamed out and the pilot ejected only to see the Su-7 keep flying level until he lost sight of it. Later it had ran out of fuel and glided for a belly landing in the soft, desert sand. It was later photographed by the Israelis with hardly any damage it was amazing. I think it flew for a couple of hundred kilometers before running out of fuel. I used to have a pic of it but not anymore.

First unmanned plane flew back in the first world war.

Good stories with no deaths... it is just a plane and they can make more.

The source told the curious details of the fall of the Su-35 on Sakhalin

On July 31, 50 km from the urban-type settlement of Smirnykh, Sakhalin Region, a Su-35S fighter crashed. According to the press service of the Eastern Military District, the catastrophe occurred due to an aircraft engine failure. There were no casualties, the pilot successfully ejected and was taken to the airport.

A video of the search for the remains of a crashed flying machine has been circulated on social networks . In addition, one of the unofficial sources reported interesting and at the same time curious details of the fall of the fighter.

According to the source of the well-known blog BMPD , at the time of the pilot's ejection, the plane was absolutely serviceable. In the cockpit, the switch for shooting heat traps was incorrectly set - to the automatic position instead of the manual one. When the Su-35 took off from the runway, the blocking of the firing of cartridges was removed - due to the powerful radiation of the airfield radar stations, traps were released.

After firing the first cartridge, he ricocheted off the runway, creating an illusion of fire for the flight director - precipitation and morning haze obstructed visibility. Received a command to bailout. The pilot left the car, while the engines continued to operate in takeoff mode (afterburner). The pilot landed on the runway, the fighter climbed 13 thousand meters and after running out of fuel after 1 hour 13 minutes crashed to the ground on Sakhalin Island.

NOTE: here is the latest version of the crash cause. As per usual may not be the final one...

It's a twin engine that can fly with only one engine. It would be interesting to know what happened.

Did you not read the post above yours LSOS?

Or a better translation:

According to the source of the well-known blog BMPD , at the time of the pilot's ejection, the plane was absolutely serviceable. In the cockpit, the switch for releasing chaff and flares was incorrectly set - to the automatic position instead of the manual one. When the Su-35 took off from the runway, the chaff and flare launcher went weapons free, and due to local radar signals started launching flares and chaff bundles.

After firing the first flare and chaff bundle, which bounced off the runway, creating an illusion of fire for the flight director - precipitation and morning haze obstructed visibility. (so the visibility at the time which was effected by rain and early morning low sun angle conditions the guy inthe control tower mistook the flares for an engine fire and ordered the pilot to eject) Received a command to bailout. The pilot left the car, while the engines continued to operate in takeoff mode (afterburner). The pilot landed on the runway, the fighter climbed 13 thousand meters and after running out of fuel after 1 hour 13 minutes crashed to the ground on Sakhalin Island.

The engines were running fine and there was no fire so after the pilot left the aircraft the aircraft continued to climb to 13km altitude and flew for just over an hour before running out of fuel and crashing into an island.

So the aircraft took off in full AB and remained in full AB for 1 hour and 13 minutes... that is rather impressive... he must have been on a long range patrol or exercise with fuel tanks full..

Russian Knights are flying Su-35S' now, right?

They received about 8 Su-35s. But they also use Su-30SM

Outstanding.  They look great in their color scheme.

Display of the radar situation on the multifunctional display in the cockpit of the Su-35S. The mode of operation for ground targets. The range to the target is almost 120 km, and the altitude is 15210 m

Not just that, take-off thrust is more than normal 100%, normally only supposed to run it for tens of seconds at a time so it must have been fair belting along high supersonic for a lot of that.
Open cockpit would cause a bunch of extra drag so maybe topped out below normal top speed? But apparently not enough drag to lose control.

That's some great stuff!  Talk about well beyond visual range capability.  That bridge wouldn't know what hit it and how from that distance.  Love the part at the bottom where it says "ATAKA".  I guess that means a missile has been fired?

And a pic.

No, those squares around the entire display with what seem like capital Y characters in them are buttons and the white words around the perimeter of the screen are aligned with those buttons so if you count six buttons along from the left side of the bottom you get to the ATAKA button... presumably if you press that button the MFD switches to the ATAKA screen whatever that is.

Other screens include from left to right FON, NR, SR, VR, then nothing and then ATAKA and then MP, and then MOR, and then a gap and then SDTs, and then another gap and then TsEL or something I am not sure of...

The white box around the left hand bottom SO suggests this is the page/screen that is open at the moment.

Yes it was unmanned, albeit unintentionally. The performance of the autopilot, which engaged automatically, sensing lack of human input, and the altitude control system has been a case study in itself after the incident. The jet assumed a fixed vector it assigned for itself after the initial swaying from the loss of pilot and ejection seat weight and only veered to one side in its final leg of flight after the starving engine and subsequent fall of hydraulic pressure caused one control surface set to fail before the other. Otherwise it'd have gone straight to the English channel. The USSR paid some compensation to Belgium for the family of the victim and loss of property.
