摘要：	Results of a research program to determine the impact of towing transport airplanes at Boston-Logan Airport are presented. This study includes the measurement of actual towing loads during airline operations with the L-1011 at Los Angeles International Airport and Dorval, Quebec. The measured towing loads were obtained with an instrumented towbar and portable data recording package. Towing loads were also measured during controlled test conditions at Palmdale using the flight-test L-1011 airplane. A fatigue load spectrum representing ground maneuvering including the effects of extended towing was developed. Stress analysis of the nose landing gear and back-up structure was performed using the load spectrum representing extended towing at Boston-Logan. The results indicate that the proposed extended towing operations do not cause a reduction of fatigue life of the nose gear to below the design life for the L-1011. A discussion of alternate towing concepts is presented, and limiting conditions are defined to ensure acceptable operational safety during extended towing. (Author)
