Tests, using small scale models of the Curtiss-Wright X-100 and X-19 aircraft, have been carried out to investigate the disturbance and spray caused by VTOL aircraft hovering above water. Full scale disc loadings in the range 20 to 70 lb.sq.ft. were represented. Correlation of the model test results with full scale testing of the X-100 airplane over water at a disc loading of 23 lb. sq.ft. and height of 21 feet show excellent agreement. Downwash effects on objects floating below the X-19 model were also demonstrated. Spray is shown to rise to considerable heights at the higher disc loadings with the models close to the water surface, and floating objects may be subjected to severe buffeting under these conditions.
