An evaluation of worldwide transport aircraft fire experiences

This further study of turbine engined transport aircraft accidents has concentrated on 269 survivable accidents where there was either a post impact fire, major fuel spillage or an inflight fire involving the fuel. An evaluation has been made of the effects on the final fatality rate of such parameters as fuel type, aircraft type and size, load...

An assessment of the importance of the residual flexibility of neglected modes in the dynamical analysis of deformable aircraft

The mathematical framework for a unified approach to the dynamical problems of deformable aircraft, set up by Taylor in RAE Technical Report 71131, is used as the basis for a limited numerical investigation of the usefulness of the residual flexibility concept in truncated modal analyses. A finite-element model of a supersonic transport aircraft...

Prologue to the presentation of the mathematical foundation for an integrated approach to the dynamical problems of deformable aircraft

This paper sets the scene for a forthcoming report in which is presented the mathematical foundation for an integrated approach to aeroelastic problems, which is developed as a natural extension of classical (rigid-body) stability and control analysis to the deformable aircraft. Intended primarily for the non-specialist or newcomer to the...

Some experiments with fluidic devices in aviation kerosene

The College of Aeronautics was founded in 1946 and was granted university status in 1969 becoming the Cranfield Institute of Technology. In 1993 it changed its name to Cranfield University.

Determination of the configuration of a system of gyroscopes so as to align the resultant angular momentum in a given direction and maximise its magnitude

A system of four gyroscopes with fixed gimbal axes is required to provide a resultant angular momentum vector of maximum magnitude in a given direction. The determination of the directions in which the spin axes of the gyroscopes should be aligned to achieve this involves the maximisation of a non-linear function subject to non-linear...

A multiple frequency resonance testing technique for structures with rapidly changing dynamic characteristics

Methods of following, simultaneously, changes in several natural frequencies of a transiently heated structure are discussed. One method, using a multiplying technique, is discussed in some detail and the results of tests to prove the technique are presented

Analysis of flight loads recorded on Comet 4B aircraft by means of the fatigue load meter

Flight laad data collected by means of Fatigue Load Meters installed on Comet 4B aircraft operated by B.L.A. over Europe are presented in full, and analysed to determine whether a seasonal variation exists. It is concluded that there is no evidence of such a variation, probably due to the equipment of these aircraft with Cloud Collision Warning...

Annual variation of flight loads recorded on viscount aircraft by means of the fatigue load meter

Flight load data collected by means of Fatigue Load Meters from Viscount aircraft belonging to British European Airways and Trans-Australia Airlines are presented in full. An analysis is made to determine whether there is any regular annual varia tion of these flight loads (and consequently, it is believed, of the atmospheric turbulence which...

Development of a thin film heat-transfer gauge for shock-tube flows

The use of liquid platinum pairrt for the manufacture of thin film resistance thermometers has been investigated and films so made have been used in the measurement of heat transfer rates in the UTIA 2 x 2 inch strong shock tube. The heat transfer model was a circular cylinder placed normal _to the flow direction and having a thin film drawn at...
