Tomashevich 110

Dmitrii L Tomashevich was a deputy of Nikolai Polikarpov and responsible for the I-180, the failure of which led to his imprisonment. Transferred from Special Prison KB-29 to Kulomzino, a suburb of Omsk, in October 1941, Tomashevich established his own project bureau and developed a single-seat fighter referred to simply as Samolet (Aircraft) 110. Placing emphasis on suitability for dispersed manufacture, largely by semiskilled and unskilled labour, and ease of repair and maintenance under primitive field conditions, the 110 was of mixed construction, with a two-spar wooden wing and welded steel-tube fuselage. The wings, fixed tail surfaces and aft fuselage had Bakelite ply, or shpon, skinning, the remainder of the fuselage being covered by light alloy. The engine was a Klimov M-107P 12-cylinder Vee-type rated at 1,400hp and armament comprised one 20mm cannon and two 12.7mm machine guns. The first prototype was flown in December 1942, but the 110 proved substantially overweight and the insufficiently-developed Klimov engine proved unreliable. Furthermore, series production of another fighter at that stage in the conflict was impracticable, and, in consequence, development was discontinued.
