Solar hot water systems application to the solar building test facility and the Tech House

Projects which relate to the current national thrust toward demonstrating applied solar energy are discussed. The first project has as its primary objective the application of a system comprised of a flat plate collector field, an absorption air conditioning system, and a hot water heating system to satisfy most of the annual cooling and heating requirements of a large commercial office building. The other project addresses the application of solar collector technology to the heating and hot water requirements of a domestic residence. In this case, however, the solar system represents only one of several important technology items, the primary objective for the project being the application of space technology to the American home.

The NASA Space Processing Program

The program is intended to initiate utilization of spaceflight for economically beneficial activities in all branches of materials science and technology. In view of the prospect they offer for reducing the costs of space operations, the Spacelab and Space Shuttle are expected to become widely used for work on materials early in the 1980's. At first they will be employed for space experiments and for services, such as sample preparation, that support research and development activities on the ground. Orbital manufacturing operations are expected to develop as well when research has prepared an adequate basis for them. During the past year, NASA has initiated a series of rocket flights on which prospective participants in the Shuttle/Spacelab program can perform preliminary experiments. Participation in these flights is open to investigators from all countries, and experiments are being solicited from private sponsors also. NASA is performing concurrent definition studies of Shuttle/Spacelab payloads, and design work on equipment for the first two years of operations is planned to begin early in 1977. The Office of Applications currently plans to fly two space processing payloads on Orbital Flight Test missions in 1980 and two on operational Spacelab missions in 1981.

A systematic approach to advanced cockpit warning systems for air transport operations: Line pilot preferences

Line pilots (fifty captains, first officers, and flight engineers) from 8 different airlines were administered a structured questionnaire relating to future warning system design and solutions to current warning system problems. This was followed by a semantic differential to obtain a factor analysis of 18 different cockpit warning signals on scales such as informative/distracting, annoying/soothing. Half the pilots received a demonstration of the experimental text and voice synthesizer warning systems before answering the questionnaire and the semantic differential. A control group answered the questionnaire and the semantic differential first, thus providing a check for the stability of pilot preferences with and without actual exposure to experimental systems. Generally, the preference data obtained revealed much consistency and strong agreement among line pilots concerning advance cockpit warning system design.

Factors Affecting the Corporate Decision-Making Process of Air Transport Manufacturers

Fuel economy is a pivotal question influencing the future sale and utilization of commercial aircraft. The NASA Aircraft Energy Efficiency (ACEE) Program Office has a program intended to accelerate the readiness of advanced technologies for energy efficient aircraft. Because the decision to develop a new airframe or engine is a major financial hazard for manufacturers, it is important to know what factors influence the decision making process. A method is described for identifying and ranking individuals and organizations involved at each stage of commercial air transport development, and the barriers that must be overcome in adopting new technologies.
