INFLATABLE VERTICAL FLOAT SYSTEM. PHASE I REPORT
Abstract
This proposed program will put to practical demonstration the concept of seaplane open ocean ASW operation. The HRV is an approximate 1/3 model scale representation of the P5 seaplane. It is equipped with a hydrofoil and has satisfactorily demonstrated take off and landing in seas three times the wave height permissible with the basic hull. Then with the incorporation of the Inflatable Vertical Float System, the HRV will have open ocean seakeeping capability and thus be a complete open ocean seaplane. The overall float system is shown. Initially, design goals were established and all were achieved within the scope of the study. These were, a system weight of 400 lbs or less, a 30 second retraction or extension cycle, capability to move through the water at 6 knots, identical float construction and size, and inflation system capability for two deployment-retraction cycles. The inflatable Vertical Float System is made up of a central telescoping column which supports an accordion type flotation bag. Local intermediate ribs are provided to maintain the cross sectional shape and take any torsional loads. Extension of the Inflatable Vertical Float System is accomplished by a single 2000 psig nitrogen storage bottle and associated pneumatic system. Control is provided at the pilot station through two flow control valves which regulate wing and hull float inflation. The operating pressure for the Inflatable Float System is 5 psig.
