| Abstract | Generalized theoretical alcohol requirements for anti-icing gas turbine engines are presented and these are compared with experimental results for a number of engines.
It is concluded that turboprop engines may be anti- iced by spraying the amount of alcohol theoretically required through a suitable rotating distributor. Turbojets, on the other hand, require roughly twice the theoretical quantity at high alcohol flows when intake screens are used and a fixed distributor is employed and about three times the theoretical quantity at 1/3 of the maximum alcohol flow. Very preliminary results from rotating distributor tests on a turbojet suggest that about twice the theoretical quantity will anti-ice a screened engine to fairly low alcohol flows. It is predicted, however, that this latter figure could be reduced considerably by refinement of the distributor design.
Some notes on meteorological conditions, mechanical design, and various alcohols have been included. |
