dc.description.abstract	Resonance tests were made on a model delta aircraft to investigate the effect of stiffness changes of the leading- and trailing-edge spars on the frequencies and modes of vibration of the model. The results showed that, whereas considerable frequency changes were apparent, the general shape of the modes of vibration did not change significantly. A criterion of modal orthogonality proved to be very useful in checking the purity of the modes.	en_US
