Page 5 - Al matrices Impact failure modes of B/AI are proposed in an attempt to describe the mechanisms involved and to provide insight for maximizing impact resistance The impact strength of B/AI was significantly increased by proper selection of materials and processing The use of a ductile matrix and large diameter boron fibers gave the highest impact strengths.

Page 37 - The second control law employs primarily the elastic contribution of the wing and leads to large increases m the activated control effectiveness as compared with the basic control law The results indicate that flutter speed can be significantly increased (over 70 percent increase) and that the bending moment due to gust loading can be almost totally eliminated by a control system of about 10 to 20 percent span with reasonable control-surface rotations Author N76 28949*0 National Aeronautics and Space...
