Construction

The Ił-2 is a typical ground-attack aircraft. Single-engine, self-supporting low-wing, mixed construction. Good armed and armored. There were single-seat and two-seat varieties. In the two-seat variant, the second crewman was the rear shooter. In the Polish Army, single-seat variety was not used.


The wings are technologically divided into three parts; center wing and two attached wings. The center wing in the interior had a bomb chamber. The outermost ends of the center wing had main landing gear chambers and a mechanism for its concealment.

The fuselage is technologically divided into two parts. The front engine began with the fuel tank and crew cabin behind. The critical elements of the machine were armored. Among them; engine, fuel tank, pilot cabin, oil coolers and engine coolant. The armor is made of thick steel plates, joined by rivets or screws.

It was only after the war that all aircrafts were equipped with radio stations in Polish regiments. There was no fire protection installation. Aircrafts did not have any lighting, including anti-collision. Only some clocks on the pilot's instrument panel were highlighted. It was only later that the reflector was mounted in the leading edge of the left wing. The aircraft did not have throwaway chairs. The crew had parachute seats.
