Flutter Clearance Tests on a Transavia PL-12/T-400 Skyfarmer,

Abstract

The Transavia T-400 Skyfarmer is the latest version of the twin-boom agricultural aircraft and incorporates several changes from the T-300 model previously tested. Changes which could affect the flutter characteristics are: a) Change of engine from 6 cylinder 300 horsepower to 8 cylinder 400 horsepower; b) Increase in length of tail booms by 750 mm; c) Increase in stub-wing span by 900 mm; d) Removal of the spring-tab from the elevators; and e) Addition of a dorsal stabilizer fin along each tail boom. A ground resonance test and subsequent flight tests were conducted on a Transavia T-400 Skyfarmer. The natural modes and frequencies of vibration were measured in the ground tests, and monitored during flight tests in which attempts were made to induce flutter. THe results of these tests are presented. Keywords: Flutter analysis; Aeroelasticity; Vibration tests; Utility aircraft; Airframes. (Australia).
