Creation History
By order of the NKAP No. 358 dated May 27, 1944, Myasishchev Design Bureau was tasked with designing, building in duplicate and presenting for state tests in December 1944 a twin-engine high-speed bomber with VK-108 engines, with a maximum flight speed of 6,000 m at a height of 700 km / h and a range of 2000 km with 1000 kg of bombs inside the fuselage. Work began in the summer of 1944. The design was based on the Pe-2 I scheme with an increased fuselage bomb bay and more powerful, by 150-200 hp, VK-108 engines equipped with four-bladed VISH-108L-20 screws [1] .
General Information
The aircraft immediately began to design in three versions [2] :
- VM-16 ( Vladimir Myasishchev , project No. 16) - double for horizontal bombardments;
- VM-17 - dive with brake grids under the wing and the third crew member;
- VM-18 - four-seater with increased bomb load.
- VM-17 - dive with brake grids under the wing and the third crew member;
All three options were designated as DB-108 aircraft (a day bomber with VK-10V engines). Their design was all-metal and well adapted for mass production, had a three-leg chassis with a tail wheel and spaced tail unit.
To carry out normal take-off with maximum load or to reduce the take-off length at normal take-off weight, the BM-17 and VM-18 were equipped with underwing installation from solid fuel rocket launch boosters.
The first VM-16 was built by December 30, 1944 and submitted for testing. They took place from January to June 1945. In June 1945, the BM-17 dive was made, and after it the VM-18 [3] .
In connection with the end of the war, the plan for the mass production of these aircraft was withdrawn, and the flight test program remained incomplete.
