^^Wiki aunty says that the Sea Wasp retains the same length and max diameter.
Re: Indian Military Aviation- Jan 10 2012
that is indeed strange. my memory keeps telling me MK can't be retrofitted on older fulcrums due to a size problem but can't find the relevant articles.
the klimov site carefully avoids mentioning the dimensions of the MK and mentions only the mig-29K and mig-35. http://en.klimov.ru/production/aircraft/RD-33MK/
if it could be done, won't the russians have offered it as part of the upg package ?

Re: Indian Military Aviation- Jan 10 2012
Well the MK uses new materials (SCB possibly) to improve thrust. It has FADEC as well. So the price difference could be substantial. Maybe the IAF though the extra money wasn't worth it.Rahul M wrote: if it could be done, won't the russians have offered it as part of the upg package ?

you are probably right -I do not know how much of a problem it is or not. And of course if i do come to know - probably not something that can be told here.
I can only assume the IAF is well aware of it and has taken appropriate steps to minimise the disadvantage

Re: Indian Military Aviation- Jan 10 2012
boss I understand that. but that's hardly their (russian's) headache. while they keep offering every probable and improbable kit, RD-33mk was not offered on the IAF mig-29. neither have they offered any general upg package with that engine to the international market AFAIK. that is very unlike how the russians approach the upg business.
moreover I keep having this distinct memory of having read something about the mismatch b/w rd-33mk and older migs. will keep looking.

Just saw this pic by Ajai Shukla ji's blog. I just love the An-32s. Just goes to show why it is IAF's work horse. They are filling in the belly of the beast even as the engines keep humming ... speaks volumes about the uptime and the turn-around time of the beast in India. Just love it!

Re: Indian Military Aviation- Jan 10 2012
About smoky RD-33s, some quick questions:
1) In what regimes do these birds smoke? I notice it at slower speeds when sudden acceleration is required, esp. when coming out of a turn. Dunno (doubt) if it will happen during cruise. Might not be such a great issue once maneuvering starts in close range - they've done well in most DACT exercises and they've fought against M2ks, F-16s, the entire lot of them - the IAF still considers this bird a premier air superiority fighter. My point is that this weakness it seems is a problem at a particular flight regime and does not degrade performance decisively, especially with the availability of the latest OLS, which can probly allow pilots to "see" much further than eyeball mk1. Further, I have always noticed this at lower altitudes (take off-landing or airshows), what about higher altitudes? Here is an interesting dog fight between the fulcrum and falcon (SwAF), the fulcrum does smoke but not all the time.

2) Do we know that the RD-33s in the original video were upgraded/new engines?
Here is another video of VVS MiG-29SMTs with the RD 33.3 engine, it does smoke BUT nothing overthetop like we saw in the earlier vid.http://www.patricksaviation.com/videos/Radetzky/5192/
3) RD 33MKs are not iirc possible on the SMT - Rahul has a point, they have never been offered or advertised as such, although the TVC is available.

Re: Indian Military Aviation- Jan 10 2012
Yeah i have applied for it
Re: Indian Military Aviation- Jan 10 2012
So the source of smoke is just like good old smoke --> incomplete combustion? If I am not wrong incomplete combustion means reduced thrust from engine in those altitude regimes where engines get smoky?
Re: Indian Military Aviation- Jan 10 2012
at high alt, would the unburnt fuel residue result in formation of contrails in certain weather conditions like moist air?
Re: Indian Military Aviation- Jan 10 2012
Don't worry about reduced power ... the amount of fuel these engines burn, this amount of smoke is nothing ... The smoke is a concern for other things ... ease of tracking the plane and its maneuvers.
I think CM sahab you are right, the smoke seems to increase at higher AOA. This could be easily explained on the basis of airflow into the intakes being most constricted at these regimes

Re: Indian Military Aviation- Jan 10 2012
Don't need unburnt fuel residue for that. Contrails are formed by condensation of water vapor as the engine exhaust cools down. All that is needed are hot exhaust gases and moisture in the air. Sometimes the contrails are formed even at the center of wingtip vortices.Singha wrote:at high alt, would the unburnt fuel residue result in formation of contrails in certain weather conditions like moist air?
Re: Indian Military Aviation- Jan 10 2012
Got a Q:
In his comment here, Prasun says "By the way, your desperate prayers in another blog for the ‘kabutar/panchi’ to take flight (for the NP-1) may also be required for the HJT-35 ‘Sitara’ IJT, since A K Antony yesterday in Parliament virtually confirmed that the IJT is for all intents and purposes now a dead duck. What a gigantic waste of R & D effort!!!"
Is this true? I havent seen it anywhere else. Why would they kill the IJT project?

Well, I think Gupta might be well off the mark on this one too - in the Takeoff issue linked by Koti (many thanks), there is a nice spread on the IJT, which states that a LRIP batch of 12 is on order and 73 more have been approved, pg. 13.merlin wrote:While that may be so, updates on the IJT are far and few between.

