A method and apparatus for controlling fluidic torque in a downhole tool is provided. One or more rotatable components of the downhole tool comprise a deformable material, such as rubber or SMA, selectively deformable in response to the flow of fluid through the downhole tool. The rotatable components may include a rotor and/or a turbine of a generator in the downhole tool. Non-rotatable components, such as the stator of the generator, may also be deformable. The rotor, the stator, and/or turbine may comprise a deformable material capable of selectively deforming in response to the flow of drilling mud through the generator. The desired deformation and/or the desired torque may be controlled by adjusting the parameters of the components.

Deformable blades for downhole applications in a wellbore

A method and apparatus for use in a wellbore includes explosive components, a housing containing the explosive components, and at least one protection barrier mounted on the housing to reduce transmissibility of an external force load to the housing. The explosive components array include shaped charges and detonating cords for use in perforating guns.
