National Report Advisory Commitee for Aeronautics (NACA) Langley Field from September 1944.
This report highlights, curves and tests to support the different benefits of fighter aircraft engines equipped with an additional water injection.
The main conclusions are:
- The injection of water increases the octane number of the mixture.
- The water injection enables increasing the mean effective pressure with a reduced specific fuel consumption.
- The injection has a cooling effect of the internal engine parts (piston and cylinder).
- The injection of water does not allow fuel economy when the fuel is not used to its limits thermochemical.
- In extreme circumstances, the injected water can be diluted with oil lubrication and cause damage.
