A comparative study into the coking resistivity of swirlplates with various surface finishes

Approved for public release; distribution is unlimited === Gas turbine nozzle swirlplates used in the T56-A-427 engines of the E-2C Hawkeye aircraft were tested for their resistivity to fuel deposit formation, or 'coking'. The coking occurred after the engines were shut down due to the fue...

The coking occurred after the engines were shut down due to the fuel trapped in the line and temperature ranges present at the nozzle tip. As the coke built up, the holes in the swirlplate clogged and the aircraft required intensive servicing. The search for alternative solutions led to the possibility of using swirlplates that had been polished or coated in an attempt to reduce the coking rates. Several swirlplates surface finishes were investigated 2012-08-09T19:18:50Z 2012-08-09T19:18:50Z 1996-06 Thesis http://hdl.handle.net/10945/8111 en_US Monterey, California. Naval Postgraduate School
