Abstract

Using both simple analytical investigations and complex numerical simulations, we show that typical accelerations of an aircraft do not affect significantly its aeroelastic parameters. This suggests that flutter testing could be performed in accelerated flight, thereby reducing the cost and risk involved in determining the flutter envelopes of fighters. We illustrate this concept with numerical simulations for an F-16 fighter configuration and compare the obtained results with flight test data.
