Abstract:

The report is concerned with various techniques that might be used to achieve high quality vibration isolation for equipment mounted on a helicopter. Of specific interest is the problem of reducing the rotor induced vibration of externally mounted rocket launchers. Three schemes for reducing rocket launcher vibrations are proposed. The first scheme is along the lines of traditional vibration isolation methods. The second scheme uses a novel device called a vibration absorber which theoretically can completely eliminate sinusoidal launcher vibrations - provided the vibration frequencies are constant. The third proposed scheme is somewhat newer, and more exotic, and leads to what can be called an active vibration absorber. Author
