PAK-FA, T-50: News #2

I personally think that the western hud tends to overload the pilot with lots of informations he does not need - i hope Russians will not follow in American footsteps.

The main goal of the technology in 5th gen fighters is to process information and display it in a simple way to the pilot while hiding non relevant information to prevent information overload

They are working on helmet mounted displays both for fighters and helicopters and I suspect they will keep such things secret for the moment.

I was also thinking that it would be much harder for a SAM to hit it at that height. Also whether key rival AAMs would have reduced or zero capability when the PAK FA is at max height. I know a fair number of missiles cant function that high up.

And even the ones that do have very thin air to work with... this means blast waves of explosions are much less effective so fragmentation is relied on rather more for a kill. The thinner air means after burning up a lot of energy to climb up to those heights the small control surfaces of the missiles will have less bite in the air so will have reduce manouver capability... and also the height gives the pilot more time to react to an attack than if they were lower down.

At 23km up there are no clouds to hide behind and no weather to be a problem either.

[One problem with attacking such planes is that normal missiles cant function at that height.

Missiles fast enough to get up to those heights  should have some method of manouvering at that height.

Also keep in mind that a hypersonic bomber with people in it will not be able to turn much... remember that the g forces of a turn greatly increase with speed... a helicopter travelling at 150km/h might not be able to pull more than 2-3gs, while travelling at 1,500km per hour a sudden 90 degree turn might result in 200gs... if it was possible.

Has there ever been a true fighter aircraft that used a full pressure g-suit?

The Mig-25 and Mig-31 use a pressure suit... but very few real pressure suits are actually full pressure suits... one of the biggest problems with the Apollo-Soyuz docking was that they each operated at different pressures and that the connector had to stabilise each side so they could connect.

Neither operated at full Earth sea level air pressure as the higher the pressure the stronger the pressure vessel needs to be, which adds weight and complicates breathing gasses used.

BTW nice vids guys...

Practice for MAKS 2013?

The Indian version of an Indo-Russian fifth-generation fighter plane is going to be lighter weight, more powerful and less visible to enemy radars that the original Russian version, according to a senior executive at Hindustan Aeronautics Limited.

Under a joint project with Russia to build a fifth-generation fighter aircraft (FGFA) India will modify and customise the prototype Russia has developed independently.

“While the Russian version of the FGFA is all-metal, ours will have wings and empennage (vertical and horizontal stabilisers) made of composite materials,” said S. Subrahmanyan, Managing Director of MiG Complex at HAL.

“The use of composites will reduce the plane’s weight and give it lower signature. Our version will also have more advanced Indian-made avionics,” Mr. Subrahmanyan told The Hindu at the Moscow Air Show-2013. He is leading a HAL delegation to the biannual air show being held this year from August 27 to September 1.

“Thanks to these improvements we will get a better and more powerful platform,” Mr. Subrahmanyan said.

The FGFA is going to be India’s biggest and most ambitious defence project and the largest joint venture with Russia. Earlier this year the two sides completed the preliminary design of the FGFA and are now negotiating a detailed design contract. Mr. Subrahmanyan said he hopes the contract could be signed before the end of the current year.

Four Russian prototypes of the fifth-generation fighter, codenamed T-50 or PAK-FA, have performed more than 200 test flights since January 2010. The Russian Air Force plans to begin inducting the plane in 2015.

HAL is to get three Russian prototypes for re-design and testing in 2015, 2016 and 2017, and will hand over the first series produced aircraft to the IAF in 2019, Mr. Subrahmanyan said.

The FGFA project will take the Indian expertise in aviation technologies to a much higher level.

“We’ve moved from license production and technology transfer to co-design and co-development,” Mr. Subrahmanyan said. He pointed out that India supplies avionics for Su-30 Russia is building for Malaysia and Indonesia.

“Co-design offers far greater scope for knowledge sharing compared with license production. In co-design projects all Intellectual Property Rights (IPR) are jointly held by parties involved,” Mr. Subrahmanyan added.

India is currently working on two co-design defence projects with Russia – the FGFA and the Multi-role Transport Aircraft, which is already in detailed design stage.

With the West, India has so far had only one co-design project – the Advanced Light Helicopter Dhruv, developed with assistance from Germany’s MBB.

These Indians with their low aptitude take tremendous pleasure in making a fool of themselves . As they say in the UK that these Indians are the best specimen of God's perfect Asshole.

You sure its not lighting + 051 being flogged around more?

Guarantee there won't be such differences.

Russian version all metal? LOL! Thats just incorrect.

More advanced Indian electronics? Please....

I recall that in the past the Soviets made sure that there combat aircraft had a similar or identical cockpit layout, i was wondering if this practice is still continuing in Russia today?

Of course little tidbits of what may as well be complete BS, like the 20 year old APG-77 is "more advanced" than the NIIP AESA, caught my eye.
