TURBINE ENGINE WITH TRANSVERSE-FLOW HYDRAULIC TURBINES HAVING REDUCED TOTAL LIFT FORCE

摘要

The present invention relates to a turbine engine (55) comprising at least a first and a second lift type cross-flow turbine stack (53A, 53B). The axes of adjacent turbines in the first stack are connected by a first coupling device configured to compensate for spatial misalignment and the axes of adjacent turbines in the first stack are connected by a second coupling device configured to compensate for spatial misalignment. The turbine engine includes devices (46, 48) for supporting the first and second turbine stacks, and control devices (220A, 220B) configured to permanently maintain symmetry between the first and second turbine stacks , 224), which control device is configured to maintain the rotational speeds of the first and second turbine stacks at the same magnitude in the opposite direction.
