The value of systems environmental tests is discussed in regard to flight safety, functional improvement and economic considerations. Environmental tests of mechanical, hydraulic, and pneumatic systems in the laboratory supplement the components tests and provide worthwhile design data prior to first flight. Typical examples of systems extreme temperature and altitude tests conducted at Lockheed Aircraft Corporation, California Division, are illustrated.

FATIGUE life of fighters, as discussed in this paper, is dependent on those variables which are a function of airplane mission characteristics and those which are a function of the operational environment. The first type of variable includes airplane design limit load factor, design range, combat and cruise altitude, and the basic kind of mission flown. The second class of variable includes gust loads, maneuver loads, landing-taxi loads, and the ground-air-ground cycle. This paper describes the fatigue damage caused by these factors in the flight histories of two hypothetical fighter aircraft.

THIS paper describes how present size and weight regulations are based on capacities of inadequate highways, or on various arbitrary bridge formulas, or sometimes both. Within a state, contradictory weight limits often are prescribed; and uniformity from state to state is noticeably lacking. Adapting the demand for bigger trucks and trailers for hauling more payload to the various size and weight limitations has resulted in some improvements in truck design. But what are needed are consistent regulations based on logic and fact to encourage designers to produce safer and more efficient vehicles - thus promoting the public interest. As the regulations stand now, Mr. Horine says, they do not benefit the public.

AERATION and cold-temperature starting problems faced by aircraft-engine designers are said to be solved by use of the deaerating cold-weather oil system described in this paper. In this system, all the oil in the tank circulates through the engine rather than the small volume of oil circulated by the conventional system.

THE scope of extensive research devoted to storage battery improvements during recent years is emphasized in this paper, together with a comprehensive review of results achieved to date. In an effort to produce an optimum battery, research has been directed to the qualitative factors, leading to improved performance during the life of the battery, and to quantitative characteristics which would lengthen its life. The author points out that manufacturers have concentrated on building more and more cranking capacity into their product, accomplishing this by decreasing plate thickness, increasing separator efficiency, and by the use of improved active material. He reviews the factors which limit life under cycling and overcharge conditions, and surveys the research which has led to the use of corrosion-resistant alloys to correct electrolysis.
