Erosion of Steep River Banks and Time Evolution Towards Equilibrium Channel Shape
A numerical analysis of the time evolution of straight river channels is presented. The bed and bank, material is taken to be coarse, non-cohesive and uniform in size. As a result of the...
Evaluating Damage Detection in Bridges
Several researchers have recently considered using vibration monitoring of highway bridges as a means for detecting structural deterioration. Results to date have demonstrated that the...
Genesis: The Creation of a Lunar Base
A lunar basing scenario that utilizes lunar resources to manufacture lunar concrete modules is considered. An eleven year basing program, starting with initial robotic exploration and...
Conceptual Design of Modules for a Lunar Base
This paper describes the development of cubically shaped aluminum modules which could be variously arranged to form living and working quarters for a lunar base. The module components...
Uses for Lunar Crawler Transporters
This article discusses state-of-the-art crawler transporters and expresses the need for additional research and development for lunar crawlers. The thrust of the paper illustrates how...
Building Lunar Roads?An Overview
Outposts and permanent installations on the moon will need a network of surface roads connecting them. The problem of creating such roads is more challenging than on Earth in most ways,...
Phased Assembly of a European Space Station
This paper discusses a phased assembly approach for a proposed European Space Station utilising a series of constructional payloads that are delivered to orbit in an established sequence...
On-Orbit Assembly of Large Space Structures: A Mars Aerobrake Mock-up Study
As design requirements for space structures become larger in dimension, the issues of shipping and assembling these structures in space become more critical. One example of such a structure...
Cargo Transport to the Lunar Surface Using a Three Rotor Sling
The three rotor sling, a momentum transfer device, is described. The dynamics of multi-rotor systems are explained, and the three rotor system is shown to be favored over one and two rotor...
Ropeway Material Handling Systems for Lunar Mining Sites
The establishment of permanent lunar sites will be a requirement for future space explorations during early missions into space as well as long term. During all stages it will be necessary...
Combustion Synthesis of Advanced Materials
The combustion synthesis of ceramic-metal composites using an in-situ liquid infiltration technique is described. The effect of varying the reactants and their stoichiometry to provide...
Artificial Gravity Augmentation on the Moon and Mars
Extended visits to the moon and Mars will require a base on the surface. Exploration of small planetary neighbors will depend upon the development of a life support system that prevents...
Mars Basing
Transportation options for getting humans to and from Mars are understood much better than are the Mars basing options themselves. Current crew mission designs do not yet integrate planetary...
Characteristics of High-Speed Runway Exits for Airport Design
This paper addresses some of the geometric design and operational characteristics of high-speed runway exists. Lateral and longitudinal runway constraints limiting the use of high-speed...
The Army Aviation Team from a Military Civil Engineer's Perspective
The Technical Session for which this paper is written is 'Airfield Pavements - A Team Effort.' As such, the emphasis on this paper is the United States Army Aviation Team, and not the...
New Seoul Metropolitan Airport
The New Seoul Metropolitan Airport (NSMA), to be built on a man-made island near Seoul, Korea, will have access to the city by bridge, rail, and dedicated freeway. When completed, NSMA...
Management of Design
Denver's new airport uses the services of over 80 separate design firms. The existing airport, Stapleton, could not be expanded to meet the forecasted demand of 1,200,000 operations with...
The Design of the Airside Concourses
The growth of commercial air traffic in the United States has resulted in the development of the 'New Denver International Airport.' the airside concourses were designed by joint venture...
Airport Landside Management: An Unique Airport Specialty
Air transportation has become a common and preferred method of travel, resulting in an ever increasing number of air passengers. The significant growth has resulted in unique and never...
Opportunities for Fixed Rail Service to Airports
