Further Refinement of the Subsonic Doublet-Lattice Method

The doublet-lattice method (DLM) is in use worldwide for flutter and dynamic response analyses of aircraft at subsonic speeds. The present paper develops a further refinement to extend its frequency limits for applications to higher frequency flutter, e.g for aeroservoelastic systems with high-frequ...

Zusammenfassung:	The doublet-lattice method (DLM) is in use worldwide for flutter and dynamic response analyses of aircraft at subsonic speeds. The present paper develops a further refinement to extend its frequency limits for applications to higher frequency flutter, e.g for aeroservoelastic systems with high-frequency control surfaces, and dynamic response, e.g., for short wavelength gusts.
