MOST British people who go to what is commonly called the Paris Aero Show think of it first as an opportunity to assess the work of the French aircraft industry, and indeed in the past the function was dominated by the industry of the organizing country. The trend in recent years, however, has...
THE use of liquid oxygen as an oxidizer for various fuels in liquid rocket propellent systems is not new. Professor Goddard used liquid oxygen in his rocket experiments and the well known German V2 rockets used this material as an oxidizer. However, its effect on nonmetallic materials ordinarily...
Continuing Chapter V, internal stress resultants are established for the open rings in he fuselage due to the various statically equivalent and selfequilibrating load systems. The determination of the frame redundancies leads immediately to the corresponding results for the closed rings. The...
Based on the induction link principle for the production of an electrical signal having a linear relationship with movement, the Schaevitz linear differential transformer provides a versatile tool in the hands of transducer designers.
Ceramic magnetic materials, known as ferrites, have been developed by Boeing. The magnetic field can be induced at the same time as the material is formed under heat and pressure. The resulting magnets have two to three times the magnetic strength of iron, on a weight basis.
The first number of the sixteenth volume in this series contains eighteen papers covering the usual wide range of topics. The longest paper describes a photoelastic investigation carried out in the U.S. Naval Research Laboratory, Washington, D.C., to determine the dynamic stress distribution...
In a jetpropelled aircraft, takeoff and landing is facilitated by arranging laterally disposed jetpropulsion units 7, 7a for pivotal movement about transverse axes and by the provision of adjustable deflectors 48, 48a, 49, 49a in the jet nozzle of an engine not shown mounted in the fuselage. A...
A gas turbine engine compressor blade, the blade being formed of synthetic, resinimpregnated, cloth laminations bonded together and having an outwardly divergent root portion extending chordwise of the blade, said root portion having the outer divergent faces thereof forming angles of...
A. A. Jones & Shipman Ltd., Leicester, have introduced a high precision cylindrical grinding machine for small batch work. Feed increments are in steps of 0.000005 in. diameter reduction 0.000010 in. and roundness accuracy is quoted as 0.000010 in. on dead centres 0.000025 in. on live standard...
Early aircraft engines were usually bolted direct to the aircraft structure and no attempt was made to prevent the vibrations which they set up from being transmitted to the airframe. With increasing engine powers and the use of larger airscrews these vibrations eventually become of sufficient...
