    R.I.P.

    http://blogs.wsj.com/indiarealtime/2014/05/27/indian-fighter-jet-crashes-in-jammu-and-kashmir-killing-pilot/

    A Soviet-era fighter jet of the Indian Air Force crashed Tuesday morning, killing its pilot and raising fresh questions about the MiG-21 aircraft that has been involved with many fatal accidents in India.

    On Tuesday morning one of India’s MiG-21 Bisons took off for a training sortie from an air force base in Srinagar in the state of Jammu and Kashmir then crashed about 10 kilometers short of another air force base in the northern state, an air force official said.

    “A court of inquiry has been ordered to determine the cause of the crash,” the official said.

    The accident happened just as India’s new defense minister, Arun Jaitley, assumed office. Mr. Jaitley—who has also been appointed as the country’s minister of finance and corporate affairs minister—said he would only hold the position for a short time until a new defense minister is appointed.

    In December the air force began phasing out the MiG-21 which has been its combat backbone for decades. The aircraft has been nicknamed the flying coffin because it has been connected to so many crashes. In 2012, India announced that more than 200 people including 171 pilots have lost their lives in accidents with the MiG series of aircraft since 1971.

    The air force had been hoping that the body count would go down with the addition in recent years of new aircraft–including Russia’s Sukhoi Su-30 fighter jets and Boeing Co.’s P-8I long-range maritime patrol and anti-submarine warfare jets.

    India has yet to decide on whether it will go through with its decision to purchase 126 Rafale fighter jets from Dassault Aviation S.A. of France as one of the aircraft to replace the MiG-21. India had around 250 MiG-21 planes as of last December.

    India’s other armed forces have also been hit by accidents in the last year.

    In March, a Lockheed Martin Corp. C-130J Super Hercules transport plane crashed in central India, killing all five air force personnel on board. The same month, an engineer was killed in an accident at a construction site building a submarine for the navy.

    On Feb. 26, the country’s naval chief, Admiral D.K. Joshi, resigned to take responsibility for recent accidents, including a fire on a submarine earlier that day that left two crew members dead.

    The most damaging accident happened last August when 18 sailors died after explosions and a fire swept through a submarine in a Mumbai dockyard.

    How long before major western nations, start buying Asian manufactured combat aircraft ?

    The major European airforces will keep using their own Eurocanards until 2040s or even 2050s.

    After that, what shall be the next step for these European airforces (cooperative development, buy American, buy Russian, buy Asian, or just say good-bye to airforce……..) ? Right now only God knows:D

    1. The KF-X has already gotten its first foreign customer: Indonesia.

    2. On 5 January 2014, DAPA announced the approval of development of the KF-X.

    3. If everything goes well, the KF-X shall be able to enter introduction at the time of 2023.

    A big step in India’s Rafale jet deal with France

    New Delhi: The Indian government and French aerospace major Dassault have sealed a work share agreement in what is being described as a big step forward, almost two years after negotiations began in the deal for 126 Rafale fighter jets to be bought by India.

    The government’s Hindustan Aeronautics Limited or HAL will do 70 per cent of the work on the 108 planes that will be manufactured in India. Dassault would do the rest of the work, sources said.

    The first 18 of the fighters will be fully manufactured in France and will be brought to India in “fly-away” condition.

    India has apparently rejected Dassault’s reservations about having HAL as the major player.

    The final contract, though, is still far from being signed. For one, India’s Ministry of Defence has no money in the current financial year that ends this month, for initial payment.

    Also, general elections are due by May and the final contract will only be signed by the next government, if it chooses to go ahead on the same terms and conditions.

    A few things regarding the F-22’s acceleration. According to the 2010 SAR, the unclassified acceleration of the F-22 is 52.4 seconds from Mach 0.8 to 1.5 at 30,000 ft, apparently at full fuel.

