Abstract:

The aerodynamic feasibility of using wraparound lifting, stabilizing, and controlling surfaces on tube-launched bank-to-turn missile configurations is established by wind tunnel tests at high subsonic speeds. Test results show that the stability and control characteristics of a wraparound-surface configuration are as good or better than those of an equivalent planar-surface configuration. Predictions based on planar surfaces agree well with test results when surface-to-surface interference is not present. An improved prediction method for tail efficiency of wraparound-surface configurations is shown. Several configurational design preferences are indicated by the test results, including high wings with concave side windward, horizontal tails mounted with their concave side windward when in the undeflected position, and a windward directional stabilizer.
