Abstract:

The carriage of stores on wings significantly changes their dynamic characteristics and often adversely affects their flutter properties as a result of reduced wing frequencies and the introduction of critical frequency ratios together with inertia, elastic and aerodynamic coupling between loads. Adverse flutter characteristics and significantly lowered flutter speeds occur and these restrictions severely constrain the speed - altitude performance envelope that can be achieved by an aircraft. The variety of stores that can be carried on modern tactical airplanes generates a need to accurately evaluate the literally thousands of possible store combinations which can be carried by such aircraft. An AGARD Specialists Meeting held on 9 October 1974 had as its goal the presentation and discussion of latest information and procedures in use in the various NATO nations to solve the flutter problems associated with the carriage of external stores on wings. The proceedings of the specialists meeting are published as Conference Proceedings No. 162. This technical evaluation report assesses the conference, summarizes the nine presentations given, draws conclusions from the information exchanged and makes various recommendations concerning possible future efforts on the subject.
