摘要

The main part of this report is concerned with a trial to determine if there was any difference in the stop distance of a BAC 1-11 aircraft under wet runway conditions when fitted with three different modern anti-skid systems. The test runway was wetted by four water bowsers and the slipperyness of the surface at the time of the aircraft braked runs determined by a Mu-Meter friction trailer. A test with the Mu-Meter during a period of natural rain confirmed the similarity in runway friction between natural and bowser wetting methods. By comparing the aircraft stop distances at the Mu-Meter reading of .6 it was concluded that although the two more modern systems appeared to give the shorter distance, the difference was small and based on insufficient data points to give a high degree of confidence. The aircraft Braking Force Coefficient versus speed and Mu-Meter reading from one of the runs has been used to demonstrate the use of the method recommended in Ref 1 to determine the stop distance on the Standard Military Reference Wet Surface at the weight at which the aircraft was tested. The Appendices contain a method of deciding on the suitability of a test runway for aircraft/Mu-Meter braking trials using National and NATO standards, recommendations on how to conduct the trials and how to determine Mu-Meter speed/friction curves for the test surface. A brief description is given of a trial on a runway with a large amount of standing water. (Author)
