The Determination Of Avionics Redundancy For Minimum Cost, Myron Kayton, William A. Klein

Space Congress® Proceedings

This paper describes an analysis of the level of redundancy of line repaceable units (LRUs) required for the Space Shuttle avionics system. The required number of LRUs is neither based on an arbitrary numerical probability nor on an aribtrary number of replicative units. Instead, a total cost to the program of each added LRU is calculated and the configuration that results in lowest program cost is selected.

The analysis includes the costs of developing and procuring hardware, and the annual maintenance expense. Cost penalties for weight and electric power consumption are imposed for each added LRU. Improvement in reliability is …

Space Congress® Proceedings

A high order computer language called ALOFT has been developed for the checkout and operation of complex space oriented equipment such as the proposed NASA Space Shuttle. The flexibility of the language makes it equally suited for use with existing launch vehicles such as Saturn, Titan, etc. and space systems such as Space Station, Viking, etc. With such flexibility it can be assumed that the language will be equally acceptable to future vehicles, space experiments, etc.

Flexibility is obtained by making the language independent of any test system and providing for the user to define a wide variety of words …

Antenna Mechanical And R. F. Systems Measurements And Alignment Using Alsep, Edward A. Dorsett, Lawrence Nicola

Space Congress® Proceedings

A valuable spin-off asset of the lunar exploration program has been the use of the Apollo Lunar Surface Experiments Package (ALSEP) transmitter systems for angular alignment as well as RF systems checks and alignment of AFETR large aperture telemetry antennas.

Accurately known ALSEP antenna coordinates on the lunar surface, together with those of a telemetry antenna on the earth f s surface, makes possible accurate computation of antenna look angles versus time. In order to refine the accuracy of these angles, it was necessary to include the effects of nutations of the earth and librations of the moon. The resulting …

The Application Of Ranging Techniques To Navigation And Traffic Control, Philip M. Diamond

Space Congress® Proceedings

During the last decade a variety of ground- and airbased radio aids have been implemented in efforts to solve major military problems in navigation and guidance, and command, control and communications. Because of significant advances in space technology and avionics, satellite-based systems to provide position-fixing data by means of ranging and range-differencing techniques, and to provide communications capability, have been shown to be feasible and attractive, and to have unique technical and operational advantages. World-wide coverage, essentially instantaneously availability, and threedimensional position-fixing accuracy of a few tens of feet seem feasible. In the civil area, demand for improved communications over …

Cryogenics In Coal Mining, Woods G. Talman

Space Congress® Proceedings

It is somewhat rash for one who is neither a scientist nor a researcher to speak at this Eighth Space Congress. On the other hand pride in modern coal mining and my admiration for coal miners easily overcame any inclination to reject this opportunity.

I hesitate to plunge into examples of noting today's cryogenic technology in coal mining without depicting the coal miner as I know him and touching upon several of the industry f s gravest problems.

Support operations of the Space Station Program may be performed elsewhere; however, centralizing them at KSC has a number of attractive features …

The Use Of Linear Elastic Fracture Mechanics In Viking Pressure Vessel Design, L. D. Guy, F. E. Mershon, R. E. Snyder

Space Congress® Proceedings

Fracture mechanics methodology has developed rapidly over the past 10 years. Although not as yet sufficiently developed for the treatment of complex structures such as aircraft, it is believed that fracture mechanics can provide a sound basis for the design of simple structures such as pressure bottles or tanks. Consequently, the Viking Project has adopted its use for design of all pressure vessels on the Viking spacecraft to assure the long life under sustained pressure necessary for the trip to Mars.

Aerospace Can Help Solve The Ground Transportation Problem, W. C. Galloway, R. C. Uddenberg

Space Congress® Proceedings

Ground transportation has many common features with air and space travel and as a result the experience in aerospace is applicable, but cannot be applied without change. Ground vehicles and aircraft must safely and comfortably transport people, however the weight of the ground vehicle can be increased over the aircraft to realize cost savings. Basic lessons in dynamics, structures and fluid mechanics are applicable. The application of systems engineering disciplines learned on space and missile programs can be very effective. Many new people-mover concepts of current interest are excellent examples of application of system thinking. Finally, aerospace can make the …

An approach to orbital maintenance is examined, using a maintenance element with the capability of providing a pressurized environment for personnel to perform maintenance functions unhampered by pressure suits. Design of an ideal element is reviewed incorporating limited habitability, electronic and pneumatic bench maintenance capability, critical spares storage racks and bins, manipubtors to assist in EVA, and a maintenance/ repair area. The element may be utilized for extended periods of orbital maintenance for providing maintenance services to other orbiting vehicles.

