Abstract:

A series of turning maneuvers was conducted with the instrumented XR-3 SES testcraft to determine the domain of differential drag experienced by the bow seal. Data is presented showing the difference in total drag experienced by the inboard and the outboard portions of the bow seal during turns at various testcraft velocities. A brief introduction to SES terminology and a summary description of the testcraft, its instrumentation and data reduction facilities are included. Results show a fluctuation of the differential drag forces experienced as testcraft velocity increases, especially at high rates of turn. Author
