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.

IN Aircraft Engineering for October 1956 (p. 362) Lockwood Taylor discussed the wind‐tunnel interference arising from model supports and their guards, and gave a theoretical analysis for the contribution due to the flow curvature induced at the model and that due to the increment in longitudinal velocity (solid blockage). Both these are potential‐flow effects.

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.

British Aircraft Corporation recently announced the new Board of English Electric Aviation Ltd. and the composition of the Board of Directors of the new company British Aircraft Corporation (Guided Weapons) Ltd. This follows the announcement that English Electric Aviation is taking over from English Electric Ltd. its aircraft manufacturing facilities at Preston and Salmesbury and that the guided weapons interests of English Electric Aviation and of Bristol Aircraft Ltd. are being integrated under the management of a new company, B.A.C. (Guided Weapons) Ltd.

The surface of a very high speed aircraft is cooled by a liquid, e.g. a fuel, which flows rearwardly there‐over and enters the intake of one or more gas turbine or ram jet engines where it is burnt to provide thrust. In the aircraft illustrated, the leading edges of the delta wing 1 arc formed by a strip 3 of liquid‐pervious material, e.g. perforated or slotted sheet or sintered metal sheet, the strip forming part of the wall of a duct 4 supplied with fuel through a pipe 6, as illustrated. Further liquid‐pervious strips 7, 8 may be provided above and below the wing to emit additional fuel. As the fuel flows rearwardly it is evaporated in the boundary layer and enters the intakes of gas turbine engines 13 disposed along the wing trailing edges. The intakes extend above and below the wing to an extent greater than the thickness of the boundary layer so that practically all the fuel emitted on the surface is utilized in the engines. The fuselage 2 may be similarly cooled by liquid‐pervious sections 14, 15. In an aircraft with swept‐back or swept‐forward wings, the engines are situated at the wing tips or wing roots where the boundary layer tends to converge so that the fuel emitted on the wing surface enters the engine intakes. A further engine may be mounted on the end of the fuselage to receive the liquid emitted thereon. Thermocouples in the surface of the wing may control the liquid emission. It is stated that fuel evaporating in the aircraft boundary layer, will, by its cooling effect, promote laminar flow.

At a recent meeting of the Glasgow Grocers' and Provision Merchants' Association, it was alleged that there are provision merchants in Glasgow who are doing a large business in selling margarine as butter at 1s. 2d. per pound. In commenting upon this statement The Grocer very properly urges that the officials of the Association referred to should take prompt steps to place the facts in their possession before the Glasgow authorities and their officers, and observes that in certain cities and towns—Birmingham, for example—the grocers' associations have co‐operated with the authorities in their efforts to suppress illegal trading, particularly in regard to the sale of margarine as butter. It appears that one of the members of the Glasgow Association expressed the opinion that the Margarine Act has been a failure and that shopkeepers who sell margarine as butter should be charged with obtaining money under false pretences.

The world of management and technology has become accustomed to the notion of “2.0” advancements and transformative innovations. Is the field of Change Management/Organizational Development itself in this story? Not enough! We re-examine the field’s foundational beliefs, practices, focus, research directions, and value add. We conclude that there is strong evidence from the front line and from an IBM Case Study that the field must “reboot” – to rethink our methods and frameworks; the role and skills of change leadership for the future; change practitioner capabilities for the future; the metrics needed to evaluate progress; and the knowledge exchange between Academe and practitioners.

Organizational Development and Change (ODC) has been called to aid organizational greening goals. Carbon labeling of products by organizations is a common greening strategy. However, its effectiveness is dependent on supportive consumer behavior. The Theory of Planned Behavior (TPB) is used to explain actor choice in buying low carbon products (LCPs). Actual buying behavior of 873 subjects in China, a country new to carbon labeling, demonstrated that Declarative norms, Attitude, and Perceived behavioral control explained significant variance in actual buying behavior of LCPs. The TPB model may be better served by observing actual behavior versus behavioral intention. Revisions to the TPB model for diagnosis and interventions in behavioral change are indicated. ODC should revert to theoretically informed practice versus the increasing reliance on A-theoretical tools and techniques.
