How do they work (Russian aircraft)

[X-man]

It uses the same system as F-22 and the Rhino. Much more effective then the dorsal speed brake.

[robmlufc]

I guess the duct above the left engine could be the apu intake and the duct above the right engine could be the API exhaust? Or the other way round!

[JLZ]

Here is another cutout of Su-27

 

 

On MiG-29 APU exhaust was located ventral. Because of that, external tank have had hole to enable APU to exhaust right through it.

 

On 29K it was located dorsal to lower fire hazard and allow bigger external tank.

 

On the ground the engines can be started singly or simultaneously by means of an NPP Klimov (Izotov) GTDE-117 auxiliary power unit located in a bay in the aft fuselage between the engine nacelles. The APU's 'elephant's ear' air intake offset to port on most versions (or to starboard on the MiG-29K/MiG-29M), is located at frame 7; the exhaust is located on the fuselage underside near the starboard nacelle and closed by a door to reduce drag when the APU is off. In flight the engines are restarted by windmilling at speeds down to 300 km/h (186 mph).

Maybe it's also for weight saving

Thanks guys, Looks like we have cutaway for SU-35,27 and 27SKM

 

Namenlos Ein,

I trying to see first two photos, but my browser just sit there loading, What version SU-27 are they from?

What version MIG-29 is that, does it say SD in the top?

Is weird, when I go to the websites, I have no problems, but when I click on the photos, I can't download them. Maybe be is my internet protection or something, o well thank you for the links

For you guys that have never been around a Jet engine, some nice details

So I just picked up a copy of Combat Aircraft (Vol 11 no 10 October 2010) Is a old one, but is hard for me to find this and I love it, so I had to get it... Anyway;

I was reading an article about the SU-35 and I realize that the aircraft designation is very complicated. For example, and I quote;

...The original SU-27M (known internally as the T-10M or T-10S-70)...

And that is the old version of the SU-35 which got re-modified as the SU-37 ( Bort 711)

Then you got the other versions like SU-30 MKI (India) MKK (China) MKV (Venezuela) MK2V (Vietnam) MKA (Algeria) which are easy but then you reed about SU-30M3 that uses a MKK frame with SU-27M fins and canards. Then there is the aircraft factories, KnAAPO and IAPO that produce some of this SU-30 versions versions.

 

Anyway, how do they determine the designation? I always thought it was based on the aircraft mission, is this accurate?

 

How does the company or factory thing work? Do they work with Sukhoi or does Sukhoi just contracts them to build the aircraft?

It used to be - that is to begin with they kept the Su-27 designation and then just added a suffix to differentiate them....examples:

 

- Su-27P single seat interceptor (for airdefence forces - no A2G capability)

- Su-27S single seater with A2G capability (for regular airforce)

- Su-27UB twin seat combat trainer

- Su-27PU twin seat interceptor/trainer - later "Su-30"

- Su-27K single seat deck fighter - later "Su-33"

- Su-27M single seat multirole fighter - later "Su-35"

- Su-27IB twin seat strike aircraft - later "Su-34"

 

...etc.

 

But then they changed the designations as indicated above and things started to get silly :D - e.g. they made a multirole version of the Su-27PU/Su-30 and named it Su-30M, then offered it for export adding a "K" for "commercial"(or something). Since the configuration of Su-30MK aircraft depends on the requirements of the customer country, it was necessary to add yet another suffix to indicate this.

 

How does the company or factory thing work? Do they work with Sukhoi or does Sukhoi just contracts them to build the aircraft?

 

That would be the latter - Sukhoi is the design house, while Knaapo and Iapo are production facilities. In Soviet times Knaapo built the single seaters and Iapo the twin seaters, but now Knaapo is also building two-seaters(e.g. the Su-30MKK for china was built at Knaapo) - I guess the reason could be that Knaapo is the largest facility and that while the number of single seaters far outnumbered the twin-seaters in Soviet times, it seems to be the reversed for present day export orders.

Cool Thanks.

 

I don't know why I never tried this before. I just went to the KNAAPO site. Lots of photos and info.

What is the name of other factories?

I know that Sukhoi has KNAAPO and IAPO, what bout MiG, Tupolev or Antonov? What is the name of their factories?

 

Also, check this out;

I wonder what happen to the right main landing gear strut?

:huh:

 

I see nothing wrong with it!

 

MiG aircraft of today are being produced in MAPO (Moscow Aircraft Production Organisation). Beside MiG jets you'll see Kamov helos produced there as well! It was founded in 1996.

 

However, most of the "cold war era" MiGs were produced in SOKOL plant (Nizhniy Novgorod), read more about it here:

:huh:

Weird, to me it looks like the right wing is lower. Maybe indicating fuel unbalance or main gear strut collapse.

 

At any rate thanks

[Vekkinho]

Well the photo seems a bit angled plus there's a light coming from the port side so this part of aircraft is more visible. Movable LERX are lowered only in front of the port engine so this might trick you into thinking it's asymmetrical.
