Book Description
Since the dramatic flight by "Chuck" Yeager in 1947, when an aircraft first exceeded the speed of sound, the dream of a successful supersonic airliner has captivated the interest of many manufacturers & of many governments. But as yet, only a few concordes & a couple of Tupolev Tu-144s have gone into service, on a very few routes & none were ever sold. The cost of developing any supersonic airliner is prohibitive. The prospect of their being able to operate economically is remote. The market for such an aircraft (which would have to charge premium fares, even more than first class) is very small. Manufacturers & government agencies alike continue to base their multi-million research programs on inflated market "estimates" that combine substantial elements of special pleading & wishful thinking. Statements invariably include a plethora of "shoulds" & "coulds" in their predictions; but their assumptions carry little weight, as they are ill-supported by known data. The conclusions drawn to produce market "estimates" of more than a thousand aircraft neither clear-headed nor objective. This book, written by an experienced analyst who spent most of his career in commercial airline market research & traffic forecasting, explodes the myth. The analysis draws upon known facts, applies simple arithmetic & makes assumptions that are based on technical, operational & commercial sense.

Book Description
Science is the great intellectual adventure, but can also be an instrument of profit, power, and privilege. Wrongly used, it might yet make the twenty-first century our last. To make sense of this, we need to let go of old ideas and assumptions. This No-Nonsense Guide to Science introduces a new way of thinking about science, moving away from ideas of perfect certainty and objectivity. We must accept uncertainty and ignorance in the field, as well as the need for citizens’ participation in the policies involving science.

Book Description
This book introduces a stability and control methodology named AeroMech, capable of sizing the primary control effectors of fixed wing subsonic to hypersonic designs of conventional and unconventional configuration layout. Control power demands are harmonized with static-, dynamic-, and maneuver stability requirements, while taking the six-degree-of-freedom trim state into account. The stability and control analysis solves the static- and dynamic equations of motion combined with non-linear vortex lattice aerodynamics for analysis. The true complexity of addressing subsonic to hypersonic vehicle stability and control during the conceptual design phase is hidden in the objective to develop a generic (vehicle configuration independent) methodology concept. The inclusion of geometrically asymmetric aircraft layouts, in addition to the reasonably well-known symmetric aircraft types, contributes significantly to the overall technical complexity and level of abstraction. The first three chapters describe the preparatory work invested along with the research strategy devised, thereby placing strong emphasis on systematic and thorough knowledge utilization. The engineering-scientific method itself is derived throughout the second half of the book. This book offers a unique aerospace vehicle configuration independent (generic) methodology and mathematical algorithm. The approach satisfies the initial technical quest: How to develop a ‘configuration stability & control’ methodology module for an advanced multi-disciplinary aerospace vehicle design synthesis environment that permits consistent aerospace vehicle design evaluations?

Book Description
In December 1943, a top secret contract (E.24/43) was awarded to Miles Aircraft. The contract was to build the world's first supersonic jet capable of 1000mph. The only reliable source of data on supersonic objects came from the Armament Research Dept and their wind tunnel tests on ammunition. From this, Miles developed an exceptionally thin-winged, bullet-shaped aircraft. the research was inexplicably passed to the Americans in 1944. By December 1945, one prototype was virtually complete. The second, destined for an attempt at the sound barrier was 80 per cent complete. In February 1946, Capt Eric Brown was confirmed as the test pilot and October 1946 was set for the supersonic trials. However, on 12 February 1946, Miles were ordered to stop production. No plausible explanation was given for the cancellation when Britain was within six months of breaking the sound barrier. Eric Brown and others directly involved including Dennis Bancroft, the Chief Aerodynamicist on the M.52, have now come together to try and finally solve the mystery behind the cancellation.

Book Description
Deep Stall applies a framework of strategic analysis to the Boeing Company. Boeing is the world's largest aerospace / defence company, with turnover in the region of US $60bn. The book examines the relative decline of Boeing in the civil aircraft market in relation to European manufacturer, Airbus. The aim of the book is to utilize the concept of strategic value to explain Boeing's decline. The authors define this concept as investment in people and technology to leverage future market success by developing innovative new products, arguing that Boeing has neglected strategic value in favour of shareholder value, defined in terms of short-term cash benefits. The rationale for the book exists both in the fact that the story in itself is interesting and also in the wider framework of analysis concerning the correct strategic approach for running a high technology business. The argument illustrates what can happen when quarterly returns become the predominant strategic rationale for a company. In the U.S. the business media (Economist, Forbes, Fortune, and Business Week etc) are now focusing on the question of Boeing's decline and the major implications for the U.S. national interest. Boeing is one of the jewels in the US technology crown, but today U.S. jobs and capability are being exported abroad, with most of its aircraft program work based in Asia. This is a hot topic in the US which explains why the business media are now so interested in this question. The book sits squarely in the centre of this debate. Deep Stall concludes with a brief analysis of the recent fight-back that has been evident in Boeing's fortunes and the successful campaign to sell the new 787. The authors probe the question of whether Airbus or Boeing is likely to dominate in the next ten or fifteen years.

Book Description
The updated and expanded third edition of this book focuses on the multi-disciplinary coupling between flight-vehicle hardware alternatives and enabling propulsion systems. It discusses how to match near-term and far-term aerospace vehicles to missions and provides a comprehensive overview of the subject, directly contributing to the next-generation space infrastructure, from space tourism to space exploration. This holistic treatment defines a mission portfolio addressing near-term to long-term space transportation needs covering sub-orbital, orbital and escape flight profiles. In this context, a vehicle configuration classification is introduced covering alternatives starting from the dawn of space access. A best-practice parametric sizing approach is introduced to correctly design the flight vehicle for the mission. This technique balances required mission with the available vehicle solution space and is an essential capability sought after by technology forecasters and strategic planners alike.
