Proceedings Papers

Paper presented at the SNAME 9th Propeller and Shafting Symposium, September 20–21, 2000
Paper Number: SNAME-PSS-2000-03
... A new method for the optimisation and design of Contra-Rotating Propellers (CRP) is presented in this paper. It is based on a Genetic Algorithm (GA) applied to a Vortex Lattice Method, used to compute the optimum spanwise distribution of circulation. chord length and thickness. Computation...

Paper presented at the SNAME Propellers '78 Symposium, May 24–25, 1978
Paper Number: SNAME-PSS-1978-012
... This paper describes first a design method for contra-rotating propellers using the momentum theory to determine the mutually induced velocities. Approximate formulae for these velocities have been worked out allowing both the design and the performance analysis of contra-rotating propellers...
