- 30 DISCUSSION ON THE EFFECTS OF JET Discussion The Authors introduced the Paper with aid of a film illustrating the effects of a Vampire jet, operating at different outputs, on various kinds of surfacing. Mr K. C. Mann said that only co-operation between aircraft designers and airfield designers would prevent the problem which had arisen through the adoption by the aircraft industry of jet engines from becoming almost insoluble. If the aircraft designers were to accentuate still further the trend that was shown in Fig. 3 (a) (Attacker) by designing aircraft with even greater downward inclination of the jet, he thought that nothing short of some expensive refractory material would be necessary on the runways ; and in point of fact the jet people would put themselves out of business, because it would be too expensive to put aircraft on the ground ! The film had shown that the Vampire's jet had devastating effects...

- 88 DISCUSSION ON OVERHAUL REPAIR 0)' AND Discussion The Chairman, in proposing a vote of thanks to theAuthor, said that those responsible for the maintenance of dock gates realized that that was not just another branch of engineering but was, in many ways, a science of its own-especially in viewof the costs involved. As an example, the contract figure for a pair of gates built in 1945 had been f38,759, and the cost of the site-work f15,761, making a total of f54,520. A current contract, let within the past few months, for a pair `of gates of similar size, showed a big difference...

- 140 DISCUSSION ON l3kIDGE tNVESTIGATION, Discussion ' Mr W. E. Gelson first remarked upon the range of stress to which the wrought-iron specimens had been subjected in the 1936 fatigue tests. The range of 5'7.5 tons per square inch (see p. 118) was a figure which good wrought iron of the period might be expected to withstand. He then referred to the calculation of horizontal deflexion in Appendix 11. Since the bridges wereof deck type, considerable differencein lateral deflcxion due to centrifugal force was to be expected between top and bottom flanges...

Judging by references to it in novels, radio talks, newspaper articles, or in ordinary conversation, railway architecture seems to consist of grimy, ill-lit, draughty platforms with leaking roofs, dingy waiting-rooms, dilapidated refreshment bars, and millions of rather faded commercial posters...
