(November 2016) (Learn how and when to remove this message) Ikarus 452 General information Type Research aircraft National origin Yugoslavia Manufacturer Ikarus Designer Dragoljub Beslin Number built 2 History First flight 24 July 1953 The **Ikarus 452M (B-452-2)** was a [Yugoslav](/source/Yugoslavia) [experimental aircraft](/source/Experimental_aircraft) first revealed in 1953. It was [Yugoslavia’s](/source/Socialist_Federal_Republic_of_Yugoslavia) first [swept-wing](/source/Swept_wing) light [jet](/source/Jet_aircraft) [fighter-interceptor](/source/Interceptor_aircraft). The all-metal aircraft featured retractable nose-wheel [landing gear](/source/Landing_gear) and was the first to incorporate a domestically produced light metal [alloy](/source/Alloy) for its [fuselage](/source/Fuselage) skin.[1] A distinctive aspect of the design was its [twin-fin tail unit](/source/Twin-boom_aircraft), an uncommon feature in Yugoslav aviation. The [fins](/source/Stabilizer_(aeronautics)) were mounted on beams extending from the wings and connected by a V-shaped [stabilizer](/source/Stabilizer_(aeronautics)). The aircraft had a 36º wing sweep, with plans to add [slats](/source/Leading-edge_slat) for improved performance. It was powered by two [Palas 056A](https://en.wikipedia.org/w/index.php?title=Palas_056A&action=edit&redlink=1) [turbojet](/source/Turbojet) engines arranged vertically in the fuselage, each fed by separate air [intakes](/source/Intake). As a [technology demonstrator](/source/Technology_demonstration), its [armament](/source/Weapon) was minimal, consisting of two [12.7mm](/source/12_mm_caliber) [Browning machine guns](/source/M2_Browning).[1] It was publicly revealed on April 30, 1953. However, a [test flight](/source/Flight_test) on July 24 ended in an [emergency landing](/source/Emergency_landing) due to [fuel system](/source/Aircraft_fuel_system) failure, severely damaging the aircraft and injuring the [test pilot](/source/Test_pilot).[1] To address inadequate engine [thrust](/source/Thrust), a three-engine variant (B-452-3) was proposed, with upgraded armament, but it remained at the design stage. A later iteration, the B-452-4, incorporated a more powerful [Turbomeca Marbore II](/source/Turbomeca_Marbor%C3%A9) [engine](/source/Jet_engine), an enlarged [airframe](/source/Airframe), and twin [20mm](/source/20_mm_caliber) [cannons](/source/Autocannon). Intended for both [interception](/source/Interceptor_aircraft) and [ground attack](/source/Close_air_support), it was designed to carry [air-to-surface](/source/Air-to-surface_missile) [high-velocity aircraft rockets](/source/High_Velocity_Aircraft_Rocket) (HVARs). Despite its modern concept, the project was ultimately shelved in favor of the B-12 interceptor.[1] Results of the experimental programme provided a basis for the production of the [Soko Galeb](/source/Soko_Galeb).[*[citation needed](https://en.wikipedia.org/wiki/Wikipedia:Citation_needed)*] ## Specifications **General characteristics** - **Crew:** One pilot - **Length:** 5.97 m (19 ft 7 in) - **Wingspan:** 5.25 m (17 ft 2 in) - **Height:** 1.77 m (5 ft 9 in) - **Gross weight:** 1,100 kg (2,420 lb) - **Powerplant:** 2 × [Turbomeca Palas](/source/Turbomeca_Palas) 056A , 1.5 kN (330 lbf) thrust each **Performance** - **Maximum speed:** 780 km/h (466 mph, 405 kn) - **Endurance:** 1 hours 15 minutes **Armament** - 4 x 12.7mm [M3 Browning](/source/M3_Browning) machine guns (two nose gun ports per side) ## See also - [Aviation portal](https://en.wikipedia.org/wiki/Portal:Aviation) - [Ikarus 451M](/source/Ikarus_451) (first domestically-built Yugoslav jet aircraft) - [Ikarus 453](https://translate.google.com/translate?hl=en&sl=ru&u=http://www.airwar.ru/enc/xplane/453.html&sa=X&oi=translate&resnum=1&ct=result&prev=/search%3Fq%3Dhttp://www.airwar.ru/enc/xplane/453.html%26hl%3Den%26sa%3DG) ## References 1. ^ [***a***](#cite_ref-:0_1-0) [***b***](#cite_ref-:0_1-1) [***c***](#cite_ref-:0_1-2) [***d***](#cite_ref-:0_1-3) ["Ikarus 452"](https://www-airwar-ru.translate.goog/enc/xplane/452.html?_x_tr_sch=http&_x_tr_sl=ru&_x_tr_tl=en&_x_tr_hl=en). - Taylor, Michael J.
