VARIOUS factors in cabin design are discussed by Mr. Prokosch in their relation to the governing considerations of types of service to be offered. Suggestions for overcoming some of the present discrepancies in design and furnishings are brought up, together with their relation to weight, cost, and ground time.

THE need for refrigeration in aircraft air conditioning has not been generally recognized in the past. Shown here are the reasons why refrigeration is a necessity. Three different methods of accomplishing it are also presented. The cooling requirements of the Lockheed Constellation are used as a basis for the study.

Summary A study is made in this paper of the fundamental requirements and methods associated with providing uncompromised air freshness, temperature conditioning, and humidity comfort for the passengers and crew of a typical large pressurized transport airplane, such as the Douglas DC-6, for flight under 30,000 feet. Investigation is made of the advisability of reclamation of cabin air through recirculation or by the use of counter-odorants. Special emphasis is given to the investigation and analysis of cabin air humidities. Air conditioning design recommendations for transport aircraft are made in the paper based on the charts and tables developed.

THE safety and dependability of scheduled air transportation depends, in part, on how practical is the cockpit in which the pilots spend their time and carry on their functions while in flight. The author of this paper, himself a pilot, has compiled here information gained from a questionnaire answered by representatives from every scheduled airline in the country. It appears that these pilots have definite ideas on the improvements that are needed in cockpits, discussed by the author under the following headings: 1. Cockpit window layout (including provisions for all-weather visibility). 2. Instrument panel arrangement. 3. Cockpit lighting. 4. Pilot comfort (including adequate seats, ventilation, and heating). 5. Type, location, and accessibility of controls.

INCREASING engine outputs have required methods to control the piston temperature. The work presented in this paper shows one successful means through the use of a piston of low conductive, correlated with an appropriate rate of piston cooling oil from the engine lubrication system. The effects of coolant temperature, load, and speed over the propeller load curve, and a piston baffle, on piston temperatures are investigated by thermocouples silver soldered in a 6 x 6½-in. diesel, two-cycle piston. Tests indicate that the rate of cooling oil does not have to be excessive to secure adequate cooling. Substantiating data from an 8 x 10-in. diesel engine are given. Steel piston designs for use with jet oil cooling are shown. These are for the 6-in. diesel on which most of the data for the paper were taken.

THIS paper presents a simple and rapid method of determining the performance of cross-flow intercoolers, oil coolers, or Prestone radiators from laboratory tests of a model or basic unit of the cooler. The method lends itself equally as well to the determination of the size of a cooler of any set performance. Due to the comparative rapidity with which these calculations can be made, it becomes, with the use of this method, an easy matter to make a series of calculations to determine the relations between lengths, cooling air flow, and pressure drops, for any desired performance.

MANY question whether a complete job of air-conditioning passenger cars for all weather conditions can be done at a price which most car buyers care to pay and with assurance that dependable and acceptable results can be guaranteed, Mr. Chase reports in prefacing this paper, a comparative study of existing heating, ventilating, and cooling systems. Some 1939 and many more 1940 car models, he believes, yield greatly improved results in heating the entire car and ventilating it well with all windows closed, but, he points out, the design of such systems is still in a state of flux.

THIS paper reports work begun in 1935 at the instigation of the Murray Corp. of America. Methods used in studying the relations between the automobile seat cushion and its function in transporting passengers with greater comfort and less fatigue are described. Constructed for this purpose was a piece of apparatus called the Universal Test Seat, whose dimensions were completely adjustable with arrangements to vary the distribution of the supporting pressure in any manner which seemed most comfortable to the passenger. The authors describe tests made by use of this apparatus, present summaries of some of the results recorded and conclude that, to give the passenger the maximum comfort and least fatigue, the following mechanical objectives should be attained by the cushion: 1. To support the passenger over a large area to get the smallest unit pressure on the flesh; 2.
