P
assenger version of the SB high speed bomber. Aircraft was built in parallel with SB production steaming up, and faced no serious drawbacks. It used wing, tail and landing gear of the bomber. New fuselage provided room for ten seats, buffet, lavatory and luggage section. Excellent sound insulation, common and individual ventilation, heating system provided passenger with world class comfort, while rich cockpit equipment (including autopilot) guaranteed safe flights.
First flight (August 20, 1936) with M.M.Gromov on controls revealed excellent flight characteristics. On September 15 flight Moscow-Leningrad-Moscow was performed. In November-December ANT-35 was flown to Paris, where demonstrated on International Airshow.
The only requirement for series production was to increase passenger cabin height by 15cm. This was done in the second prototype (ANT-35bis) which was built in 1937-1939 under designation PS-35.
PS-35 lost competition to Li-2, which was slower but carried twice of payload with the same powerplant.
Eleven PS-35 were built, they served airlines Moscow-Lviv and Moscow-Odessa until year 1941.
