There is a documentary on future dogfights on the History Channel. They included Su-30MKI in the fight. One thing they have shown is that the F-22 is totally stealthy. None of the fourth generation fighter aircrafts like the Su-30MKI and Rafale stand a chance since they are not able to detect the F-22. Four F-22s are able to defeat like 25 fourth generation planes.

Is that really true? Or is it just chest thumping? What are India's plan in this area?

Well, nobody else has F-22 except the US, so there's no real need to directly counter it. But India is going in with Russia for development of a 5th-generation fighter.

The Russians are already a raw materials superpower, and they really out to leverage that by becoming a materials technology superpower. They have the deep lab research capabilities for this.

Here's an example of what I'm talking about:

Russia and even India should do further research into this. Space-based materials manufacturing could be a good way to reap more commercial profits from space.

Venezuela's Chavez to buy Chinese K-8 planes Sun May 11, 5:52 PM ET


CARACAS (Reuters) - Venezuelan President Hugo Chavez said on Sunday the OPEC nation will buy Chinese military training planes, expanding recent arms purchases and further cementing a growing relationship with China.


Chavez in recent years has stepped up purchases of weapons and planes. Washington accuses the self-styled revolutionary of carrying out an arms spending spree that could destabilize the region.

Venezuela and China on Friday signed an accord to build a refinery on Chinese soil as part of a broader plan to reduce Venezuela's reliance on U.S. energy markets.

"We're going to buy Chinese K-8 planes," Chavez said during his weekly Sunday broadcast, calling them "excellent planes for the boys."

"We continue working on the issue of military equipment, even though they accuse me of launching an arms race," he said. "I'm not launching an arms race. Military expenditures are necessary for the country's defense."

Venezuela has also bought 24 Sukhoi fighter jets and 100,000 Kalashnikov AK-103 assault rifles from Russia.

Top White House officials have questioned the arms purchases given there have been few military conflicts in the region.

P&WC to supply engines for Russia's Mi-38 helicopter
[quote]By Andrew Doyle


Pratt & Whitney Canada (P&WC) has signed a memorandum of understanding with Helicopters of Russia to supply PW127TS engines for the Mi-38 utility helicopter.

Under the terms of the deal – finalised in Moscow earlier today – P&WC will develop and certificate a turboshaft version of the PW127 for the twin-engine Mi-38 in partnership with the Ufa Engine Industrial Association (Umpo) and the Central Institute of Aviation Motors. The powerplants will be assembled under licence by Umpo, while Kazan Helicopters will manufacture the Mi-38.

“We are very pleased to be entering into this innovative arrangement with Pratt & Whitney Canada, which brings together the outstanding track record and dependability of its engines with the growing capabilities of Russia's aerospace sector,â€

Two years after BR, the TOI has discovered the Da Qaidam missile launch
sites in Tibet/Sinkiang....someone pointed them to FAS.

its part of a pattern of making people aware of nature of PRC threat...

5000km A5 will be needed to counter these threats...cant help it...they
started it first....

UPA is probably using these exposes on PRC moves to keep the cpi(m) in
line on other fronts like food price inflation.

it could also be "hawkish" elements in the system who are fed up of the
country's slumber and decided to rattle the bars of the cage and see who
does what. once exposed there is more media pressure as analysts also
weigh in.

It could also be a US play to justify us signing the nuke deal and growing
"closer" to Massa.

Correct.

the 1st and 3rd points are particularly relevant. The Times Group has been playing up the PRC threat as if there is no tomorrow.

Read this:

http://frontierindia.net/geared-turbofa ... pabilities

Here's also a nice article from latest May2008 edition of Mechanical Engineering Magazine:

[url="http://www.memagazine.org/contents/current/features/changing/changing.html"]Changing the Game[/url]

Potentially radical advances in gas turbines came in all shapes and sizes in 2007.


Just read this and drool:

Engine compressors and turbines run most efficiently at higher rpm, while fans operate best at lower speeds. The unique feature of the geared turbofan engine is a fan hub-mounted epicyclic, or planetary, gearing system that drives the fan at lower speeds, permitting higher bypass ratios. By using a three-to-one gearing system, the GTF fan speed is cut by one-third, allowing for much less fan noise and higher bypass ratios—8:1 to 11:1. With such a high bypass ratio, fuel consumption goes down. A gearbox adds weight to the engine, but this is counterbalanced by the need for fewer engine airfoils, since engine components can now run at more efficient speeds that aren't limited by fan aerodynamics or stress limits.

Air-Show: F-22, F-18...

Postby VikramS » 25 May 2008 11:46

I had a chance to watch an F-22 Raptor at an air-show today which also featured the Blue Angels (F/A-18 Hornet).

The Raptor is in a class apart. It can literally fly like a flying saucer you would see in sci-fi movies. Can turn on a dime, come to a virtual stand-still, and make really sharp low radius turns. And when it turns on the after burner it really moves.

The contrast with the F-18 was amazing. Though the Blue-Angels performed a lot of high-G turns, the space they took to complete the turns was significantly more than what the Raptor took. The Raptor seems to have the ability to literally fly like a helicopter (come to a virtual stand-still) and then literally move in any direction it wants to.

The single Raptor was louder than six F-18s when the afterburners were own.

The only issue regarding is that it is a big bird and with its dark-gray/black surface, is visible to the naked eye at quite a distance. The Raptor on show today was circling in the distance for a few minutes before coming in, and I was able to sight it while it was far away (almost 3 minutes flying time). This was in a relatively crowded airspace with 3 major airports within 25 miles; the Raptor stood out very clearly.

