Su-11/Su-13Fighter-BomberSukhoy![]()
At the end of August, in parallel with the factory tests, flight tests of the TR-1 engine began under a separate program. On tests, at values of M = 0.71, the Su-11 had a tendency to dive, accompanied by a drop in loads on the aircraft control stick. In February 1948, the tests were completed. The flight test report concluded that: "The main performance data of the Su-11 aircraft with two TR-1s, obtained during the factory flight tests, correspond to the calculated data. The absence of TR-1A engines and the insufficient effect of TsAGI recommendations adopted to improve the aircraft's behavior at speeds corresponding to a large number of M make it impractical to further refine the aircraft. .... " In mid-1947, a draft design of a modified Su-11 aircraft with two Dervent-V engines (a domestic analogue of the RD-500) was developed, which received the designation Su-13 in correspondence. However, due to the lack of stocks of production facilities at plant No. 134, the construction of the Su-13 practically did not begin. |
