Project Description
SU-25 attack aircraft TECHNICAL DETAILS
The Su-25 has a conventional aerodynamic layout with a shoulder-mounted trapezoidal wing and traditional tail and rudder. Several metals are used in the construction of the airframe: 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, moderate sweep, high aspect ratio, and are equipped with high-lift devices. The wing consists of two cantilever sections attached to a central torsion box, forming a single unit with the fuselage. The airbrakes are housed in fairings at the end of each wing. Each wing has five attachment points for carrying weapons, the attachment points being mounted on supporting ribs and spars. Each wing also has a five-section leading edge slat, a two-section flap and an aileron.
