Some notes on the factors influencing the possible damage to buildings due to the passage of shock waves from aircraft flying at supersonic speeds

Lilley, G. M. (College of Aeronautics, 1952)

The purpose of this note is to discuss, from the limited information available, the order of magnitude of the strength and the configuration of the shock waves, close to ground level, generated from aircraft flying et ...

A note on the application of the vortex tube to ventilated suits

Westley, R. (College of Aeronautics, 1953-04)

The vortex tube has no moving parts and its makes it an attractive form of refrigerator when a source of compressed air is available. The drawback is that this device has a low efficiency. The proposed application ...

Conversion of Douglas Dakota G-AMZE for Smith autopilot type D development

Firth, A. (College of Aeronautics, 1953-11)

Dakota K.J. 874 was delivered as a standard R.A.F Mark IV paratrooping aircraft. The undermentioned modifications were called for in order, to convert it to an aircraft suitable for the carrying out of flight tests & ...

A resume of maximum lift data for symmetrical wings, with various high-lift aids

Nonweiler, T. (College of Aeronautics, 1954-03)

We shall attempt here to summarise the existing data on the values of the low-speed CLmax of wings, in the absence of a fuselage, and without including information on stalling incidence or pitching moment. The summary ...

A bibliography and survey of the vortex tube

Westley, R. (College of Aeronautics, 1954-03)

A comprehensive bibliography of vortex tube publications is given together with a brief survey of the development of the vortex tube between 1931 and 1953.

The calculation of the wave drag of a family of low-drag axisymmetric nose shapes of fineness ratio 4.5 at zero incidence at supersonic speeds

Marson, G. B. (College of Aeronautics, 1954-05)

The pressure drag coefficients of a particular family of convex logarithmic projectile nose shapes in which the nose angle is an important parameter have been calculated over a range of supersonic Mach numbers using a ...

Proceedings of the work study school conference. Cranfield, March 1954

College of Aeronautics, (Cranfield) (College of Aeronautics, 1954-06)

The Conference was arranged by request of the students of the Work Study School who attended the three courses. Out of a potential 56 students, 34 attended the Conference, and apologies for their absence were received ...

Factors affecting punching speeds of hollerith operators. Mechanical factors outside the control of the operators

Majewski, T. R. (College of Aeronautics, 1954-06)

One of the major influences governing punching speeds is the operator's reaction to what she regards as the innate stiffness of the punch. This Note reviews those factors which are attributable to the machine rather ...

Longitudinal stability characteristics and damping in pitch of delta wings

McCarter, W. B. (College of Aeronautics, 1954-07)

The usual technique of longitudinal stability analysis is adopted but particular attention is paid to those elements that contribute to damping, The cases of two delta plan form. aircraft of 45° and 60° sweep angle are ...

Some bearing materials under high pressures at low rotational speeds

Preston, C. (College of Aeronautics, 1954-07)

A series of tests were carried out, in the Design Department of the College of Aeronautics, on plain journal bearings, at higher pressures than are normally encountered in engineering practice. Pressures of 40,000 lb/in.2 ...

The wave drag of highly-swept wings: a comparison of linear theory and slender body theory

Nonweiler, T. (College of Aeronautics, 1954-10)

This note comments on the comparison between the answer obtained by linear theory for the wave drag of slender-wings (as interpreted by the limit and that value for the drag obtained by Slender-Body Theory. It is shown ...

Machinability investigations into special materials. Part 1 stainless steel Rex 448 hardened and tempered to Brinell minimum 321, maximum 375

Purcell, J. (College of Aeronautics, 1954-11)

This Report deals with the machinability of Firth-Vickers materials. Reference REX WO (Stainless Steel) in the hardened and tempered condition* U,T.S 70-75 tons; Brinell hardness 321 minimum, 375 maximum. CONTENTS: SECTION ...

Solution of a load diffusion problem by relaxation methods

Vaisey, Gillian; Hemp, W. S. (College of Aeronautics, 1954-11)

SUMMARY The need. to generalise the usual assumptions made in the analysis of load diffusion problems has been emphasised by recent experimental work (Ref. 3)1 which has shown the importance of bending of the edge ...

Rational presentation of histogram data on samples

Williams, J. A. C. (College of Aeronautics, 1955-01)

SUMMARY Misconceptions can be caused by the common method of presenting sample data by histograms. A rational method of treating and presenting histogram data is outlined which attempts to overcome misconceptions caused ...

Flight tests on a torquemeter installed on Gipsy Queen 71 engine on dove aircraft

Robertson, I. A. (College of Aeronautics, 1955-02)

The torquemeter failed at 178 hrs. 50 minutes flying. Torquemeter powers compared with engine powers deduced from maker's curves give the following results: 1) At low BHP readings the torquemeter tends to over-read 2) ...

Avoidable delays among women workers on light work

Williams, J. A. C. (College of Aeronautics, 1955-02)

SUMMARY Time Study makes use of certain allowances in correcting observed times to standard times. One allowance, the 'fatigue' allowance of F.W. Taylor, allocates a certain period of the working day to rest on a basis ...

The lift induced on a circular cylinder by a narrow jet emerging at an angle to the uniform stream

Anderson, R. G. (College of Aeronautics, 1955-02)

SUMMARY A preliminary qualitative study has been made in a smoke tunnel of the flow around a stationary circular cylinder, having rear jet blowing, placed in a uniform stream. Motographs have been taken which show many ...
