UNDULATING PLATE TYPE PROPELLER: THE TWO-DIMENSIONAL IDEAL CASE

The motion of a two-dimensional flexible undulating plate in an incompressible ideal fluid flow is investigated. Employing an iterative numerical technique the motion of the plate and the hydrodynamic pressure distribution are found together with the resulting thrust or drag. The power input is calculated from the work of the exciting force per cycle, and the propulsive efficiency is defined in terms of thrust, free-stream velocity, and power input. For a given plate configuration in the frequency ranges studied, the propulsive efficiency is dependent on the reduced frequency only and reaches 50 percent. Plans for the continuation of this investigation are indicated.
