"In the development of high temperature materials of the brittle category, the need to improve their impact strength for some applications has brought with it a demand for a simple machine for measuring impact resistance, both at room and elevated temperatures, and preferably one in which corrections such as the toss energy are negligible. This report describes such a machine and presents the results of some preliminary tests on the effect of temperature on impact strength of several alloys and cermets. A comparison is also given between the impact resistance of notched and unnotched specimens" (p. 1).

Report presenting information on the engine performance variations resulting from bleeding air from the compressor for turbine cooling, which is currently lacking. A thermodynamic-cycle investigation was conducted to determine the magnitude of the performance variations for a wide range of operating conditions for turboprop engines and for both afterburning and nonafterburning turbojet engines.

Report presenting an exploration of fuel temperatures, which includes variables such as the aircraft speed, flight time, flight altitude, materials of construction, location of fuel tanks relative to aircraft skin and hot engine parts, and other factors. The results illustrate that it is impossible to predict quantitatively the fuel temperatures that will be attained in aircraft without detailed design information on each machine.

The purpose of this report is to present a HAPO proposal for the design and construction of a high-temperature, high-pressure light water recirculation test facility for the Westinghouse Electric Corporation, Atomic Power Division This report does not attempt to justify the feasibility of site location nor does it attempt to elaborate on such technical considerations as permissible test specimen heat generation and enrichment requirements which have been covered in an earlier document. Instead, detail information is developed on the proposed design with major emphasis on detail descriptions of the proposed loop and auxiliaries, design and construction scheduling and costs, and operating costs.
