Abstract:

A series of tests were made with a powered model of the XC-142A airplane hovering over ground and over a water filled tank. Six component measurements were made of the forces and moments acting on the model, measurements were made of the water spray recirculated thru the outboard propeller and pictures were taken of the spray patterns developed. The force data showed a slight reduction in model normal force when hovering over water rather then the ground. There was considerable scatter in the moment data. Measurements of spray being recirculated thru the prop were found to be tolerable even at the most critical conditions. While there was considerable spray generated by the downwash, it was blown away from the model leaving the model relatively clear of spray. Author
