An Evolutionary Approach to the Design of Flight Decks for Future Civil Transport Aircraft

This paper discusses a programme of work being carried out jointly by the British Aircraft Corporation and Hawker Siddeley Aviation, into the design of flight decks for future civil transport aircraft. The programme is aimed at exploring all aspects of flight deck design, in sufficient depth to enable decisions to be made as to whether or not significant changes could, or should be introduced into aircraft scheduled to enter service in the 1980s. Some of the information now presented has been published previously by my colleagues engaged on the programme. I make no apology for this, since any story worth telling is also worth repeating — and perhaps embellishing in the process.

Flight Decks for Future Civil Transport Aircraft

This paper, by the Assistant Chief Electro-dynamic Engineer of the British Aircraft Corporation, was originally presented at the Annual General Technical Meeting of the Guild of Air Pilots and Navigators in September 1976.This paper discusses a programme being carried out jointly by the British Aircraft Corporation and Hawker Siddeley Aviation into the design of flight decks for civil transport aircraft scheduled to enter service in the 1980s. The flight decks of today have evolved as a result of experience gained since manned flight began; it would be foolhardy to ignore this background and in applying new technology care must be exercised in preserving, as far as possible, conventions and practices which have long been established.

A wing for the Airbus

The principal aim of the wing designer is to increase the maximum loading per unit area of wing. The European Airbus, the third generation of civil jet aircraft, presented particular problems in aerodynamic design. This article describes the development programme at Hawker Siddeley Aviation which led to the 1976 Queen's Award for technological achievement.

The Changing Balance of Design Requirements

The two goals of maximum reliability and minimum maintenance costs occupy the energies of today's designers to an ever increasing extent. This was made clear in the contributions to a symposium on the ever changing balance of design requirements which dealt with reactions from various sources. From the manufacturers of aircraft which may have a ‘lead‐time’ of up to 6 years from original market research, a considerable amount of predictions must be made regarding future technological and economic trends as well as market potential. Hawker Siddeley Aviation's speaker referred to the increasing complexity of aircraft and air traffic control equipment and therefore, the increased costs to be balanced by increased productivity. It is the HSA Group's policy to treat aircraft maintenance cost as a major design parameter, targetting and control being undertaken by the design department in a similar fashion to weight and performance control.

Weapon Aiming System

IN the design of the Hawk/Ground Attack/Trainer aircraft, Hawker Siddeley Aviation had two targets in view (a) to produce a versatile, tough aircraft to a fixed price and (b) to produce an aircraft having a very high degree of reliability as a complete weapon system.

The aerodynamic development of the wing of the A 300B

The A300B, otherwise known as the European Airbus, is an international collaborative project. Hawker Siddeley Aviation are under contract to Airbus Industrie to design and manufacture the wing. Manufacture is now well advanced, the first wing having been delivered to Toulouse in November 1971.In describing the aerodynamic development of the wing for this aircraft, it is necessary to describe events before the advent of the designation A300B, as the aerodynamic design philosophy was established prior to that date. In particular reference will be made to the preceding paper project the A300 and to a lesser extent to projects being considered before the opening of technical discussions between Sud Aviation, Deutsche Airbus, and Hawker Siddeley Aviation.

Safety hardware discussed at the BALPA conference

OF THE SEVERAL PAPERS read at the symposium of the British Airline Pilots Association on safety, three speakers predominantly concerned themselves with safety through hardware rather than flight routine and the human factor. Mr. S. C. Caliendi of Hawker Siddeley Aviation was concerned with the part the designer can play in safety and particularly in ensuring adequate feedback of information and experience gained from aircraft in service. Mr. L. J. W. Hall of the Airworthiness Division of the Civil Aviation Authority, speaking on “Safety Margins and Aircraft Performance” gave a certain amount of thought to the development or improvement of equipment for enabling the pilot to make decisions. Finally Mr. Milton Lalas of Qantas Airways Ltd actually listed specific equipment and suggested how it could be improved.

V/Stol developments in Hawker Siddeley Aviation Limited

At the beginning of manned flight, aircraft needed some length of ground run in order to take off and fly. The Wrights took under 60 ft, and with a wing loading of 1.47 lb/sq ft and a CL max of approximately 0.9 they achieved first manned flight.Time went on, and man grew more familiar with the hazards of increased take-off length and take-off speed. His growing knowledge of aerodynamics allowed him to increase the CL max values on wings. These facts combined to allow him to use increased wing loadings to improve his flight efficiency in terms of payload, cruise speed and range. The following graphs show the growth of these characteristics.

Weighing machines

Equipment capable of weighing a whole range of aircraft including future projects, was required by Hawker Siddeley Aviation. Furthermore it had to be flexible with the nose wheel weighing unit mounted on a lift and with the minimum possible disturbance to the existing hangar floor.

A Carbon Fibre Vulcan Airbrake Flap

After an initial evaluation of the carbon fibres and matrix resins available at the time (1968) Hawker Siddeley Aviation embarked, under the sponsorship of the then Ministry of Technology, on the design and development of a number of representative aircraft structural components in order to gain experience of the overall problems involved and to give a lead in determining the direction of the necessary materials and process development programmes. An essential feature of this work was that the components produced should be cleared for extended flight trials so that not only would a good deal of useful service experience be gained but also many principles of quality and process control would be established and a platform for discussions with the various official bodies would be provided. In addition, by using the normal shop facilities for the manufacture of the components, it was hoped to introduce as many company personnel as possible to the new material.

Aerodynamic features

THE conventional appearance of the A300B belies its aerodynamic refinement. Early research work initiated by Hawker Siddeley Aviation has been extended by wind tunnel testing in France, the United Kingdom, Germany and Holland.

The Advance Towards Category Three Automatic Landings

AT the present time the B.E.A. Trident fleet is cleared to perform Automatic Landings at suitable airfields throughout the U.K. and Europe in weather conditions down to Category 2 defined limitations. This means that the captain must have visual contact with the runway from a height of at least 100 ft. in order to be fully able to monitor the final stages of the automatic landing. This clearance stage has been achieved by satisfactory demonstration to the Air Registration Board of the performance and safety standard of the Smith's Autoland system by a large number of landings made on test Tridents operated by Hawker Siddeley Aviation Ltd.

Tooling for the Buccaneer

THIS year the Hawker Siddeley Buccaneer low level strike and reconnaissance aircraft goes into service with the Royal Air Force. Already well established with the Royal Navy and built to fly at high subsonic speed at low level, its manufacture posed unusual problems. The central load‐bearing framework is literally carved out of blocks of steel. This demanded special machinery and none was immediately available on the market. Hawker Siddeley Aviation, Brough, met the problem by designing its own.
