The Hover Research Facility, a new experimental facility, is designed to study the flowfields generated by hovering VTOL aircraft and helicopters. Water is used as the working medium because of its inherent advantages in flow visualization and laser Doppler velocimeter (LDV) measurements. Applications of the HRF include: (1) experimental investigation of twin-jet impingement flow with application to VTOL aircraft; (2) visualization of the flowfield around a fully contoured, model supersonic fighter/attack short-take-off and vertical landing (STOVL) aircraft; and (3) performance testing of a No Tail Rotor (NOTAR) helicopter in hover mode by use of a scaled model. Flow-visualization and quantitative LDV data on these experiments are presented.
