Tu-136 - a project of a regional passenger-and-freight aircraft powered by cryogenic fuel, developed by ANTK im. A.N. Tupolev in the 1990s. The main element of the system was the cryoplan project. The project was to use cryogenic fuels for small turboprop aircraft , which were supposed to be used in the regions of the North , Siberia and the Far East. For these purposes, at the Samara NTK them. Kuznetsov was finalizing the TV7-117 engine for the possibility of working on gas fuel. When choosing the aerodynamic configuration of the Tu-136, the layout features of the elements of the cryogenic fuel system on an airplane were taken into account. Hence, the use of a somewhat unconventional hollowed-out airplane scheme, logically combined with large-capacity fuel tanks . The design of the airframe is based on a structural-power scheme with maximum unloading of the wing and fuselage from the action of aerodynamic and mass forces. The Tu-136 is equipped with two TV7-117SF TVDs (each 3260 electric power) with six-bladed propellers with a diameter of 3.7 m. The aircraft engines can operate both on cryogenic fuels and on conventional aviation kerosene .
