    sorry phil missunderstanding and comunication deficiency on my part.

    I ment the design requirements of the engine it self. I mean if it does not achive the mass flow rate required, or that it does not operate efficiently at the altitude the engine was supposed to be most efficient etc etc.

    p.s. i honestly dont know much about the tornados ..i guess i should read up on the different varients.

    I dont think the nuke facilities should be attacked (too much to risk and cant garantee that civilians will not be effected)

    but if it did have to happen then the Israeli subs with cruise missiles would be the most obvious choice.

    I think you are right there is bugger all mysterious about it then, I suppose it is difficult to build a truly bad engine then and I also suppose development is restricted to shapes and materials used for higher temperatures? The same as with a car engine I assume that the colder the air going in, the more power coming out because of the temperature difference in the system?

    Yup basically..

    Thermodynamics are the key here.. I dig up a engine cycle analysis page for u.. and u can play about a bit.

    and yes the materials are the key problems.. ceramics are being used but they are also pretty brittle and cant be used for everything more then the fan the problem is with the turbine part of the engines where HEAT also comes into it.

    as for building a bad engine. well like i say with AC if it doesnt meet ur design requirements then its sh$te otherwise its good. so its all relative as to how good or bad it is i guess.

    if u dont i will!

    why do you guys reply to flames with flames? joking about and sarcasm is one thing but can u guys stop getting RACIAL! its just annoying and disrespectful to all sides and it shows up your own lack of intelligence (i learnt that the hard way)

    P.s. The Indian Muslim populus is the second biggest Muslim populus in the world after Indonesia.

    Although it is true that Turbo fans are efficeint they do pose major problems in military use. One being the Size of the nacels (?) required to use the same type of by pass ratios as used on comercial airliners. This would make the aircraft a lot bigger and also heavier. and also a nice hoover to clean the runways with.

    Turbojets are prefered more for the praticality of it.

    And yes the EJ engines is one of the most advanced engines out their.

    China has no influence on anyone in the EU at the moment i guess..not untill the EU starts to enter Chinas markets properly.

    NPT has no reall meaning..

    Its used as a control to allow countries to control arms transfer to their prospective fo’s its more of a valve.

    Egypt’s spy drones spook Israel
    Uzi Mahnaimi, Tel Aviv

    ISRAEL has threatened to shoot down Egyptian drones spying on a nuclear installation and a ballistic missile site amid growing distrust between the two countries over a military build-up.
    Ahmad Maher El Sayed, the Egyptian foreign minister, is expected to be taken to task during a visit to Israel this week, his first for two years. Israeli sources claim that the flights contravene a peace treaty between the former enemies that was signed in Washington in 1979.

    “We’ll raise the urgent issue of their spy flights for sure,” said one Israeli source. “However, we know that they may stop them only when we intercept the intruders, and that will not take long.”

    Egypt’s unmanned aerial vehicles (UAV) have been seen in recent weeks over Israel’s nuclear research facilities at Nahal Sorek and the test site for the country’s advanced ballistic missiles in Palmahim, south of Tel Aviv.

    To the alarm of Egypt and other Arab countries, Israel is believed to be one of the few countries in the world capable of launching a nuclear attack by air, using F-16 planes; by land, using Jericho ballistic missiles; and by sea, using new submarines equipped with cruise missiles.

    General Moshe Ya’alom, the chief of staff, boasted last week that Israel could strike within a metre of its targets.

    The Egyptian flights, in turn, are causing concern in Israel. “We’re worried about them,” said an Israeli military source. “That they have the nerve to send their UAVs over is a worrying sign.”

    The new concern reflects broader worries in Israel about the growing military might of Egypt, which, although substantially weaker than its neighbour, has 500,000 soldiers and a strong navy and air force.

    Israel recently asked America not to supply Egypt with advanced F-15 jets or “smart” JDAM (joint direct attack munition) bombs. When the Americans queried the request, they were shown intelligence that revealed the “enemy” in all Egypt’s recent war games was Israel. Cairo’s request has now been put on hold.

    Although Egypt is believed to possess chemical and biological weapons, its overall military might cannot be compared to that of Israel, which has a similar non-conventional capability and nuclear weapons. While the Egyptians are flying their drones over their neighbour, Israel has the Ofek-5 spy satellite, which observes every inch of Egyptian territory.

    Concerns are compounded by the uncertainty of the political situation caused by the poor health of Egypt’s president, Hosni Mubarak, 75, who was forced to interrupt a speech last month when he became ill. Mubarak, who came to power in 1981 after the assassination of Anwar Sadat, has refused to appoint a deputy.

    “Mubarak is committed to peace with Israel,” said one Israeli politician last week, “but it is not certain that his successor will be equally committed.”

    I think you will find it he means Anti Sea Skimming missile capability.

    I dont think i can, but ill try to look. I have not made it up promise, its just that it was from the Sunday Times a hard copy news paper and i am not sure if they will print that on the internet, the article even mentions that all of the war games Israel has are aimed at Egypt and that it was the revelation that Israel considered egypt as its number one threat to the Americans that lead to the US delaying F-15’s to egypt.

    P.s. the UAV was obviously detected since the Israeli’s lodged a complaint about it. but I think they were unable to hit it. the Scarab it self flys at 43k ft.

    I thought i read some where that EADS was going to upgrade the Polish mig-29’s for them to make them NATO compatible, supposed to have different engines avionics and certain other bits and bobs.

    EADS (formerly DaimlerChrysler Aerospace) is to upgrade 22 MiG-29 aircraft of the Polish Air Force. Modifications are needed to adapt the aircraft to NATO standards, prior to Poland’s entry into NATO. EADS has performed similar modifications to the MiG-29s of the former East German Air Force. EADS has joined with RAC-MiG to offer modernisation packages for the MiG-29, and has signed agreements with Romania and Bulgaria for product support and modernisation. EADS, Aerostar of Romania and Elbit of Israel have also launched an upgrade, MiG-29 Sniper, which includes modernisation and maintenance of the airframe and engines, and upgrades of the avionics with new Elbit digital mission computer and weapon systems, and installation of a glass cockpit.

    @shorty

    You working at Surrey Sattelites? Should do a history or the space program. I.e. the space suite and stuff.
