It is clear that the cost of engine development programs has been increasing over the years. The time required to complete these programs has also increased, but this is not so clear - nor so dramatic - because the added time has been placed at the front end - with RD and demonstrator programs. Since these tend to reduce the risk of Full Scale Developments our assessment is that the total time required for engine development has not increased significantly. While we are not all certain that the increasing cost trend can be reversed - or even slowed down - we have described our views as to the cause and made recommendations to control the trend. Also identified are alternatives. In this regard the derivative engine approach is cited as having strong potential for significant reductions in both time and cost. It must therefore be carefully reviewed against the must have rather than the nice-to-do requirements of future programs.
