Project Description
SU-25 attack aircraft TECHNICAL DETAILS
The Su-25 has a conventional aerodynamic construction with a shoulder-mounted trapezoidal wing and a conventional tailplane and rudder. Various metals are used in the airframe’s construction: 60% aluminium, 19% steel, 13.5% titanium, 2% magnesium alloy and 5.5% other materials.
All versions of the Su-25 have a metal cantilever wing, a moderate sweep, a high aspect ratio and are equipped with high lift devices. The wing consists of two cantilever sections connected to a central torsion box, forming a single unit with the fuselage. The aerobrakes are housed in fairings at the end of each wing. Each wing is equipped with five attachment points for carrying the weapons, with the attachment points mounted on ribs and supporting spars. Each wing is also equipped with a five-section leading edge slat, a two-section flap and an aileron.
