IAR 79

The IAR 79 was a twin-engine bomber and military reconnaissance aircraft with a wood and metal structure that saw service in World War II built under licence in Brasov, Romania, by Industria Aeronautică Română

In May 1937, Romania ordered 24 Savoia-Marchetti SM.79B bombers powered by two Romanian-built IAR K14 engines.

This variant was designated SM-79B and equipped the 1st Bomber Group (71st and 72nd Bomber Squadron).

Second batch of aircraft were upgraded by replacing the IAR K14 engines with 1200 hp water cooled Junkers Jumo 211Da engines increasing the maximum speed from 350 km/h to 405 km/h.

Eight of these new airplanes were ordered in Italy.

They were designated JIS-79B (Jumo Italian S-79B). But they didn’t arrive until August 1941.

An additional 36 aircraft were license built in IAR factory in Brasov under designation IAR 79 JR (Jumo Român).

In the autumn of 1942, another order of 36 bombers was issued to the IAR factory.

They were upgraded by replacing the Junkers Jumo 211Da engine with new Junkers Jumo 211F, a 1400 HP engine.

The IAR.79 was a cantilever low-wing monoplane bi-motor, with a retractable taildragger undercarriage.

The fuselage of the IAR.79 was made of a welded tubular steel frame and covered with duralumin in the forward section, duralumin and plywood on the upper fuselage surface, and fabric on all other surfaces 

The wings were of all-wood construction, with the trailing edge flaps and leading-edge slats (Handley-Page type) to offset its relatively small size.

The internal structure was made of three spars, linked with cantilevers and a skin of plywood.

The wing had a dihedral of 2° 15′. 

Ailerons were capable of rotating through +13/-26° and were used together with the flaps in low-speed flight and in take-off.

Its capabilities were significantly greater than its predecessor, the SM.79, with over 1,850 kW (2,800 hp) available and a high wing loading that gave it characteristics not dissimilar to a large fighter.

The engines fitted to the main bomber version were two 750 kW (1000 hp) IAR K14 radials, equipped with variable-pitch, all-metal three-bladed propellers.

Speeds attained were around 430 km/h (270 mph) at 4,250 m (13,940 ft), with a relatively low practical ceiling of 6,500 m (21,330 ft). Cruise speed was 373 km/h (232 mph) at 5,000 m (16,400 ft), but the best cruise speed was 259 km/h/161 mph (60% power).

The landing was characterized by a 200 km/h (120 mph) final approach with the slats extended, slowing to 145 km/h (90 mph) with extension of flaps, and finally the run over the field with only 200 m (656 ft) needed to land (2,050 rpm, 644 Hg pressure).

With full power available and flaps set for take-off, the SM.79 could be airborne within 300 m (980 ft).
