Abstract

A study of the main parameters to be resolved for civil V/S.T.O.L. aircraft, the necessity for all weather operation, the airport requirements and the competition from other forms of transport. FROM a choice of a wide range of V/S.T.O.L. applications, this paper is concerned with the civil aircraft aspects. It deals with the main parameters to be studied in resolving V.T.O.L. and S.T.O.L. aircraft characteristics, the weighting of these toward favourable performance and to meeting the proposed certification rules for this form of transport. The part to be played by electronics in all weather operations is also discussed. Competition from surface transport, and V/S.T.O.L. airport requirements are referred to, and some general characteristics of the many different aircraft configurations are discussed. Some conclusions are reached suggesting the direction and weighting of future work.

Abstract

IN a previous article (Ref. 1, 1966), Chichester‐Miles of H.S.A. discussed some of the advantages and opportunities offered by the use of V.T.O.L. aircraft in short haul air transport. In a more recent article (Ref. 2, 1969), Boorer and Davey of B.A.C. reviewed the characteristics and some of the operational problems of V/S.T.O.L. aircraft, and argued in favour of initial civil S.T.O.L. aircraft leading to V.T.O.L. developments as an effective part of the overall ground and air transport system of the 1970s, on the basis of a foreseeable market demand for such aircraft at ranges between 50 and 300 miles. Quoting from their conclusions: ‘S.T.O.L. commercial operations appear therefore to be just around the corner. V.T.O.L. commercial operations may be a decade or so away but, as and when a S.T.O.L. inter‐city transport system develops, the improvement of S.T.O.L. performance toward V.T.O.L. may well become attractive and perhaps even necessary.’

Abstract

This paper discusses a large range of layouts that have been studied in relation to both strike and transport V/S.T.O.L. requirements. The performance of aircraft with different powerplant arrangements is considered, with the effects on structure and aerodynamics being based on extensive detail design work.

Abstract

A joint connects the centre section of a tapered thickness wing or wing portion 1 to the corresponding section of another wing of tapered thickness 2 or to a wing portion of constant thickness, in which the spar‐booms 3 and stringers 4 terminate between and are bolted to pairs of attachment plates 10, 11 matching the cross‐sectional shape of the wing and bent beyond the ends of the spar‐booms 3 and stringers 4 to form portions of uniform spacing which are bolted with the inter‐positioning of a spacer 13 between each pair of plates 10, 11 to flanges 7, 8 on one side of a vertical beam 6 matching the cross‐sectional shape of the wing and situated in a portion of constant thickness between two wings or at the end of the constant thickness portion of the wing. As shown, the wing sections each comprise spar‐booms 3, stringers 4 and skin plating 5. At the junction of the wings 1, 2 is a vertical beam 6 with stiffening ribs 9, at the lop and bottom of which are parallel flanges 7, 8. The ends of the spar‐booms 3 and stringers 4 are disposed between and secured to, by a row of bolts 12, two plares 10, 11, which are so bent that the portions extending beyond the ends of the members 3 and 4 are in the planes of the flanges 7, 8. Together with an intermediate spacer 13 and junction plate 16, the overlapping parts of the plates 10, 11 are secured by bolts 14, 15 to the flanges 7, 8. The junction plates 16 have separate end sections 20, which are secured by ‘U’‐bolts 21 to the members 18, themselves secured to the spar‐booms 3 by bolts 19.

Abstract

THE Report of the Committee on Libraries, which was issued by the University Grants Committee in the summer of 1967, had for long been called the Parry Report after its Chairman, Dr. Thomas Parry, formerly Librarian of the National Library of Wales and at the time the Principal of University College of Wales in Aberystwyth. When it was first set up in June 1963 the terms of reference were as follows:

Abstract

The first series of colours experimented upon was the high‐grade Kohnstamm colours, which have been physiologically tested and prepared especially for use in colouring food products. The results recorded below are not the results of a single determination, but the experiments were repeated until we were satisfied, working with the chemicals we used, and by the methods employed, that the results were uniform and reliable. The results with the Kohnstamm dyes are as follows : —

Abstract

ALTHOUGH the first Public Libraries (Scotland) Act was placed on the Statute Book in 1853, it was not until 1899 that the Corporation of the City of Glasgow was empowered to establish and maintain public libraries throughout the city. Between 1876 and 1897 four attempts were made to secure public approval for the adoption of the Public Libraries (Scotland) Acts, but when all these efforts proved unsuccessful, the Corporation decided in June, 1888 to include in a Local Bill for submission to Parliament, certain clauses conferring upon themselves the power to become a library authority. Promoted in 1899, the Bill became known as the Glasgow Corporation (Tramways, Libraries, etc.) Act 1899, and the library clauses passed through Parliament without opposition and received Royal Assent on 1st August, 1899. The powers conferred by this Local Act empowered the Corporation:

Abstract

Privatisation of services from the public sector is topical currently mainly because of the potential savings and efficiency to be gained. In the aspect of property management, the Hong Kong Housing Authority owns more than 600,000 units of public housing flats and the requirement for good and efficient property management services is enormous. The current policy of privatising these services to the private management agents has proved to be a correct direction in terms of retaining the growth of the public sector, and also improving the level of services to the tenants. While the privatisation scheme might bring in more opportunities for growth of the property management companies in the private sector, it is more important for the government to forge a proper transitional arrangement to switch to full private management in order not to endanger the already low morale in the public sector.
