Studies have been performed to identify the key areas and cost of research that will reduce the cost of operation of helicopters through reduction of energy consumption, increased performance, and reduction of maintenance. The basic analyses were made for a large passenger helicopter, with subsequent studies considering applicability to all sizes. These study results were then applied to the existing and projected U.S./Canada helicopter fleet to compare the cost of research to the dollars saved as a result of that research. These comparisons show that research costs to reduce energy and lower maintenance have payback periods of less than one year, either as higher return to the operator or as lower rental price to the customer.
