The 1934 Tupolev ANT-27 Sevastopol crash occurred on Monday, April 15, 1934, when the MDR-4 prototype (Tupolev ANT-27) crashed in the bay of Sevastopol, killing all 4 airmen onboard. Which, some sources reported that the crash occurred on the 16th of April near Taganrog.[1][2]
Aircraft
[edit] |
The aircraft was an improved version of the Chyetverikov MDR-3. In the design bureau itself, the new aircraft was designated as ANT-27, while the military assigned the designation MDR-4. For a number of reasons, the construction of the first prototype was delayed by 4 months. On March 7, 1934, the first ANT-27 was completed, and three days later, it was delivered in disassembled form to Sevastopol for testing. On April 8, the aircraft made its first flight. It was piloted by T. V. Ryabenko and A. A. Volynsky.
Crash
[edit]On April 15[1], the ANT-27 was scheduled to conduct another test flight. It is worth noting that pilots often flew on the heavy German-made flying boat Dornier Wal, which due to their flat bottoms, had difficulty taking off from the water's surface. Therefore, when taking off in such machines, the crews used longitudinal rocking, believing that this would facilitate takeoff. On the ANT-27, such a technique was unnecessary due to its more keel-like bottom; however, the pilots habitually used rocking on it as well. It was noted that this aircraft reacted somewhat differently compared to the German flying boats. To understand this strange behavior, the designer Andrei Tupolev was summoned from Moscow, who witnessed the subsequent incident.[citation needed]
Tupolev went ahead in a boat to the start of the takeoff to get a closer look at the aircraft's transition to the "step" Redan. The aircraft began its takeoff, and when Tupolev saw that the pilots began applying the rocking technique, he tried to warn them by waving his hands not to do so. However, the crew did not notice this, and after accelerating in Kuglaya Bay on calm water to high speed, the ANT-27 moved out of the bay into the open sea, where there were high waves at that moment. Striking the first wave, the aircraft lifted into the air, then lowered its nose and crashed into the second wave. The struts of the central power unit could not withstand the impact and collapsed, causing the heavy engine to fall onto the cockpit.[citation needed] The incident resulted in the deaths of the head of the naval brigade KOSOS I. I. Pogossky, engineers G. S. Noskov and K. K. Sinelnikov, as well as the second pilot A. A. Volynsky.[1] The sources differ on who was piloting the aircraft at that moment. According to some sources, it was the deceased Volynsky.[citation needed] Other sources indicate that T. V. Ryabenko and D. N. Ilyinsky were also on board and piloted the aircraft, surviving the crash.[1]
Aftermath
[edit]After the crash, the name Pogossky was given to brigade No. 2, headed by A. P. Golubkov. The aircraft of this type produced later in the Tupolev design bureau were designated ANT-27bis. A total of 16 such machines were produced[1]
