The welding designer requires a philosophy for his design responsibilities
and a thorough understanding of the basic principles in the subjects covering
his responsibilities. The education of the welding designer must ...
The feasibility of constructing a device to give a measure
of pilot reliability has been investigated. A rig to meet the proposals
made by BLEU has been designed and basic circuits constructed and tested
for accuracy ...
Summary
The work reported in this memo is the initial stages of an investigation
of the time-dependent behaviour of certain anisotropic polymers. In the
first instance low density polyethylene with a transversely ...
An intensive investigation into the grinding process was carried
out in The College of Aeronautics Machine Tools Laboratory during 1955-6.
The outcome of this work was a method of evaluating the efficiency of
grinding ...
Since the last report to sponsors circulated in mid-1967, considerable
concern has been felt over the wide scatter of results. The scatter in results
between specimens produced in a single batch was generally ...
The College of Aeronautics Transport Short Course, Transport Short Course(College of Aeronautics, 1968)
An integral part of the two week transport short course was a group
project study by course members, applying material presented on the
course to a practical problem in transport systems analysis. Airport
location in ...

Introduction
1.1.1 This is a project report written by the members of the
College of Aeronautics short course held between 24th February and
7th March, 1969.
1.1.2 An Interim Report was presented by the Planning ...

Introduction
This memorandum reports a series of tests to determine the fatigue
properties of an iridium - 5% tungsten alloy at 600°c and 700°C.
A previous memorandum, Memo. Mat. 61, reports the fatigue properties
at ...

The thermal degradation of a bisphenol-A based epoxy resin (EP 274)
cured with 4,4’ -diaminodiphenyl methane (DDM) and with phthalic anhydride
(PA) was studied using pyrolysis gas chromatography. Conclusive evidence
for ...
A test programme was to be carried out to evaluate a series of
additives for use in industrial metal cutting coolants for use initially
on the turning, drilling and milling processes. These tests when they
take the form ...
The original terms of reference under which the project was undertaken
are included in this report and the requirements requested are satisfied.
On initial contact at Aliens, I was introduced to Mr. Colson, who
informed ...
The object of the visits was to discuss the current state-of-the-art
with the Engineering Departments of several North American airlines which were
known to be leading the field in the application of certain advanced ...
1. Introduction
A basic problem in the design theory of semiconductor systems
such as p-n junction devices relates to the determination of the spatial
variation of electrostatic potential, 4, of electric field intensity,
and ...
The equation for the pressure fluctuations in a turbulent boundary
layer are derived with special reference to their values at a rigid wall.
It is shown that in incompressible flow the pressure field is defined
completely ...

In our first report on containers published in January,1967,
we tried to summarise progress in this new mode of
transportation and to define some of the problems which
existed.

A thin-film resistance thermometer, mounted on
the end-wall of a shock tube, is used to record
surface temperatures and heat transfer rates following
reflection of the primary shock wave.
This information is combined ...
This note gives a survey of codes particularly useful for computational
and analogue to digital circuits. Also included are logic circuits capable
of converting the code into natural binary form as at some stage in a ...
Short Eros. and Harland Ltd. have carried out a brief
preliminary study of the Turbo-Skyvan for crop-spraying and
have derived payload data and operating costs on a provisional
basis.
Further studies have been carried ...
