Development of a Model Technique for Investigating the Performance of Soft-Ground Arresters for Aircraft

چکیده
SUMMARY This Report describes work undertaken in an attempt to establish the feasibility of using models to investigate the performance of gravel arresters for aircraft. The experiments were designed using the techniques of physical similarity and dimensional analysis, Tests were carried out with 1:9.3 scale models of Lightning and Canberra aircraft in two types of sand, and the results compared with those obtained in earlier full scale experiments. Despite difficulties in scaling some soil parameters, these results showed that the distance required to stop in the gravel bed for a given entry speed could be predicted with an accuracy of +lO to 15%. It is concluded that model experiments based on this work would allow the feasibility of gravel arresters for use by larger aircraft to be established.
