Wind flow on the flight deck of a F-110 frigate

Helicopter operations in frigate-type boats can be critical depending on the sea and wind conditions. Due to the non-steadiness and wide variations of the mean velocity, the flight envelope is limited, being the approach to the flight deck one of the most complex and risky operations a helicopter can perform. Usually, the flight deck in the frigates is located in the stern. As a consequence, the wind flow in the surroundings of the flight deck is highly conditioned by the wake generated by the freeboard of the boat. This wake is highly turbulent and full of strong vortexes. These vortexes depend on the geometry of the boat upstream the flight deck. The correct characterization of this complex flow is related to the safety of the operation of the aircraft and allows to set the limits in which the deck can be operative or be certified. In this work, some partial results of an extensive wind tunnel test campaign are presented. In this campaign, a model of the F-110 frigate has been tested. The aim is to characterize the flow in the surroundings of the flight deck of the frigate. For that, visualization tests with wool tufts and smoke, hot wire anemometry and particle image velocimetry (PIV) have been performed. All the tests have been done in the experimental aerodynamics facilities of the Instituto Universitario ?Ignacio Da Riva?, belonging to the Universidad Politécnica de Madrid. Based on the information obtained in the tests, small modifications in the freeboard are suggested, in order to optimize the flow in the flight deck, which can make the approach operation easier for the pilots.
