Evaluation of Experimental Radio-Meteorological Measurements Package (ERMMP) Antenna Installed on U-21A Wing,

Abstract

During the testing there were no observed changes in the lateral control characteristics of the U-21A. No tendency for aileron oscillation, buffet or feedback into the U-21A control system was noted. At airspeeds above 150 KCAS the 1/4 inch diameter antenna sensors vibrated approximately + or - one diameter and were bowed aft approximately 2 diameters from their static position. The lateral control pulses or steps did not cause any further excitation of the 1/4 inch antenna. Within the scope of this test the U-21A with ERMMP antenna installed can be operated within the flight envelope and operating limits of the current operator's manual.
