The Tupolev DIP ( Russian Туполев ДИП ), factory designation ANT-29 (АНТ-29), was a heavy, twin-engine fighter aircraft from the mid-1930s. It was specially designed for testing the large-caliber 10.2 cm Kurschewski APK-100 cannon , and one copy was built. APK stands for Awiazionnaja Puschka, aircraft cannon.
development
After the APK cannon had been tested on the Tupolev I-4 at the beginning of the 1930s , Andrei Tupolew developed the I-12 and DIP models especially for further tests .
The construction of the DIP was carried out by Alexander Archangelski (at that time deputy chief designer at OKB Tupolev ) in the summer of 1932. The SB-2 medium bomber was also created using the basic plans . Due to the preference for the SB-2 program, however, the construction of the DIP was delayed until the beginning of 1935. On February 14 of the same year, Nikolai Blagin made the first flight of the model . The flight test was successfully completed. However, after the decision was made to use the RS-82 missile instead of the APK cannon in the armament of the Soviet air forces , the DIP project was also discontinued.
technical description
The DIP was made of all-metal construction. The fuselage had a square cross-section. The wings were arranged on the fuselage in a low wing configuration. The main landing gear was pulled into the rear engine nacelles in the wings. There was a grinding spur at the stern . The tail unit had a high elevator, which was braced with I-stems. The two APK cannons were on the left in the bow of the fuselage.
