The Kharkiv KhAI-1 (ХАІ-1) was an airliner produced in the Soviet Union in the early 1930s, unusual in that it was designed by students. An exceptionally clean design, the KhAI-1 was the first European passenger transport aircraft to feature retractable undercarriage, and boasted a top speed better than the fighter aircraft in service at the time. Some 40 KhAI-1s were operated by Aeroflot, but while a dedicated military version, the KhAI-1VV was developed and flown in prototype form, this did not enter production.
