    My god, enough already with the giant cut&paste repitition. These last couple of pages would fit in a few paragraphs without it.

    In what way?

    A single seat version of either jet would offer a far more capable platform then the Saeghe. Even in their twin seat form, both would kick the Saeghe’s butt at BVR and should at lease hold their own in WVR. If you add in goodies like HMS and latest gen Russian/Chinese AAMs then the Saeghe’s chances get even slimmer.

    A trainer typically uses virtual displays for radar in the modern day. I cannot imagine the L-15 having much room for a real one. And the Yak-130 should be totally outclassed in performance, allowing the Saeghe the option to engage in hornet nest range or otherwise.

    I would think L-15 and Yak-130 are both inferior to Saeghe for the purpose it is to be used.

    btw – the Yak-130 uses the plain DV-2, the non-afterburning version of the same engine. It couldn’t possibly be much help as its not much different overall than the non-afterburning J85 except for tighter fuel control.

    Call me stupid, but I do believe we have a fairly close match. Look at the chinese L-15 trainer’s outlets.

    The L-15 trainer is the only aircraft I can find using the DV-2F powerplant. The bubble cockpit design makes the L-15 look substantially fatter, but overall the engines seem to share relative dimensions.

    DV-2F is an option for the Yak-130 that supports afterburning to boost the dry static thrust from 5,500 pounds up to a wet 8,000 pounds apiece. They weigh around 1,400 pounds apiece, not including the gearbox. It has a fan diameter of 25.4 inches (65 cm) and an overall diameter of 40.8 inches (104 cm). Not sure what the length is, but the nonafterburning DV-2 is listed as 67.8 inches (172 cm).

    In comparison the GE J85-GE-21 is rated dry at 3,600 pounds and 5,000 pounds wet, with an overall diameter of 26.1 inches (663 cm) and a weight of 640 pounds apiece. So for a gain of roughly 1,520 pounds overall you’d gain a maximum theoretical thrust of 4,000 pounds dry and 6,000 pounds wet.

    Your specific fuel consumption moves from 1.240 lb/lbf hr dry and 2.130 lb/lbf hr wet to .588 lb/lbf hr dry to 2.280 lb/lbf hr wet. Airflow goes from 53 lb/s to 117 lb/s, so I’m guessing the Saeghe would need a radically changed inlet.

    Maybe its because of the cfm6 core?

    1983 Lebanon. Or were you not alive?

    And its to get Iran’s help in stopping the insurgency within Chechnya which is Iranian-backed. If the Chechnyans separatists lose Iranian money then the whole effort becomes increasingly more manageable to the Russians.

    vajt probably meant a single-engine considering the F-5G/F-20 were both officially single-engined.

    If Russians could get support from Iran for stopping Chechen rebels an engine swap was cheap in comparison to further military action against the terrorists. But the real point on my mind was to bring up losses of F-14’s to the Syrians. These carcasses were bombed to oblivion, but probably not before something got carried off.

    So what kind of solution would you suggest, dj?

    I always wondered if they shouldn’t of used two different wings, one for the attack version and one for a fighter. The attack wing could of afforded to be more straight. The fighter version could of been more exotic, perhaps even forward swept. Its not like the attack version wouldn’t still have air-to-air capabilities when needed to fill in the defensive gaps.

    They should quiet down the Bear’s engines if they are going to put any effort into the project.

    Wow, they are some old airframes. Surprised any avoided the scrappers.

    F-111A was a bomber after it was a fighter. The F-14A inherited its fighter role.

    Variable sweep is a perfectly good solution for certain missions. But today it seems nations are designing (or redesigning old) air superiority fighters and hanging bombs on them.

    Which seems ass backwards for most jets. Normally with new technology you start with bombers and only after some introduction move said tech to air superiority, then at the end of its useful life in air superiority you move it to ground attack. The vg wing moved to bombers only midway into the technology.

    I give no credibility to lasers as a static defense. Too easy to destroy the static location for the laser and/or its power handling equipment. And anything with that much power is going to emit some sort of electromagnetic radiation that is easy enough to triangulate. First sign of cloud cover over the site and its neutured by gps-guided cruise missiles.
