Estimating the charge size in explosive forming of sheet metal
(College of Aeronautics, 1964-05) Noble, C. F.
A method is given for estimating the charge size for the explosive forming of sheet metal components. The method is applied to a number of relatively simple shapes and good agreement is shown with experimental results.

Horizontal band-saw
(College of Aeronautics, 1964-05) Foot, R. M.; Boardman, G. E. T.; Dailey, B. R.; Baller, E. G. A.; Noble, C. F.
The effect of various parameters on the performance of the band saw when cutting mild steel-with a 10 t.p.i. raker-set blade were established over a limited range. These are discussed fully in the ‘conclusions'. With this limited survey it was not found possible to establish the optimum conditions of operation.

Note: estimating the charge size in explosive forming of sheet metal
(College of Aeronautics, 1964-03) Noble, C. F.; Oxley, P. L. B.
Note: Estimating the charge size in explosive forming of sheet metal In the explosive forming of sheet metal some relatively easy method of estimating the size of the charge is needed. This short note describes a method in which the size of the charge is found by equating the work done in forming the component to that part of the explosive energy available for doing work on the component … [cont].
