VEF I-15
In the summer of 1938, the Latvian aircraft designer Kārlis Irbītis, working at the Valsts Elektrotehniskā Fabrika (VEF) at Riga commenced design of a single-seat advanced trainer as a follow on to his earlier, similar VEF I-14 aircraft.
The I-15 was a low-winged monoplane of all-wooden construction, powered by a single de Havilland Gipsy Six air-cooled engine, and fitted with a fixed tailwheel undercarriage.
The design of the I-15 was in general similar to the earlier I-14, but it was carried out taking into account the requirements of the Air Force of Latvia. The fuselage and wing were slightly redesigned, a new de Havilland Gipsy Six-I engine (200 hp) was installed with a two-bladed fixed-pitch wooden propeller.
In April 1939, the first prototype, the I-15a with the registration number "190", made its maiden flight, while a second prototype, the I-15b ("191"), was powered by a 220 hp (167 kW) Gypsy Six II engine driving a variable-pitch propeller, and armed with a single synchronised machine gun followed, this demonstrating improved performance, increasing speed from 314 to 330 km / h.
The two I-15 prototypes were transferred to the Latvian Air Force for use as advanced trainers, while a further two aircraft, to be designated I-15bis and powered by Hispano-Suiza 6 Mb engines were ordered by the Air Force, but on 17 June 1940, the Soviet Union occupied Latvia, ordering all aviation related work to be stopped.
Work on I-15 was discontinued in 1940, when a more advanced I-16 fighter was successfully tested.
