Redesign and shock analysis of HALIFAX class frigate gas turbine uptake structure
(Massachusetts Institute of Technology, 2008)
The gas turbine exhaust uptakes in the HALIFAX class frigates of the Canadian Navy have experienced thermally-induced fatigue cracking since soon after the commissioning of these ships. The uptake structure is heavily ...
Numerically-based ducted propeller design using vortex lattice lifting line theory
(Massachusetts Institute of Technology, 2008)
This thesis used vortex lattice lifting line theory to model an axisymmetrical-ducted propeller with no gap between the duct and the propeller. The theory required to model the duct and its interaction with the propeller ...
