Rotor solidity is a dimensionless quantity used in design and analysis of rotorcraft, propellers and wind turbines.Rotor solidity is a function of the aspect ratio and number of blades in the rotor and is widely used as a parameter for ensuring geometric similarity in rotorcraft experiments.
Solidity was proposed in August 2014 by Gavin Wood [13] [non-primary source needed] The language was later developed by the Ethereum project's Solidity team, led by Christian Reitwiessner. Solidity is the primary language used to develop smart contracts for Ethereum as well as other private blockchains , such as the enterprise-oriented ...
Blade solidity affects various turbomachinery parameters, so to vary those parameters, one needs to vary blade solidity. However, there are some limitations imposed by aspect ratio (span/chord) and pitch. If an impeller has only a few blades (i.e a large pitch), it will result in less lift force and in a similar manner for more blades (i.e ...
