MANY months of discussion about ways of making good the scarcity of technologists in all the engineering industries, and in the aircraft industry more than most, have culminated in the publication of the white paper on Technical Education. In this the Government announces its plans for greatly...
The paper is mainly concerned with how the gasturbine designer can choose the best design of liquid or gaseous fuel combustion chamber for his purpose. In the method proposed, combustion chamber test data are expressed in a way which gives the most general information about the design, by...
This paper describes the use of preset and programme parameters with the matrix interpretive scheme which was considered in Part I for the preparation of general purpose programmes for an electronic digital computer. The implications of partitioning the matrices when using the force method of...
For a delta wing it is not sufficient to consider spanwise bending and chordwise rotation only. Chordwise bending must be added. It is therefore necessary to calculate the aerodynamic coefficients accordingly. The theory of Lawrence and Gerber dealing with aerodynamic coefficients of oscillating...
HELICOPTER performance methods currently in use fall into two main groups. The smallest is typified by Refs. and, and evaluates performance by considering the forces acting on each element of the blade. To do this it is first necessary to determine the flapping and pitch angles of the rotor, and...
SEVENTEEN papers were presented during the three days of the conference on a variety of topics affecting fatigue in aircraft structures. The conference was organized under the joint auspices of the Department of Civil Engineering and Engineering Mechanics, Columbia University, and the Air...
The cardinal purpose of mathematical analysis is to establish the validity of the concepts, theorems and artifices which comprise the mathematical machine, and to prescribe the limitations and reservations to which the operations by this machine are subject.
Under this heading are published regularly abstracts of all Reports and Memoranda of the Aeronautical Research Council, Reports and Technical Memoranda of the United States National Advisory Committee for Aeronautics and publications of other similar Research Bodies as issued.
The development of high performance gas turbine engines for future generations of civil airliners and military aircraft is becoming increasingly diflicult because of the severe limitations of flight testing. In order to overcome some of these difficulties RollsRoyce have begun to build a...
The inner wall 10 of a gasturbine diffuser is formed with two rows of circumferential slots 40, 42 whereby, due to the increasing static pressure in the downstream direction, gas will flow into the downstream slots 42 and out of the upstream slots 40 to set up a circulation which will energize...
