Semi‐Articulated Bogie Undercarriage Landing Performance: Analysis of a Type Used on Large Aircraft

Abstract

IN recent years the bogie type of multi‐wheel undercarriage has been introduced on the medium and heavy range of aircraft. The trend began because of the necessity of keeping runway loadings to a minimum and the difficulty of stowing a large diameter single wheel in the wing or fuselage during flight. By spreading the main undercarriage ground reaction through two, four or more wheels, existing runways are able to accommodate heavier aircraft, while faster operational flight speeds have resulted in relatively thinner wing sections aggravating the stowage problem of the undercarriage. The interpretation of the bogie into practical undercarriages with their manifold performance duties has led to several types of mechanisms each with distinctive dynamical features. One such mechanism is the semi‐articulated bogie type and its general features have been previously described, The claims made for this undercarriage have been substantiated through several years of successful operational experience. Since this particular arrangement has obvious future applications both as a twin‐ or multi‐wheel version and, as it possesses characteristic dynamical features, it is considered appropriate to place on record the analysis of its landing performance.
