The paper describes an investigation of the effect of structural damping in the torsion mode on wing flutter with the object of finding circumstances in which damping reduces the flutter speed. The drop in flutter speed ...

Tailplane flutter is investigated theoretically for the following semi-rigid modes : (i) tailplane bending, frequency ω1; (ii) tailplane torsion, frequency ω2; (iii) tailplane rotation, frequency ω3; (iv) fuselage bending ...

This Paper attempts to give some guidance on the question, of how best to approximate to an aircraft with an asymmetric elevator control for the purpose of flutter calculations. Two examples of asymmetric controls that ...

A typical wing-aileron combination is taken and ternary flutter calculations between wing bending, wing torsion and aileron rotation are described. The results are plotted as graphs of flutter speed against aileron frequency ...

Analytical solutions are derived for a class of axisymmetric base flows with heat addition. The assumed upstream conditions are non-uniform in velocity and temperature, which vary with r in spherical polar coordinates (r, ...

The arc cross section is supposed to be a region in which heat is supplied to a continuous stream and in which a body force acts. Pressure variations are assumed small so that incompressible potential flow methods can be ...
