The paper is concerned with a bending theory of a shallow right helicoidal shell subjected to a uniformly distributed load in the vertical direction. The general solutions of the shell are applicable to any prescribed boundary condition along radial and circumferential edges of the shell. New independent variables are introduced in order to obtain the fundamental differential equations with constant coefficients. Then analytical solutions of the equations have been sought by expanding the normal displacement and the stress function in the Fourier-series along the radial and circumferential directions. It has been found that not only the pitch of the shell but also the boundary conditoinns and the material properties are responsible for a significant difference of the mechanical behavior between right helicoidal shells and sector plates.
