Research On Systemic Performance Of Hovercraft Gas Turbine Propulsion

Hovercraft is a kind of high-powered watercraft. The propulsion system of hovercraft concludes mainframe, power transfer device, thruster, air propeller installation, and assistant system. As far as it goes, the technique for gas turbine used as power set is quite behind developed countries. So the studies of the hovercraft propulsion system using gas turbine is very important, especially it's dynamic characteristics. Three-spool gas turbine is a complex multiple input and output system, it is necessary to study it's dynamic performance, such as start-up accelerate, decelerate and screw troubled when on sail, helping improve reliability and flexibility of gas turbine.This dissertation analyzes the characteristic of propulsion system, including gas turbine, air propeller and fan. And doing analysis on the...
