Abstract: FIELD: foundry. 
     SUBSTANCE: invention relates to continuous casting of metal and can be used at control of geometrical shape of crystallizer. First and second opposite side walls (210, 220) and first and second end walls (230, 240) extending between the side walls form a mold cavity. At least one of the first and second side walls comprises two or more contact areas, each of which is located at a distance from the other along the length of at least one of the first and second side walls between the first and second ends of the side walls. Each contact area can displace relative to the straight section between the first and second ends of the side walls in response to the force applied outside the crystallizer cavity. Displacement on first contact area relative to straight section differs from displacement on second contact area relative to straight section. Force on each of two or more contact areas changes curvature of at least one of first and second side walls between first end face and second end face of opposite side walls.

Abstract: FIELD: aircraft engineering.  
     SUBSTANCE: invention relates to the field of aviation, in particular to methods for rotating the lifting propellers of rotary-wing aircraft. The method for rotating the lifting propeller using at least one jet engine is that a mixture of gaseous fuel and an oxidizer is burned at the combustion site to produce a jet stream that creates thrust for the rotation of the lifting propeller. The combustion process is the process of detonation of a mixture of gaseous fuels and an oxidizer. In this case, the liquid fuel evaporates to a gaseous state before being transported to the combustion site, and the gaseous fuel is transported to the combustion site due to centrifugal forces generated by the rotating lifting propeller.  
     EFFECT: efficiency of the jet-driven rotor is improved by reducing energy consumption for preparing the mixture of fuel and oxidizer for combustion.
