From page 17...
... Propulsion in the context of the current ONR program applies to gas turbine engine technology for naval vehicle applications such as missiles and manned and unmanned rotary- and fixed-wing aircraft. The only technical connection between the two is that the propulsion engines mechanically drive the electrical generators in most air vehicles.

... None represent new ideas, but rather are part of the stepwise, long-term progression needed to develop new technology to the point that it can be adopted by gas turbine engine development programs with acceptable levels of technical risk. (Magnetic bearings, for example, represent a concept that has existed for several decades and has been demonstrated in an engine core as part of the IHPTET program.

... In addition, given the marked shift in emphasis to small UAVs/UCAVs and the need for extended-range munitions, the committee recommends that ONR consider reallocating the investment portfolio between large and small gas turbine engines. There is no balance between 6.1, 6.2, and 6.3 in propulsion since both the IHPTET program and the Navy have no direct 6.1 funding supporting gas turbine technology development.

... This area has received considerable attention because of the problem of aging civil aircraft. Recommendations 2001 ASSESSMENT OF THE OFFICE OF NAVAL RESEARCH'S AIRCRAFT TECHNOLOGY PROGRAM ONR should ensure that the program takes full advantage of other relevant work and focuses on the problems unique to naval aviation.
