We're back with Cessna 152. Now, we're talking about the Air Frame. What is it like in the Cessna 152 ?
The 152's airframe is an all metal construction. It is primarily aluminium 2024-T3 alloy, although some components such as wing tips and fairings are made from fibreglass. The fuselage is a semi-monocquous structure: it has vertical bulkheads and frames joined by longerons which run the length of the fuselage. The metal skin of the aircraft is riveted, which allows loads to be spread out over the structure. The wings are of a strut-braced design and have a 1 degree dihedral angle. The tapered (outboard) portion of each wing has one degree of washout (the chord of the tip section has one degree lower angle of attack than the chord at the end of the constant-width section). This allows greater aileron effectiveness during a stall, although it is much less than the 3 degrees used in Cessna 172 wings.
