Excerpt from Fire Retardant Ground Distribution Patterns From the CL-215 Air TankerThe drop pattern required by the fire conditions, and the characteristics of the delivery platform or aircraft, dictate the effective and minimum safe drop heights. The performance above this minimum safe drop height is related to the efficiency of the tank and gating system. Whether or not a particular system can deliver an effective drop pattern depends on the volume of retardant solution, the properties of the retard ant, and its flow rate upon release from the aircraft. Flow rates are related to the tank geometry and venting system, the size and shape of the gates, gate Opening speed and degree of obstruction, and the aircraft speed and flight envelope effect.Therefore, to improve the drop efficiency and safety, while updating the present air tanker fleet, emphasis must be placed on tank and gating system design, the proper ties of the fire retardant, and the relation between these two. The probable perform ance of proposed tank and gating systems must be known in order to assure selection of the best aerial attack systems and to optimize their performance. Therefore, the study reported here assessed the performance of the tank and gating system of the CL - 215. (it does not necessarily reflect on the performance of the CL-215 as an aerial platform, however.) Similarly, the properties of various retardants and their performance must be known. Thus, the study evaluated several retardants that are currently used.A series of test drops was carried out with the following specific objectives'About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