    Very astonishing performance if it is true ~ Especially when you consider that it may take EF-2000 no less than 70 secs to achieve such kind of acceleration……

    http://eurofighter.airpower.at/technik-daten.htm

    Beschleunigung von Mach 0,9 (~951 km/h) auf Mach 1,2 (~1.267 km/h) in Tropopause: 40 Sek.

    Beschleunigung von Mach 0,9 (~951 km/h) auf Mach 1,4 (~1.479 km/h) in Tropopause: 62 Sek.

    According to the information and data mentioned above and from some other previous reports, my personal initial estimation to the RBE-2 AESA radar:

    1. Radar weight: 290 kg (20 kg heavier than the RBE-2 PESA radar).

    2. AESA with around 1,000 GaAs units and 10 years of service life with no need of major overhaul.

    3. Reducing the mean time between failure on the RBE2 AESA by a factor of 10 compared to the RBE2 PESA, according to Thales.

    4. Average output: 10 kw.

    5. Maximal effective A2A detection range: around 112.5 nm / 208 km.

    6. Effective tracking range for RCS = 3 m2 enemy fighter: around 90 nm / 167 km.

    7. Ability to scan up to 70° on either side of the aircraft axis.

    8. Three to four times of search volume comparing with RBE-2 PESA.

    9. Ability to track and prioritize up to 100+ targets simultaneously.

    10. SAR mode with sub-metric resolution.

    Serious Squall

    Jean-Michel Guhl

    The RBE2 (PESA) gives a tracking range beyond 60 nautical miles against a 30-square-foot target, with detection ranges up to 75 nautical miles. The radar can track and prioritize up to 40 targets simultaneously and engage up to eight with Mica, and soon Meteor, air-to-air missiles.

    According to some information that I read a few years ago, the RBE-2 PESA radar:
    * Weight: 270 kg.
    * Being able to track 40 targets at the same time in A2A mode.

    Therefore, according to the article mentioned above, the RBE-2 AESA radar:

    1. 290 kg in weight, which is roughly equal to the weight of APG-79.

    2. Might be able to track no less than 100 targets at the same time in A2A mode.

    So, if an F-15C were to be fitted with -229 engines, it would outaccelerate the Su-35S? That seems a bit silly, since the clean Su-35S is already a monster at acceleration and will outaccelerate an F-22.

    http://forum.keypublishing.com/attachment.php?attachmentid=221413&d=1380590216

    The estimation for Su-35 acceleration mentioned above seems ridiculous.

    The real data: it takes the clean Su-35 about 22 seconds to accelerate from 0.5 to 1.05 Mach at the height of 1,000 m.

    How could it be possible for the same clean Su-35 to accelerate from 0.8 to 1.2 Mach with less than 24 seconds at the height of more than 9,000 m ?

    F-15E with -229s, clean no CFT:

    [ATTACH=CONFIG]224549[/ATTACH]

    According to 600-1100 (approx. M0,5 to M0,9) and 1100-1300 (approx. M0,9 to M1,05) times, they are pretty much equal in acceleration. Though F-15C with -220s MAY accelerate slightly better than F-15E with -229. Too lazy to look into that.

    They are pretty much equal in acceleration, when:

    1. The clean F-15E accelerates at the height of 10,000 fts (3,048 m).

    2. The clean Su-35 accelerates at the height of 1,000 m.
    http://www.knaapo.ru/eng/products/su-35/index.wbp

    And the acceleration will slow down when the height for acceleration increases.

    Therefore, I think the acceleration performance for a clean Su-35 at the height of 1,000 m shall be no better than the acceleration performance for a clean F-15E at the same altitude.

    I don’t believe the Typhoon now is as developed as any customers want it to be. It does not provide the strike capability of the Tornado. What are the facts? Have Meteor, Brimstone, Storm Shadow integration contracts been signed?

    The integration contract for Meteor BVRAAM has already been signed this year. As for Brimstone and Storm Shadow, well, let’s us hope there will be good news (confirmatory contract of integration) in 2014, 2015, or 2016……..:apologetic:
