Thoughts regarding "Admiral Kuznetsov" deployment to Syria...

[artik]

A thing thats pretty stressful to engines and airframes even under normal conditions without having to stress them further with maximum loads. Its not like the Russians need more hard flying on their engines in the first place. Isnt that one of the main reasons for the ski jump?

Actually ski jump is way more gentle on the airframe during the takeoff than catapult. Catapult uses single point to accelerate an aircraft on full load during very short distance of +-100m. Giving up to 4g acceleration.

It is one of the heaviest duty on the airframe especially for tankers. It is actually more stressful than landing.

The ski jump is much more gentle. In fact virtually all land based fighters even with fragile gear like f16 are capable of ski jump. USAF actually tested it as an approach to handle takeoff from damaged airbase.

If you take a look on the simulation I posted before you'll see that the acceleration is quite low.

Rich, it's no more stressful for the engines than a normal take off on a normal runway. I don't understand how you would think otherwise?

I looked once again on the data and mig 29k has +-0.73 thrust to weight ratio at Max takeoff weight su 33 has 0.78 in comparison to 0.67 of super hornet.

Indeed according to my simulation with such a T/W ratio it is not problem at all to takeoff from long 180m strip at full takeoff weight having only 25 knots of WOD

25 knots of WOD

Can the Kuz achieve that on a no-wind day?

[artik]

Yes, it can go 29.


Also I noticed that I missed few more parameters

Kuznetsov's takeoff strip is 195 and not 180m

So using SH data for lift/drag ratio I get for mig

21 knots of WOD for positive climb ratio requirement
9 knots of WOD for zero altitude loss requirement

See http://cppcms.com/files/skijump/#results


In reality it should be even lower as lift/drag calculated using single engine failure on takeoff that adds more drag due to assimetry of thrust


Still in hot and humid conditions it would likely need more WOD

[Serenity]

Yes, it can go 29.

On paper? Or in practice?

Things are going well, A MiG-29 crashed yesterday while attempting to land on the ship...

Interesting what was the reason of the crash...

To be honest it seems like they pushed barely trained pilots to the service. I've read recently that only few month ago MiG-29 pilots were doing training at Nitka ground test facility at Crimea before the got to actual flying. I have strong suspicions, that it was some issues with training or pilots were pushed to harsh conditions too early. I'm not sure that few month from initial training on land based facilities to combat deployment enough ;-)

Finally India flies these migs for much longer period from Vikramaditya and even longer from shores -  also Indian Navy have way more experience with carrier operations than Russia - they do it since 1961...

USNI Navy website has reported that the 6 SU33s that were embarked on Kuznetsov are now being used as land based attack aircraft, and no longer on the carrier.  That leaves 3 Mig29ks single seaters, as the 2 seater is the one that crashed.

As I said in another board, "Admiral Kuznetsov" is is more of an inter-coastal ferry than an aircraft carrier.

It's the best carrier in the world

The UK has a new carrier but no planes to put onit