Re: Indian Military Aviation- Jan 10 2012
A330 vs IL76 is a somewhat strange contest. the 330 is much bigger and hence will fly longer and offload more fuel. whether we need that or not is debatable, but I guess with stuff like Phalcons, CABS AEW, future GMTI planes, P8s, MKI fighter screens increasing a single plane able to feed more birds does add some value.
Re: Indian Military Aviation- Jan 10 2012
Get 12-14 used 330's for 100 million dollars each; refurb them. They have a long life and are used to landing and taking off 5 days a week. IAF would never be able to use it to its fullest life anyways. This will serve well for the next 20-25 years and will be a cheaper option.

Re: Indian Military Aviation- Jan 10 2012
Cybaruji,
While your suggestion might be good for getting transport planes, to convert them into tankers we would have to go back to Airbus, especially the boom..
Another option that could be looked into is getting refurbed B767 and approaching Israel to convert them to a Tanker-Transport..

Re: Indian Military Aviation- Jan 10 2012
On paper, yes..
Re: Indian Military Aviation- Jan 10 2012
Didn't see this posted here before..
NAL outlines weight savings made to Saras prototype
NAL outlines weight savings made to Saras prototype
India’s National Aerospace Laboratories (NAL) is introducing more composite materials into its 14-seat Saras push-turboprop aircraft.
The first two prototype aircraft only had composite materials for the control surfaces, such as the rudder, elevator, and vertical and horizontal stabilizer. But the new prototype, the PT1N, now being built, has a composite wing and bulkhead as well as composite materials for the front top skin and floor sections, a NAL official tells AviationWeek on the sidelines of the India Aviation airshow in Hyderabad.
About 33% of the aircraft will be made of composites. The use of composites - and optimization of the aluminum alloy fuselage - will deliver a 500 kg weight saving over the earlier prototype, the NAL official says.
Saras is a 14-seat transport aircraft that is powered by two turboprop engines, each fuselage-mounted towards the rear, and well back from the wings.
The official says the new prototype has Pratt & Whitney PT-6 engines generating 1,200hp whereas the PT-6 engines on the earlier prototype only generated 850 hp. NAL decided to increase the engine’s thrust to ensure the aircraft can achieve a single-engine take off and landing. This is an EASA and FAA requirement, so the aircraft can land and take off even if one of the two engines shuts down, he says.
HAL actually lost one of its first two prototype aircraft in 2009. It crashed after one of the two engines suddenly shut down. All three on board died in the crash.
The organization’s joint head of knowledge and technology C. Divakar says it aims to first achieve military certification by the end of 2013, after which it will examine trying to gain civil certification for the Saras.
Divakar says the Indian air force has agreed to buy 15 Saras aircraft and that state-owned Hindustan Aeronautics will be the manufacturer.

Re: Indian Military Aviation- Jan 10 2012
IAI has exp of converting B707 and B767 into tankers. there must be plenty of 767 lightly used and lying in boneyards. in any case even ex-airline ones are good for cargo fleets which => good enough for tanker use. Boeing likely provides OEM support to a bunch of conversion cos like IAI.
imo its a far cheaper option to convert used planes to tankers than buy new A330...prolly half the cost.

33 % composite by weight is quite good even by todays modern standards , 500 Kg weight savings will compensate weight issue that it has faced in its early development.Kartik wrote:About 33% of the aircraft will be made of composites.

They should work in parallel with the low cost carrier and begin pitching Saras as means for short distance regional transport which needs minimum airport infrastructure to operate .....commercial sale would add value to the aircraft and boost confidence of HAL and End Customer.

These are 2 key differences between the 2 tenders. I think IL-78MLI has an edge given the lower upfront cost which is the deciding factor.

Probably, the confusion is due to mixing of Series 3 and Sea Wasp info.
No. You can find AF officials calling the RD-33 engine as such. Series 3 engine is the same as Series 1&2 engine with new materials involving no design changes. Becoz of new materials, it offers higher TTL and TBO, otherwise the engine design is old. This engine is not considered for future applications like MiG-35. So this gives an indirect message that the design is not modern.

If it comes to converting civilian planes to tankers then we have a boatload of planes we can get from Kingfisher airlines
Re: Indian Military Aviation- Jan 10 2012
they could be better used to haul palletized military cargo and personnel if onlee the IAF would adopt that practice. not everything needs the rough field and STOL abilities of dedicated mil transports like C130/AN32/IL76/C17. they will do fine flying into the major concreted airports which they do everyday incl jodhpur, bagdogra, leh, tezpur, port blair, dabolim, pune for instance all shared with civilian ops.
Re: Indian Military Aviation- Jan 10 2012
Planes belong to the creditors and not to the people of India. KFA has tax liabilities to Indian govt, but on top of that it has $1.3 billion of debt. Moreover it has massive future payments towards new aircrafts.Yogi_G wrote:If it comes to converting civilian planes to tankers then we have a boatload of planes we can get from Kingfisher airlines
Anyone wanting to get hold of those aircraft will have to pay off the govt, the creditors, the fuel companies, the aircraft manufacturers and then have to pay large sums to convert the aircraft to a cargo configuration. Awful waste of capital!
