A 1200-Ton Goliath Shipyard Crane

In today's modern shipyard, an important tool is a crane of heavy lift capacity. A 1200-ton gantry crane, with a span of 119 m (390 ft) between the rails, was recently put into service at the Quincy Shipbuilding Division of General Dynamics Corporation in Quincy, Massachusetts. The paper describes some design aspects of the crane and the assembly and erection of this massive engineering structure.

The Canadair CL-84 Tilt-Wing V/STOL Programme

In 1956 the Defence Research Board of Canada and Canadair Limited (a wholly-owned subsidiary of General Dynamics Corporation), agreed to sponsor jointly a study of V/STOL technology to determine the configuration of aircraft best suited to the support of ground forces. During the following year it was decided that for the transport role the tilt-wing/slipstream-deflection concept promises the best aircraft from the overall point of view. Subsequent analysis and flight experience have confirmed this, and have also demonstrated a high degree of compatibility between aircraft attributes and general requirements for support of surface forces.

Flight Characteristics of the B58 Mach 2 Bomber

The B58 was developed and produced for the United States Air Force by the General Dynamics Corporation, Fort Worth Division, Texas. Until recently the organisation was known as CONVAIR, Fort Worth Division.The B58 provided an abrupt advance in the technology of military aviation. In one step the speed performance of the strategic bomber was more than doubled over that of its predecessors.The development and manufacture of the B58 was accomplished under the Weapons System Management Concept. Development of the aircraft began in 1951 with the origination of design studies. Detail design and manufacturing efforts were started in 1954. Initial flight of the prototype occurred in November of 1956. An exhaustive flight test evaluation programme then ensued in parallel with production of the aircraft. The flight test programme utilised a substantial fleet of B58's, and the combined efforts of the manufacturer and the U.S.A.F.