A Checkout Language For Future Space Vehicles, J. W. Meadlock, T. T. Schansman, R. E. Thurber

Space Congress® Proceedings

To support an increased emphasis on automated checkout of future space vehicles, a procedureoriented computer language is required. This language needs to be more user-oriented and needs to have a more complete set of capabilities than existing languages. Such a language, named TOTAL, was developed under contract to NASAKSC. This paper presents an overall view of the language in terms of its major characteristics as derived from the basic design objectives.

Hurricane Seedlings, Neil L. Frank

Space Congress® Proceedings

It is generally recognized that hurricane formation occurs within a pre-existing region of disturbed weather and the dynamical and thermodynamical processes responsible for the disturbed weather are of several different types depending upon the source of energy that feeds the system. Disturbances in which air motion results from cold air underriding and displacing warm air are known as "Baroclinic systems". These are common over subtropical portions of the oceans and are more frequent in the spring and fall. A more common system in the tropics is similar to a simple mechanic heat engine and is driven by the release of …

Arrestment Considerations For The Space Shuttle, Richard V. Parker

Space Congress® Proceedings

Now that aerospace technology has come full circle from aircraft that flew long before any thought of space flight, through space vehicles that could never be mistaken for aircraft, and now back to space vehicles that must also fly as conventional aircraft, it is appropriate to look at a rarely considered, but potentially disastrous, phase of aircraft operations: the overrun accident. That simple fact is that so long as aircraft continue to land on runways, occasionally one will fail to stop within the available distance. Without proper protection, this event can range in import from a red-faced pilot, through fractured …

Spacecraft Housekeeping And Its Relationships To Logistics, Peter H. Needham

Space Congress® Proceedings

Spacecraft housekeeping includes waste collection, containment, pretreatment, transfer, utilization, and disposal. Wastes are categorized as to their sources, production rates, and attributes. Equipment and procedural concepts are identified and similarly categorized so as to facilitate selection for specific mission models. Housekeeping operations are related to the logistics elements of maintenance, up-cargo supply, and downcargo return to earth. Computer programs are useful for housekeeping and logistics data bank maintenance, report preparation, data search, and modeling.

An In Situ Measurement System For Garp Using Ballons, Buoys And A Satellite, John E. Masterson

Space Congress® Proceedings

The goals of the Global Atmospheric Research Program are to increase our understanding of the general circulation of the atmosphere and to develop bases for extended weather prediction. Data to fulfill these goals may come in part from a lowcost random access doppler system using orbiting satellites to recover meteorological and oceanographic data from freely drifting balloons and buoys. Such a system will be used in a scientific study in the tropics and southern hemisphere in 1974 and will involve the Nimbus satellite and some 300 constant-level balloons.

Modular Space Stations, Charles R. Ellsworth, Leon B. Allen

Space Congress® Proceedings

The NASA Space Station Program has recently undergone substantial changes, brought about by the future availability of the Space Shuttle as an earth-to-orbit transportation system. The assembly of a Modular Space Station in earth orbit from elements delivered by the Space Shuttle is feasible and can be accomplished in the late 1970f s or early 1980*s. Low transportation costs, return of modular elements for either refurbishment or update, and incremental growth are major advantages of the modular approach. Initially, a modest three- to six-man Station can be assembled in orbit and, over a period of years, evolve to a larger …

The Theoretical Signal Strength Reduction On The Air Force Eastern Test Range, Charles C. Sellers

Space Congress® Proceedings

Since both metric and non-metric data are transmitted through a missile's antenna system, assurance of an adequate signal level at the ground sites is essential in planning the range instrumentation support of a launch. For this reason a theoretical signal strength reduction is performed at the Air Force Eastern Test Range before every missile launch.

The missile contractor defines the radiation characteristics of each missile-antenna combination in the form of an antenna pattern. The antenna pattern format and the vehicle-antenna coordinate system have been defined by the Inter Range Instrumentation Group. The aspect angles for each tracking site are computed …
