Unsteady Water Channel.
Abstract
When an airplane undergoes maneuvering, the motion includes many modes: pitching, plunging, translation, acceleration and deceleration. The aerodynamics of the first three types of motion are well-documented. The effects of acceleration and deceleration on the aerodynamic forces of a wing have not been explored in depth because a specially designed unsteady testing facility is necessary. The present water channel is able to provide a wide variety of free stream conditions. The test section of the water channel measures 18-in. by 18-in. and has a maximum flow rate of 3 ft/sec. In addition, a rotating gate provides programmable unsteady flow velocities.
