AbstractAurora proposes to enhance the CH-53K helicopter drive shaft by reducing the weight and improving its ballistics survivability through the use of advanced composite materials. The new drive shaft will utilize carbon and aramid fibers, an advanced BMI resin system, and captured titanium end fittings in conjunction with existing metal components to reach these improved performance goals. A hybrid composite design also allows for material property tailoring to better meet the structural, dynamic, and environmental requirements imposed on the drive shaft. A composite drive shaft solution that is light weight, low cost, and provides operational performance after incurring ballistic damage would greatly benefit the overall value, performance, and survivability of military rotary wing assets.
