What is Flight tests of the lateral control characteristics of an F6F-3 airplane equipped with spring-tab ailerons about?

Flight tests were made to determine the lateral control characteristics of an F6F-3 airplane equipped with spring-tab ailerons, which were developed by the Grumman Aircraft Engineering Corp. and have been made a production installation on F6F airplanes. The flight tests showed that the spring-tab ailerons had desirably light stick forces and no tendency to overbalance. Although the tabs were not mass-balanced, no flutter tendencies were indicated at speeds up to 400 miles per hour, and any oscillations following abrupt control deflections were heavily damped. The spring-tab ailerons gave 80 percent higher values of effectiveness with a 30-pound stick force at 400 miles per hour than the original ailerons on the F6F-3 airplane. At speeds lower than 275 miles per hour, the spring-tab ailerons were less effective than the original ailberons because of restricted aileron travel as a result of the use of large deflection to deflect the spring Recommendations are made for modifications that would increase the aileron effectiveness at low speeds without affecting the lateral control at high speeds. The modifications consist of increasing the available aileron deflection and modifying the
