Measurements of tailplane and elevator effectiveness are reported for a 1/20th scale complete model of the Jindivik target aircraft. The model reflected the Mk.203B version of the full scale aircraft, the major features of which are as follows: short wing with Mk.8 fuel pods (with fins), nominal + 1 deg twisted flap, fixed ailerons drooped at 1 - 1/2 deg.: extended chord tailplane with a nominal setting of -1/2 deg. The tests included tailplane angles in the range -2 and 1/2 deg. to 3 and 1/2 deg. and elevator angles in the range -15 deg. to 10 deg for Mach numbers between 0.5 and 0.9. The aircraft is shown to be generally stable throughout the tested ranges, but several small areas of instability are noted. Tailplane and elevator angles to trim are also included and both are shown to increase rapidly for Mach numbers above 0.75. (Author)
