Sukhoi Su-28 Trainer
The Sukhoi Su-28 (also designated Su-25UT – Uchebno-Trenirovochnyy) is an advanced basic jet trainer, built on the basis of the Su-25UB as a private initiative by the Sukhoi design bureau. It is intended for technical skill, general flight and formation flying training. It is also used as a demonstrator of advanced aero-manouevres.
The Su-28 is a highly manouevrable and robust aircraft with the ability to perform take-off and landing with only one of its two engines running. The aircraft's engines can also run on a diesel-based fuel as opposed to more traditional aviation fuel. Like the MiG-29, it also has the ability to operate from unpaved runways while maintaining high reliability and a low maintenance requirement. In addition, the Su-28 can withstand heavy landings, allowing it to be more forgiving in the training role.
Range can be extended by up to four PTB-800 drop tanks, each of 800 litres capacity. 302 blue (above) carried all four whilst on static display at Farnborough in 1992 although only the inboard tanks can be seen in this image.
Differences between the Su-28 and its parent Su-25UB model include the absence of targeting systems, weapon-operating systems, internal guns and weapons-capable wing pylons. It also lacks armour protection for the engines, electronic countermeasures and any systems dedicated to ground-attack operations.
The apparently-flat plate seen bolted centrally on the nose is actually angled at about 60˚ from the vertical, with the lowest edge furthest to the rear. Combat-capable Su-25s have a clear window here, behind which are presumably targeting optics/lasers for weapons systems.
