БРЭО бортовое радиоэлектронное оборудование |
17th February 2021: not all antennas I can identify, so You must expected corrections. There is very little information, but some indicates that the antennas are multifunctional and are used by different systems simultaneously. Even may they have the ability to focus on a selected direction. Probably system Н036Ш Покосник (N036Sh Pokosnik = Reaper) use some of these antennas and interrogators and transmitters), just like use N036L antennas. Obviously, ther is only a few antennas (or rather antenna's covers) on airplane, so we must suppose that antennas are multifunctional or integrated. Even Flight Control System airprobes are reduced to minimum - we don't see old-style probes of angle-of-attack, pressure etc. |

It's a single* unit located in right engine compartement, to simplified construction and maintenance of aircraft, mounted on ВКА Выносная коробка приводов самолетных агрегатов [VKA external accessory gearbox]. On the ground APU supply compressed air (0,55 kg/sec) and up to 30 kVA energy to plane systems. In flight mode ЭНЕРГОУЗЕЛ [energy knot] produce electricity (16 kVA) to air-conditioning systems of cabin and produce 115/200 V AC to onboard networks. Important is that one APU can start both engines. * According to 2018 Lyulka OKB booklet. | |||||||||

Air intake |
The supersonic air intake has an adjustable cross section - this is done by two movable plates (ramps, panels - whatever you want to call it) on the top wall, that can be lowered synchronously. When the aircraft is flying at supersonic speed, they cause the air in the back of the diffuser to still have subsonic speed. To ensure that the air entering the engine has a linear flow and not turbulent, the boundary layer is extracted through several perforations on inner walls of the air intake. Then is collected and discharged outside the aircraft through perforations or holes covered with mesh on outer walls. At the bottom of the air intake there is a additive air intake (on firsts prototypes it was a couple of blinds). |
ECS Environmental control system provides among others: air supply, thermal control of the cabin and equipment bays, avionics cooling, smoke detection, fire suppression. It's a pretty sophisticated system which include primary and secondary heat exchangers, valves, cooling air cycle machine, compressor and other components. Air inlets are located in pylons of the vertical stabilisers. In the right for secondary heat exchanger, almost certainly air-to-air radiator (ВВР Воздухо-воздушный радиатор), in left maybe for primery heat-exchanger (maybe ТВР топливно-воздушный радиатор fuel-air radiator). Components of ACS air conditioning system (СКВ Система кондиционирования воздуха) are located in two compartments on top of fuselage. Only left has a rhombic-shaped hole for air exchange, covered with mesh. When aircraft is on the ground, probably hot air for conditioning system is taken from compressor of the auxiliary power unit (very hot bleed air). 14th March 2021: some details are hipothetical, based on Sukhoi Company patents, but explained on real aircraft photos... |
