Abstract
Supersonic flow past oscillating cylindrical shells and
oscillating flat-plate cascades is analyzed using linearized
characteristics methods. Pressure distributions and generalized
aerodynamic forces are computed for arbitrary radius
to length ratios, axial and circumferential wave numbers,
Mach numbers, and reduced frequencies. Excellent agreement
is obtained with a previous solution of the complete unsteady
linearized potential equation by Dowell and Widnall
using Laplace transform techniques. Also, pressure distributions
are computed for flat-plate cascades with subsonic
leading edge locus for arbitrary solidity, stagger
angle, frequency, and interblade phase angle. For comparison,
a two-blade solution is developed using the method
of singularities. Good agreement is obtained for this
special case.
