`
`THE MISSION OF AGARD
`
`According to its Charter, the mission of AGARD is to bring together the leading personalities of the NATO nations in
`the fields of science and technology relating to aerospace for the following purposes:
`
`- Recommending effective ways for the member nations to use their research and development capabilities for the
`common benefit of the NATO community;
`
`- Providing scientific and technical advice and assistance to the Military Committee in the field of aerospace research
`
`and development (with particular regard to its military application);
`
`- Continuously stimulating advances in the aerospace sciences relevant to strengthening the common defence posture;
`
`-
`
`Improving the co-operation among member nations in aerospace research and development;,
`
`- Exchange of scientific and technical information;
`
`- Providing assistance to member nations for the purpose of increasing their scientific and technical potential;
`
`- Rendering scientific and technical assistance, as requested, to other NATO bodies and to member nations in
`connection with research and development problems in the aerospace field.
`
`The highest authority within AGARD is the National Delegates Board consisting of officially appointed senior
`representatives from each member nation. The mission of AGARD is carried out through the Panels which are composed of
`experts appointed by the National Delegates, the Consultant and Exchange Programme and the Aerospace Applications
`Studies Programme. The results of AGARD work are reported to the member nations and the NATO Authorities through
`the AGARD series of publications of which this is one.
`
`Participation in AGARD activities is by invitation only and is normally limited to citizens of the NATO nations.
`
`The content of this publication has been reproduced
`directly from material supplied by AGARD or the authors.

`
`In recent years considerable experience with engine condition monitoring (ECM) has been accumulated, both in
`military and civil aircraft applications This Symposium has covered a wide range of applications to military aircraft and
`helicopters, to airline operations and to the use of aero derived gas turbines. The scope included user's experience with 0!
`board ECMI system and their integration into logistic systems; comparison of diagnostic methods for fault prediction;
`experimental results achieved by these methods; the impact of ECNIon future propulsion systems; and potential capabili
`arising from the availability of new diagnostic techniques. The emphasis of the Symposium was o'n operational experien4
`and current technological developments.
