Ocean EngineeringThe present paper presents the study of the application of air lubrication system (ALS) on DIS (Double Interceptor System) equipped hull to improve its performances. It was observed that without ventilation, the low-pressure area behind the forward interceptor leads to excessive downforce, reducing trim and rise and increasing wetted surface with ...
