Как же заменить двигатель на JAS39
The Gripen engine change procedure famously beat the hour during the Indian Air Force trials for the MMRCA. A recent requirement in Sicily for an engine change for a Swedish Air Force JAS 39 demonstrated how the aircraft manages to clock in a changeover time of a couple of hours even in the most complex of situations and the ribbing among engineers that happens when it takes a little more. For an aircraft that commits itself to availability, the Sicily episode was yet another confirmation of the commitment.
Here are some excerpts from the action on the ground from the Swedish Air Force from a write up by Johan Brolin (Google translate has been used for translating the story)."Thursday, July 14 technicians said that an engine change on one of the JAS planes in Sicily had to be implemented. On Friday night at 20:15, the new engine arrived in a C-130 Hercules. Activity began immediately after the engine arrived in order to have the plane with the replacement engine in operation at the earliest. It's incredibly impressive to see, and one can almost feel the energy that exists among the staff around the plane during the engine change.
When the job was finished at midnight and it was found that the work took about three hours, ie little longer than normal, the staff jokingly agreed that it was partly due to the boss who had taken part!
After an engine change, a trial run of the engine is done to check that everything is as it should. Back in Sweden, the testing is done in special places that are prepared for just this purpose. These include devices for anchoring of the plane that allows it to be tested at full power. In Sicily it is a bit different. We must go to a special plate where there is a huge heavy wire fastened to the ground as we switch on our equipment on. From the time the engine was ordered until it was replaced and tested, it took about 36 hours. Good job."

Rafale в Бразилии. FX-2
Текст (перевод с португальского):
This is what Jean-Marc Merialdo, Rafale representative in Brazil, said to the IG journalist during an interview about the FX-2 contest.
According to Merialdo, the primary asset of the Rafale is the unrestricted transfer of technology garanted by the French presidency :
[...]"Our package of technology transfer is priceless. It is total, complete, all the technology of the fighter"
" full and complete package of technological and industrial cooperation , including know-how, software, hardware, processes and delivers all the tools and source code needed without any restriction."
[...]
"The ToT is guaranteed by the French government and is based on a range of partnerships with Brazilian industry and universities, and falls into a strategic partnership signed between President Lula and Sarkozy at the end of 2008."
When asked about the technical benefits of Rafale over its 2 competitors, Merialdo said that the French fighter is more modern than the F/A-18E and more powerfull (range, payload) than the Gripen. He also emphasized on the data fusion which allows the plane to gather data from internal and external sensors and to conduct several missions during the same flight as demonstrated in Libya.
Concerning the usual claim that the Rafale is the most expensive of the 3 fighters Merialdo was rather elusive :
[...] "In a competition you do not disclose your price if you don't want to give some advantage to your competitors. About the cost of operation, I can not give you the figure for now, because they are being further refined, especially with the operation in Libya. I can say that they are constantly decreasing."

Новости о тендере MMRCA
NEW DELHI (PTI): India’s Air Chief Marshal P V Naik has said the likely winner of the multi-billion dollar combat aircraft deal would be known in the "next five to six" weeks.
"The next step is to call vendors and open up the commercial bids. I think in the next five to six weeks, I expect that the L1 (lowest bidder) would be decided," he said on Tuesday.
As per the Defence Procurement Procedure (DPP), the lowest bidder in the multi vendor tenders is considered to be the winner of the deals.
European consortium Eurofighter Typhoon and the French Dassault Rafale are the two companies in race for supplying 126 Medium-Multirole Combat Aircraft (M-MRCA) to the Indian Air Force.
The two companies were shortlisted after a five-year long competition between six companies including the American Boeing and Lockheed Martin, Russian MiG 35 and Swedish Saab Gripen.
The IAF chief said that major procedures such as the completion of the Technical Offsets Evaluation Committee report have been finalised.
Commenting on the Mirage 2000 aircraft upgrade programme, Naik said the deal worth over Rs 10,900 crore would be signed soon under which 51 aircraft would be upgraded.
The Cabinet Committee on Security (CCS) had recently cleared the proposal for upgrading 51 aircraft to the Mirage 2000-5 standards in collaboration with France.
On the results for procuring heavy-lift and attack helicopters, the IAF chief said the trials have been completed by the force and the trial report would be submitted to the Defence Ministry soon.
On the controversy surrounding the procurement of the basic trainer aircraft, the IAF chief said, "I am not aware of any Korean controversy. They have written a letter that they should be given a chance. Correct procedure has been followed and Swiss firm Pilatus has been declared as lowest bidder.
"There is no controversy as far as I am concerned. Now the commercial negotiations will start."
On the highest point in his career, Naik, who is retiring on July 31, said it came when he visited the US for the Red Flag exercises as the Vice Chief of Air Force where the IAF came in for lot of praise for its efficiency and professionalism.
"The conquering of the Mount Everest by three women officers was the highest point as Chief of Air Staff," he said.
Asked why the IAF was not taking part in multilateral Red Flag exercises held in the US, he said, "Taking part in such exercises costs money and that is why we have decided that we will take part only once in five years in such exercises. So, the next exercise may take place in 2013."
On queries about the possibility of Indian armed forces to carry out Abottabad like operations, he said, "Yes, we do have the capability to carry out a similar operation."
To a query on the proposed Medium Combat Aircraft (MCA) being developed by the DRDO, the IAF chief said, "At present, I have been so busy with the LCA that I have had no time to think about MCA."
"Its development has already started on drawing board. Once developed, it will be a twin engine aircraft. I think it will be an improvement on the LCA," he said.
