The IAR 16 was a low-wing monoplane fighter designed in Romania in 1934. DevelopmentDeveloped in parallel with the I.A.R. 15, the model '16' featured for the first time an all-metal airframe structure, covered with duralumin sheets, plywood and fabric. It resembled the I.A.R. 14 more closely than the I.A.R. 15, being inferior to the latter. The fuselage outlines followed the '14's, as did the wings, although their area was increased to 20.30 m². The tail section, as usual, was redesigned, the rear part this time becoming rounded. The two-strut undercarriage of the I.A.R. 14 was retained as well, and the tailskid appeared again. A new British radial engine, the Bristol Mercury IV S2, of maximum 560 h.p. (418 kW) output at 4,500 m, was experimented with. The powerplant was covered with a narrow Townend ring and individual exhaust pipes were fitted to each of the nine cylinders. The typical feature of this model was a large propeller cone fitted to a Bristol-made two-blade wooden airscrew. Due to the larger wings and all-metal fuselage structure the empty weight increased to 1,430 kg, giving a relatively high, 70.14 kg/m² wing load, that increased further during flight, taking also into consideration that the all-up weight was 1,650 kg. The usual armament, comprising two 7.7 mm Vickers machine gun Operational historyThe I.A.R. 16, first flown in 1934, remained in prototype stage. Its only significant achievement was the improvement of Romania's national altitude record. Piloted by Locotenent aviator Papana, on 16 July 1935, the I.A.R. 16, featuring an enclosed cockpit, took off from Pipera airfield at 17.48 p.m. 47 minutes later it established a new altitude of 11,631 m (at that time, the world altitude record was held by the Italian Cdr. R. Donati, who reached 14,433 m on 11 April 1934, while flying a Caproni 161), beating the previous 10,518 m set up by the late Romeo Popescu. The prototype was still seen in 1935-1936 at various air shows, where Alex. Papana performed high-level aerobatics to the delight of the spectators. Operators
