Institution Royal Aircraft Establishment RAE Date 1963-04-30 Abstract Two methods for measuring tailplane loads have been tested in flight on a Hunter F.2 aircraft. One method used modified tailplane mountings which provided a satisfactory means of checking, in flight, the datums of their strain gauge bridges. Although hysteresis and other non-linearities in the load calibrations, together with fairly rapid temperature drift, limited the measuring system's usefulness in the flight tests, it appears that, with refinements in design, it should offer a good method for measuring absolute tail loads. The second measuring system, using shear strain gauges attached to the fuselage sides ahead of the tailplane, gave suitable load calibrations but was subject to considerable temperature drift. Reasonable agreement was obtained between the two systems, in incremental changes in aerodynamic load, over short time intervals (less than 30 seconds). In all cases the maximum loads measured were weIl below the structural strength limitations of the aircraft.