Another interesting aspect was that unlike all other planes on show, the Raptor did not come down to very low altitudes. At the end of the Raptor;s performance there was a formation flight with a P-51 of WW-II vintage. Prior to the formation flight, the old war-bird did a pass 20-30 feet above sea-level; the Raptor stayed much higher. I am not sure why, but was it an indication that the USAF is still not confident enough to fly the F-22 in a sea-skimming role? I remember seeing videos of the Tejas-LCA flying in very low to the ground at an Aero-India. The Raptor kept its distance and do not think ever got below a 1000 ft.

From wikipedia

Motto and traditions

The unofficial motto of the Wild Weasel crews is YGBSM: "You Gotta Be Shittin' Me". This appears prominently on the logo patch of some squadrons. As the story goes, this was the response of Jack Donovan, a former B-52 EWO (Electronic Warfare Officer):
“ This was the natural response of an educated man, a veteran EWO on B-52s and the like, upon learning that he was to fly back seat to a self-absorbed fighter pilot while acting as flypaper for enemy SAMs. â€

Russia ready to offer Algeria MiG 35 fighters

BERLIN, May 28 (RIA Novosti) - Russia is prepared to offer Algeria new MiG-35 Fulcrum fighter aircraft to replace the MiG-29 Fulcrum aircraft due to be supplied under a contract terminated earlier this year, the MiG Corp. CEO said Wednesday.

"We are currently in negotiations on delivering our fighter aircraft, including MiG-35s, to Algeria," Anatoly Belov said.

Algeria has requested that Russia deliver between 14 and 16 additional Su-30 Flanker fighters in exchange for the MiG-29s.

Russian arms export monopoly Rosoboronexport signed a $1.3-bln contract to deliver 29 single-seater MiG-29SMT fighters and six two-seater MiG-29UB fighters to Algeria in March 2006 as part of an $8 billion military-technical cooperation agreement.

After receiving 15 MiG fighters, Algeria refused further deliveries in May 2007 and froze all payments with Russia in October 2007. Algeria claimed the MiG-29s were of "inferior quality" and demanded that Moscow take back all the fighters delivered.

The aircraft were eventually returned to Russia in April this year and following additional tests could go in service with the Russian Air Force.

Under a 2006 contract, worth about $2.5 billion, the Irkut corporation is supposed to deliver a total of 28 Su-30MKA fighters to Algeria until 2010. The company has supplied six aircraft so far.

The Irkut Corporation, part of Russia's United Aircraft Corporation (UAC), created in 2006, manufactures variants of the famed Su-30MK for India, Algeria, and Malaysia.

Cluster ban bomb adopted by 111 countries

...
But crucially, the United States, Russia, China, India, Israel and Pakistan - all major producers and stockpilers of cluster bombs - were absent from the Dublin talks, and thus not part of the agreement....


So shows where the future areas of conflict are.

Russia ready to offer Algeria MiG 35 fighters


That is a desperate bid IMHO! Algeria got MiGs and now want SUs. Offering the 35 is not a solution to this problem, as much as MiG would like to be the SU of the future.

I really liked this picture:

Image

Shown in the inset, is the Mars Phoenix Lander descending, with the Heimdall Crater looming large behind it. Even though it looks like the lander is falling into the crater, it is actually miles in front of it. You really get a sense of scale, seeing the tiny lander with the gigantic crater as a backdrop.

U.MIchigan simulations predicted Mars lander would hit subsurface

ANN ARBOR, Mich. -- University of Michigan simulations correctly predicted
that the pulsed jets of the Mars Phoenix lander would strip the soil to the
subsurface ice or rock as the craft touched down.

Photos of the area beneath the craft on Friday revealed a hard surface that
scientists say may be ice. It could also be rock, and researchers won't know
until the Phoenix can dig into the dirt. But it's clear the craft cleared
away soil as it landed.

"This is exactly what was predicted by our group," said Nilton Renno, an
associate professor in the Department of Atmospheric, Oceanic and Space
Sciences. "We've seen the most amazing photos of the hard surface under the
thrusters. The brightness and smoothness suggests it is ice."

This would mark the first time a spacecraft has touched ice on another
planet, Renno said.

Renno and Manish Mehta, a doctoral student in the same department, performed
a series of tests for NASA over the past year in part to determine how the
lander would affect the place it touches down. Phoenix's pulsed jet steering
and braking system is unique.

Mehta performed the most recent simulations in April at NASA Ames Research
Center using properly-sized crushed walnut shells and other fine dust
particles to simulate the Martian soil. Mehta showed that the pulsed jets
could cause a different, more explosive erosion than the continuous jets of
the Viking spacecraft, which landed on Mars in 1976. The Phoenix landing
process involved thrusters firing in bursts to slow the craft and guide it.

"In our simulations, the pulsed jets excavated to the hard, icy surface
within less than a second. The pulses fluidized the bed under the thrusters,
so that the soil behaves like water," Mehta said.

These results were presented at the Phoenix Science Team Meeting at Tucson,
Ariz. on May 19 and a site-alteration report was submitted to JPL and
Lockheed Martin.

Mehta suggested to the Phoenix science team that they check under its deck on Mars to find exposed ice.

From what I can discover, this is a very small company, which has yet to sell anything, & so far, has produced a surprisingly large number of models & slick brochures.

http://tinyurl.com/5a4upa

Since then, it has moved from New York to Maryland, having negotiated local government assistance.

It's good at marketing & fundraising. It remains to be seen if it can build UAVs.
