The Ikarus 452 was an experimental jet aircraft built in Yugoslavia in 1953. It was a stubby mid-wing cantilever monoplane of pod-and-boom configuration, with twin jets mounted one atop the other at the rear of the fuselage nacelle, with separate intakes for the lower engine (in the wing roots) and the upper engine (on the sides of the rear fuselage). The twin tails and horizontal stabiliser were carried at the ends of booms that extended rearwards from the wings, with a short fin extending from the top of the rear fuselage to also meet the stabiliser. The flying surfaces were sharply swept, and construction throughout was of an experimental alloy.
